AI Technical Summary
In the prior art, excessive distance between adjacent color filter sections can cause the light-shielding layer to break. Light emitted from the sub-pixel diffracts at the break in the light-shielding layer, resulting in color separation. Furthermore, particles generated after the light-shielding layer breaks fall at the positions relative to the openings in the color filter section and the light-shielding layer, causing black spot defects when the display substrate is displayed.
At least one color filter portion is provided in the color filter layer, including a protrusion connected to the main body portion. The protrusion portion is located between the main bodies of two adjacent color filter portions, thereby reducing the gap between adjacent color filter portions, and a light-shielding layer is provided on the side of the color filter layer away from the substrate.
It effectively reduces the gap between adjacent color filters, avoids light-shielding layer breakage, improves color separation, enhances the dark state effect and light extraction efficiency of the display substrate, and reduces ambient light reflection and light loss.

[0055] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other. When the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0056] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture; if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0057] This application provides a display substrate. As shown in FIG1, the display substrate includes a substrate 10, a light-emitting layer 20, a color filter layer 40, and a light-shielding layer 50. The light-emitting layer 20 is located on the substrate 10 and includes a plurality of spaced sub-pixels 21. The color filter layer 40 is located on the side of the light-emitting layer 20 away from the substrate 10 and includes a plurality of color filter portions 41. The light-shielding layer 50 is at least partially located on the side of the color filter layer 40 away from the substrate 10; the light-shielding layer 50 has a plurality of openings 51, and the orthographic projection of each opening 51 on the substrate 10 falls within the orthographic projection of one of the color filter portions 41 on the substrate 10. As shown in FIGS. 2 to 8, each color filter portion 41 includes a main body portion 411, and at least one color filter portion 41 includes a protrusion 412 connected to the main body portion 411, and each protrusion 412 is located between the main bodies 411 of two adjacent color filter portions 41.
[0058] The display substrate provided in this application embodiment includes at least one color filter portion 41 in the color filter layer 40, which includes a protrusion 412 connected to the main body portion 411. The protrusion 412 is located between the main bodies 411 of two adjacent color filter portions 41. This protrusion 412 reduces the gap between adjacent color filter portions 41, thereby improving the situation where the light-shielding layer 50 formed on the color filter portion 41 breaks due to excessive distance between adjacent color filter portions 41, causing diffraction of light emitted by the sub-pixel 21 at the break in the light-shielding layer 50, resulting in color separation. The problem is that particles generated after the light-shielding layer 50 breaks fall on the position opposite to the opening 51 of the color filter section 41 and the light-shielding layer 50, resulting in black spots and display defects when the display substrate is displayed. By setting the light-shielding layer 50 on the side of the color filter layer 40 away from the substrate, it helps to improve the dark state effect of the display substrate in the non-display state. By setting the color filter layer 40, the color filter layer 40 can filter the incident external ambient light, reduce the amount of incident ambient light reflection, and reduce the loss of emitted light compared with the polarizer, thus improving the light output efficiency.
[0059] It should be noted that the cross-sectional view in Figure 1 is a partial schematic diagram obtained by cutting the display substrate along a direction perpendicular to the stacking direction of the film layers.

[0061] In one embodiment, as shown in FIG1, the display substrate further includes a driving circuit layer 60 located between the substrate 10 and the light-emitting layer 20. The driving circuit layer 60 includes a plurality of pixel circuits, which are used to drive sub-pixels 21. The pixel circuits and sub-pixels 21 can correspond one-to-one, and each pixel circuit is used to drive the corresponding sub-pixel 21.
[0062] In one embodiment, as shown in FIG1, the sub-pixel 21 includes a first electrode 211, a light-emitting material layer 212 located on the side of the first electrode 211 away from the substrate 10, and a second electrode 213 located on the side of the light-emitting material layer 212 away from the substrate 10. One of the first electrode 211 and the second electrode 213 is an anode, and the other is a cathode. In FIG1, the first electrode 211 is the anode, the second electrode 213 is the cathode, the cathode is a common electrode, and the cathodes of all sub-pixels 21 are connected to form a surface electrode. In some embodiments, the light-emitting material layer 212 is an organic light-emitting material layer, and the sub-pixel 21 is an OLED.
