Figure 1 The present disclosure provides a display panel 100, comprising: a first substrate 10, a liquid crystal layer 30, and a second substrate 20, wherein the liquid crystal layer 30 is located between the first substrate 10 and the second substrate 20;

[0031] In the first direction D1, the opening 23 overlaps the lower color resist portion 13, wherein the first direction D1 is perpendicular to the plane where the display panel 100 is located. Optionally, the display panel 100 further includes a protective layer 15, and the protective layer 15 is used to protect the first filter layer 12.

[0032] Figure 2 FIG. 1 is a schematic diagram of a film structure of a display panel provided by an embodiment of the present disclosure. Please refer to FIG. Figure 1 and Figure 2 The display panel 100 includes a first substrate 10, an array layer 11 is formed on the first substrate 10, and the side of the array layer 11 facing the second substrate 20 includes a liquid crystal layer 30. Exemplarily, the array layer 11 includes an active layer 115, a gate insulating layer 01, a gate electrode 114, an interlayer insulating layer 02, a source-drain electrode layer, a first filter layer 12, a common electrode 111, a passivation layer PV, and a pixel electrode 112, which are sequentially formed on the first substrate 10. Specifically, the active layer 115 is formed on the first substrate 10, the gate insulating layer 01 is formed on the active layer 115, and the gate insulating layer 01 exists between the gate electrode 114 and the active layer 115.

Among them, the gate electrode 114 controls the conduction and cutoff of the switch transistor 113. When the signal voltage is applied to the gate electrode 114, the switch transistor 113 is turned on, and the data voltage on the data line is provided to the pixel electrode 112 through the switch transistor 113. The electric field formed by the pixel electrode 112 and the common electrode 111 drives the liquid crystal molecules to rotate to control the light transmittance passing through the sub-pixel. Please combine Figure 1 The light emitted by the backlight module 40 is filtered to form an image, and finally a liquid crystal display is realized. Figure 1 The solid arrow in the middle indicates that the light emitted from the backlight module 40 can pass through the color blocking portion 22 in the second filter layer 21 as the filter structure of the sub-pixel after passing through the sub-pixel; Figure 1 The dashed arrow in the middle indicates that the light emitted from the backlight module 40 is blocked by the color blocking portion 22 which serves as the light blocking structure of the adjacent sub-pixel after passing through the sub-pixel adjacent to the sub-pixel; this can increase the light emission angle range of the sub-pixel while reducing the light crosstalk between adjacent sub-pixels.

[0033] It should be noted that, in this embodiment, the first filter layer 12 is arranged between the source-drain electrode layer and the pixel electrode 111 in the array layer 11. Optionally, the first filter layer 12 can also be located in other film layers of the array layer 11. The present disclosure does not limit the specific position of the first filter layer 12.

[0034] Please continue to refer to Figure 1 The array layer 11 includes a first filter layer 12, which is located on the side of the first substrate 10 facing the liquid crystal layer 30. The first filter layer 12 includes a shading portion 14 and a lower color resist portion 13. The shading portion 14 is used to shield metal parts such as metal wiring in the array layer 11 to prevent the metal wires from reflecting when ambient light is irradiated to these metal wires, thereby affecting the display quality of the picture. The lower color resist portion 13 is used to filter the light emitted by the backlight source.

In a direction perpendicular to the plane where the display panel 100 is located (such as D1 in the figure), the opening 23 in the second filter layer 21 on the second substrate 20 overlaps with the lower color resistance portion 13 on the first substrate 10; in this way, the first filter layer 12 is respectively arranged on the first substrate 10, the first filter layer 12 includes a light shielding portion 14 and a lower color resistance portion 13, and the second filter layer 21 is arranged on the second substrate 20, the second filter layer 21 includes an upper color resistance portion 22 and an opening 23, the opening 23 and the lower color resistance portion 13 overlap in the first direction D1, and the light passing through the lower color resistance portion 13 can be emitted through the opening 23. In addition, the upper color resistance portion 22 can block the light emitted from the lower color resistance portion 13 in the adjacent sub-pixel, thereby reducing the light crosstalk between the adjacent sub-pixels; by arranging the opening 23 in the second filter layer 21 and the lower color resistance portion 13 to overlap in the first direction D1, the transmittance of the light emitted from the lower color resistance portion 13 can be improved, thereby improving the display effect of the panel.

