The first aperture region 510 may be formed through a portion of the side member 441 from a first outer surface 451 of the side member 441 in the second direction D2, the first outer surface 451 facing the planar region 481 of the rear plate 480.

The second aperture region 520 may open toward the curved region 482 of the rear plate 480. The second hole region 520 may be formed to extend from any one of the third direction D3 and the fourth direction D4 to the remaining one of the third direction D3 and the fourth direction D4, and the third direction D3 and the fourth direction D4 may be substantially perpendicular to or cross the first direction D1. The second aperture region 520 may be formed to overlap the curved region 482 of the rear plate 480 and pass through the second outer surface 452. The second hole region 520 may be formed through a portion of the side member 441 from a second outer surface 452 of the side member 441 in the third direction D3 or the fourth direction D4, the second outer surface 452 facing the curved region 482 of the rear plate 480.

The connection region 530 may be disposed in an intersection region of the first hole region 510 and the second hole region 520. The connection region 530 may spatially connect the first hole region 510 and the second hole region 520. Because the first hole region 510 and the second hole region 520 are connected to each other by the connection region 530, the adhesive channel 500 may be formed in an "L" shaped channel structure passing through a portion of the side member 441.

The first adhesive member 410 is filled in the adhesive channel 500, and thus may have a shape corresponding to the adhesive channel 500. For example, when the bonding channel 500 has an "L" shape, at least a portion of the first bonding member 410 may have an "L" shape along the shape of the bonding channel 500. The first adhesive member 410 may include a first adhesive region 411 filled in the first hole region 510, a second adhesive region 412 filled in the second hole region 520, and a third adhesive region 413 filled in the connection region 530.

The second adhesive region 412 of the first adhesive member 410 may extend toward the curved region 482 of the rear plate 480 instead of toward the second outer surface 452 of the side member 441. The second adhesive region 412 of the first adhesive member 410 may be disposed between the curved region 482 of the rear plate 480 and the side member 441. The second adhesive region 412 of the first adhesive member 410 may couple the curved region 482 of the rear plate 480 and the side member 441. The first adhesive member 410 may contact the curved region 482 of the rear plate 480. A portion of the first adhesive member 410 contacting the curved region 482 of the rear plate 480 may be formed in a curved form along the curved region 482.

The second adhesive member 420 may be disposed on the first adhesive member 410 filled in the first hole region 510. As an example, as shown in fig. 6a, the second adhesive member 420 may be formed on the first adhesive region 411 of the first adhesive member 410 to have a width greater than that of the first adhesive region 411. The second adhesive member 420 may contact the flat region 481 of the rear plate 480. At least a portion of the second adhesive member 420 contacting the flat region 481 of the rear plate 480 may be formed in a flat form along the flat region 481. As another example, as shown in fig. 6b, the second adhesive member 420 may be formed on the first adhesive region 411 of the first adhesive member 410 toward the second adhesive region 412. The second adhesive member 420 may be formed on a second outer surface 452 of the side member 441, the second outer surface 452 being disposed between the first hole region 510 and the second hole region 520. The second adhesive member 420 may overlap the first adhesive region 411 and the second adhesive region 412 of the first adhesive member 410. The second adhesive member 420 may contact the first adhesive region 411 and the second adhesive region 412 of the first adhesive member 410.

According to an embodiment, the second adhesive member 420 may have an integral structure without an interface (interface) with the first adhesive member 410. According to another embodiment, the second adhesive member 420 may form an interface with the first adhesive member 410.

According to still another embodiment, a coloring material or a fluorescent material may be added to at least any one of the first and second adhesive members 410 and 420. For example, since a coloring material or a fluorescent material is added to the second adhesive member 420, an application (application) defect or an adhesion defect of the second adhesive member 420 may be recognized by naked eyes.

