Cassette storage cassette {CASSETTE FOR RECEIVING SUBSTRATE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette for storing a substrate, and more particularly, to a cassette for storing a substrate, which is suitable for reducing rubbing defects caused by foreign substances in a thin liquid crystal display panel using an in plane switching (IPS) method. will be.

Recently, as the demand for various portable electronic devices such as mobile phones, personal digital assistants (PDAs), and notebook computers has exploded, the flat-panel display device having a light and small size that can be applied to the monitor can be used. The demand for panel displays is increasing. Such flat panel displays include liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), and electroluminescent displays (ELDs). ) Is actively studied, but liquid crystal display devices having advantages such as mass production, ease of driving means, and high definition are currently being intensively developed.

The liquid crystal display has various display modes according to the arrangement of liquid crystal molecules, but at present, the liquid crystal display of the twisted nematic (TN) mode is mainly used because of the advantages of easy black and white display, fast response speed, and low driving voltage. The device is in use. In the liquid crystal display of the twisted nematic mode, the liquid crystal molecules oriented horizontally with the substrate are almost perpendicular to the substrate when a voltage is applied. Therefore, there is a problem that the viewing angle is narrowed upon application of voltage due to the refractive anisotropy of the liquid crystal molecules.

In order to solve the viewing angle problem, a liquid crystal display device having various modes having a wide viewing angle characteristic has been proposed, and a transverse electric field type liquid crystal display device has been applied to actual mass production. In the transverse electric field type liquid crystal display device, a pair of electrodes are provided in a pixel to form a transverse electric field substantially parallel to the substrate, thereby aligning the liquid crystal molecules in a plane.

1 is an exemplary view showing a planar configuration of a conventional transverse electric field type liquid crystal display device.

Referring to FIG. 1, the liquid crystal display panel 1 intersects a plurality of gate lines 3 that are regularly spaced apart and are horizontally arranged, and a plurality of data lines 4 that are vertically spaced apart and vertically intersect. The pixels are individually arranged in a rectangular region defined by the intersection of the gate lines 3 and the data lines 4, and arranged in a matrix form.

The thin film transistor 10 is provided at the intersection of the gate line 3 and the data line 4. The thin film transistor 10 includes a gate electrode 11 to which a scan signal is applied from the gate line 3, and a semiconductor layer formed on the gate electrode 11 and activated as a scan signal is applied to form a channel layer ( 12 and a source electrode 13 and a drain electrode 14 formed on the semiconductor layer 12 to which an image signal is applied through the data line 4 to switch an image signal applied to a pixel from the outside. .

In the pixel, a plurality of common electrodes 5 and pixel electrodes 7 arranged substantially parallel to the data line 4 are disposed. In addition, a common line 16 connected to the common electrode 5 is disposed parallel to the gate line 3 in the middle of the pixel, and a pixel electrode line connected to the pixel electrode 7 is disposed on the common line 16. 18 is disposed and overlaps with the common line 16. A storage capacitance is formed by the overlap of the common line 16 and the pixel electrode line 18.

In the transverse electric field type liquid crystal display device configured as described above, the liquid crystal molecules are aligned substantially in parallel with the common electrode 5 and the pixel electrode 7.

When the thin film transistor 10 is operated and a signal is applied to the pixel electrode 7, a transverse electric field substantially parallel to the liquid crystal display panel 1 is generated between the common electrode 5 and the pixel electrode 7. . Since the liquid crystal molecules rotate on the same plane along the transverse electric field, gray level inversion due to the refractive anisotropy of the liquid crystal molecules can be prevented.

FIG. 2 is an exemplary view illustrating a cross-sectional structure of the liquid crystal display panel according to the II ′ cutting line of FIG. 1.

Referring to FIG. 2, the gate electrode 11 is patterned on the upper surface of the first substrate 20, and the gate insulating layer 22 is formed on the entire surface of the first substrate 20 including the gate electrode 11. .

The semiconductor layer 12 is formed on the top surface of the gate insulating layer 22, and the source electrode 13 and the drain electrode 14 are patterned on the top surface of the semiconductor layer 12. A passivation layer 24 is formed on the entire surface of the first substrate 20.

In addition, a plurality of common electrodes 5 are patterned on the first substrate 20, and a pixel electrode 7 and a data line 4 are patterned on the gate insulating layer 22 to form the common electrode 5 and the pixel. A transverse electric field is generated between the electrodes 7.