[0036] Figure 3 FIG. 1 is a schematic diagram of the structure of a display panel provided by an embodiment of the present disclosure. Figure 4 Shown Figure 3 A top view of the first filter layer in FIG. Figure 5 Shown Figure 3 For a top view of the second filter layer, please refer to Figures 1 to 5 The present disclosure provides a display panel 100, wherein the upper color resist portion 22 comprises a first upper color resist 221 and a second upper color resist 222 connected along a second direction D2, the opening 23 provided in the first upper color resist 221 is a first opening 231, the opening 23 provided in the second upper color resist 222 is a second opening 232, and the second direction D2 is parallel to the plane where the display panel 100 is located;

[0037] The lower color resist portion 13 includes a first lower color resist 131 and a second lower color resist 132 of different colors. Along the first direction D1, the first lower color resist 131 overlaps with the first opening 231, the second lower color resist 132 overlaps with the second opening 232, and the color of the first upper color resist 221 is the same as the color of the first lower color resist 131, and the color of the second upper color resist 222 is the same as the color of the second lower color resist 132. The color resist may be a red color resist, a green color resist, or a blue color resist; in some embodiments, the first lower color resist 131 is a red color resist, and the first upper color resist 221 corresponding to the first lower color resist 131 is a red color resist. When the second upper color resist 222 is a green color resist, the second lower color resist 132 corresponding to the second upper color resist 222 is also a green color resist. When the first upper color resist 221 is a red color resist, the second upper color resist 222 adjacent to the first upper color resist 221 may be a green color resist or a blue color resist. The red light emitted from the first lower color resist 131 passes through the first upper color resist 221 which is also a red color resist, and the red light emitted from the first lower color resist 131 is blocked by the second upper color resist 222 which is a green color resist; when the second upper color resist 222 is a blue color resist, the second lower color resist 132 corresponding to the second upper color resist 222 is also a blue color resist. Similarly, the red light emitted from the first lower color resist 131 is blocked by the second upper color resist 222 which is a blue color resist.

[0038] In some embodiments, the first lower color resist 131 is a green color resist, then the first upper color resist 221 corresponding to the first lower color resist 131 is a green color resist, and the second upper color resist 222 adjacent to the first upper color resist 221 may be a red color resist or a blue color resist. When the second upper color resist 222 is a red color resist, the second lower color resist 132 corresponding to the second upper color resist 222 is also a red color resist. When the second upper color resist 222 is a blue color resist, the second lower color resist 132 corresponding to the second upper color resist 222 is also a blue color resist. In some embodiments, the first lower color resist 131 is a blue color resist, then the first upper color resist 221 corresponding to the first lower color resist 131 is a blue color resist, and the second upper color resist 222 adjacent to the first upper color resist 221 may be a red color resist or a green color resist. When the second upper color resist 222 is a red color resist, the second lower color resist 132 corresponding to the second upper color resist 222 is also a red color resist. When the second upper color resist 222 is a green color resist, the second lower color resist 132 corresponding to the second upper color resist 222 is also a green color resist.

[0039] Please combine Figure 3 and Figure 5The second filter layer 21 on the second substrate 20 includes a plurality of upper color resist portions 22. Along a direction parallel to the plane where the display panel 100 is located, 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, 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, along the second direction D2, 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. Figure 5 The example only takes the first opening 231 set in the first upper color resist 221 and the second opening 232 set in the second upper color resist 222 as the same size, which does not represent the size relationship of the opening of R (red color resist), the opening of B (blue color resist) and the opening of G (green color resist). In other embodiments, the sizes of the first opening 231 and the second opening 232 can be differentiated according to the color of the color resist or the transmittance, which shall be based on actual needs.

