Optionally, the display panel 100 further comprises a protective layer 15, and the protective layer 15 is used to protect the first filter layer 12.

[0032] Figure 2 Fig. 1 shows a schematic diagram of a film layer structure of a display panel provided by an embodiment of the present disclosure, please refer to Figure 1 and Figure 2 The display panel 100 comprises a first substrate 10, and an array layer 11 is formed on the first substrate 10.

When a signal voltage is applied to the gate electrode 114, the switching transistor 113 is turned on, and a data voltage on a data line is provided to the pixel electrode 112 through the switching transistor 113. An electric field formed by the pixel electrode 112 and the common electrode 111 drives the liquid crystal molecules to rotate, so as to control the light transmittance through the sub-pixel.

[0039] Please refer to Figure 3 and Figure 5The second filter layer 21 on the second substrate 20 includes a plurality of upper color resist portions 22, and the upper color resist portions 22 in the second filter layer 21 include a first upper color resist 221 and a second upper color resist 222 along a direction parallel to a plane on which the display panel 100 is located, wherein the first upper color resist 221 is connected to the second upper color resist 222, the first upper color resist 221 is provided with a first opening 231, and the second upper color resist 222 is provided with a second opening 232, that is, at least part of the first upper color resist 221 and the second upper color resist 222 are located between the first opening 231 and the second opening 232 along the second direction D2. Figure 5 In the specific embodiment, the first opening 231 provided by the first upper color resist 221 and the second opening 232 provided by the second upper color resist 222 are of the same size, which does not represent the size relationship of the openings of the R (red color resist), the openings of the B (blue color resist), and the openings of the G (green color resist). In other embodiments, the sizes of the first opening 231 and the second opening 232 can be different according to the color or transmittance of the color resist, and the specific size can be determined according to actual needs.

[0040] Please refer to Figure 3 and Figure 4 The first filter layer 12 on the first substrate 10 includes a plurality of light shielding portions 14 and a plurality of lower color resist portions 13, the lower color resist portions 13 include a first lower color resist 131 and a second lower color resist 132, and the first lower color resist 131 and the second lower color resist 132 are different in color. Figure 4 Only the light shielding portion 14 is in a mesh structure, and in other embodiments, the light shielding portion 14 can also be in other structures, which are not limited in the present disclosure. Please refer to Figure 4 The first filter layer 12 includes the light shielding portion 14 and the lower color resist portion 13, the lower color resist portion 13 is filled with color resist, and the color resist includes red color resist, green color resist, and blue color resist. It should be noted that the sizes of the red color resist, the green color resist, and the blue color resist in the first filter layer 12 can be the same or different. Figure 4 In the specific embodiment, the red color resist R, the green color resist G, and the blue color resist B are arranged periodically along the second direction D2, and the color resist of each color is arranged in a single color along a direction perpendicular to the second direction.

[0041] In an optional embodiment provided by the present disclosure, the first lower color resist 131 in the first filter layer 12 overlaps the first opening 231 in the second filter layer 21, and the second lower color resist 132 in the first filter layer 12 overlaps the second opening 232 in the second filter layer 21 in the direction perpendicular to the plane where the display panel 100 is located. The color of the first lower color resist 131 is the same as that of the first upper color resist 221, and the color of the second lower color resist 132 is the same as that of the second upper color resist 222. The light emitted from the second lower color resist 132 is different from the light emitted from the first lower color resist 131 to the first opening 231. If the light emitted from the second lower color resist 132 enters the first opening 231, color mixing will occur with the light in the first opening 231, resulting in color deviation of the light emitted from the first opening 231 and affecting the display effect. The first upper color resist 221 can block the light emitted from the second lower color resist 132 from entering the first opening 231, thereby reducing color mixing and improving the display effect. The color of the first lower color resist 131 is the same as that of the first upper color resist 221, and the light of the first lower color resist 131 can be emitted through the first upper color resist 221, thus being conducive to increasing the large-viewing-angle light emission amount of the panel. By introducing the first upper color resist 221, the large-viewing-angle light emission amount is improved, and color mixing is avoided. Similarly, the light emitted from the first lower color resist 131 is different from the light emitted from the second lower color resist 132 to the second opening 232. If the light emitted from the first lower color resist 131 enters the second opening 232, color mixing will occur with the light in the second opening 232, resulting in color deviation of the light emitted from the second opening 232 and affecting the display effect. The second upper color resist 222 can block the light emitted from the first lower color resist 131 from entering the second opening 232, thereby reducing color mixing and improving the display effect. The color of the second lower color resist 132 is the same as that of the second upper color resist 222, and the light of the second lower color resist 132 can be emitted through the second upper color resist 222, thus being conducive to increasing the large-viewing-angle light emission amount of the panel. By introducing the second upper color resist 222, the large-viewing-angle light emission amount is improved, and color mixing is avoided.

