FIG. 4 is a schematic plan view of a structure of a display panel after displacement according to an embodiment of the present invention. FIG. 5A is a schematic cross-sectional view of a display panel corresponding to the line A2′-A2 ′ of FIG. 4. FIG. 5B is a schematic cross-sectional view of the display panel corresponding to the line B2′-B2 ′ of FIG. 4.

When the display panel 100 is bent, pressed, or moved, which causes the first substrate 110 and / or the second substrate 120 to be stressed, the extension amount between the first substrate 110 and the second substrate 120 is different and displacement or This is a case of misalignment, and may be referred to as a misalignment state between the first substrate 110 and the second substrate 120 relative to a normal alignment state. Please refer to FIGS. 4, 5A, and 5B. When the first substrate 110 and the second substrate 120 are displaced, for example, the first substrate 110 and the second substrate 120 may generate a relative displacement substantially along the second direction D2. Then, the first spacer 172 and the second spacer 174 may be substantially moved toward or away from the bump 164 along the second direction D2. Here, in the case of the first gap 172, when the first gap 172 moves substantially close to the bump 164 along the second direction D2 and the relative displacement is between the first inner pitch D11 and the first inner pitch D11 and the bump Between the sum of the width U2 of 164, in the vertical projection direction D3, the vertical projection range of the first gap 172 and the vertical projection range of the bump 164 at least partially overlap, and the first gap 172 contacts the light shielding component 160 correspondingly. At the bump 164 (for example, the first gap 172 contacts the top surface 164s of the bump 164 or the first gap 172 contacts the protective layer or the alignment layer PI on the top surface 164s of the bump 164); and the second gap The vertical projection range of 174 does not overlap with the vertical projection range of the bump 164, and the second spacer 174 does not contact the corresponding bump 164 of the light shielding component 160. For example, the first spacer 172 is displaced and can contact part or all of the top surface 164s of the bump 164 (or contact the protective layer or the alignment layer PI located on the top surface 164s of the bump 164); the second spacer 174 displacement, and the vertical projection of the top surface 174s of the second spacer 174 is within the projection range of the light shielding layer 162 (when the relative displacement is less than the second outer distance D22) or the vertical projection of the top surface 174s of the second spacer 174 At least partly exceeds the projection range of the light-shielding layer 162 (when the relative displacement is greater than the second outer distance D22). Viewed from another aspect, the second spacer 174 can be seen by the relative displacement without exceeding the fourth edge 1623 of the light shielding layer 162 or crossing the fourth edge 1623 of the light shielding layer 162 and entering the display range of the sub-pixel 150 (ie Is not shielded by the light shielding layer 162).

Here, when the displacement amount of the first spacer 172 is less than or substantially equal to the sum of the width U2 of the bump 164 and the first inner distance D11, the first spacer 172 may be abutted against the bump 164, in other words, the first The distance between the substrate 110 and the second substrate 120 will increase, so that the top surface 174s of the second spacer 174 is spaced from the surface 162s of the light shielding layer 162, so that the top surface 174s of the second spacer 174 and the surface of the light shielding layer 162 162s has a gap G in the vertical projection direction. In different implementation forms, since the alignment layer PI is conformally covered on the outer surfaces of the light shielding member 160 and the spacer 170, the gap G can substantially ignore the effect of the thickness of the alignment layer PI. Viewed from another aspect, the gap G may refer to the distance between the top surface 174s of the second gap 174 and the surface 162s of the light shielding layer 162, or it may refer to the distance between the top surface 174s of the second gap 174 The distance between the alignment layer PI and the alignment layer PI on the surface 162s of the light shielding layer 162.

When the first spacer 172 continues to move past the bump 164 and the second spacer 174 is displaced into the display range (not shown) of the sub-pixel 150, because the second spacer 174 and the light-shielding layer 162 are projected perpendicularly There is a gap G in the direction D3, and the second gap 174 scrapes off the surface of the light-shielding layer 162 during the previous displacement (such as the light-shielding layer 162 or the alignment layer PI on the surface 162s of the light-shielding layer 162 or The protective layer, etc.) will remain within the range of the light-shielding layer 162 (that is, it does not exceed the fourth edge 1623), so that these pollutants can be prevented from being moved into the display range of the sub-pixel 150, thereby avoiding affecting the display panel 100. Display quality.