[0040] Please combine 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. The first lower color resist 131 and the second lower color resist 132 have different colors. Figure 4 The light shielding portion 14 is only shown as a mesh structure. In other embodiments, the light shielding portion 14 can also be other structures, which are not limited in the present disclosure. Figure 4 The first filter layer 12 includes a shading portion 14 and a lower color resist portion 13. The lower color resist portion 13 is filled with color resists, and the color resists include red color resists, green color resists, and blue color resists. It should be noted that the sizes of the red color resists, green color resists, and blue color resists in the first filter layer 12 can be the same or different. Figure 4 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 resists of each color are arranged monochrome along the direction perpendicular to the second direction.

[0041] In an optional embodiment provided by the present disclosure, along a direction perpendicular to the plane where the display panel 100 is located, the first lower color block 131 in the first filter layer 12 overlaps with the first opening 231 in the second filter layer 21, and the second lower color block 132 in the first filter layer 12 overlaps with the second opening 232 in the second filter layer 21. The color of the first lower color block 131 is the same as the color of the first upper color block 221, and the color of the second lower color block 132 is the same as the color of the second upper color block 222. The light emitted from the second lower color block 132 is different from the light emitted from the first lower color block 131 to the first opening 231. If the light emitted from the second lower color block 132 enters the first opening 231, it will be mixed with the light in the first opening 231, resulting in color deviation of the light emitted from the first opening 231, affecting the display effect. The first upper color block 221 can block the light emitted from the second lower color block 132 from entering the first opening 231, thereby reducing color mixing and improving the display effect. The color of the first lower color block 131 is the same as the color of the first upper color block 221, and the light of the first lower color block 131 can be emitted through the first upper color block 221, which is beneficial to increase the light output of the panel at a wide viewing angle. By introducing the first upper color block 221, the light output at a wide viewing angle is increased and color mixing can be avoided; similarly, the light emitted from the first lower color block 131 is different from the light emitted from the second lower color block 132 to the second opening 232. If the light emitted from the first lower color block 131 enters the second opening 232, it will be mixed with the light in the second opening 232, causing the light emitted from the second opening 232 to have a color deviation, affecting the display effect. The second upper color block 222 can block the light emitted from the first lower color block 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. The light of the second lower color resist 132 can be emitted through the second upper color resist 222, which is beneficial to increase the light output of the panel at a large viewing angle. By introducing the second upper color resist 222, the light output at a large viewing angle is increased and color mixing can be avoided.

[0042] Figure 6 FIG. 1 is a schematic diagram of an outgoing light beam of a display panel provided by an embodiment of the present disclosure. Figure 7 FIG. 1 is another schematic diagram of an outgoing light beam of a display panel provided in an embodiment of the present disclosure. Figure 6As shown, when the first substrate 10 and the second substrate 20 are precisely aligned, the solid arrow in the figure is the light emitting direction of the display panel 100 at a front view angle, where the “front view angle” can be understood as the angle of observing the display panel 100 along the first direction D1 on one side of the light emitting surface of the display panel 100, and the dotted arrow in the figure is the light emitting direction of the display panel 100 at a side view angle, where the “side view angle” can be understood as the angle of observing the display panel in other directions intersecting with the first direction D1 on one side of the light emitting surface of the display panel 100. It can be seen from the figure that due to the presence of the second filter layer 21, light exceeding the range of the opening 23 can pass through the first upper color resist 221; Figure 7 As shown in the figure, when there is an alignment offset between the first substrate 10 and the second substrate 20, the solid arrow in the figure is the light emitting direction of the display panel 100 at a front viewing angle, and the dotted arrow in the figure is the light emitting direction of the display panel 100 at a side viewing angle. The inclined light emitted from the first lower color resist 131 can pass through the first upper color resist 221 and be emitted to the light emitting surface of the display panel 100, and the inclined light emitted from the first lower color resist 131 cannot pass through the second upper color resist 222. It can be seen from the figure that without adding a new process and reducing the aperture ratio loss, even if the first substrate 10 and the second substrate 20 are aligned, due to the existence of the second filter layer 21, the output light of the display panel 100 can be increased at a side viewing angle; that is, when the first upper color resist 221 is used as a filter structure of the first lower color resist 131, the alignment margin between the first substrate 10 and the second substrate 20 can be increased to reduce the aperture ratio loss. When the first upper color resist 221 is used as a filter structure of the second lower color resist 132, the aperture ratio loss can be reduced. When the second upper color resist 222 is used as the light filtering structure of the second lower color resist 132, the crosstalk between the adjacent sub-pixels 108 can be reduced. Similarly, when the second upper color resist 222 is used as the light blocking structure of the first lower color resist 131, the crosstalk between the adjacent sub-pixels 108 can be reduced. In this way, by setting the colors of the first upper color resist 221 and the first lower color resist 131 to be the same, and setting the colors of the second upper color resist 222 and the second lower color resist 132 to be the same, the first upper color resist 221 can be used as the light filtering structure of the first lower color resist 131 and the light blocking structure of the second lower color resist 132 at the same time, and the second upper color resist 222 can be used as the light filtering structure of the second lower color resist 132 and the light blocking structure of the first lower color resist 131 at the same time, which is beneficial to increase the alignment margin of the first substrate 10 and the second substrate 20, reduce the light crosstalk between the adjacent sub-pixels 108, and improve the display effect.