[0063] In one embodiment, as shown in FIG1, the pixel circuit may include a thin-film transistor 61 and a capacitor 62. The thin-film transistor 61 may include an active layer 611, a gate 612, a first electrode 613, and a second electrode 614. One of the first electrode 613 and the second electrode 614 is the source, and the other is the drain. The capacitor 62 includes a first electrode plate 621 and a second electrode plate 622 disposed opposite to each other. The pixel circuit layer may also include multiple signal lines, such as scan signal lines, data signal lines, power signal lines, etc.
[0064] In one embodiment, as shown in FIG1, the gate 612 and the first electrode 621 of the capacitor 62 are located on the same layer, the second electrode 622 of the capacitor 62 is located on the side of the first electrode 621 away from the substrate 10, and the first electrode 613 and the second electrode 614 of the thin film transistor 61 are located on the same layer, and are located on the side of the second electrode 622 away from the substrate 10. The driving circuit layer 60 further includes a gate insulating layer 63 located between the active layer 611 and the gate 612, a capacitor insulating layer 64 located between the gate 612 and the second electrode 622, an interlayer dielectric layer 65 located between the second electrode 622 and the first electrode 613, and a planarization layer 66 located between the first electrode 613 and the first electrode 211. The first electrode 211 is electrically connected to the second electrode 614 through a via penetrating the planarization layer 66, and the first electrode 613 and the second electrode 614 are in contact with the active layer 611 through vias penetrating the interlayer dielectric layer 65, the capacitor insulating layer 64 and the gate insulating layer 63, respectively.
[0065] In one embodiment, the light-emitting layer 20 includes at least three sub-pixels 21 with different emission colors. Each sub-pixel 21 corresponds one-to-one with a color filter 41, and the orthographic projection of each sub-pixel 21 onto the substrate 10 falls within the orthographic projection of the corresponding color filter 41 onto the substrate 10. The emission color of each sub-pixel 21 is the same as the color of the corresponding color filter 41 in the color filter layer 40. For example, the light-emitting layer 20 includes sub-pixels with a first emission color, sub-pixels with a second emission color, and sub-pixels with a third emission color. As shown in Figures 2 to 8, the color filter layer 40 includes a first color filter 42, a second color filter 43, and a third color filter 44. In some embodiments, the light-emitting layer 20 may include sub-pixels with a red emission color, sub-pixels with a green emission color, and sub-pixels with a blue emission color; in this case, the color filter layer 40 includes a red filter, a blue filter, and a green filter.
[0066] In one embodiment, as shown in FIG1, the light-emitting layer 20 further includes a pixel defining layer 22, which has a plurality of pixel openings 221. The pixel defining layer 22 is located on the side of the first electrode 211 away from the substrate 10. The pixel openings 221 correspond one-to-one with the sub-pixels 21, and each pixel opening 221 exposes at least a portion of the corresponding first electrode 211. At least a portion of the light-emitting material layer 212 of each sub-pixel 21 is located within the pixel opening 221. At least a portion of the second electrode 213 is located on the side of the pixel defining layer 22 away from the substrate 10. Each pixel opening 221 defines the light-emitting area of the corresponding sub-pixel 21; specifically, the area defined by the pixel opening 221 facing the bottom surface of the substrate 10 is the light-emitting area of the sub-pixel 21.
[0067] In one embodiment, as shown in FIG1, the side of the pixel opening 221 extends obliquely outward in the direction of the substrate 10 pointing towards the second electrode 213. The pixel defining layer 22 may be formed by an exposure and development process, resulting in the shape of the formed pixel opening 221.