According to still another embodiment, the second adhesive member 420 may be formed of the same or dissimilar material as the first adhesive member 410. At least any one of the first and second adhesive members 410 and 420 may be formed of a liquid type adhesive. For example, the liquid adhesive may be formed of a Polyurethane (PUR) -based material, a acryl-based material, or a synthetic resin-based material, or may be formed of a combination thereof (e.g., pur+acryl-based material or pur+synthetic resin-based material). PUR-based materials are reactive adhesives that cause reactions with moisture, and the curing process may be performed in a space at a specified temperature and humidity. The synthetic rubber-based material is a non-reactive adhesive and the curing process may be performed in room temperature space.

According to yet another embodiment, at least any one of the first and second adhesive members 410 and 420 may be a pressure sensitive adhesive (PSHA). For example, at least any one of the first and second adhesive members 410 and 420 may be a pressure sensitive hot melt adhesive (PSHA). At least any one of the first and second adhesive members 410 and 420 may be a thermoplastic adhesive that adheres by cold solidification after being heated and applied in a molten state. Since at least any one of the first and second adhesive members 410 and 420 exhibits bonding/adhesive properties even through only a cooling/curing process, a separate additional process may not be required. The softening point of at least any one of the first and second adhesive members 410 and 420 may be 150 degrees (c) to 200 degrees (c) and they have high heat resistance retention and high viscosity, so stable application is possible.

According to still another embodiment, the main substance of at least any one of the first and second adhesive members 410 and 420 may be a synthetic rubber-based material or a plasticizer. The synthetic rubber-based material is a thermoplastic rubber whose main substrate is a styrene block copolymer, and may be an adhesive exhibiting adhesive properties by using a natural resin and a petroleum resin. The synthetic rubber-based material is lipid-free solids and may not produce toxic Volatile Organic Compounds (VOCs), such as toluene, xylene, ethylbenzene, or styrene, including isocyanates. Mineral oil may be used as the plasticizer.

According to still another embodiment, at least any one of the first and second adhesive members 410 and 420 may be formed as a pressure sensitive adhesive, which has a lower manufacturing cost than that of the double-sided tape type adhesive, and thus may save costs. The embodiment including at least one of the first and second adhesive members 410 and 420 may maintain high adhesive force as compared to the comparative example including the double-sided tape type adhesive, as shown in table 1.

TABLE 1

According to still another embodiment, after at least any one of the rear plate 480 and the side member 441 is detached to adhere an object to the adhesive member 400 formed of a pressure-sensitive adhesive, residues of the adhesive member 400 may not be generated on the adhered object. The first adhesive member 410 and the second adhesive member 420 can be easily detached from at least any one of the rear plate 480 and the side member 441. Fig. 7a, 7b, 7c, and 7d are views illustrating adhesive channels of an electronic device according to various embodiments of the present disclosure.

Referring to fig. 7a to 7d, the adhesive channel 500 may include a first hole region 510, a second hole region 520, and a connection region 530.

The first hole region 510 may be formed to face the inside of the side member 441 from the first outer surface 451 of the side member 441. The first hole region 510 may be formed such that at least any one of the first transverse length W11 and the first longitudinal length W12 becomes wider as it becomes farther from the connection region 530. The first transverse length W11 of the first aperture region 510 may be equal to or greater than the first longitudinal length W12 of the first aperture region 510. For example, the first transverse length W11 of the first aperture region 510 may be 1.5mm to 2.0mm, and the first longitudinal length W12 of the first aperture region 510 may be 1.0mm to 1.5mm.

The second hole region 520 may be formed to face the inside of the side member 441 from the second outer surface 452 of the side member 441. The second hole region 520 may be formed such that at least any one of the second transverse length W21 and the second longitudinal length W22 becomes wider as it becomes farther from the connection region 530. The second transverse length W21 of the second aperture region 520 may be equal to or greater than the second longitudinal length W22 of the second aperture region 520. The second lateral length W21 of the second aperture region 520 may be equal to or different from the first lateral length W11 of the first aperture region 510. The second longitudinal length W22 of the second aperture region 520 may be equal to or different from the first longitudinal length W12. For example, the second transverse length W21 of the second aperture region 520 may be 1.5mm to 2.0mm, and the second longitudinal length W22 of the second aperture region 520 may be 1.0mm to 1.5mm.