[0043] Please refer to Figures 3 to 7 , the present disclosure provides a display panel 100 , wherein along the second direction D2 , the light shielding portion 14 located between the first lower color resist 131 and the second lower color resist 132 is a first light shielding portion 141 ;

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

[0045] Specifically, along a direction parallel to the plane where the display panel 100 is located, the first light shielding portion 141 is located between the first lower color block 131 and the second lower color block 132, and along a direction perpendicular to the plane where 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 block 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 block 222 in the second filter layer 21 on the second substrate 20, that is, along the first direction D1, the first upper color block 221 and the second upper color block 222 are both located between the first lower color block 131 and the second lower color block 132. The shading portion 141 overlaps, the first upper color resist 221 is located above the first shading portion 141, and the second upper color resist 222 is located above the first shading portion 141. In this way, by arranging the first shading portion 141, the first upper color resist 221, and the second upper color resist 222 to overlap 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, and 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 beneficial to the passage of light when the upper color resist portion 22 is used as a filtering structure, improves the alignment margin of the first substrate 10 and the second substrate 20, and reduces the opening rate loss of the first substrate 10 and the second substrate 20.

[0046] Please continue to refer to Figure 3 The present disclosure provides a display panel 100, wherein along 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 the 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 opening 231 in the second direction D2.

[0047] Specifically, a first filter layer 12 is formed on the first substrate 10, and the first filter layer 12 includes a light shielding portion 14 and a lower color block portion 13. Along a direction parallel to the plane where the display panel 100 is located, the second light shielding portion 142 is located on a side of the first lower color block 131 away from the second lower color block 132, that is, the second light shielding portion 142 is adjacent to the first lower color block 131, and the first lower color block 131 is located between the second light shielding portion 142 and the first light shielding portion 141. Similarly, the second lower color block 132 is located between the first light shielding portion 141 and the second light shielding portion 142. The present disclosure only describes the first lower color block 131. 1. The relative positions of the second lower color block 132, the first light shielding portion 141, and the second light shielding portion 142 are limited, but their absolute positions are not limited; along the direction parallel to the plane where the display panel 100 is located, 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 opening 231. When the lower color block portion 13 is formed, it can overlap with the light shielding portion 14. Therefore, when 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 opening 231, it means that the first filter layer on the first substrate 10 The width of the lower color block portion 13 in the middle of 12 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, so that the alignment margin between the first substrate 10 and the second substrate 20 can be increased, and the opening rate loss can be reduced. However, at this time, the range of light emitted from the first light shielding portion 141 and the second light shielding portion 142 is greater than the range of light that can be accommodated by the first opening 231. Combined with the first upper color block 221 and the first lower color block 131 of the same color in the aforementioned embodiment, the second upper color block 222 and the second lower color block 132 of the same color are greater than the range of light that can be accommodated by the first opening 231. The light within the range is increased, and the second upper color resist 222 having a different color from the first upper color resist 221 serves as a light blocking structure to reduce the color mixing between adjacent sub-pixels 108 and improve the display effect. In this way, by setting the distance H1 between the first light shielding portion 141 and the second light shielding portion 142 to be greater than or equal to the width H2 of the first opening 231 in the second direction D2, the substrate alignment margin can be improved while combining the dual effects of filtering or blocking the first upper color resist 221 to increase the light emission range, reduce the light mixing between sub-pixels 108 of different colors, and improve the display effect.