In one embodiment, when the external force disappears, the first substrate 110 and the second substrate 120 return to their original positions, which may be referred to as the first substrate 110 and the second substrate. When the substrate 120 is in the normal alignment state, the projection of the top surface 172s of the first spacer 172 is located between the first edge 132 and the bump 164 and does not overlap the bump 164. Similarly, the projection of the top surface 174s of the second spacer 174 is located between the second edge 134 and the bump 164 and does not overlap the bump 164.

In some embodiments, in order to be able to contact at least the first spacer 172, the bump 164 may have various designs. In one embodiment, the bumps 164 may be designed in a stripe shape and an extension direction of the bumps 164 is substantially the same as an extension direction of the light shielding layer 162. In an embodiment, the center line L1 of the bump 164 and the center line L2 of the light shielding layer 162 are substantially parallel and coincide, as shown in FIG. 2. In another embodiment, in the vertical projection direction of the first substrate 110, the center line of the bump 164 does not coincide with the center line of the light-shielding layer 162 (not shown), and the bumps 164 are far away from both sides of the light-shielding layer 162 For example, the range of the bump 164 does not touch the edges 1621 and 1623 of the light shielding layer 162 adjacent to the side surface of the bump 164. In an embodiment, as shown in FIG. 2, in the vertical projection direction of the first substrate 110, the area A2 of the bump 164 (eg, the vertical projection range of the bump 164) occupies the area A1 of the light shielding layer 162 (eg: The ratio of the vertical projection range of the light-shielding layer 162 is about 5-40%.

In addition, the shape of the bump 164 may have various designs. In an embodiment, the bump 164 may be a rectangular parallelepiped, as shown in FIG. 6A. In addition, in order to facilitate the first gap 172 to be displaced along the side of the bump 164 to the top surface 164s of the bump 164, so that the first gap 172 and the bump 164 abut (for example, the first gap 172 abuts against the protrusion). Block 164). In an embodiment, the bumps 164 may be designed to taper from the bottom to the top surface 164s, such as a growing trapezoid (as shown in FIG. 3A and FIG. 3B), where the bumps 164 are adjacent to the first Both sides of a spacer 172 and a second spacer 174 may be inclined planes or curved surfaces. In addition, in another embodiment, the top surface 164s of the bump 164 may be a plane (as shown in FIG. 6A), or both sides and the top surface of the bump 164 are continuous arc surfaces (as shown in FIG. 6B). Show).

In addition, in an embodiment, the bumps 164 and the light-shielding layer 162 may be integrally formed. Here, the materials of both the light-shielding layer 162 and the bumps 164 may be the same type and manufactured in the same manufacturing process. In addition, for process considerations, the bumps 164 and the light-shielding layer 162 may also be manufactured in different manufacturing processes. For example, a photoresist material or a metal material is first formed on the inner surface 112 of the first substrate 110 as a pad. The object 166 is then covered with a layer of black photoresist material on the elevated object 166, as shown in FIG. 6C. Here, the material of the light shielding component 160 may include different types of materials, such as black photosensitive resin, various colors Photoresist materials and / or metal materials.

In one embodiment, the first spacer 172 and the second spacer 174 both serve as main photo spacers, and the thickness S1 of the first spacer 172 and the thickness S2 of the second spacer 174 are substantially the same. When the first substrate 110 and the second substrate 120 are not displaced (for example, in a normal alignment state), the top surface 172s of the first spacer 172 contacts the corresponding light shielding layer 162 of the light shielding component 160, and the second spacer The top surface 174s of 174 contacts the corresponding light-shielding layer 162 of the light-shielding component 160. For example, the top surface 172s of the first spacer 172 and the top surface 174s of the second spacer 174 contact the surface 162s of the light shielding layer 162, or the top surface 172s of the first spacer 172 and the top of the second spacer 174. The protective layer or the alignment layer PI on the surface 174s is in contact with the protective layer or the alignment layer PI on the surface 162s of the light shielding layer 162. In different implementations, since the alignment layer PI is conformally covered on the outer surfaces of the light-shielding device and the spacer, the relationship between the thickness S1 and the thickness S2 can basically ignore the effect of the thickness of the alignment layer PI.