[0042] Figure 6 Fig. 2 shows a schematic diagram of emitted light of a display panel provided by an embodiment of the present disclosure, Figure 7 Fig. 3 shows another schematic diagram of emitted light of a display panel provided by an embodiment of the present disclosure, and Figure 6As shown, when the first substrate 10 and the second substrate 20 are accurately aligned, the solid arrows in the figure are the light exit directions of the display panel 100 at the front view angle, where the "front view angle" can be understood as the angle at which the display panel 100 is observed from the side of the light exit surface of the display panel 100 along the first direction D1, and the dashed arrows in the figure are the light exit directions of the display panel 100 at the side view angle, where the "side view angle" can be understood as the angle at which the display panel is observed from the side of the light exit surface of the display panel 100 in a direction other than the first direction D1. As can be seen from the figure, due to the presence of the second filter layer 21, light rays beyond the range of the opening 23 can pass through the first upper color resist 221. Figure 7 As shown, when the first substrate 10 and the second substrate 20 are accurately aligned, the solid arrows in the figure are the light exit directions of the display panel 100 at the front view angle, where the "front view angle" can be understood as the angle at which the display panel 100 is observed from the side of the light exit surface of the display panel 100 along the first direction D1, and the dashed arrows in the figure are the light exit directions of the display panel 100 at the side view angle, where the "side view angle" can be understood as the angle at which the display panel is observed from the side of the light exit surface of the display panel 100 in a direction other than the first direction D1. As can be seen from the figure, due to the presence of the second filter layer 21, light rays beyond the range of the opening 23 can pass through the first upper color resist 221. That is, when the first upper color resist 221 serves as the light filtering structure of the first lower color resist 131 and the light blocking structure of the second lower color resist 132, and the second upper color resist 222 serves as the light filtering structure of the second lower color resist 132 and the light blocking structure of the first lower color resist 131, the first upper color resist 221 can simultaneously serve as the light filtering structure of the first lower color resist 131 and the light blocking structure of the second lower color resist 132, and the second upper color resist 222 can simultaneously serve as the light filtering structure of the second lower color resist 132 and the light blocking structure of the first lower color resist 131, which is conducive to increasing the alignment margin of the first substrate 10 and the second substrate 20 and reducing the light ray crosstalk between adjacent sub-pixels 108, thereby improving the display effect.

[0043] Please refer to Figures 3 to 7 The display panel 100 provided by the present disclosure includes a first light blocking portion 141 between the first lower color resist 131 and the second lower color resist 132 along the second direction D2.

[0044] In the first direction D1, the first light-shielding portion 141 overlaps with the first upper color resist 221 and the second upper color resist 222.