[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 along a direction parallel to the display panel 100 .

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

[0050] Figure 8 FIG. 1 is a schematic diagram of a display panel structure provided by an embodiment of the present disclosure. Please refer to FIG. Figure 8 The present disclosure provides a display panel 100, wherein the light shielding portion 14 between the first lower color resist 131 and the second lower color resist 132 is a first light shielding portion 141, and a distance h2 between the first opening 231 and the second opening 232 is greater than or equal to a 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, on which a first filter layer 12 is formed, the first filter layer 12 includes a lower color block portion 13 and a light shielding portion 14, the lower color block portion 13 includes a first lower color block 131 and a second lower color block 132 of different colors, and along a direction parallel to the plane where the first substrate 10 is located, the light shielding portion 14 located between the first lower color block 131 and the second lower color block 132 is a first light shielding portion 141; the display panel 100 includes a second substrate 20 that is parallel to and opposite to the first substrate 10, on which a second filter layer 21 is formed, and the second filter layer 21 includes The upper color resist portion 22 and the opening 23, the upper color resist portion 22 includes a first upper color resist 221 and a second upper color resist 222 of different colors, 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, and along the direction parallel to the plane where the display panel 100 is located, 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, that is, in the second direction D2, the width of the upper color resist portion 22 located 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 upper color resist portion 22 is provided with an opening 23, and along the first direction D1, the projection of the upper color resist portion 22 on the second substrate 20 is annular, and the width of the upper color resist portion 22 can be the physical width of the annular portion.

[0052] Due to the limitation of the production process, the first substrate 10 and the second substrate 20 may be offset in alignment. 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 may 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 will not weaken the light emitted from the display panel 100. If the distance h2 between the first opening 231 and the second opening 232 is less than the distance h2 between the first light shielding portion 141 in the second direction D2, the first upper color resist 221 and the first lower color resist 131 may overlap in the first direction D1. With respect to the width h1 in the second direction D2, in the direction parallel to the plane where the display panel 100 is located, there is a portion of the first light shielding portion 141 between the first lower color resist 131 and the first upper color resist 221, and there is a portion of the first light shielding portion 141 between the second lower color resist 132 and the second upper color resist 222, which will visually present problems such as a black display screen and a discontinuous display. In this way, 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, visual problems such as a black state and a discontinuous display screen can be reduced, and the alignment margin of the first substrate 10 and the second substrate 20 can be increased, thereby improving the product yield.

[0053] Fig. 9 FIG. 1 is a schematic diagram of another display panel structure provided by an embodiment of the present disclosure, please refer to FIG. Fig. 9 The present disclosure provides a display panel 100 , wherein along a first direction D1 , a first upper color resist 221 and a second upper color resist 222 include an overlapping portion 223 .

[0054] Specifically, the display panel 100 includes a second substrate 20, on which a second filter layer 21 is formed, the second filter layer 21 includes an upper color resist portion 22, the upper color resist portion 22 is provided with an opening 23, the upper color resist portion 22 includes a first upper color resist 221 and a second upper color resist 222 connected to each other, 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. In an optional embodiment provided in the present disclosure, along a direction perpendicular to the plane where the display panel 100 is located, the first upper color resist 221 and the second upper color resist 222 include an overlapping portion 223, 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, and the distance between the first opening 231 and the second opening 232 is greater than or equal to the width of the first light shielding portion 141 in the second direction D2, that is, 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. The sum of the widths of the two upper color resists 222 in the second direction D2 is greater than or equal to the width of the first light shielding portion 141 in the second direction D2. Since the first upper color resist 221 and the second upper color resist 222 include the overlapping portion 223, the width range of the first upper color resist 221 and the second upper color resist 222 including the overlapping portion 223 can be set relatively flexibly relative to the first upper color resist 221 and the second upper color resist 222 not including the overlapping portion 223, thereby reducing the requirements for the actual production process. In this way, along the first direction D1, by setting the overlapping portion 223 on the first upper color resist 221 and the second upper color resist 222, the overlapping portion 223 can be used as a light shielding structure, and the light emitted from the first lower color resist 131 to the overlapping portion 223 cannot be emitted, and the light emitted from the second lower color resist 132 to the overlapping portion 223 cannot be emitted, which is equivalent to increasing the area of ​​the light shielding structure between adjacent sub-pixels, which is beneficial to reducing color mixing and color deviation.