On the other hand, a black matrix 32 and a color filter layer 34 are formed on the second substrate 30. The black matrix 32 is to prevent light leakage into an area where liquid crystal molecules do not operate. The black matrix 32 is generally formed along the thin film transistor 10 area and the boundary between the pixel and the pixel (ie, the gate line and the data line area). Is formed. The color filter layer 34 is composed of red, green, and blue color layers to implement the color of light transmitted through the liquid crystal molecules. The liquid crystal layer 40 is formed in a space where the first substrate 20 and the second substrate 30 are spaced apart from each other.

In the transverse electric field type liquid crystal display device, a transverse electric field parallel to the liquid crystal display panel 1 is generated by the common electrode 3 and the pixel electrode 5, and the liquid crystal molecules rotate on the same plane along the transverse electric field. Done. Therefore, the gray scale inversion due to the refractive anisotropy of the liquid crystal molecules can be prevented, and as a result, the viewing angle can be improved.

However, in the above-described horizontal electric field type liquid crystal display device, when an electric field is formed perpendicular to the liquid crystal display panel 1 (that is, the direction from the first substrate 20 to the second substrate 30), the liquid crystal layer ( Since it affects the transverse electric field of 40), since the liquid crystal molecules of the liquid crystal layer 40 do not rotate on the same plane, the image of the liquid crystal display device deteriorates, and furthermore, the defect of the liquid crystal display panel is caused.

It is known that the electric field perpendicular to the liquid crystal display panel 1 is formed by static electricity applied to the rear surface of the second substrate 30 (that is, the surface not facing the first substrate 20). The same static electricity is generated by the contact of the human body or other foreign matter after the liquid crystal display panel 1 is commercialized.

In order to remove the static electricity of the second substrate 30 as described above, in the transverse electric field type liquid crystal display device, as shown in FIG. 2, a transparent conductive material is formed on the back surface of the second substrate 30, for example, indium tin oxide (ITO). A conductive layer 56 such as Tin Oxide) was formed. Although not shown in the figure, the conductive layer 56 is grounded to remove static electricity applied to the second substrate 30.

Therefore, in order to fabricate the color filter substrate of the transverse electric field type liquid crystal display panel, first, the conductive layer 56 is formed on the rear surface of the second substrate 30 of transparent insulating material, and then the second substrate 30 is inverted ( The black matrix 32 and the color filter layer 34 must be sequentially formed by overturning.

That is, the conductive layer 56 is formed on the rear surface of the second substrate 30, and then the second substrate 30 is stored in a cassette and transferred to the equipment to be subjected to the subsequent process.

Then, the second substrate 30 stored in the cassette is extracted and inverted, and the black matrix 32 and the color filter layer 34 are sequentially formed.

An alignment layer is formed on the upper surface of the color filter layer 34 and then rubbed to determine the initial alignment direction of the liquid crystal molecules.

Referring to FIG. 3, there is shown a cassette 100 for receiving a second substrate 30 having a conductive layer 56 formed on its rear surface through a robot arm 101 and transferring the same to a device to be subjected to a subsequent process. .

Figure 4 is an exemplary view showing a planar configuration of the cassette 100, Figure 5 is an exemplary view showing a cross-sectional configuration according to the cutting line II-II 'of Figure 4, Figure 6 is a cut III-III' of FIG. It is an example figure which showed the cross-sectional structure along a line.

4 to 6, the vertical supporters 110A to 110F provided on both side surfaces of the cassette 100 correspond to the long sides of the second substrate 30 to be inserted into the cassette 100. and; Vertical axis supports (110G, 110H) provided on the mating surface of the input hole into which the second substrate (30) is inserted into the cassette (100); Slots 120A to 120F are inserted into and coupled to the longitudinal supporters 110A to 110F provided on both sides of the cassette 100 to support the long edges of the second substrate 30, and the cassette 100 is provided. The vertical axis supports 110A to 110C provided on one side of the are provided at positions facing each other with the vertical axis supports 110D to 110F provided on the other side.

At this time, when dividing the cassette 100 into the first to fourth regions 100A to 100D having the same area, the vertical axis supports provided in the first and third regions 100A and 100C of the cassette 100 ( The 110A and 110D are formed to be deflected from the vertical centerline V2 of the first and third regions 100A and 100C in the direction of the vertical centerline V1 of the cassette 100.