[0068] In one embodiment, as shown in FIG1, the display substrate further includes an encapsulation layer 30 located between the light-emitting layer 20 and the light-shielding layer 50, with both the color filter layer 40 and the light-shielding layer 50 located on the side of the encapsulation layer 30 away from the substrate 10. The encapsulation layer 30 may be a thin-film encapsulation layer, comprising alternating organic and inorganic layers, wherein the layer with the greatest distance from the substrate 10 is an inorganic layer. In some embodiments, the thin-film encapsulation layer may include two inorganic layers and an organic layer located between the two inorganic layers.
[0069] In one embodiment, as shown in FIG1, the display substrate further includes a touch structure layer 80 located between the encapsulation layer 30 and the color filter layer 40. The touch structure layer 80 includes a first touch electrode layer 83, a second touch electrode layer 81 located on the side of the first touch electrode layer 83 away from the substrate 10, an insulating material layer 84 located between the first touch electrode layer 83 and the second touch electrode layer 81, and an insulating protective layer 86 located on the side of the second touch electrode layer 81 away from the substrate 10. The insulating protective layer 86 covers the second touch electrode layer 81. The second touch electrode layer 81 may include a plurality of first touch electrodes, a plurality of second touch electrodes, and a plurality of first connecting portions. The first touch electrode layer 83 includes a plurality of second connecting portions. Adjacent first touch electrodes can be connected through the first connecting portions, and adjacent second touch electrodes can be electrically connected through the second connecting portions. The materials of the insulating protective layer 86 and the insulating material layer 84 may be organic materials, and the surface flatness of the insulating protective layer 86 and the insulating material layer 84 away from the substrate 10 is relatively good. In some embodiments, the materials of the insulating protective layer 86 and the insulating material layer 84 may be organic resins.
[0070] In one embodiment, as shown in FIG1, the display substrate further includes an insulating layer 70, which has a plurality of through holes 71, each of the color filter portions 41 being partially located within one of the through holes 71. The color filter portions 41 and the through holes 71 can correspond one-to-one, with each color filter portion 41 partially located within its corresponding through hole 71. In the direction from the substrate 10 to the insulating layer 70, the sides of the through holes 71 extend obliquely outward. The through holes 71 of the insulating layer 70 can be formed using an exposure and development process, resulting in the shape of the formed through holes 71.
[0071] Furthermore, the refractive index of the insulating layer 70 is less than that of the color filter 41. With this configuration, when light emitted from the sub-pixel 21 is incident on the side of the through-hole 71 of the insulating layer 70 via the color filter 41, most of the light undergoes total internal reflection at the side of the through-hole 71 and exits through the light-shielding layer 50, thereby helping to reduce light loss and improve the light extraction efficiency of the display substrate. In some embodiments, the refractive index of the insulating layer 70 ranges from 1.4 to 1.55, and the refractive index of the color filter 41 ranges from 1.6 to 1.7. This larger difference in refractive index between the color filter 41 and the insulating layer 70 improves the total internal reflection efficiency of light incident on the side of the through-hole 71 of the insulating layer 70.
[0072] In one embodiment, as shown in FIG1, the insulating layer 70 is reused as an insulating protective layer 86. This helps to reduce the thickness of the display substrate. In other embodiments, the insulating layer 70 and the insulating protective layer 86 are different film layers, with the insulating layer 70 located on the side of the insulating protective layer 86 away from the substrate 10.
[0073] In one embodiment, as shown in FIG1, the display substrate further includes a protective layer 85 located on the side of the light-shielding layer 50 away from the substrate 10. The protective layer 85 covers the side of the opening 51 of the light-shielding layer 50 and the surface of the light-shielding layer 50 away from the substrate 10. The material of the protective layer 85 may be an organic resin.
