Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a display panel and display device. Background Technology

[0002] With the continuous development of LCD panels, the resolution of products is getting higher and higher, which leads to an increase in pixels. This causes a series of problems. For example, when LCD panels are subjected to certain pressure tests or drop tests, the panel bends under pressure, causing the spacers on the panel to shift and easily scratch the alignment film. When the pressure is removed, the panel recovers and the spacers return to their original positions, but the scratches on the alignment film are irreversible. During the display process, light leakage may occur at the scratched areas, which can easily lead to bright spots, snowflakes, and other uneven brightness problems, affecting the quality of the product.

[0003] Related technologies improve display quality by increasing the width of the black matrix area. This allows the black matrix area to block scratches on the alignment film during pressure or drop tests, even if the spacer shifts and damages the film. However, this approach reduces the aperture ratio of the display panel. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a display panel that, while ensuring the aperture ratio, reduces the display unevenness caused by light leakage, thereby improving the display effect.

[0005] This invention also aims to provide a display device having the above-mentioned display panel.

[0006] A display panel according to an embodiment of the first aspect of the present invention includes a color filter substrate and an array substrate disposed opposite to each other.

[0007] The color filter substrate has a plurality of first spacers on one side facing the array substrate. The first spacers are located between the openings of adjacent sub-pixels of the same color on the color filter substrate, and the first spacers are spaced apart from the array substrate.

[0008] The array substrate has a plurality of protrusions on the side facing the color filter substrate. At least a portion of the protrusions in the orthographic projection of the color filter substrate are located between the openings of adjacent different color sub-pixels of the color filter substrate, and are located on the path of the first spacer moving from the end away from the color filter substrate to the area of ​​the sub-pixel opening.

[0009] According to some embodiments of the present invention, the protrusion on the orthographic projection of the color filter substrate and the end of the first spacer away from the color filter substrate are spaced apart from the orthographic projection of the color filter substrate.

[0010] According to some embodiments of the present invention, the first spacer has at least one protrusion on each of its opposite sides facing the opening of an adjacent sub-pixel of the same color.

[0011] According to some embodiments of the present invention, the array substrate includes a gate layer, the gate layer includes a gate trace region and a blocking pad region, and the blocking pad region is located between the openings of adjacent different color sub-pixels in the orthographic projection of the color filter substrate to form the protrusion.

[0012] According to some embodiments of the present invention, the length of the blocking pad area along the first direction is 26μm-30μm, and the first direction is the extension direction of the area between the openings of adjacent sub-pixels of different colors.

[0013] According to some embodiments of the present invention, the protrusion on the orthographic projection of the color filter substrate and the end of the first spacer away from the color filter substrate intersect on the orthographic projection of the color filter substrate, and the first spacer is spaced apart from the protrusion along the direction from the color filter substrate to the array substrate.

[0014] According to some embodiments of the present invention, the color filter substrate is further provided with a plurality of second spacers on the side facing the array substrate, and the second spacers are located between the openings of adjacent sub-pixels of the same color on the color filter substrate;

[0015] The array substrate has a plurality of pads on the side facing the color filter substrate. The orthographic projection of the pads onto the color filter substrate is located between the openings of adjacent different color sub-pixels on the color filter substrate. The end of the second spacer away from the color filter substrate crosses and abuts against the pads.

[0016] According to some embodiments of the present invention, the length of the first spacer along the second direction is 26μm-40μm and the width is 12μm-26μm, and the second direction is the extension direction between the openings of adjacent sub-pixels of the same color;

[0017] The protrusion has a length of 26μm-40μm and a width of 12μm-26μm along the first direction, where the first direction is the extension direction of the region between the openings of adjacent sub-pixels of different colors.

[0018] The second spacer has a length of 26μm-40μm and a width of 12μm-26μm along the second direction;

[0019] The length of the pad along the first direction is 26μm-40μm, and the width is 12μm-26μm.

[0020] According to some embodiments of the present invention, the color filter substrate includes a black matrix and the sub-pixel openings defined by the black matrix. Along the direction from the color filter substrate to the array substrate, the height of the black matrix is ​​greater than the sum of the maximum deformation of the protrusion and the maximum deformation of the first spacer.