[0045] Specifically, in the direction parallel to the plane on which the display panel 100 is located, the first light-shielding portion 141 is located between the first lower color resist 131 and the second lower color resist 132, in the direction perpendicular to the plane on which the display panel 100 is located, the first light-shielding portion 141 in the first filter layer 12 on the first substrate 10 overlaps with the first upper color resist 221 in the second filter layer 21 on the second substrate 20, and the first light-shielding portion 141 in the first filter layer 12 on the first substrate 10 overlaps with the second upper color resist 222 in the second filter layer 21 on the second substrate 20, that is, in the first direction D1, the first upper color resist 221 and the second upper color resist 222 both overlap with the first light-shielding portion 141 located between the first lower color resist 131 and the second lower color resist 132, the first upper color resist 221 is located above the first light-shielding portion 141, and the second upper color resist 222 is located above the first light-shielding portion 141, in this way, by arranging the first light-shielding portion 141 to overlap with the first upper color resist 221 and the second upper color resist 222 in the first direction D1, the overlapping area of the first upper color resist 221 and the first lower color resist 131 in the second direction D2 can be increased, the overlapping area of the second upper color resist 222 and the second lower color resist 132 in the second direction D2 can be increased, which is conducive to the passing of light when the upper color resist portion 22 serves as a filter structure, improves the alignment margin of the first substrate 10 and the second substrate 20, and reduces the aperture 23 rate loss of the first substrate 10 and the second substrate 20.

[0046] Please continue to refer to Figure 3 The display panel 100 provided by the present disclosure is provided, in the second direction D2, the light-shielding portion 14 located on the side of the first lower color resist 131 away from the second lower color resist 132 is a second light-shielding portion 142, and the distance H1 between the first light-shielding portion 141 and the second light-shielding portion 142 is greater than or equal to the width H2 of the first aperture 231 in the second direction D2.

[0047] Specifically, the first substrate 10 is formed with the first filter layer 12, the first filter layer 12 includes the light shielding part 14 and the lower color resistance part 13, in the direction parallel to the plane where the display panel 100 is located, the second light shielding part 142 is located on the side of the first lower color resistance 131 away from the second lower color resistance 132, that is, the second light shielding part 142 is adjacent to the first lower color resistance 131, the first lower color resistance 131 is located between the second light shielding part 142 and the first light shielding part 141, and for the same reason, the second lower color resistance 132 is located between the first light shielding part 141 and the second light shielding part 142. The disclosure only limits the relative position of the first lower color resistance 131, the second lower color resistance 132, the first light shielding part 141 and the second light shielding part 142, and does not limit the absolute position; in the direction parallel to the plane where the display panel 100 is located, the distance H1 between the first light shielding part 141 and the second light shielding part 142 is greater than or equal to the width H2 of the first opening 231. The lower color resistance part 13 structure can be overlapped with the light shielding part 14 when formed, so when the distance H1 between the first light shielding part 141 and the second light shielding part 142 is greater than or equal to the width H2 of the first opening 231, it means that the width of the lower color resistance part 13 in the first filter layer 12 on the first substrate 10 is greater than or equal to the width H2 of the first opening 231 in the second filter layer 21 on the second substrate 20. In this way, the alignment allowance of the first substrate 10 and the second substrate 20 can be increased, and the opening 23 rate loss can be reduced, but the light range emitted from the first light shielding part 141 and the second light shielding part 142 is greater than the light range that can be accommodated by the first opening 231. In combination with the first upper color resistance 221 and the first lower color resistance 131 of the same color in the foregoing embodiment, the second upper color resistance 222 and the second lower color resistance 132 of the same color, for the light exceeding the accommodation range of the first opening 231, increase the emission range, and the second color resistance 222 with a color different from the first color resistance 221 acts as a light shielding structure, reduces the cross color between adjacent sub-pixels 108, and improves the display effect. In this way, by setting the distance H1 between the first light shielding part 141 and the second light shielding part 142 to be greater than or equal to the width H2 of the first opening 231 in the second direction D2, the substrate alignment allowance can be improved, the light emission range can be increased in combination with the first color resistance 221 filtering or light shielding dual role, and the light mixing between sub-pixels 108 of different colors can be reduced, and the display effect can be improved.

[0048] It should be noted that the "width of the first opening 231 in the second direction D2" refers to the length of the first opening 231 in the direction parallel to the plane where the display panel 100 is located.