The first hole region 510 may be formed to be surrounded by the first inner surface 701, the second inner surface 702, the third inner surface 703, and the fourth inner surface 704. The first inner surface 701 may face the second inner surface 702, and the first bore region 510 is disposed between the first inner surface 701 and the second inner surface 702. The first inner surface 701 may be formed to face the exterior of an electronic device (e.g., the electronic device 401 of fig. 4). The second inner surface 702 may be formed to face the interior of the electronic device. The third inner surface 703 may be connected to one side of the first inner surface 701 and one side of the second inner surface 702 therebetween. The fourth inner surface 704 may face the third inner surface 703, while the first aperture region 510 is disposed between the fourth inner surface 704 and the third inner surface 703. The fourth inner surface 704 may be connected to and between opposite sides of the first inner surface 701 and opposite sides of the second inner surface 702.

The second bore region 520 may be formed to be surrounded by the fifth inner surface 705, the sixth inner surface 706, the seventh inner surface 707, and the eighth inner surface 708. The fifth inner surface 705 may face the sixth inner surface 706, while the second bore region 520 is arranged between the fifth inner surface 705 and the sixth inner surface 706. The fifth inner surface 705 may be formed to face the outside of the electronic device. Sixth inner surface 706 may be formed to face the interior of the electronic device. The fifth inner surface 705 may be included in an extension region 442 of the side member 441, the extension region 442 extending a certain width WA toward the outside of the electronic device, rather than toward the sixth inner surface 706. The width WA of the extension region 442 may be determined based on the curvature of the curved region 482 of the rear plate 480. As the curvature of the curved region 482 becomes greater, the width WA of the extended region 442 may become smaller. The seventh inner surface 707 may be connected to one side of the fifth inner surface 705 and one side of the sixth inner surface 706 therebetween. The eighth inner surface 708 may face the seventh inner surface 707, with the second aperture region 520 disposed between the eighth inner surface 708 and the seventh inner surface 707. Eighth inner surface 708 may be connected to and between an opposite side of fifth inner surface 705 and an opposite side of sixth inner surface 706.

As the first hole region 510 is distant from the connection region 530, the width of the first hole region 510 may become larger. At least any one of the first inner surface 701, the second inner surface 702, the third inner surface 703, and the fourth inner surface 704 defined by the first hole region 510 may be formed to be inclined with respect to the first imaginary plane 751 and the second imaginary plane 752, the first imaginary plane 751 and the second imaginary plane 752 being substantially parallel to a center line extending in a depth direction (e.g., D2) of the first hole region 510. The gradient angle defined by at least one of the first inner surface 701, the second inner surface 702, the third inner surface 703, and the fourth inner surface 704 and the imaginary planes 751 and 752 may be 0.5 to 1 degree.

According to an embodiment, as shown in fig. 7d, the first inner surface 701 may be formed to be inclined so as to become farther from the second inner surface 702 as the first inner surface 701 becomes closer to the first outer surface 451. The first gradient angle θ1 defined by the first imaginary plane 751 and the first inner surface 701, which are located between the first inner surface 701 and the second inner surface 702, may be 0.5 to 1 degree. The second inner surface 702 may be formed to be inclined so as to become farther from the first inner surface 701 as the second inner surface 702 becomes closer to the first outer surface 451. The second gradient angle θ2 defined by the second imaginary plane 752 substantially parallel to the first imaginary plane 751 and the second inner surface 702 may be 0.5 to 1 degrees. The first gradient angle θ1 and the second gradient angle θ2 may be the same or different.

