[0061] In one embodiment, as Figure 1 shown, 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 for driving the sub-pixels 21. The pixel circuits and the sub-pixels 21 can correspond one by one, and each pixel circuit is used to drive the corresponding sub-pixel 21.

[0062] In one embodiment, as Figure 1 shown, 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. Figure 1In the first electrode 211 is the anode, the second electrode 213 is the cathode, and the cathode is a common electrode. The cathodes of all sub-pixels 21 are connected to form a planar 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 Figure 1 shown, the pixel circuit may include a thin-film transistor 61 and a capacitor 62.

[0064] In one embodiment, as Figure 1 shown, the gate 612 and the first electrode plate 621 of the capacitor 62 are located on the same layer, the second electrode plate 622 of the capacitor 62 is located on the side away from the substrate 10 of the first electrode plate 621, the first pole 613 and the second pole 614 of the thin-film transistor 61 are located on the same layer, and are located on the side away from the substrate 10 of the second electrode plate 622.

[0065] In one embodiment, the light-emitting layer 20 includes at least three sub-pixels 21 with different light-emitting colors. The sub-pixels 21 and the color filter portion 41 may correspond one by one, and the orthographic projection of each sub-pixel 21 on the substrate 10 falls within the orthographic projection of the corresponding color filter portion 41 on the substrate 10; the light-emitting color of each sub-pixel 21 is the same as the color of the corresponding color filter portion 41 in the color filter layer 40. For example, the light-emitting layer 20 includes a sub-pixel with a first color, a sub-pixel with a second color, and a sub-pixel with a third color; as Figures 2 to 8 shown, the color filter layer 40 includes a first color filter portion 42, a second color filter portion 43, and a third color filter portion 44. In some embodiments, the light-emitting layer 20 may include a sub-pixel with a red light-emitting color, a sub-pixel with a green light-emitting color, and a sub-pixel with a blue light-emitting color, then the color filter layer 40 includes a red filter portion, a blue filter portion, and a green filter portion.

[0066] In one embodiment, as Figure 1 shown, the light-emitting layer 20 further includes a pixel definition layer 22, and the pixel definition layer is provided with a plurality of pixel openings 221. The pixel definition layer 22 is located on a side of the first electrode 211 away from the substrate 10. The pixel openings 221 and the sub-pixels 21 can be in one-to-one correspondence, and at least a part of the corresponding first electrode 211 is exposed through each pixel opening 221. At least a part of the light-emitting material layer 212 of each sub-pixel 21 is located within the pixel opening 221. The second electrode 213 is at least partially located on a side of the pixel definition layer 22 away from the substrate 10. Each of the pixel openings 221 defines a light-emitting area of the corresponding sub-pixel 21. Specifically, the area defined by the bottom surface of the pixel opening 221 facing the substrate 10 is the light-emitting area of the sub-pixel 21.

[0067] In one embodiment, as Figure 1 shown, in a direction from the substrate 10 towards the second electrode 213, the side surface of the pixel opening 221 extends obliquely outwards. The pixel definition layer 22 can be formed by an exposure and development process such that the shape of the formed pixel opening 221 is like this.

[0068] In one embodiment, as Figure 1 shown, the display substrate further includes a packaging layer 30 located between the light-emitting layer 20 and the light-shielding layer 50, and both the color filter layer 40 and the light-shielding layer 50 are located on a side of the packaging layer 30 away from the substrate 10. The packaging layer 30 can be a thin-film packaging layer. The thin-film packaging layer includes an organic layer and an inorganic layer arranged alternately, and the layer with the largest distance from the substrate 10 is the inorganic layer. In some embodiments, the thin-film packaging layer can include two inorganic layers and an organic layer located between the two inorganic layers.