[0021] This application provides a display panel in which a first spacer is provided on the side of the color filter substrate facing the array substrate. When the display panel is subjected to pressure, the first spacer supports both the color filter substrate and the array substrate. Multiple protrusions are present on the side of the array substrate facing the color filter substrate. At least a portion of the protrusions, projected onto the orthographic projection of the color filter substrate, is located between the openings of adjacent sub-pixels of different colors on the color filter substrate, and lies on the path of the end of the first spacer away from the color filter substrate moving towards the sub-pixel opening. Thus, when the display panel is subjected to pressure, the end of the first spacer away from the color filter substrate is obstructed from moving towards the sub-pixel opening, making it difficult to move to the sub-pixel opening area or to slide relative to it. This reduces the risk of scratching the alignment film on the array substrate projected onto the sub-pixel opening area, and reduces the risk of light leakage during sub-pixel display after the pressure is removed. This improves the display effect of the panel while maintaining the aperture ratio of the display panel.

[0022] The display device according to a second aspect of the present invention includes the display panel in the above embodiment.

[0023] The display device according to the present utility model, by adopting the display panel in the above embodiment, reduces the display unevenness caused by light leakage while ensuring the aperture ratio, thereby improving the display effect and display quality.

[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0037] A display panel, such as a liquid crystal display (LCD) panel, is a type of display that uses liquid crystal as its material. Under the influence of an electric field, the liquid crystal molecules undergo a change in alignment, thereby affecting the intensity of the incident light beam passing through the liquid crystal. This change in light intensity is further manifested as a change in brightness through the action of a polarizer. Therefore, by controlling the electric field of the liquid crystal, changes in light brightness can be achieved, thus achieving the purpose of information display.

[0038] A liquid crystal display panel generally includes a color filter substrate and an array substrate, as well as a support spacer between the color filter substrate and the array substrate. The spacer supports the liquid crystal that can be filled with liquid crystal.

[0039] The color filter substrate includes a glass substrate and various color filter layers, such as red, green, and blue, disposed on the glass substrate. The filter layers are patterned using photolithography to create fine patterns that display pixels of various colors. Different color filter layers are separated by light-shielding materials.

[0040] The array substrate supports the pixel electrode layer and the transistor (TFT) switch. The array substrate is typically made of insulating materials such as glass or plastic, and contains one or more conductive metal layers and insulating layers. The conductive metal layers form the data lines and scan lines, while the insulating layers isolate the electrical contacts between different conductive layers. The transistors on the array substrate act as switching elements, driving each pixel unit. When a scan signal reaches a transistor, the transistor turns on, allowing the drive signal to pass through and charge the pixel electrode.

[0041] With the continuous development of LCD panels, the resolution of products is getting higher and higher, which leads to an increase in pixels. This causes a series of problems. For example, when LCD panels are subjected to certain pressure tests or drop tests, the panel bends under pressure, causing the spacers on the panel to shift and easily scratch the alignment film. When the pressure is removed, the panel recovers and the spacers return to their original positions, but the scratches on the alignment film are irreversible. During the display process, light leakage may occur at the scratched areas, which can easily lead to bright spots, snowflakes, and other uneven brightness problems, affecting the quality of the product.

[0042] Related techniques increase the width of the black matrix region, referencing Figure 1 This design ensures that during pressure or drop tests, even if the spacer shifts and scratches the alignment film, the black matrix area can still block the scratched area. Thus, even if light leaks from the scratched area, it will be blocked by the black matrix and not easily displayed, reducing light leakage and improving display quality. However, increasing the width of the black matrix area reduces the pixel aperture area, lowering the aperture ratio of the display panel and affecting display performance.

[0043] Based on this, the present invention proposes a display panel 100, which restricts the first spacer 14 by setting protrusions 25 on the array substrate 20, so that the first spacer 14 is not easy to slide relative to the pixel opening, thereby not easily scratching the alignment film. This ensures the aperture ratio of the display panel 100, while reducing the possibility of light leakage and the display unevenness caused by light leakage, thus improving the display effect.

[0044] Figures 2-6This is a schematic diagram of the structure of the display panel 100 according to an embodiment of the present utility model. (Refer to...) Figures 2-6 The display panel 100 includes a color filter substrate 10 and an array substrate 20 disposed opposite to each other.