In addition, some of the vertical axis supports 110B and 110E of the second and fourth regions 100B and 100D of the cassette 100 are perpendicular to the cassette 100. It is formed at a position corresponding to the vertical axis supports 110A and 110D provided in the first and third regions 100A and 100C of the cassette 100 with respect to the center line V1, and the remaining vertical axis supports 110C and 110F. ) Are formed at positions adjacent to the mating surface of the inlet through which the second substrate 30 is inserted into the cassette 100.

In addition, the vertical supporters 110G and 110H provided on the mating surface of the input hole into which the second substrate 30 is inserted into the cassette 100 have a constant separation distance based on the horizontal center line S1 of the cassette 100. It is provided in the corresponding position.

7 is an exemplary view showing a planar configuration in which the second substrate 30 is accommodated in the cassette 100 as described above.

The cassette 100 is configured as described above to support the long side edge of the second substrate 30 through a plurality of slots 120A to 120F provided in the longitudinal supporters 110A to 110F on both sides.

First to fourth image display portions 30A to 30D are formed on the second substrate 30 at the same time. In this case, the reason why the first to fourth image display parts 30A to 30D are simultaneously formed on the second substrate 30 is that in the manufacture of the liquid crystal display device, a plurality of liquid crystal display panels are simultaneously formed on a large area mother substrate. By cutting into individual unit liquid crystal display panels, material costs are reduced, manufacturing time is shortened, and yield is improved.

In recent years, as the substrate becomes thinner in order to make the liquid crystal display thinner, when the second substrate 30 is accommodated in the cassette 100, the center of the second substrate 30 becomes ground due to the effect of gravity. The phenomenon of bending is occurring.

That is, referring to the exemplary diagrams of FIGS. 8A to 8D, the bending amount of the second substrate 30 is shown when the thickness of the second substrate 30 is gradually reduced.

When the thickness of the second substrate 30 is 0.7t (0.7mm), the second substrate 30 supported by the slots 120A and 120D provided in the vertical axis supports 110A and 110D of the cassette 100 is provided. ) Is centered on the ground by 21mm, 25mm for 0.63t (0.63mm), 31mm for 0.6t (0.6mm), and 40mm or more for 0.5t (0.5mm). If the thickness of 30) is 0.5t (0.5mm), it cannot be stored in the cassette 100.

Therefore, in the related art, when the thickness of the second substrate 30 is 0.5t (0.5 mm), the longitudinal supporters 110A and 110D of the cassette 100 are accommodated to accommodate the second substrate 30 in the cassette 100. Protruding length of the slots (120A, 120D) provided in the increased.

However, foreign matter may be adsorbed on the surface of the second substrate 30 in contact with the slots 120A and 120D, and as described above, when the protruding length of the slots 120A and 120D is increased, Foreign matter may be adsorbed adjacent to the first to fourth image display portions 30A to 30D formed on the substrate 30 or inside the first to fourth image display portions 30A to 30D.

As described above, the black matrix 32 and the color filter layer 34 are formed on the surface of the second substrate 30 supported by the slots 120A and 120D in a subsequent process, and the color filter layer 34 After forming the alignment layer on the upper surface and rubbing is performed to determine the initial alignment direction of the liquid crystal molecules.

Therefore, when the rubbing direction of the second substrate 30 progresses from one long side to the other long side, the second substrate 30 is adjacent to the first to fourth image display units 30A to 30D of the second substrate 30 or the first to first agents. Foreign matter adsorbed inside the four image display units 30A to 30D may cause vertical line defects in the first to fourth image display units 30A to 30D along the rubbing direction.

As described above, when vertical line defects occur in the first to fourth image display units 30A to 30D, not only the image quality of the liquid crystal display panel is deteriorated but also the material cost is increased as the liquid crystal display panel is judged defective and discarded. There was a problem of lowering the yield.

9 to 11, the cassette 200 has an open front face, and the substrate 230 enters and exits, and both sides corresponding to the long side of the substrate 230 and a back side corresponding to one short side of the substrate 230 are provided. A frame 201; First and second vertical shaft supports 210A and 210B spaced apart from each other by a rear surface of the frame 201; Third and fourth longitudinal axis supports 210C and 210D provided at both sides adjacent to the front of the frame 201; Fifth and sixth longitudinal axis supports 210E and 210F provided at centers of both sides of the frame 201; First and second slots 220A and 220B supporting one short side of the substrate 230 inserted and coupled to the first and second vertical axis supports 210A and 210B, respectively; Third and fourth slots 220C and 220D supporting both long sides of the substrate 230 inserted and coupled to the third and fourth vertical axis supports 210C and 210D, respectively; Both sides of the substrate 230 are inserted into and coupled to the fifth and sixth longitudinal supporters 210E and 210F, respectively, and contact the boundary surfaces of the image display parts (not shown) formed on the substrate 230. Consisting of the fifth and sixth slots 220E and 220F.