[0049] In an optional embodiment provided by the present disclosure, the distance between the first light shielding portion 141 and the second light shielding portion 142 can also be smaller than the width of the first opening 231; at this time, the light range emitted from the lower color resistance portion 13 is smaller than the light emission range that can be accommodated by the first opening 231, and the light color mixing between adjacent sub-pixels 108 can be reduced to a greater extent, and the display effect is improved.

[0050] Figure 8 Fig. 1 shows a schematic diagram of a display panel structure provided by an embodiment of the present disclosure. As shown in Figure 8 The present disclosure provides a display panel 100, the light shielding portion 14 between the first lower color resistance 131 and the second lower color resistance 132 is a first light shielding portion 141, and the distance h2 between the first opening 231 and the second opening 232 is greater than or equal to the width h1 of the first light shielding portion 141 in the second direction D2.

[0051] Specifically, the display panel 100 includes a first substrate 10, the first substrate 10 is formed with a first filter layer 12, the first filter layer 12 includes a lower color resistance portion 13 and a light shielding portion 14, the lower color resistance portion 13 includes first lower color resistance 131 and second lower color resistance 132 with different colors, and the light shielding portion 14 between the first lower color resistance 131 and the second lower color resistance 132 is a first light shielding portion 141 in the direction parallel to the plane where the first substrate 10 is located; the display panel 100 includes a second substrate 20 arranged in parallel and opposite to the first substrate 10, the second substrate 20 is formed with a second filter layer 21, the second filter layer 21 includes an upper color resistance portion 22 and an opening 23, the upper color resistance portion 22 includes first upper color resistance 221 and second upper color resistance 222 with different colors, the first upper color resistance 221 is provided with a first opening 231, the second upper color resistance 222 is provided with a second opening 232, and the distance h2 between the first opening 231 and the second opening 232 is greater than or equal to the width h1 of the first light shielding portion 141 in the direction parallel to the plane where the display panel 100 is located, that is, in the second direction D2, the width of the upper color resistance portion 22 between the first opening 231 and the second opening 232 is greater than or equal to the width h1 of the first light shielding portion 141. It should be noted that the opening 23 is provided in the upper color resistance portion 22, and the projection of the upper color resistance portion 22 on the second substrate 20 is annular in the first direction D1, and the width of the upper color resistance portion 22 can be the actual width of the annular portion.

[0052] Due to the limitation of the production process, the first substrate 10 and the second substrate 20 can have an alignment offset. When the distance h2 between the first opening 231 and the second opening 232 is greater than or equal to the width h1 of the first light shielding portion 141 in the second direction D2, the first upper color resist 221 and the first lower color resist 131 can overlap in the first direction D1. Since the first upper color resist 221 and the first lower color resist 131 have the same color, the light emitted from the first lower color resist 131 can pass through the first upper color resist 221, and the display panel 100 will not weaken the emitted light. If the distance h2 between the first opening 231 and the second opening 232 is less than the width h1 of the first light shielding portion 141 in the second direction D2, there is a part of the first light shielding portion 141 between the first lower color resist 131 and the first upper color resist 221 in the direction parallel to the plane on which the display panel 100 is located, and there is a part of the first light shielding portion 141 between the second lower color resist 132 and the second upper color resist 222. This will cause visual problems such as black state of the display picture, discontinuity of the display picture, and the like. Therefore, by setting the distance h2 between the first opening 231 and the second opening 232 to be greater than or equal to the width h1 of the first light shielding portion 141 in the second direction D2, the visual problems such as black state of the display picture, discontinuity of the display picture, and the like can be reduced, the alignment allowance of the first substrate 10 and the second substrate 20 can be increased, and the product yield can be improved.

[0053] Figure 9 Another display panel structure provided by the embodiment of the present disclosure is shown in the schematic diagram of the display panel structure. Please refer to Figure 9 The present disclosure provides a display panel 100. In the first direction D1, the first upper color resist 221 and the second upper color resist 222 include an overlapping portion 223.