[0069] In one embodiment, as Figure 1As shown, 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 protection layer 86 located on the side of the second touch electrode layer 81 away from the substrate 10, and the insulating protection 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 connection portions, the first touch electrode layer 83 includes a plurality of second connection portions, adjacent first touch electrodes may be connected through the first connection portions, and adjacent second touch electrodes may be electrically connected through the second connection portions. The materials of the insulating protection layer 86 and the insulating material layer 84 may be organic materials, and the flatness of the surfaces of the insulating protection layer 86 and the insulating material layer 84 away from the substrate 10 is relatively good. In some embodiments, the materials of the insulating protection layer 86 and the insulating material layer 84 may be organic resins.

[0070] In one embodiment, as Figure 1 shown, the display substrate further includes an insulating layer 70, the insulating layer 70 is provided with a plurality of through holes 71, and each color filter portion 41 is partially located in one of the through holes 71. The color filter portions 41 and the through holes 71 may correspond one by one, and each color filter portion 41 is partially located in the corresponding through hole 71. In the direction from the substrate 10 to the insulating layer 70, the side surface of the through hole 71 extends obliquely outward. The through holes 71 of the insulating layer 70 may be formed by an exposure and development process, such that the formed through holes 71 have such a shape.

[0071] Furthermore, the refractive index of the insulating layer 70 is less than the refractive index of the color filter portion 41. With such a setting, after the light emitted by the sub-pixel 21 is incident on the side surface of the through hole 71 of the insulating layer 70 from the color filter portion 41, most of the light undergoes total internal reflection on the side surface of the through hole 71 of the insulating layer 70 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 range of the insulating layer 70 is 1.4 to 1.55, and the refractive index range of the color filter portion 41 is 1.6 to 1.7. In this way, the difference in refractive index between the color filter portion 41 and the insulating layer 70 is relatively large, which can improve the total internal reflection efficiency of the light incident on the side surface of the through hole 71 of the insulating layer 70.

[0072] In one embodiment, as Figure 1 shown, the insulating layer 70 is reused as the insulating protection layer 86. This helps to reduce the thickness of the display substrate. In other embodiments, the insulating layer 70 and the insulating protection layer 86 are different film layers, and the insulating layer 70 is located on the side of the insulating protection layer 86 away from the substrate 10.

[0073] In one embodiment, as Figure 1 shown, the display substrate further includes a protective layer 85 on a side of the light-shielding layer 50 away from the substrate 10. The protective layer 85 covers the side surface 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 can be an organic resin.

[0074] In one embodiment, as Figure 9 and Figure 10 shown, the edge of the orthographic projection of each through hole 71 of the insulating layer 70 on the bottom surface of the substrate 10 is a first edge 711, and the edge of the orthographic projection of each color filter portion 41 on the substrate 10 is a second edge 4011. The first edge 711 is located inside the corresponding second edge 4011; the edge of the orthographic projection of each pixel opening 221 on the bottom surface of the substrate 10 is a third edge 2211, and the third edge 2211 is located inside the corresponding first edge 711. By setting the third edge 2211 inside the corresponding first edge 711, more light emitted by the sub-pixel 21 can be incident on the portion of the color filter portion 41 located inside the through hole 71 and exit after being reflected by the insulating layer 70, which is beneficial to improving the light extraction rate; by setting the first edge 711 inside the corresponding second edge 4011, that is, the color filter portion 41 partially covers the insulating layer 70, the gap between adjacent color filter portions 41 can be made smaller, which helps to avoid the light-shielding layer 50 from breaking.

[0075] In one embodiment, as Figure 9 and Figure 10 shown, the edge of the orthographic projection of each opening 51 on the bottom surface of the substrate 10 is a fourth edge 511, and the fourth edge 511 is located outside the corresponding first edge 711. With this setting, the amount of light emitted through the through hole 71 of the insulating layer 70 absorbed by the light-shielding layer 50 can be reduced, thereby reducing light loss and improving the light extraction rate of the display substrate.