[0074] In one embodiment, as shown in Figures 9 and 10, the edge of each through-hole 71 of the insulating layer 70 facing the orthogonal projection of the bottom surface of the substrate 10 onto the substrate 10 is a first edge 711, and the edge of each color filter portion 41 facing the orthogonal projection onto the substrate 10 is a second edge 4011, with the first edge 711 located inside the corresponding second edge 4011; the edge of each pixel opening 221 facing the orthogonal projection of the bottom surface of the substrate 10 onto the substrate 10 is a third edge 2211, with the third edge 2211 located inside the corresponding first edge 711. By setting the third edge 2211 to be inside the corresponding first edge 711, more light emitted by the sub-pixel 21 can be incident on the portion of the color filter 41 located inside the through hole 71 and reflected by the insulating layer 70 before being emitted, which helps to improve the light emission rate. By setting the first edge 711 to be inside the corresponding second edge 4011, that is, the color filter 41 partially covers the insulating layer 70, the gap between adjacent color filters 41 can be smaller, which helps to prevent the light-shielding layer 50 from breaking.
[0075] In one embodiment, as shown in Figures 9 and 10, the edge of each opening 51 facing the orthographic projection of the bottom surface of the substrate 10 onto the substrate 10 is a fourth edge 511, which is located outside the corresponding first edge 711. This configuration reduces the amount of light emitted through the through-holes 71 of the insulating layer 70 absorbed by the light-shielding layer 50, thereby reducing light loss and improving the light extraction efficiency of the display substrate.

Wherein, the second edge 4012 of the first color filter is located outside the corresponding fourth edge 512, the fourth edge 512 is located outside the corresponding first edge 712, and the first edge 712 is located outside the corresponding third edge 2212; the second edge 4013 of the second color filter is located outside the corresponding fourth edge 513, the fourth edge 513 is located outside the corresponding first edge 713, and the first edge 713 is located outside the corresponding third edge 2213; the second edge 4014 of the third color filter is located outside the corresponding fourth edge 514, the fourth edge 514 is located outside the corresponding first edge 714, and the first edge 714 is located outside the corresponding third edge 2214.
[0077] In one embodiment, as shown in Figures 11 and 12, at least one through-hole 71 of the insulating layer 70 has a protrusion 701 on its side surface, the protrusion 701 extending toward the center of the through-hole 71. By providing a protrusion 701 on the side surface of the through-hole 71, the area of the side surface of the through-hole 701 can be increased, thereby allowing more light incident on the side surface of the through-hole 71 to be reflected, which is beneficial to improving the forward light emission of the display substrate.
[0078] In one embodiment, the side surface of the protrusion 701 is curved.
[0079] In some embodiments, the side surface of the protrusion 701 may be conical, and the cross-sectional area of the protrusion 701 parallel to the substrate 10 gradually decreases in the direction from the substrate 10 to the color filter layer. Since the outer surface of the protrusion 701 is a conical or frustum-shaped arc-shaped side surface, compared to the scheme where the side surface of the through hole 71 is not provided with a protrusion, most of the light rays incident from the color filter section 41 to the side surface of the protrusion 701 at various directions can exit at similar exit angles after being reflected by the side surface of the protrusion 701, which helps to increase the forward light emission of the display substrate.
[0080] In some embodiments, the side surface of the protrusion 701 is cylindrical, or the cross-section of the protrusion 701 parallel to the substrate 10 is semi-elliptical. With this configuration, compared to the scheme where the side surface of the through hole 71 is not provided with a protrusion, the light incident from the color filter section 41 to the side surface of the protrusion 701 at various directions is reflected by the side surface of the protrusion 701, which helps to adjust the light incident at various directions to a direction perpendicular to the light emitting surface of the display panel, thereby increasing the forward light emission of the display substrate.
[0081] In one embodiment, as shown in Figures 11 and 12, each of the through holes 71 has a plurality of protrusions 701 on its side surface, and the plurality of protrusions 701 on the side surface of the same through hole 71 are evenly spaced along the circumference. By providing a plurality of protrusions 701 on the side surface of the through hole 71, more light can be reflected on the side surface of the protrusions 701, thereby improving the light efficiency of the display panel. In some embodiments, as shown in Figures 11 and 12, four protrusions 701 are provided on the side surface of the same through hole 71, and the four protrusions 701 are evenly spaced along the circumference.