As the second hole region 520 is distant from the connection region 530, the width of the second hole region 520 may become larger. At least any one of the fifth inner surface 705, the sixth inner surface 706, the seventh inner surface 707, and the eighth inner surface 708 defined by the second hole region 520 may be formed to be inclined with respect to the third imaginary plane 753 and the fourth imaginary plane 754, the third imaginary plane 753 and the fourth imaginary plane 754 being substantially parallel to a center line extending in a depth direction (e.g., D2) of the second hole region 520. The gradient angle defined by at least one of the fifth inner surface 705, the sixth inner surface 706, the seventh inner surface 707, and the eighth inner surface 708 and the imaginary planes 753 and 754 may be 0.5 to 1 degrees.

According to another embodiment, as shown in fig. 7d, the fifth inner surface 705 may be formed to be inclined so as to become farther from the sixth inner surface 706 as the fifth inner surface 705 becomes closer to the second outer surface 452. The third gradient angle θ3 defined by the third imaginary plane 753 and the fifth inner surface 705, which are substantially perpendicular to the first imaginary plane 751, may be 0.5 to 1 degree. The sixth inner surface 706 may be formed to be inclined such that as the sixth inner surface 706 becomes closer to the second outer surface 452, the sixth inner surface 706 becomes farther from the fifth inner surface 705. The fourth gradient angle θ4 defined by the fourth imaginary plane 754 and the sixth inner surface 706, which are substantially perpendicular to the second imaginary plane 752, may be 0.5 to 1 degrees. The third gradient angle θ3 and the fourth gradient angle θ4 may be the same or different.

The connection region 530 may define a plurality of inner corner surfaces 711 and 712 in the adhesive channel 500. The connection region 530 may include a first inner corner surface 711 and a second inner corner surface 712 facing each other. The first inner corner surface 711 may face the second inner corner surface 712 in a direction facing the exterior of the electronic device. The first inner corner surface 711 may connect the first inner surface 701 and the fifth inner surface 705 facing the outside of the electronic device. The second inner corner surface 712 may face the first inner corner surface 711 in a direction facing the interior of the electronic device. The second inner corner surface 712 may connect the second inner surface 702 and the sixth inner surface 706 facing the interior of the electronic device.

Either one of the first and second inner corner surfaces 711 and 712 may be curved in a direction defining an obtuse angle. The remaining one of the first and second inner corner surfaces 711 and 712 may be curved in a direction defining an acute angle, a right angle, or an obtuse angle. The first inner corner surface 711 may be curved in a direction defining an obtuse angle so as not to obstruct a flow direction of the liquid-type adhesive constituting the first adhesive member 410 (e.g., discharge from the first hole region to the second hole region). For example, the first inner corner surface 711 may be bent in a direction defining an obtuse angle to be formed into a bent form, and the second inner corner surface 712 may be bent in a direction defining a right angle. As another example, as shown in fig. 7d, the first and second inner corner surfaces 711 and 712 may be curved in a direction defining an obtuse angle to be formed in a curved form.

The separation distance "d" between the first inner corner surface 711 and the second inner corner surface 712 may be formed to be smaller than at least any one of the first lateral length W11, the second lateral length W21, the first longitudinal length W12, and the second longitudinal length W22. The separation distance "d" between the first and second inner corner surfaces 711 and 712 may be formed to have a large size so as not to obstruct the flow direction of the liquid adhesive constituting the first adhesive member 410 (e.g., the flow from the first hole region 510 to the second hole region 520). The distance "d" between the apex of the first inner corner surface 711 and the apex of the second inner corner surface 712 may be a minimum of 0.5mm or more. For example, the separation distance "d" between the apex of the first inner corner surface 711 and the apex of the second inner corner surface 712 may be 0.9mm to 1.1mm.

According to yet another embodiment, the center of the radius of curvature of the first inner corner surface 711 and the center of the radius of curvature of the second inner corner surface 712 may be located at the same position. The radius of curvature R1 of the first inner corner surface 711 may be greater than the radius of curvature of the second inner corner surface 712. The radius of curvature of the first inner corner surface 711 may be greater than the radius of curvature R2 of at least any one of the first hole region 510 and the second hole region 520. For example, the first inner corner surface 711 may have a radius of curvature R1 of 0.9 to 1.1.