[0045] The color filter substrate 10 is used to provide color, regulate light, and protect the internal liquid crystal layer. The color filter substrate 10 generally includes a glass substrate and a black matrix 12a disposed on the glass substrate. Openings are etched in the black matrix 12a to form sub-pixel openings 12b, and a color resist layer is disposed in the sub-pixel openings 12b to form sub-pixel dots.

[0046] The array substrate 20 is used to support the pixel electrode layer and the transistor (TFT) switch. Generally, the projection of the metal conductive layer and the transistor switch on the array substrate 20 onto the color filter substrate 10 is located within the black matrix 12a so as to be blocked by the black matrix 12a.

[0047] The color filter substrate 10 has a plurality of first spacers 14 on the side facing the array substrate 20. The plurality of first spacers 14 can be spaced apart on the color filter substrate 10. Specifically, the plurality of first spacers 14 can be spaced apart on the color filter substrate 10 at the same spacing; or, the plurality of first spacers 14 can be spaced apart on the color filter substrate 10 at different spacings; or, the plurality of first spacers 14 form a plurality of first spacer units, each first spacer unit including a plurality of first spacers 14. The plurality of first spacers 14 in each first spacer unit can be spaced apart at the same or different spacings, and the plurality of first spacer units can also be spaced apart at the same or different spacings.

[0048] The first spacer 14 is located between the openings 12b of adjacent sub-pixels of the same color on the color filter substrate 10. That is, the first spacer 14 is disposed on the black matrix 12a, which does not easily affect the display of the sub-pixels.

[0049] Generally, adjacent sub-pixel openings 12b are separated by a black matrix 12a. The distance between adjacent sub-pixel openings 12b of the same color is relatively large, while the distance between adjacent sub-pixel openings 12b of different colors is relatively small. Therefore, the first spacer 14 is disposed between adjacent sub-pixel openings 12b of the same color in the color filter substrate 10, so that the projection of the first spacer 14 on the black matrix 12a can be larger, so as to provide better support.

[0050] The first spacer 14 is spaced apart from the array substrate 20, so that when the display panel 100 is subjected to pressure, the end of the first spacer 14 away from the color filter substrate 10 can be supported on the array substrate 20. That is, the first spacer 14 serves as an auxiliary spacer between the color filter substrate 10 and the array substrate 20.

[0051] It is understood that the color filter substrate 10 is provided with a second spacer 15 on the side facing the array substrate 20, which is secondly supported on the array substrate 20. That is, the second spacer 15 serves as the main spacer between the color filter substrate 10 and the array substrate 20, and is used to support the color filter substrate 10 and the array substrate 20.

[0052] The array substrate 20 has a plurality of protrusions 25 on the side facing the color filter substrate 10. It is understood that the orthogonal projection of the protrusions 25 onto the color filter substrate 10 is located within the black matrix 12a, so as to avoid affecting the display of sub-pixels.

[0053] At least a portion of the orthographic projection of the protrusion 25 onto the color filter substrate 10 is located between adjacent different color sub-pixel openings 12b of the color filter substrate 10. That is, the orthographic projection of the protrusion 25 onto the color filter substrate 10 can be entirely located between adjacent different color sub-pixel openings 12b of the color filter substrate 10, or it can be partially located between adjacent different color sub-pixel openings 12b, and partially extend to adjacent identical extended sub-pixel openings 12b.

[0054] At least a portion of the orthographic projection of the protrusion 25 onto the color filter substrate 10 lies on the path of the first spacer 14 moving away from the color filter substrate 10 to the area of ​​the sub-pixel opening 12b. Thus, when the display panel 100 is subjected to pressure, the first spacer 14, away from the color filter substrate 10, is obstructed by the protrusion 25 during its movement toward the area of ​​the sub-pixel opening 12b, making it difficult to move to the area of ​​the sub-pixel opening 12b. Or, even if it moves to the area of ​​the sub-pixel opening 12b, it is not easy to slide relative to the area of ​​the sub-pixel opening 12b due to the support of the protrusion 25. This makes it less likely to scratch the alignment film on the array substrate 20 whose orthographic projection is located in the area of ​​the sub-pixel opening 12b, and less likely to cause light leakage during the display of sub-pixels after the pressure is removed. This improves the display effect of the panel while ensuring the aperture ratio of the display panel 100.