[0076] As Figure 9 and Figure 10As shown, the edge of the orthographic projection of the first color filter portion on the substrate 10 is the second edge 4012, the edge of the orthographic projection of the second color filter portion on the substrate 10 is the second edge 4013, and the edge of the orthographic projection of the third color filter portion on the substrate 10 is the second edge 4014; the first edge of the through hole 71 corresponding to the first color filter portion is the first edge 712, the first edge of the through hole 71 corresponding to the second color filter portion is the first edge 713, and the first edge of the through hole 71 corresponding to the third color filter portion is the first edge 714; the third edge of the pixel opening 221 corresponding to the first color filter portion is the third edge 2212, the third edge of the pixel opening 221 corresponding to the second color filter portion is the third edge 2213, and the third edge of the pixel opening 221 corresponding to the third color filter portion is the third edge 2214; the edge of the orthographic projection of the bottom surface of the opening 51 corresponding to the first color filter portion facing the substrate 10 on the substrate 10 is the fourth edge 512, the edge of the orthographic projection of the bottom surface of the opening 51 corresponding to the second color filter portion facing the substrate 10 on the substrate 10 is the fourth edge 513, and the edge of the orthographic projection of the bottom surface of the opening 51 corresponding to the third color filter portion facing the substrate 10 on the substrate 10 is the fourth edge 514. Among them, the second edge 4012 of the first color filter portion 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 portion 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 portion 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 Figure 11 and Figure 12 shown, a protrusion 701 is provided on the side surface of at least one through hole 71 of the insulating layer 70, and the protrusion 701 extends towards the center of the through hole 71 where it is located. By providing the protrusion 701 on the side surface of the through hole 71, the area of the side surface of the through hole 71 can be increased, and further, the amount of light reflected from the side surface of the through hole 71 where the incident light enters can be increased, which is beneficial to improving the forward light output of the display substrate.

[0078] In one embodiment, the side surface of the protrusion 701 is a curved surface.

[0079] In some embodiments, the side surface of the protrusion 701 may be a conical surface, and in the direction from the substrate 10 towards the color filter layer, the cross-sectional area of the protrusion 701 parallel to the substrate 10 gradually decreases. Since the outer side surface of the protrusion 701 is a conical surface or an arcuate side surface of a frustum of a cone, compared with the solution where the side surface of the through hole 71 is not provided with a protrusion, for the light rays incident on the side surface of the protrusion 701 from various directions by the color filter portion 41, after being reflected by the side surface of the protrusion 701, most of the light rays can be emitted at a similar emission angle, which helps to increase the forward light emission amount of the display substrate.

[0080] In some embodiments, the side surface of the protrusion 701 is a cylindrical surface, or the cross-section of the protrusion 701 parallel to the substrate 10 is semi-elliptical. With such a setting, compared with the solution where the side surface of the through hole 71 is not provided with a protrusion, for the light rays incident on the side surface of the protrusion 701 from various directions by the color filter portion 41, after being reflected by the side surface of the protrusion 701, it is beneficial to adjust the light rays incident from various directions to the direction perpendicular to the light-emitting surface of the display panel, increasing the forward light emission amount of the display substrate.

[0081] In one embodiment, as Figure 11 and Figure 12 shown, multiple protrusions 701 are provided on the side surface of each through hole 71, and the multiple protrusions 701 on the side surface of the same through hole 71 are evenly spaced along the circumferential direction. By providing multiple protrusions 701 on the side surface of the through hole 71, more light rays can be reflected on the side surface of the protrusion 701, improving the light efficiency of the display panel. In some embodiments, as Figure 11 and Figure 12 shown, 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 circumferential direction.

[0082] In one embodiment, as Figure 11 and Figure 12 shown, the axis passing through the center of the protruding portion 412 of the color filter portion 41 is the first axis 4121, the axis passing through the center of the protrusion 701 of the through hole 71 is the second axis 7011, and the angle between the first axis 4121 of the protruding portion 412 and the second axes 7011 of the two protrusions 701 adjacent to the protruding portion 412 in the corresponding through hole 71 is the same. With such a setting, it helps to reduce the color shift of the side-viewing angle light rays and improve the user experience. Among them, the center of the color filter portion 41 coincides with the center of the corresponding through hole.