When the first substrate 110 and the second substrate 120 are not displaced (for example, in a normal alignment state), the top surface 172s of the first spacer 172 does not contact the corresponding light shielding layer 162 of the light shielding component 160 and the first spacer The top surface 174s of 172 is between the top surface 164s of the bump 164 and the surface 162s of the light-shielding layer 162, and the top surface 174s of the second spacer 174 contacts the corresponding light-shielding layer 162 of the light-shielding component 160 (for example, the second spacer The top surface 174s of 174 is in contact with the surface 162s of the light-shielding layer 162 or the alignment layer PI or the protective layer in contact with the surface 162s of the light-shielding layer 162). In this embodiment, the thickness T1 of the bump 164 is greater than the difference between the thickness S1 of the first spacer 172 and the thickness S2 of the second spacer 174. In yet another embodiment, the thickness of the bump 164 The thickness T1 is, for example, about 0.3 μm, but is not limited thereto.

In this embodiment, please refer to FIGS. 7, 8A, and 8B. When the first substrate 110 and the second substrate 120 are not bent, pressed, or moved by an external force, etc., between the first substrate 110 and the second substrate 120 When no displacement or misalignment occurs, in the vertical projection direction D3 of the first substrate 110, the projection of the first spacer 172 (for example: the auxiliary spacer) and the projection of the second spacer 174 (for example: the main spacer) Both are located within the projection range of the light-shielding layer 162 and are respectively located on different sides of the bumps 164 substantially parallel to the center line of the first electrode line 130. In an embodiment, the projection of the top surface 172s of the first spacer 172 (eg, the auxiliary spacer) is located between the first edge 132 and the bump 164 and does not overlap with the bump 164. Similarly, the projection of the top surface 174s of the second spacer 174 (eg, the main spacer) is located between the second edge 134 and the bump 164 and does not overlap with the bump 164. The first outer distance D12 is greater than the first inner distance D11, and the second outer distance D22 is greater than the second inner distance D21. Moreover, the first inner pitch D11 is smaller than the second outer pitch D22, and the first outer pitch D12 is larger than the second inner pitch D21.

FIG. 9 is a schematic plan view of a structure of a display panel after displacement according to another embodiment of the present invention. FIG. 10A is a schematic cross-sectional view of a display panel corresponding to the line C2-C2 ′ in FIG. 9. FIG. 10B is a schematic cross-sectional view of the display panel corresponding to the line D2-D2 ′ in FIG. 9.

When the display panel 200 is bent, squeezed, or moved, the first substrate 110 and the second substrate 120 are subjected to different forces, and the extension amount between the first substrate 110 and the second substrate 120 is different, causing displacement or misalignment. Situation. Please refer to FIGS. 9, 10A, and 10B. When the first substrate 110 and the second substrate 120 are displaced, for example, the first substrate 110 and the second substrate 120 are displaced along the second direction D2, then the first The spacer 172 and the second spacer 174 are displaced toward or away from the bump 164 along the second direction D2. Here, in the case of the first spacer 172 (for example, an auxiliary spacer), when the first spacer 172 moves near the bump 164 in the second direction D2 and the relative displacement is between the first inner distance D11 and the first inner distance Between the distance D11 and the sum of the width U2 of the bump 164, in the vertical projection direction D3 of the first substrate 110, the first spacer 172 and the bump 164 at least partially overlap and contact the corresponding bump 164 of the light shielding component 160 (For example, the first spacer 172 contacts the surface 162s of the bump 164 or the protective layer or the alignment layer PI located on the top surface 164s of the bump 164), and the second spacer 174 (such as the main spacer) and the bump 164 does not overlap and does not contact the corresponding bump 164 of the light shielding component 160 (for example, the second gap 174 does not contact the surface 162s of the bump 164 or the protective layer or the alignment layer PI on the top surface 164s of the bump 164) . For example, the first spacer 172 is displaced and may contact the top surface 164s of part or all of the bumps 164 (or contact the protective layer or the alignment layer PI on the top surface 164s of the part or all of the bumps 164). ; And the second spacer 174 is displaced, and the vertical projection range of the top surface 174s of the second spacer 174 is within the vertical projection range of the light shielding layer 162 (for example, when the relative displacement is smaller than the second outer distance D22) or The vertical projection range of the top surface 174s of the two gaps 174 at least partially exceeds the vertical projection range of the light shielding layer 162 (for example, when the relative displacement is greater than the second outer distance D22) and enters the range of the sub-pixel 150. Viewed from another aspect, the second spacer 174 can be seen by the relative displacement without exceeding the fourth edge 1623 of the light-shielding layer 162 or crossing the fourth edge 1623 of the light-shielding layer 162 and entering the display range of the sub-pixel 150 (for example, : Where not shielded by the light shielding layer 162).