[0055] Therefore, referring to Figures 2-6 , refer to Figures 2-6According to the display panel 100 of this utility model, by providing a first spacer 14 on the side of the color filter substrate 10 facing the array substrate 20, the first spacer 14 can support the color filter substrate 10 and the array substrate 20 when the display panel 100 is subjected to pressure. On the side of the array substrate 20 facing the color filter substrate 10, there are multiple protrusions 25. At least a portion of the protrusions 25 projected onto the color filter substrate 10 is located between adjacent different color sub-pixel openings 12b of the color filter substrate 10, and is located on the path of the first spacer 14 moving away from the color filter substrate 10 to the area of ​​the sub-pixel opening 12b. In this way, when the display panel 100 is subjected to pressure, the first spacer 14, away from the color filter substrate 10, is hindered by the protrusions 25 during its movement towards the area of ​​the sub-pixel opening 12b, making it difficult to move to the area of ​​the sub-pixel opening 12b, or to slide relative to the area of ​​the sub-pixel opening 12b. This makes it less likely to scratch the alignment film on the array substrate 20 projected onto the area of ​​the sub-pixel opening 12b, and less likely to cause light leakage during the display of sub-pixel dots after the pressure is removed. This improves the display effect of the panel while ensuring the aperture ratio of the display panel 100.

[0056] The instruction manual indicates that the color filter substrate 10 includes a color filter glass layer 11, a pixel layer 12, a color filter alignment film layer 13, etc.

[0057] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 The protrusion 25 is positioned at an angle to the orthographic projection of the color filter substrate 10 and the end of the first spacer 14 away from the color filter substrate 10 is positioned at an angle to the orthographic projection of the color filter substrate 10. That is, when the display panel 100 is subjected to pressure, the end of the first spacer 14 away from the color filter substrate 10 will not directly abut against the upper surface of the protrusion 25. Instead, during the process of moving toward the area on the array substrate 20 where the orthographic projection is located in the sub-pixel opening 12b, it is blocked by the protrusion 25 and is not easy to move to the area on the array substrate 20 where the orthographic projection is located in the sub-pixel opening 12b. Therefore, it is not easy to slide relative to this area, and thus it is not easy to scratch the alignment film in this area.

[0058] Specifically, the orthographic projection of the protrusion 25 onto the color filter substrate 10 can be completely located between adjacent openings 12b of different colors, or it can be partially located between adjacent openings 12b of different colors, for example, it can also be partially located between adjacent openings 12b of the same color.

[0059] When the orthographic projection of the protrusion 25 onto the color filter substrate 10 is completely located between adjacent sub-pixel openings 12b of different colors, the edge of the orthographic projection of the protrusion 25 onto the color filter substrate 10 facing the first spacer 14 is flush with the edge of the adjacent sub-pixel opening 12b facing the first spacer 14. If the distance from the edge of the adjacent sub-pixel opening 12b facing the first spacer 14 to the first spacer 14 is different, then the edge of the orthographic projection of the protrusion 25 onto the color filter substrate 10 facing the first spacer 14 is flush with the edge of the sub-pixel opening 12b closer to the first spacer 14.

[0060] When the orthographic projection of the protrusion 25 onto the color filter substrate 10 is located between adjacent openings 12b of different colors, that is, when the orthographic projection of the protrusion 25 onto the color filter substrate 10 is also located between adjacent openings 12b of the same color, the length of the portion of the protrusion 25 located between adjacent openings 12b of the same color can be one-half, one-third, one-fifth, or the same as the distance between the first spacer 14 and the sub-pixel opening 12b.

[0061] In some embodiments of this utility model, reference is made to Figure 3 The first spacer 14 has at least one protrusion 25 on each of its opposite sides facing the opening 12b of the adjacent sub-pixel of the same color.

[0062] On either side of the first spacer 14 facing the adjacent sub-pixel opening 12b of the same color, there is at least one protrusion 25. In this way, no matter which side the first spacer 14 moves towards, it will be blocked by the protrusion 25. The first spacer 14 will not damage the sub-pixel openings 12b on both sides, thus further ensuring the display effect.