[0054] Specifically, the display panel 100 includes a second substrate 20, and a second filter layer 21 is formed on the second substrate 20, the second filter layer 21 includes an upper color resistance part 22, the upper color resistance part 22 is provided with an opening 23, the upper color resistance part 22 includes a first upper color resistance 221 and a second upper color resistance 222 connected to each other, the first upper color resistance 221 is provided with a first opening 231, the second upper color resistance 222 is provided with a second opening 232, in an optional embodiment provided by the present disclosure, in a direction perpendicular to a plane in which the display panel 100 is located, the first upper color resistance 221 and the second upper color resistance 222 include an overlapping part 223, the first upper color resistance 221 and the second upper color resistance 222 are located between the first opening 231 and the second opening 232, a distance between the first opening 231 and the second opening 232 is greater than or equal to a width of the first light shielding part 141 in the second direction D2, that is, a sum of widths of the first upper color resistance 221 and the second upper color resistance 222 in the second direction D2 is greater than or equal to the width of the first light shielding part 141 in the second direction D2, since the first upper color resistance 221 and the second upper color resistance 222 include the overlapping part 223, the widths of the first upper color resistance 221 and the second upper color resistance 222 including the overlapping part 223 can be set relatively flexibly with respect to the widths of the first upper color resistance 221 and the second upper color resistance 222 not including the overlapping part 223, and the requirements on actual production processes are reduced; in this way, along the first direction D1, by setting the overlapping part 223 on the first upper color resistance 221 and the second upper color resistance 222, the overlapping part 223 can be used as a light shielding structure, light rays emitted from the first lower color resistance 131 toward the overlapping part 223 cannot be emitted, and light rays emitted from the second lower color resistance 132 toward the overlapping part 223 cannot be emitted, which is equivalent to increasing the area of the light shielding structure between adjacent sub-pixels, and is conducive to reducing color mixing and color deviation.

[0055] It should be noted that, along the first direction D1, when the first upper color resistance 221 and the second upper color resistance 222 include the overlapping part 223, the total width of the first upper color resistance 221 and the second upper color resistance 222 including the overlapping part 223 is less than the sum of the width of a single first upper color resistance 221 and the width of a single second upper color resistance 222.

[0056] Figure 10 The figure shows a relative width diagram of the overlapping part and the first upper color resistance in a display panel provided by an embodiment of the present disclosure, please refer to Figure 10 The present disclosure provides a display panel 100, a width L2 of the overlapping part 223 in the second direction D2 is less than or equal to 1 / 2 of a width L1 of the first upper color resistance 221 in the second direction D2.

[0057] Specifically, along the direction perpendicular to the plane where the display panel 100 is located, the first color resist 221 and the second color resist 222 include an overlapping part 223, and along the second direction D2, the width of the overlapping part 223 is less than or equal to half of the width of the first color resist 221 in the second direction D2, where the width of the first color resist 221 in the second direction D2 refers to, along the second direction D2, in the same color resist part 22, the distance from the end of the first color resist 221 towards the first opening 231 to the farthest distance where the first color resist 221 meets the second color resist 222. In some embodiments, when the width of the first color resist 221 is equal to the width of the second color resist 222, the width L2 of the overlapping part 223 in the color resist part 22 is less than or equal to half of the width L2 of the first color resist 221 or the width of the second color resist 222. Since the overlapping part 223 is the overlapping of part of the first color resist 221 and part of the second color resist 222 in the first direction D1, there are two different color resists in the overlapping part 223 in the first direction D1, and the overlapping part 223 only has light blocking function and does not have light filtering function. When the width L2 of the overlapping part 223 is greater than half of the width L1 of the first color resist 221, the overlapping part 223 is too wide, and both the overlapping part 223 and the second color resist 222 belong to light blocking structures relative to the first lower color resist 131, the light blocking range is too large, which reduces the light emitted from the first lower color resist 131 and affects the display effect. Therefore, by setting the width L2 of the overlapping part 223 in the second direction D2 to be less than or equal to half of the width L1 of the first color resist 221 in the second direction D2, the width of the first color resist 221 and the second color resist 222 can be increased and the process difficulty can be reduced, and at the same time, the light blocking range can be as small as possible and the blocking of the emitted light can be reduced.