[0082] In one embodiment, as shown in Figures 11 and 12, the axis passing through the center of the color filter 41 through the protrusion 412 of the color filter 41 is the first axis 4121, and the axis passing through the center of the through hole 71 through the through hole 71 is the second axis 7011. The angle between the first axis 4121 of the protrusion 412 and the second axis 7011 of the two protrusions 701 adjacent to the protrusion 412 in the corresponding through hole 71 is the same. This arrangement helps to reduce color shift of light from a side viewing angle and improve the user experience. The center of the color filter 41 coincides with the center of the corresponding through hole.
[0083] Further, as shown in Figures 11 and 12, the through hole 71 is provided with four protrusions 701, which are evenly spaced in the circumferential direction. The angle between the first axis 4121 of the protrusion 412 and the second axis 7011 of the corresponding through hole 71 and the two adjacent protrusions 701 of the protrusion 412 is 45°. In one embodiment, as shown in Figures 2 to 8, all the color filter portions 41 of the color filter layer 40 are arranged as a plurality of first filter portion groups and a plurality of second filter portion groups. The plurality of first filter portion groups are arranged along a first direction Y, and the plurality of second filter portion groups are arranged along a second direction X. Each first filter portion group includes a plurality of color filter portions 41 arranged in the second direction X, and each second filter portion group includes a plurality of color filter portions 41 arranged in the first direction Y. The first direction Y intersects the second direction X. In some embodiments, the first direction Y is perpendicular to the second direction X. In some embodiments, the first direction Y is a column direction and the second direction X is a row direction, that is, all the color filter portions 41 of the color filter layer 40 are arranged in multiple rows and columns. The following description will take the first direction Y as the column direction and the second direction X as the row direction as an example.
[0084] In one embodiment, the color filter layer 40 includes a first color filter 42, a second color filter 43, and a third color filter 44. In two adjacent rows of color filters, the first color filter 42 and the second color filter 43 are arranged alternately in one row, while the other row consists entirely of the third color filter 44. In two adjacent columns of color filters, the first color filter 42 and the second color filter 43 are arranged alternately in one column, while the other column consists entirely of the third color filter 44. Multiple color filters located in the same row are arranged along the X direction, and multiple color filters located in the same column are arranged along the Y direction.
[0085] In one embodiment, as shown in Figures 2 to 8, the outlines of at least two adjacent color filter portions 41 have the same shape for their opposite portions. This arrangement helps to reduce the gap between the two adjacent color filter portions 41, thereby further reducing the risk of breakage of the light-shielding layer 50.
[0086] Furthermore, as shown in Figures 2 to 8, the corresponding portions of the outlines of any two adjacent color filter sections 41 in the row direction X have the same shape, and the corresponding portions of the outlines of any two adjacent color filter sections 41 in the column direction Y also have the same shape. This configuration allows for a smaller gap between any two adjacent color filter sections 41, effectively mitigating the problem of breakage in the light-shielding layer 50.
[0087] In one embodiment, as shown in Figures 2 to 5, the opposing portions of the outlines of at least two adjacent color filter portions 41 are straight lines, and these opposing, straight portions of the outlines of the two adjacent color filter portions 41 are parallel to each other. This arrangement ensures that the gap between the opposing portions of two adjacent color filter portions 41 is the same, effectively improving the problem of large gaps between two adjacent color filter portions 41 at certain locations. Here, "parallel" refers to approximately parallel, including cases where the angle between them is very small; for example, an angle less than 10° can be considered parallel.
[0088] As shown in Figure 13, segment 431 of the outline of the color filter 43 is opposite to segment 441 of the outline of the adjacent color filter 44. Both segments 431 and 441 are straight lines and parallel to each other. Segment 432 of the outline of the color filter 43 is opposite to segment 442 of the outline of the adjacent color filter 44. Both segments 432 and 442 are straight lines and parallel to each other. Segment 421 of the outline of the color filter 42 is opposite to segment 443 of the outline of the adjacent color filter 44. Both segments 421 and 443 are straight lines and parallel to each other. Segment 422 of the outline of the color filter 42 is opposite to segment 433 of the outline of the adjacent color filter 43. Both segments 422 and 433 are straight lines and parallel to each other.