[0063] Specifically, the first spacer 14 may correspond to the same number of protrusions 25 on opposite sides of the opening 12b of the adjacent sub-pixel of the same color, for example, one or more protrusions 25 on each side; or it may correspond to different numbers of protrusions 25, for example, one protrusion 25 on one side and two or more protrusions 25 on the other side.

[0064] The orthographic projections of the protrusions 25 on opposite sides of the first spacer 14 facing the adjacent same-color sub-pixel opening 12b can all be completely located between the adjacent different-color sub-pixel openings 12b, or they can all be partially located between the adjacent different-color sub-pixel openings 12b, for example, some are also partially located between the adjacent same-color sub-pixel openings 12b. Alternatively, one of the orthographic projections of the first spacer 14 on opposite sides of the protrusions 25 facing the adjacent same-color sub-pixel opening 12b can be completely located between the adjacent different-color sub-pixel openings 12b, and the other can be partially located between the adjacent different-color sub-pixel openings 12b.

[0065] In some embodiments of this utility model, reference is made to Figure 2 The array substrate 20 includes a gate layer 22, which includes a gate trace region 221 and a blocking pad region 222. The orthogonal projection of the blocking pad region 222 onto the color filter substrate 10 is located between adjacent openings 12b of different color sub-pixels to form a protrusion 25.

[0066] By providing a blocking pad 26 region 222 in the gate layer 22, and the orthogonal projection of the blocking pad 26 region 222 in the color filter substrate 10 is located between the openings 12b of adjacent different color sub-pixels, the blocking pad 26 region 222 forms a protrusion 25 on the array substrate 20, which serves to restrict the first spacer 14.

[0067] By setting a blocking pad 26 region 222 in the gate layer 22, the gate layer 22 with the orthogonal projection of the color filter substrate 10 located between the openings 12b of adjacent different color sub-pixels can be retained during processing to form the blocking pad 26 region 222. Subsequently, each layer of the gate layer 22 facing the color filter substrate 10 is set in a conformal manner, so that the blocking pad 26 region 222 forms a protrusion 25 on the surface of the array substrate 20. There is no need to specially process the protrusion 25, which is convenient for processing and production, and the processing difficulty is low.

[0068] The instruction manual indicates that the array substrate 20 includes an array glass layer 21, a gate layer 22, a source / drain layer 23, an array alignment film layer 24, etc.

[0069] In some embodiments, protrusions 25 may also be provided on other layers of the array substrate 20. For example, protrusions 25 may be provided on the source / drain layer 23 of the array substrate 20, and then each layer of the source / drain layer 23 on the side facing the color filter substrate 10 may be provided in a conformal manner. Protrusions 25 may also be provided on the surface of the array substrate 20 facing the color filter substrate 10. For example, they may be metal protrusions 25, etc., as long as protrusions 25 can be formed.

[0070] In some embodiments of this utility model, reference is made to Figure 3The length of the blocking pad 26 region 222 along the first direction is 26μm-30μm, and the first direction is the extension direction of the region between adjacent sub-pixel openings 12b of different colors.

[0071] It should be noted that the extension direction of the region between adjacent sub-pixel openings 12b of different colors can be understood as the direction in which the region between adjacent sub-pixel openings 12b of different colors extends toward the region of adjacent sub-pixel openings 12b of the same color.

[0072] The length of the blocking pad 26 region 222 along the first direction is 26μm-30μm. Specifically, the length of the blocking pad 26 region 222 along the first direction can be 26μm, 28μm, 29μm, 30μm, etc.

[0073] It is understandable that the width of the blocking pad 26 area 222 along the direction from one to the other of the adjacent different color sub-pixel openings 12b can be the same as the distance between the adjacent different color sub-pixel openings 12b, or it can be slightly smaller than the distance between the adjacent different color sub-pixel openings 12b.

[0074] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 The projection of the protrusion 25 onto the color filter substrate 10 and the end of the first spacer 14 away from the color filter substrate 10 onto the projection of the color filter substrate 10 intersect, and the first spacer 14 and the protrusion 25 are spaced apart along the direction from the color filter substrate 10 to the array substrate 20.