Here, when the displacement amount of the first spacer 172 is less than or substantially equal to the sum of the width U2 of the bump 164 and the first inner distance D11, the first spacer 172 may be abutted against the bump 164, in other words, the first The distance between the substrate 110 and the second substrate 120 will increase, so that the top surface 174s of the second spacer 174 is spaced from the surface 162s of the light shielding layer 162, so that the top surface 174s of the second spacer 174 and the surface of the light shielding layer 162 162s has a gap G in the vertical projection direction D3.

When the first spacer 172 continues to move past the bump 164 and the second spacer 174 is displaced into the display range (not shown) of the sub-pixel 150, because the second spacer 174 and the light-shielding layer 162 are projected perpendicularly There is a gap G in the direction D3, and the second spacer 174 scrapes off the surface of the light shielding layer 162 during the previous displacement (for example, the light shielding layer 162, the alignment layer PI on the surface 162s of the light shielding layer 162, or protection). Pollutants such as layers) will stay within the range of the light-shielding layer 162 (for example, it does not exceed the fourth edge 1623), so it is possible to avoid moving these pollutants into the display range of the sub-pixel 150, thereby avoiding affecting the display panel 200 Display quality.

Next, please refer to FIGS. 7, 8A, and 8B again. When the external force disappears, the first substrate 110 and the second substrate 120 return to their original positions, that is, the first substrate 110 and the second substrate 120 are in a normal alignment state. At this time, the projection of the top surface 172s of the first spacer 172 (eg, the auxiliary spacer) is located between the first edge 132 and the bump 164 and does not overlap with the bump 164. Similarly, the projection of the top surface 174s of the second spacer 174 (eg, the main spacer) is located between the second edge 134 and the bump 164 and does not overlap with the bump 164.

FIG. 11 is a schematic structural diagram of a spacer according to an embodiment of the present invention. For ease of explanation, FIG. 11 only illustrates the structural diagrams of the spacers 172 and 174, the second substrate 120, and the alignment layer PI. The arrangement of the spacers (eg, the first spacer 172 and / or the second spacer 174) shown in FIG. 11 is substantially the same as the spacers shown in FIG. 3A, and the difference lies in the system of the spacers shown in FIG. 11 A plurality of film layers are stacked on each other and an alignment layer PI is covered on the outside of the stacked film layers. For example, it may be a color filter layer of different colors stacked on each other or a plurality of photoresist layers stacked on each other. In addition, the first spacer 172 and the second spacer 174 may be cylindrical, conical, pyramidal, etc., and may be adjusted according to actual needs.

In summary, in the display panel of the embodiment of the present invention, bumps are provided on the light-shielding layer of the first substrate, and the first and second spacers on the second substrate extend along the first electrode line. The directions are staggered, and the first spacer and the second spacer are respectively disposed corresponding to the corresponding bumps. When the first substrate and the second substrate are displaced, the first spacer can be brought against the bump during the displacement process, so that there is a gap between the second spacer and the light shielding layer. Therefore, the second spacer is less likely to scratch the alignment layer or the protective layer during the displacement process, or the pollutants caused by the second spacer to scratch the alignment layer or the protective layer during the displacement process are less likely to enter the sub-pixels. Range to avoid affecting the display quality of the display panel.