The minimum thickness "T" of the side member 441 surrounding the adhesive channel 500 may be designed in consideration of a sufficiently high strength so as not to be damaged when the side member 441 contacts the first adhesive member 410, the second adhesive member 420, and the rear plate 480. The minimum thickness "T" of the side member 441 may correspond to a distance between a first vertex P1 between the second inner surface 702 and the second outer surface 452 and a second vertex P2 between the sixth inner surface 706 and the second outer surface 452. For example, the thickness "T" of the side member 441 may be a minimum value of 0.6mm to 0.8 mm.

Fig. 8a and 8b are views illustrating first and second adhesive members of an electronic device according to various embodiments of the present disclosure.

Referring to fig. 8a and 8b, when the first adhesive member 410 filled in the side member 441 is viewed from above, the first adhesive member 410 may be implemented in a circular shape, an elliptical shape, a polygonal shape, or a polygonal shape with rounded corners. The first adhesive member 410 may be implemented in various shapes and structures, and the shape, structure, and number of the first adhesive member 410 are neither restricted nor limited in the present disclosure.

A plurality of first adhesive members 410 may be formed in the side member 441 of the case 440. For example, as shown in fig. 8a, one first adhesive member 410 may be formed in each of the right region 4411, the left region 4412, the upper region 4413, and the lower region 4414 of the side member 441.

Each of the plurality of first adhesive members 410 disposed in the right region 4411 of the side member 441 may be disposed to be spaced apart from an adjacent first adhesive member 410 by a certain first gap g1. Each of the plurality of first adhesive members 410 disposed in the left region 4412 of the side member 441 may be disposed to be spaced apart from an adjacent first adhesive member 410 by a specific second gap g2. Each of the plurality of first adhesive members 410 disposed in the upper region 4413 of the side member 441 may be disposed to be spaced apart from an adjacent first adhesive member 410 by a specific third gap g3. Each of the plurality of first adhesive members 410 disposed in the lower region 4414 of the side member 441 may be disposed to be spaced apart from an adjacent first adhesive member 410 by a certain fourth gap g4. The first, second, third and fourth gaps g1, g2, g3 and g4 may have the same or different sizes. At least any one of the first gap g1, the second gap g2, the third gap g3, and the fourth gap g4 may be maintained at a minimum of 10mm or more. For example, at least any one of the first gap g1, the second gap g2, the third gap g3, and the fourth gap g4 may be maintained at 10mm to 15mm.

The corner region 801 of the side member 441 may be thicker than the rest of the side member 441 except for the corner region 801, and thus it may be relatively difficult to form the adhesive channel 500. The adhesive channel 500 may be formed in the remaining region of the side member 441 except for the corner region 801. The first adhesive member 410 may be filled in the adhesive channel 500 formed in the remaining region of the side member 441 except for the corner region 801.

The second adhesive member 420 may be formed on at least any one of the right region 4411, the left region 4412, the upper region 4413, and the lower region 4414 of the side member 441. The second adhesive member 420 may be formed on the side member 441 filled with the first adhesive member 410 along the circumference of the side member 441.

Fig. 9 is a perspective view illustrating an electronic device including a banks member according to embodiments of the present disclosure, and fig. 10a and 10b are cross-sectional views illustrating various embodiments of the banks member shown in fig. 9 according to various embodiments of the present disclosure.

Fig. 9, 10a, and 10b may illustrate an electronic device (e.g., electronic device 401 of fig. 4) including a dividing wall member 910 disclosed in the present disclosure. The dividing wall member 910 may be disposed outside of the second bore region 520. The dividing wall member 910 may be disposed on the extension region 442 of the side member 441. At least a portion of the dividing wall member 910 may not overlap the sixth inner surface 706 of the side member 441.

The dividing wall member 910 may be disposed on the fifth inner surface 705 defined by the second bore region 520 and may protrude toward the sixth inner surface 706. The size of the dividing wall member 910 may be equal to or less than the second lateral length W21 of the second bore region 520. The height "H" of the dividing wall member 910 may be lower than the second longitudinal length W22 of the second bore region 520.