[0075] The projection of the protrusion 25 onto the color filter substrate 10 and the projection of the end of the first spacer 14 away from the color filter substrate 10 onto the color filter substrate 10 intersect, that is, the projection of the protrusion 25 onto the color filter substrate 10 and the projection of the end of the first spacer 14 away from the color filter substrate 10 onto the color filter substrate 10 have an overlapping area.

[0076] Since the first spacer 14 and the protrusion 25 are spaced apart along the direction from the color filter substrate 10 to the array substrate 20, when the display panel 100 is subjected to pressure, the first spacer 14 and the protrusion 25 are squeezed together. Since the first spacer 14 is not squeezed to the array substrate 20, the compression of the first spacer 14 is greater than the compression of the protrusion to the array substrate 20. Thus, the friction between the first spacer 14 and the protrusion 25 is greater, and relative movement is not easy to occur. This restricts the first spacer 14 from moving to the area on the array substrate 20 where its orthographic projection is located in the sub-pixel opening 12b. Even if the first spacer 14 moves to the area on the array substrate 20 where its orthographic projection is located in the sub-pixel opening 12b under greater pressure, the protrusion 25 raises the first spacer 14, and the first spacer 14 is not easy to come into contact with or slide against the area on the array substrate 20 where its orthographic projection is located in the sub-pixel opening 12b. This makes it less likely to scratch the alignment film in that area.

[0077] It is understood that, along the first direction, the lengths of the orthographic projection of the protrusion 25 onto the color filter substrate 10 and the lengths of the first spacer 14 at the end away from the color filter substrate 10, which overlap on both sides of the orthographic projection onto the color filter substrate 10, can be the same or different. Preferably, the lengths of the protrusion 25 onto the color filter substrate 10 and the lengths of the first spacer 14 at the end away from the color filter substrate 10, which overlap on both sides of the orthographic projection onto the color filter substrate 10, are the same. In this way, the first spacer 14 has the same limiting effect regardless of which side the sub-pixel opening 12b moves towards.

[0078] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 The color filter substrate 10 is provided with a plurality of second spacers 15 on the side facing the array substrate 20. The second spacers 15 are located between the openings 12b of adjacent sub-pixels of the same color on the color filter substrate 10. The array substrate 20 has a plurality of pads 26 on the side facing the color filter substrate 10. The orthographic projection of the pads 26 onto the color filter substrate 10 is located between the openings 12b of adjacent sub-pixels of different colors on the color filter substrate 10. The end of the second spacer 15 away from the color filter substrate 10 crosses and abuts against the pad 26.

[0079] It should be noted that the second spacer 15 is the main spacer and is located in the black matrix 12a area. The second spacer 15 can be staggered with the first spacer 14. For example, multiple first spacers 14 can be set between two adjacent second spacers 15.

[0080] As is well known, the projection of the second spacer 15 onto the color filter substrate 10 is generally circular. In this application, the projection of the first spacer 14 onto the color filter substrate 10 is elongated, and its width is greater than the diameter of the second spacer 15, increasing the contact area with the array substrate 20 and thus increasing the friction with the array substrate 20. While providing protrusions 25 whose projections intersect with the first spacer 14 can reduce the distance between adjacent sub-pixels of different colors to increase the aperture ratio, the second spacer 15 may scratch the alignment film of the array substrate 20.

[0081] This application uses pads 26 that cross-abut against the second spacer 15 to prevent the second spacer 15 from sliding relative to the alignment film of the array substrate 20. This reduces the distance between adjacent sub-pixels of different colors, increases the aperture ratio, and ensures the display effect of the display panel 100.

[0082] In some embodiments of this utility model, reference is made to Figure 5 The first spacer 14 has a length of 26μm-40μm and a width of 12μm-26μm along the second direction, which is the extension direction between adjacent sub-pixel openings 12b of the same color; the protrusion 25 has a length of 26μm-40μm and a width of 12μm-26μm along the first direction, which is the extension direction between adjacent sub-pixel openings 12b of different colors; the second spacer 15 has a length of 26μm-40μm and a width of 12μm-26μm along the second direction; and the pad 26 has a length of 26μm-40μm and a width of 12μm-26μm along the first direction.