[0089] In one embodiment, as shown in Figures 6 to 8, the opposing portions of the outlines of at least two adjacent color filter portions 41 are curved, and the opposing portions of the outlines of at least two adjacent color filter portions 41 have the same shape. By setting the portions of the outlines of the color filter portions 41 to be curved, the shape of the color filter portions 41 can be flexibly designed, thereby allowing for flexible adjustment of the area of the color filter portions 41 for various colors, in order to optimize the dark state effect and white balance effect of the display substrate in the non-display state.
[0090] As shown in Figure 14, the outline of the color filter section 43 is circular, and the segment 424 of the outline of each color filter section 42 is opposite to the outline of the adjacent color filter section 43, and each segment 424 is an arc; the segment 423 of the outline of each color filter section 42 is opposite to the segment 445 of the outline of the adjacent color filter section 44, and both the segment 423 and the segment 445 are curves including two straight lines and one arc.
[0091] In one embodiment, at least one color filter 41 is surrounded by a plurality of color filters 41, the outline of the surrounded color filters 41 being a smooth closed curve, and the portions of the outlines of the plurality of color filters 41 opposite to the surrounded color filters 41 lying on the same smooth closed curve. This arrangement helps to reduce the gap between the color filter and the surrounding color filters, thereby effectively reducing the probability of the light-shielding layer 50 breaking.
[0092] Furthermore, the geometric center of the smooth closed curve containing the portion of the outline of the plurality of color filters and the portion opposite to the surrounded color filter is the first center, and the geometric center of the outline of the surrounded color filter 41 is the second center, with the first center coinciding with the second center. This arrangement ensures a more uniform gap between the surrounded color filter 41 and its surrounding components, preventing the light-shielding layer 50 from breaking at a location where the distance between the surrounded color filter 41 and an adjacent color filter 41 is too large.
[0093] As shown in Figure 14, the outline of the color filter section 43 is circular. Four color filter sections 42 and four color filter sections 44 surround the same color filter section 43. The segments 424 of the outlines of the four color filter sections 42 are opposite to the outlines of the color filter section 43, and the segments 444 of the outlines of the four color filter sections 44 are opposite to the outlines of the color filter section 43. The four segments 424 and the four segments 444 are all arcs and are on the same circle. The center of the circle coincides with the center of the outline of the color filter section 43.
[0094] In one embodiment, at least two adjacent color filter portions 41 have partially overlapping outlines. This eliminates gaps between portions of the two adjacent color filter portions, effectively preventing breakage of the light-shielding layer 50 at those locations. In some embodiments, multiple color filter portions 41 exist without gaps between adjacent color filter portions 41.
[0095] In one embodiment, the maximum width of the gap between any two adjacent color filter sections 41 is less than or equal to 3 μm. When the maximum width of the gap between two adjacent color filter sections 41 is less than or equal to 3 μm, the light-shielding layer 50 will not break at this gap. This configuration effectively avoids color separation and black spot defects caused by breakage of the light-shielding layer during display substrate display. In some embodiments, the maximum width of the gap between any two adjacent color filter sections 41 is less than or equal to 1 μm.
[0096] In one embodiment, as shown in Figures 2 to 8, the plurality of color filter portions 41 in the color filter layer 40 each include a main body portion 411 and at least one protrusion 412 connected to the main body portion 411; the protrusion 412 fills the space between the main bodies 411 of two adjacent color filter portions 41 located in the same row; the protrusion 412 fills the space between the main bodies 411 of two adjacent color filter portions 41 located in the same column. This configuration results in a smaller gap between the main bodies 411 of two adjacent color filter portions 41 located in the same row and a smaller gap between the main bodies 411 of two adjacent color filter portions 41 located in the same column, effectively improving the problem of large gaps between adjacent color filter portions 41 in the color filter layer 40, and thus effectively improving the problem of breakage of the light-shielding layer 50.