The dividing wall member 910 may have a semicircular shape as shown in fig. 10a, or may have a polygonal shape as shown in fig. 10 b. The partition wall member 910 may be formed of the same material as or different from the material of the side member 441. For example, the partition wall member 910 may be integrally formed with the side member 441 using the same material as the side member 441.

The dividing wall member 910 may restrict the flow of the liquid adhesive constituting the first adhesive member 410 before the rear plate 480 is attached to the side member 441. An appropriate amount or more of the first adhesive member 410 may be prevented from overflowing outside the second hole region 520 before attaching the rear plate 480 to the side member 441. Because the first adhesive member 410 may be sufficiently filled in the adhesive channel 500 due to the partition wall member 910, an adhesive force between the rear plate 480 and the side member 441 using the first adhesive member 410 may be enhanced. When the rear plate 480 is pressed by the side member 441, a certain amount of the first adhesive member 410 may be discharged to the outside of the second hole region 520 by the pressing force, and the first adhesive member 410 may contact the curved region 482 of the rear plate 480.

Fig. 11 is a view illustrating an electronic device including a side member having a convex-concave surface according to an embodiment of the present disclosure.

Referring to fig. 11, the side member 441 disclosed in the present disclosure may define at least any one of the plurality of inner surfaces 701, 702, 705 and 706 defined by the adhesive channel 500 as a convex-concave surface in the form of a convex-concave. Although fig. 11 shows that the first inner surface 701, the second inner surface 702, the fifth inner surface 705, and the sixth inner surface 706 are convex-concave surfaces, the present disclosure is not limited thereto. That is, at least any one of the plurality of surfaces defined in the interior of the adhesive channel 500 may be a convex-concave surface. For example, the first inner surface 701, the second inner surface 702, the third inner surface (e.g., the third inner surface 703 of fig. 7 a), the fourth inner surface (e.g., the fourth inner surface 704 of fig. 7 a), the fifth inner surface 705, the sixth inner surface 706, the seventh inner surface (e.g., the seventh inner surface 707 of fig. 7 a), the eighth inner surface (e.g., the eighth inner surface 708 of fig. 7 a), the first inner corner surface (e.g., the first inner corner surface 711 of fig. 7 d), and the second inner corner surface (e.g., the second inner corner surface 712 of fig. 7 d) may be convex-concave surfaces. As another example, fifth inner surface 705, sixth inner surface 706, seventh inner surface 707, eighth inner surface 708, first inner corner surface 711, and second inner corner surface 712 may be convex-concave surfaces. As another example, fifth inner surface 705, sixth inner surface 706, seventh inner surface 707, and eighth inner surface 708 may be convex-concave surfaces.

The convex-concave surface may include a concave region 1101 and a convex region 1102. Concave regions 1101 may be disposed between protruding regions 1102. When forming the first adhesive member 410, the protruding region 1102 may restrict the flow of the liquid type adhesive constituting the first adhesive member 410. Due to the protruding region 1102, an appropriate amount or more of the first adhesive member 410 may be prevented from overflowing to the outside of the second hole region 520. Because the first adhesive member 410 may be sufficiently filled in the adhesive channel 500 due to the protruding region 1102, an adhesive force between the rear plate 480 and the side member 441 using the first adhesive member 410 may be enhanced.

According to an embodiment, the protruding region 1102 may be formed of the same or different material as that of the side member 441. For example, the protruding region 1102 may be integrally formed with the side member 441 with the same material as the side member 441. According to another embodiment, the convex-concave surface including the protruding region 1102 may be an etched surface.

Referring to fig. 12a to 12e, the adhesive channel 500 may include a first hole region 510, a second hole region 520, and a connection region 530. The first hole region 510 may be an injection hole through which the liquid type adhesive 1212 forming the first adhesive member 410 is injected. The second hole region 520 may be a discharge hole through which the liquid-type adhesive forming the first adhesive member 410 is discharged toward the curved region 482 of the rear plate 480. The connection region 530 may be a direction conversion region for discharging the liquid type adhesive in a discharge direction different from the injection direction of the liquid type adhesive.