[0083] The length of the first spacer 14 along the second direction is set to 26μm-40μm, and the width is set to 12μm-26μm. The length of the protrusion 25 along the first direction is set to 26μm-40μm, and the width is set to 12μm-26μm. The length of the second spacer 15 along the second direction is set to 26μm-40μm, and the width is set to 12μm-26μm. The length of the pad 26 along the first direction is set to 26μm-40μm, and the width is set to 12μm-26μm. In this way, the distance between the openings 12b of adjacent sub-pixels of the same color can be reduced, thereby increasing the aperture ratio of the display panel 100.

[0084] It should be noted that in the prior art, the distance between the second spacer 15 and the adjacent opening 12b of the same color sub-pixel is relatively large. Even if the end of the second spacer 15 away from the color filter substrate 10 moves, the scratched alignment film area will be blocked by the black matrix 12a on the color filter substrate 10, making light leakage less likely. However, when the width of the first spacer 14 along the second direction is set to 12μm-26μm, the distance between the openings 12b of the adjacent same color sub-pixel becomes smaller. Therefore, if the end of the second spacer 15 away from the color filter substrate 10 moves, the scratched alignment film area is less likely to be blocked by the black matrix 12a on the color filter substrate 10, making light leakage more likely. Therefore, the solution in this application sets the width of the second spacer 15 along the second direction to 12μm-26μm as well, and provides a corresponding pad 26 to the second spacer 15, increasing the friction between the second spacer 15 and the pad 26, making the second spacer 15 less likely to move. Furthermore, the lengths of the first spacer 14, the second spacer 15, the protrusion 25, and the pad 26 are set to 26μm-40μm to restrict movement within this length range.

[0085] Specifically, the length of the first spacer 14 along the second direction can be 26μm, 27μm, 29μm, 32μm, 33μm, 35μm, 37μm, 38μm, or 40μm, and the width can be 12μm, 13μm, 15μm, 16μm, 18μm, 20μm, 22μm, 24μm, or 26μm;

[0086] The length of the protrusion 25 along the first direction can be 26μm, 27μm, 29μm, 32μm, 33μm, 35μm, 37μm, 38μm, or 40μm, and the width can be 12μm, 13μm, 15μm, 16μm, 18μm, 20μm, 22μm, 24μm, or 26μm;

[0087] The length of the second spacer 15 along the second direction can be 26μm, 27μm, 29μm, 32μm, 33μm, 35μm, 37μm, 38μm, or 40μm, and the width can be 12μm, 13μm, 15μm, 16μm, 18μm, 20μm, 22μm, 24μm, or 26μm;

[0088] The length of the pad 26 along the first direction can be 26μm, 27μm, 29μm, 32μm, 33μm, 35μm, 37μm, 38μm, or 40μm, and the width can be 12μm, 13μm, 15μm, 16μm, 18μm, 20μm, 22μm, 24μm, or 26μm.

[0089] In some embodiments of this utility model, reference is made to Figure 6The color filter substrate 10 includes a black matrix 12a and a sub-pixel opening 12b defined by the black matrix 12a. Along the direction from the color filter substrate 10 to the array substrate 20, the height of the black matrix 12a is greater than the sum of the maximum deformation of the protrusion 25 and the maximum deformation of the first spacer 14.

[0090] By setting the height of the black matrix 12a to be greater than the sum of the maximum deformation of the protrusion 25 and the maximum deformation of the first spacer 14, even if the first spacer 14 slides relative to the protrusion 25 and the end of the first spacer 14 away from the color filter substrate 10 moves to the orthographic projection area of ​​the sub-pixel opening 12b on the array substrate 20, the first spacer 14 is spaced apart from the alignment film of the array substrate 20. Therefore, it is not easy for the first spacer 14 to come into contact with and slide against the alignment film, thereby making it less likely to scratch the alignment film.

[0091] It should be noted that, along the direction from the color filter substrate 10 to the array substrate 20, the difference between the height of the region between adjacent color sub-pixel openings 12b and the height of the sub-pixel opening 12b region is the height of the black matrix 12a.

[0092] In some embodiments, refer to Figure 6 Along the direction from the color filter substrate 10 to the array substrate 20, the height d of the black matrix 12a is 1.15μm-1.5μm. Specifically, the height of the black matrix 12a can be 1.15μm, 1.20μm, 1.22μm, 1.30μm, 1.32μm, 1.37μm, 1.42μm, 1.47μm, or 1.5μm.