[0097] In one embodiment, the color filter layer includes at least three different color filter portions; the protrusions filling any two adjacent main portions are all protrusions of the same color.
[0098] As shown in Figure 2, each of the first color filter portions 42 includes protrusions 412 on opposite sides in the row direction X and on opposite sides in the column direction Y. In the color filter layer 40, the protrusions 412 filling the space between the main body portions 411 of two adjacent color filter portions 41 in the same row and the protrusions 412 filling the space between any two adjacent main body portions 411 in the same column are all protrusions of the first color filter portion 42. Other color filter portions besides the first color filter portion 42 may all include a main body portion. Specifically, the protrusion 412 of the first color filter 42 is filled between the main body portion 411 of the first color filter portion 42 and the main body portion 411 of the second color filter portion 43 located in the same row and adjacent; the protrusion 412 of the first color filter portion 42 is filled between the main body portions 411 of the two third color filter portions 44 located in the same row and adjacent; the protrusion 412 of the first color filter portion 42 is filled between the main body portion 411 of the first color filter portion 42 and the main body portion 411 of the second color filter portion 43 located in the same column and adjacent; the protrusion 412 of the first color filter portion 42 is filled between the main body portions 411 of the two third color filter portions 44 located in the same column and adjacent.
[0099] As shown in Figure 3, each of the second color filter portions 43 includes protrusions 412 on opposite sides in the row direction X and on opposite sides in the column direction Y. In the color filter layer 40, the protrusions 412 filling the space between the main body portions 411 of two adjacent color filter portions 41 in the same row and the protrusions 412 filling the space between any two adjacent main body portions 411 in the same column are all protrusions of the second color filter portion 43. Specifically, the body portion 411 of the first color filter portion 42 and the body portion 411 of the second color filter portion 43 located in the same row and adjacent are filled with the protrusion 412 of the second color filter portion 43; the body portion 411 of the two third color filter portions 44 located in the same row and adjacent are filled with the protrusion 412 of the second color filter portion 43; the body portion 411 of the first color filter portion 42 and the body portion 411 of the second color filter portion 43 located in the same column and adjacent are filled with the protrusion 412 of the second color filter portion 43; the body portion 411 of the two third color filter portions 44 located in the same column and adjacent are filled with the protrusion 412 of the second color filter portion 43.
[0100] As shown in Figures 5 and 8, each of the third color filter units 44 includes protrusions 412 on opposite sides in the row direction X and on opposite sides in the column direction Y. In the color filter layer 40, the protrusions 412 filling the space between the main body portions 411 of two adjacent color filter units 41 in the same row and the protrusions 412 filling the space between any two adjacent main body portions 411 in the same column are all protrusions of the third color filter unit 44, and each third color filter unit 44 is an integral structure. Specifically, a protrusion 412 of a third color filter 44 is filled between the main body portion 411 of the first color filter portion 42 and the main body portion 411 of the second color filter portion 43 located in the same row and adjacent to each other; a protrusion 412 of a third color filter 44 is also filled between the main body portions 411 of two adjacent third color filter portions 44 located in the same row and adjacent to each other; similarly, a protrusion 412 of a third color filter 44 is filled between the main body portions 411 of the first color filter portion 42 and the main body portion 411 of the second color filter portion 43 located in the same column and adjacent to each other; and a protrusion 412 of a third color filter 44 is also filled between the main body portions 411 of two adjacent third color filter portions 44 located in the same column and adjacent to each other. By setting all the third color filter portions 44 as a single integrated structure, there are no gaps between adjacent third color filter portions 44, which further improves the problem of light-shielding layer breakage.
[0101] In one embodiment, the color filter layer 40 includes at least three different color filter portions; at least two adjacent color filter portions 41 have protrusions of two colors filling the space between their main body portions 411. By providing protrusions 412 of two colors filling the space between the main body portions 411 of two adjacent color filter portions 41, it is helpful to adjust the area size of the two color filter portions 41, thereby helping to improve the dark state effect of the display substrate in the non-display state.