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

[0056] Fig.10 FIG. 1 is a schematic diagram showing the relative width of the overlapped portion and the first upper color resist in a display panel provided by an embodiment of the present disclosure. Please refer to FIG. Fig.10 The present disclosure provides a display panel 100 , wherein a width L2 of the overlapping portion 223 in the second direction D2 is less than or equal to 1 / 2 of a width L1 of the first upper color resist 221 in the second direction D2 .

[0057] Specifically, along a direction perpendicular to the plane where the display panel 100 is located, the first upper color resist 221 and the second upper color resist 222 include an overlapping portion 223, and along the second direction D2, the width of the overlapping portion 223 is less than or equal to half of the width of the first upper color resist 221, wherein the width of the first upper color resist 221 in the second direction D2 refers to, along the second direction D2, in the same upper color resist portion 22, the farthest distance from one end of the first upper color resist 221 facing the first opening 231 to the connection between the first upper color resist 221 and the second upper color resist 222; in some embodiments, when the width of the first upper color resist 221 is equal to the width of the second upper color resist 222, the width L2 of the overlapping portion 223 in the upper color resist portion 22 is less than or equal to half of the width L2 of the first upper color resist 221 or the width of the second upper color resist 222, because the overlapping portion 223 is part of the first upper color resist 221 and part of the first upper color resist 221. The second upper color resist 222 overlaps in the first direction D1, and the overlapping portion 223 has two different color resists in the first direction D1, and the overlapping portion 223 only has a light blocking function but no light filtering function; when the width L2 of the overlapping portion 223 is greater than half of the width L1 of the first upper color resist 221, the overlapping portion 223 is too wide. Compared with the first lower color resist 131, the overlapping portion 223 and the second upper color resist 222 are both light blocking structures. If the light blocking range is too large, the light emitted from the first lower color resist 131 will be reduced, thereby affecting the display effect; in this way, the width L2 of the overlapping portion 223 in the second direction D2 is set to be less than or equal to half of the width L1 of the first upper color resist 221 in the second direction D2, so that the light blocking range is not too large as much as possible, thereby reducing the blocking of the emitted light while increasing the widths of the first upper color resist 221 and the second upper color resist 222 and reducing the process difficulty.

[0058] Please continue to refer to Fig.10 The present disclosure provides a display panel 100 , wherein the light shielding portion 14 between the first lower color resist 131 and the second lower color resist 132 is a first light shielding portion 141 , and a width L2 of the overlapping portion 223 is smaller than a width h1 of the first light shielding portion 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 resist portion 13 and a light shielding portion 14, the lower color resist portion 13 includes a first lower color resist 131 and a second lower color resist 132 of different colors, along a direction parallel to the plane where the second substrate 20 is located, the first light shielding portion 141 is located between the first lower color resist 131 and the second lower color resist 132, the width L2 of the overlapping portion 223 is less than the width h1 of the first light shielding portion 141, if the width L2 of the overlapping portion 223 is greater than or equal to the first If the width h1 of the shading portion 141 is less than that of the first shading portion 141, the light blocking range of the overlapping portion 223 is too large, and the light emitted from the first filter layer 12 is blocked by the overlapping portion 223 in a larger range, while the light emitted from the upper color blocking portion 22 has a narrower range, which affects the display effect. In this way, by setting the width L2 of the overlapping portion 223 in the second direction D2 to be smaller than the width h1 of the first shading portion 141 in the second direction D2, the light blocking range of the overlapping portion 223 as a light blocking structure can be reduced, the light emitted from the upper color blocking portion 22 can be increased, and the display defect caused by the overlapping portion 223 being too wide can be reduced.