[0058] Please continue to refer to Figure 10 The display panel 100 provided by the present disclosure includes a first light blocking part 141 between the first lower color resist 131 and the second lower color resist 132, and the width L2 of the overlapping part 223 is less than the width h1 of the first light blocking part 141.

[0059] Specifically, the display panel 100 includes a first substrate 10, a first filter layer 12 is formed on the first substrate 10, the first filter layer 12 includes a lower color resistance part 13 and a light shielding part 14, the lower color resistance part 13 includes a first lower color resistance 131 and a second lower color resistance 132 which are different in color, the first light shielding part 141 is located between the first lower color resistance 131 and the second lower color resistance 132 in a direction parallel to the plane where the second substrate 20 is located, the width L2 of the overlapping part 223 is less than the width h1 of the first light shielding part 141, if the width L2 of the overlapping part 223 is greater than or equal to the width h1 of the first light shielding part 141, the light shielding range of the overlapping part 223 is too large, the range of light rays emitted from the first filter layer 12 is blocked by the overlapping part 223 is larger, the range of light rays emitted from the upper color resistance part 22 is narrower, which affects the display effect; in this way, by setting the width L2 of the overlapping part 223 in the second direction D2 to be less than the width h1 of the first light shielding part 141 in the second direction D2, the light shielding range of the overlapping part 223 as a light shielding structure can be reduced, the emitted light rays of the upper color resistance part 22 are improved, and the display defects caused by the overlapping part 223 being too wide are reduced.

[0060] Please continue to refer to Figure 10 The display panel 100 provided by the present disclosure has the following advantages: the width L1 of the first upper color resistance 221 in the second direction D2 is less than the width h1 of the first light shielding part 141 in the second direction D2, and / or the width L3 of the second upper color resistance 222 in the second direction D2 is less than the width h1 of the first light shielding part 141 in the second direction D2.

[0061] Specifically, in an optional embodiment provided by the present disclosure, the width L1 of the first upper color resist 221 in the direction parallel to the plane where the display panel 100 is located is less than the width h1 of the first light shielding portion 141; in another optional embodiment provided by the present disclosure, the width L3 of the second upper color resist 222 in the direction parallel to the plane where the display panel 100 is located is less than the width h1 of the first light shielding portion 141; in yet another optional embodiment provided by the present disclosure, the width L1 of the first upper color resist 221 in the direction parallel to the plane where the display panel 100 is located is less than the width h1 of the first light shielding portion 141, and the width L3 of the second upper color resist 222 in the direction parallel to the plane where the display panel 100 is located is less than the width h1 of the first light shielding portion 141; that is, in the first direction D1, there are both the first upper color resist 221 and the second upper color resist 222 above the first light shielding portion 141, the first upper color resist 221 above the first light shielding portion 141 and having the same color as the first lower color resist 131 allows the light emitted from the first lower color resist 131 to pass through, and the second upper color resist 222 above the first light shielding portion 141 and having a different color from the first lower color resist 131 blocks the light emitted from the first lower color resist 131 from passing through; if the width L1 of the first upper color resist 221 is greater than or equal to the width h1 of the first light shielding portion 141, the range of light emitted from the first upper color resist 221 is too large, which is likely to cause color mixing of light between adjacent sub-pixels 108; if the width L3 of the second upper color resist 222 is greater than or equal to the width h1 of the first light shielding portion 141, the range of light emitted from the second upper color resist 222 is too large, which is likely to cause color mixing of light between adjacent sub-pixels 108; thus, by setting the width L1 of the first upper color resist 221 in the second direction D2 to be less than the width h1 of the first light shielding portion 141 and / or setting the width L3 of the second upper color resist 222 in the second direction D2 to be less than the width h1 of the first light shielding portion 141, the color mixing of light between adjacent sub-pixels 108 can be reduced while the range of emitted light is as large as possible, and the display effect can be improved.