12 is an exemplary view showing a planar structure in which the substrate 230 is accommodated in the cassette 200 as described above.

The cassette 200 is configured as described above, the substrate 230 through the first and second slots 220A and 220C provided in the first and second vertical shaft supports 210A and 210B on the rear of the frame 201. And a long side edge of the substrate 230 through the third to sixth slots 220C to 220F provided on the third to sixth longitudinal supporters 210C to 210F on both sides of the frame 201. Support.

The substrate 230 is a color filter substrate of the above-described transverse electric field type liquid crystal display panel is applied.

As described above, in the transverse electric field type liquid crystal display panel, liquid crystal molecules are rotated by a transverse electric field between a common electrode and a pixel electrode formed on the thin film transistor array substrate, and a black matrix and a color filter layer are formed on the color filter substrate.

In the transverse electric field type liquid crystal display, a vertical electric field is formed when static electricity is applied to the rear surface of the color filter substrate (that is, the surface not facing the thin film transistor array substrate) and is formed between the common electrode and the pixel electrode. It affects an electric field and deteriorates the image of a liquid crystal display device, and also produces the defect of a liquid crystal display panel.

Accordingly, a conductive layer for removing static electricity such as, for example, indium tin oxide (ITO) or indium zinc oxide (IZO) is formed of a transparent conductive material on the back of the color filter substrate, and the conductive layer is grounded to ground the color filter substrate. The static electricity applied to the back of the was removed.

In order to manufacture the color filter substrate of the transverse electric field type liquid crystal display panel as described above, first, a conductive layer for removing static electricity is formed on the back surface of the transparent insulating material, and then the substrate is stored in a cassette and transferred to the equipment to be subjected to the subsequent process. The substrate stored in the cassette is extracted and inverted, and the black matrix and the color filter layer are sequentially formed.

An alignment layer is formed on the upper surface of the color filter layer and then rubbed to determine the initial alignment direction of the liquid crystal molecules.

Accordingly, the substrate 230 shown in FIG. 12 is accommodated in the cassette 200 in a state where a conductive layer for removing static electricity (not shown in the figure) is formed on the upper surface thereof, and then transferred to the equipment to be subjected to the subsequent process.

In addition, first to fourth image display parts 230A to 230D are simultaneously formed on the substrate 230. In this case, the reason why the first to fourth image display units 230A to 230D are simultaneously formed on the substrate 230 is that in the manufacture of the liquid crystal display device, a plurality of liquid crystal display panels are simultaneously formed on a large area mother substrate and then separated into individual units. By cutting into a liquid crystal display panel, material cost is reduced, manufacturing time is shortened, and a yield is improved.

The fifth and sixth slots 220E and 220F, which are inserted into and coupled to the fifth and sixth longitudinal axis supports 210E and 210F provided on both sides of the frame 201, are provided with the first and second image display units 230A, 230B) and the long side of the substrate 230 are contacted with the boundary regions of the third and fourth image display units 230C and 230D.

A plurality of image display units may be manufactured on the substrate 230, but fifth and sixth slots may be inserted into and coupled to the fifth and sixth longitudinal supporters 210E and 210F provided at both sides of the frame 201. It is preferable to make the boundary regions of the plurality of image display portions contact by the 220E and 220F.

In recent years, as the substrate becomes thinner in order to make the liquid crystal display thinner, a phenomenon in which the substrate housed in the cassette is bent under the influence of gravity is gradually intensified. As shown in FIG. 8A to FIG. When the thickness of the substrate is 0.5t (0.5mm), the substrate is bent by 40 mm or more due to the influence of gravity, so that it cannot be stored in the cassette.

Therefore, in order to accommodate the second substrate 30 having a thickness of 0.5 t (0.5 mm) in the cassette 100, the vertical supporters 110A and 110D of the cassette 100 are conventionally used as shown in FIG. The protruding length of the provided slots 120A and 120D has been increased.