[0060] Please continue to refer to Fig.10 The present disclosure provides a display panel 100, wherein a width L1 of a first upper color resist 221 in the second direction D2 is smaller than a width h1 of a first light shielding portion 141 in the second direction D2, and / or a width L3 of a second upper color resist 222 in the second direction D2 is smaller than a width h1 of a first light shielding portion 141 in the second direction D2.

[0061] Specifically, in an optional embodiment provided by the present disclosure, along the direction parallel to the plane where the display panel 100 is located, the width L1 of the first upper color resist 221 is smaller than the width h1 of the first light shielding portion 141; in another optional embodiment provided by the present disclosure, along the direction parallel to the plane where the display panel 100 is located, the width L3 of the second upper color resist 222 is smaller than the width h1 of the first light shielding portion 141; in yet another optional embodiment provided by the present disclosure, along the direction parallel to the plane where the display panel 100 is located, The width L1 of the first upper color resist 221 is smaller than the width h1 of the first light shielding portion 141, and the width L3 of the second upper color resist 222 is smaller than the width h1 of the first light shielding portion 141; that is, in the first direction D1, both the first upper color resist 221 and the second upper color resist 222 are located above the first light shielding portion 141. With respect to the first lower color resist 131, the first upper color resist 221 located 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. The second upper color block 222 above the first light shielding portion 141 and having a different color from the first lower color block 131 blocks the light emitted from the first lower color block 131 from passing through. If the width L1 of the first upper color block 221 is greater than or equal to the width h1 of the first light shielding portion 141, the range of the light emitted from the first upper color block 221 is too large, which may easily cause color mixing of light between adjacent sub-pixels 108. If the width L3 of the second upper color block 222 is greater than or equal to the width h1 of the first light shielding portion 141, the light emitted from the second upper color block 222 If the range is too large, it is easy to cause color mixing of light between adjacent sub-pixels 108. In this way, by setting the width L1 of the first upper color resist 221 in the second direction D2 to be smaller than the width h1 of the first light shielding portion 141 in the second direction D2, and / or setting the width L3 of the second upper color resist 222 in the second direction D2 to be smaller than the width h1 of the first light shielding portion 141 in the second direction D2, the color mixing of light between adjacent sub-pixels 108 can be reduced while making the range of the emitted light as large as possible, thereby improving the display effect.

Optionally, the array layer 11 also includes a driving chip 90, which is located on one side of the plane where the array layer 11 is located. The driving chip 90 provides data signals to the sub-pixel 108 through the data line 118; the first filter layer 12 is also formed on the side of the array layer 11 away from the first substrate 10, and is connected to the first substrate The second filter layer 21 is formed on the second substrate 20 which is parallel and relatively arranged on the board 10. The light emitted from the sub-pixel 108 in the array layer 11 is filtered and blocked by the first filter layer 12 and the second filter layer 21, and finally forms a display picture; in this way, by setting the array layer 11 including the sub-pixel 108, a driving voltage can be provided to the liquid crystal layer 30 when the display panel 100 is working normally, and combined with the filtering and blocking effects of the first filter layer 12 and the second filter layer 21, the normal display of the display panel 100 is finally achieved.

In the actual production process, the thickness of the lower color resist portion 13 in the first filter layer 12 on the first substrate 10 and the thickness of the second substrate 20 can be adjusted according to the requirements of color coordinates, color gamut, etc. The thickness of the upper color resist portion 22 in the upper second filter layer 21 is adjusted to match. For example, the lower color resist portion 13 in the first filter layer 12 of the first substrate 10 can be made into segmented thickness, that is, the thickness of the central portion 133 and the edge portion 134 of the lower color resist portion 13 are different, so as to match the upper color resist portion 22 in the second filter layer 21 on the second substrate 20, and achieve the required optical specifications and effects; in this way, by setting the thickness of the edge portion 134 and the central portion 133 of the lower color resist portion 13 to be different, the segmented thickness of the lower color resist portion 13 can be flexibly adjusted according to optical requirements such as color coordinates and color gamut, so as to match the upper color resist portion 22 and achieve the required optical effect.