[0102] Further, as shown in FIG4, the first color filter 42 and the second color filter 43 are respectively provided with protrusions 412 on opposite sides in the row direction X and on opposite sides in the column direction Y; the protrusions 412 of the first color filter 42 and the protrusions 412 of the second color filter 43 are filled between the main body portions 411 of the two color filter portions 41 located in the same row; the protrusions 412 of the first color filter 42 and the protrusions 412 of the second color filter 43 are filled between the main body portions 411 of the two color filter portions 41 located in the same column. In the embodiment shown in Figure 4, the main body portion 411 of the first color filter portion 42 and the main body portion 411 of the second color filter portion 43 located in the same row and adjacent are filled with the protrusions 412 of the first color filter portion 42 and the protrusions 412 of the second color filter portion 43. The main body portion 411 of the two third color filter portions 44 located in the same row and adjacent are filled with the protrusions 412 of the first color filter portion 42 and the protrusions 412 of the second color filter portion 43. The main body portion 411 of the first color filter portion 42 and the main body portion 411 of the second color filter portion 43 located in the same column and adjacent are filled with the protrusions 412 of the first color filter portion 42 and the protrusions 412 of the second color filter portion 43. The main body portion 411 of the two third color filter portions 44 located in the same column and adjacent are filled with the protrusions 412 of the first color filter portion 42 and the protrusions 412 of the second color filter portion 43. This configuration is more conducive to the total area of the first color filter 42 and the second color filter 43, and helps to improve the dark state effect of the display substrate in the non-display state.
[0103] Further, the first color is red, the second color is blue, the main body of the first color filter 42 and the main body of the second color filter 43 have the same area, and the protrusions of the first color filter 42 and the protrusions of the second color filter 43 have the same area. This configuration effectively reduces the difference between the total area of the first color filter 42 and the total area of the second color filter 43 in the color filter layer 40, resulting in better dark-state effects of the display substrate in non-display states. In some embodiments, the main body 411 of the first color filter 42 and the second color filter 43 have the same shape, and the protrusions 412 of the first color filter 42 and the second color filter 43 have the same shape.
[0104] In one embodiment, as shown in Figures 6 and 7, at least one of the color filter units 41 has protrusions 413 on opposite sides of a third direction Z1, which intersects both the row direction X and the column direction Y. This arrangement results in a smaller gap between the color filter unit 41 and adjacent color filter units 41 on the third direction Z1, further reducing the risk of breakage of the light-shielding layer 50. In the embodiment shown in Figure 6, half of the color filter units 44 located in the same row have protrusions 413 on opposite sides of a third direction Z1. In the embodiment shown in Figure 7, each color filter unit 43 has protrusions 413 on opposite sides of a third direction Z1.
[0105] In one embodiment, as shown in Figures 6 and 7, at least one of the color filter portions 41 has protrusions 414 on opposite sides in the fourth direction Z2, which intersects both the row direction X and the column direction Y, and is perpendicular to the third direction Z1. This arrangement results in a smaller gap between the color filter portion 41 and adjacent color filter portions 41 in the fourth direction Z2, further reducing the risk of breakage of the light-shielding layer 50. In the embodiment shown in Figure 6, half of the color filter portions 44 in the same row have protrusions 414 on opposite sides in the fourth direction Z2. In the embodiment shown in Figure 7, each color filter portion 43 has protrusions 414 on opposite sides in the fourth direction Z2.
[0106] Preferably, as shown in FIG7, each color filter 43 has a protrusion 413 on each of the opposite sides in the third direction Z1, and each color filter 43 has a protrusion 414 on each of the opposite sides in the fourth direction Z2.
[0107] In one embodiment, the distance from the surface of each color filter portion 41 in the color filter layer 40 away from the substrate 10 is the same. This arrangement ensures that the surfaces of each color filter portion 41 away from the substrate 10 are on the same plane, thus avoiding the risk of breakage of the light-shielding layer 50 due to height differences between different color filter portions 41.