In operation 1201 shown in fig. 12a, the nozzle 1211 of the liquid type applicator may be aligned with the first aperture region 510 of the adhesive channel 500. The first liquid adhesive 1212 may be discharged to the first hole region 510 through the nozzle 1211. The first liquid-type adhesive 1212 may be formed of a Polyurethane (PUR) -based material, a acryl-based material, or a synthetic resin-based material, or may be formed of a combination thereof (e.g., pur+acryl-based material or pur+synthetic resin-based material).

In operation 1202 shown in fig. 12b, as the first liquid-type adhesive 1212 passes through the connection region 530, the flow direction of the first liquid-type adhesive 1212 may be switched to the second hole region 520.

In operation 1203 shown in fig. 12c, since the first liquid type adhesive 1212 is filled even in the second hole region 520, the first adhesive member 410 including the first liquid type adhesive 1212 may be filled in the adhesive channel 500. Even the first adhesive member 410 filled in the second hole region 520 and the first outer surface 451 disposed around the first hole region 510 may be stepped with each other.

In operation 1204 shown in fig. 12d, since the second liquid type adhesive is discharged through a nozzle (e.g., a nozzle of fig. 12 a) of the liquid type adhesive applying apparatus, the second adhesive member 420 may be formed. The second adhesive member 420 may be formed on the first adhesive member 410 along the side member 441. The second adhesive member 420 may fill a stepped region between the first adhesive member 410 and the first outer surface 451. The second adhesive member 420 may protrude farther than the first outer surface 451. The second liquid type adhesive forming the second adhesive member 420 may be formed of the same or different material as that of the first liquid type adhesive 1212.

In operation 1205 shown in fig. 12e, the rear plate 480 may be coupled to the side members 441 through the first adhesive member 410 and the second adhesive member 420. The curved region 482 of the rear plate 480 may be coupled to the side member 441 by the first adhesive member 410, and the flat region 481 of the rear plate 480 may be coupled to the side member 441 by the second adhesive member 420. When the rear plate 480 is pressed by the side member 441, a certain amount of the first adhesive member 410 may be discharged to the outside of the second hole region 520 by the pressing force, and the first adhesive member 410 may contact the curved region 482 of the rear plate 480. Due to the pressing force generated when the rear plate 480 is pressed to the side member 441, the second adhesive member 420 may be brought into contact with the flat region 481 of the rear plate 480, the width of the contact being greater than the width of the first adhesive member 410 filled in the first hole region 510.

According to an embodiment, the first adhesive member 410 may contact the back plate 480 for a first open time after the first liquid type adhesive 1212 is discharged into the adhesive channel 500. For example, the first liquid adhesive 1212 may be coupled to the back plate 480 in a first open time of 4 minutes or less. The first adhesive member 410 may have thixotropic properties for a first open time that is the time allowed until it contacts the rear plate 480. Thixotropic properties may be those that remain applied despite the low viscosity due to strong surface tension.

The second adhesive member 420 may be adhered to the rear plate 480 for a second open time after the second liquid type adhesive is discharged into the first adhesive member 410. The second adhesive member 420 may have thixotropic properties for a second open time that is the time allowed until it contacts the rear plate 480. Because the second liquid-type adhesive forming the second adhesive member 420 is applied after the first liquid-type adhesive 1212, it can be coupled to the rear plate 480 in a second open time shorter than the first liquid-type adhesive 1212.

In accordance with various embodiments of the present disclosure, the structure in which the adhesive channels 500 are formed in the side members 441 facing the curved region 482 and the flat region 481 of the rear plate 480 has been mainly described, but the second adhesive channels may be additionally formed in the side members 441 facing the curved region and the flat region of the display 430 (e.g., 470).