However, foreign matter may be adsorbed on the surface of the second substrate 30 in contact with the slots 120A and 120D, and when the protruding length of the slots 120A and 120D is increased, the second substrate 30 may be formed on the second substrate 30. The foreign matter may be adsorbed adjacent to the first to fourth image display portions 30A to 30D formed in or in the first to fourth image display portions 30A to 30D.

On the surface of the second substrate 30 supported by the slots 120A and 120D, a black matrix 32 and a color filter layer 34 are formed in a subsequent process, and an alignment layer is formed on the upper surface of the color filter layer 34. After forming, rubbing is performed to determine the initial alignment direction of the liquid crystal molecules.

Therefore, in the related art, when the rubbing direction of the second substrate 30 progresses from one long side to the other long side, the second substrate 30 is adjacent to the first to fourth image display units 30A to 30D of the second substrate 30 or the first side. Defects adsorbed inside the fourth image display units 30A to 30D may cause vertical line defects in the first to fourth image display units 30A to 30D along the rubbing direction.

However, the substrate storage cassette according to the present invention, as shown in Figure 12, the first and second slots that are inserted and coupled to the first and second vertical axis support (210A, 210B) provided on the back of the frame 201 As the 220A and 220B support one short side of the substrate 230, the phenomenon in which the substrate 230 is bent under the influence of gravity is alleviated.

In addition, the protruding lengths of the third and fourth slots 220C and 220D inserted into and coupled to the third and fourth vertical axis supports 210C and 210D provided at both sides adjacent to the front of the frame 201 may be increased. In this case, as in the prior art, it is possible to prevent the occurrence of a vertical line defect along the rubbing direction.

That is, the third and fourth slots 220C and 220D may be disposed at one outer side of the first and third image display units 230A and 230C formed on the substrate 230 (ie, a dummy region of the substrate 230). In order to support the substrate 230, foreign matter is adsorbed on the surface of the substrate 230 in contact with the third and fourth slots 220C and 220D, and rubbing is performed from one long side to the other long side of the substrate 230. Even in the case where the vertical line defects occur along the dummy region of the substrate 230, the vertical line defects do not occur in the first and third image display units 230A and 230C.

In addition, even when the protrusion lengths of the fifth and sixth slots 220E and 220F that are inserted into and coupled to the fifth and sixth longitudinal supporters 210E and 210F respectively provided at the centers of both sides of the frame 201 are increased. Similar to the third and fourth slots 220C and 220D, a vertical line defect may be prevented from occurring along the rubbing direction.

That is, the fifth and sixth slots 220E and 220F may be spaced apart from each other by the first and second image display units 230A and 230B and the third and fourth image display units 230C and 230D formed on the substrate 230. Since the long side of the substrate 230 is supported in the boundary region, foreign matter is adsorbed to the surface of the substrate 230 in contact with the fifth and sixth slots 220E and 220F, and the other side of the long side of one side of the substrate 230. Even when rubbing is performed on the long side, vertical line defects occur along the boundary area where the first and second image display units 230A and 230B and the third and fourth image display units 230C and 230D are spaced apart from each other. Vertical line defects do not occur in the fourth image display units 230A to 230D.

Accordingly, the protruding lengths of the third to sixth slots 220C to 220F provided on the third to sixth vertical axis supports 210C to 210F on both sides of the frame 201 may allow the substrate 230 to be inserted into the cassette 200. It can be increased sufficiently within the range of not interfering with the robot arm (not shown in the figure) for transferring to the robot arm.

For example, assuming that the width of the cassette 200 in which the substrate 230 of 880 × 680 mm is accommodated is 690 mm, and the width of the robot arm that transfers the substrate 230 into the cassette 200 is 500 mm, the The protruding lengths of the third to sixth slots 220C to 220F provided on the third to sixth longitudinal supporters 210C to 210F on both sides of the frame 201 may be increased to about 80 to 90 mm.

As described above, the cassette for storing a substrate according to the present invention is provided on both sides of the cassette, even when the protrusion length of the slots supporting the long edges of the substrate is sufficiently increased within the range not to interfere with the robot arm for transferring the substrate. Since it is possible to prevent the occurrence of vertical line defects in the image display portions, it is possible to suppress the phenomenon that the substrate is bent to the ground under the influence of gravity.

Therefore, there is an effect that the process can be advanced in response to the thin substrate.

In addition, there is an effect to improve the image quality of the liquid crystal display panel by preventing the vertical line defects, it is possible to reduce the defect factors of the liquid crystal display panel to reduce the material cost, improve the yield.