[0083] Furthermore, as Figure 11 and Figure 12As shown, the through hole 71 is provided with four protrusions 701, and the four protrusions 701 are evenly spaced in the circumferential direction. The included angle between the first axis 4121 of the protruding portion 412 and the second axes 7011 of two adjacent protrusions 701 corresponding to the through hole 71 and the protruding portion 412 is 45°. In one embodiment, as Figures 2 to 8 As shown, all the color filter portions 41 of the color filter layer 40 are arranged into 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 the first direction Y, and the plurality of second filter portion groups are arranged along the second direction X. Each of the first filter portion groups includes a plurality of color filter portions 41 arranged in the second direction X, and the second filter portion groups include 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 the column direction, and the second direction X is the row direction, that is, all the color filter portions 41 of the color filter layer 40 are arranged in multiple rows and multiple columns. Hereinafter, the case where the first direction Y is the column direction and the second direction X is the row direction will be taken as an example for introduction.

[0084] In one embodiment, the color filter layer 40 includes a first color filter portion 42, a second color filter portion 43, and a third color filter portion 44; in adjacent two rows of color filter portions, in one row of color filter portions, the first color filter portion 42 and the second color filter portion 43 are alternately arranged, and in the other row of color filter portions, all are the third color filter portion 44; in adjacent two columns of color filter portions, in one column of color filter portions, the first color filter portion 42 and the second color filter portion 43 are alternately arranged, and in the other column of color filter portions, all are the third color filter portion 44. The multiple color filter portions located in the same row are arranged along the X direction, and the multiple color filter portions located in the same column are arranged along the Y direction.

[0085] In one embodiment, as Figures 2 to 8 As shown, the opposite parts of the contour lines of at least two adjacent color filter portions 41 have the same shape. With such a setting, it is helpful to reduce the gap between the two adjacent color filter portions 41, thereby further reducing the risk of the light-shielding layer 50 breaking.

[0086] Further, as Figures 2 to 8 As shown, the opposite parts of the contour lines of any two adjacent color filter portions 41 in the row direction X have the same shape, and the opposite parts of the contour lines of any two adjacent color filter portions 41 in the column direction Y have the same shape. With such a setting, the gap between any two adjacent color filter portions 41 can be set to be smaller, and the problem of the light-shielding layer 50 breaking can be effectively improved.

[0087] In one embodiment, as Figures 2 to 5As shown, the opposite portions of the contour lines of at least two adjacent color filter portions 41 are straight lines, and the opposite and straight portions of the contour lines of the two adjacent color filter portions 41 are parallel to each other. With this arrangement, the gaps between the opposite portions of two adjacent color filter portions 41 are the same, which can effectively improve the problem that the gaps between two adjacent color filter portions 41 are relatively large at certain positions. Here, "parallel" means approximately parallel, including the case of parallel and a very small included angle between the two. For example, if the included angle between the two is less than 10°, it can be considered parallel.

[0088] As Figure 13 shown, the section 431 of the contour line of the color filter portion 43 is opposite to the section 441 of the contour line of the adjacent color filter portion 44. Both the section 431 and the section 441 are straight lines and are parallel to each other; the section 432 of the contour line of the color filter portion 43 is opposite to the section 442 of the contour line of the adjacent color filter portion 44. Both the section 432 and the section 442 are straight lines and are parallel to each other; the section 421 of the contour line of the color filter portion 42 is opposite to the section 443 of the contour line of the adjacent color filter portion 44. Both the section 421 and the section 443 are straight lines and are parallel to each other; the section 422 of the contour line of the color filter portion 42 is opposite to the section 433 of the contour line of the adjacent color filter portion 43. Both the section 422 and the section 433 are straight lines and are parallel to each other.

[0089] In one embodiment, as Figures 6 to 8 shown, the opposite portions of the contour lines of at least two adjacent color filter portions 41 are curved, and the shapes of the opposite portions of the contour lines of at least two adjacent color filter portions 41 are the same. By setting the portions of the contour lines of the color filter portion 41 to be curved, the shape of the color filter portion 41 can be flexibly designed, so that the areas of the color filter portions 41 of various colors can be flexibly adjusted to optimize the dark state effect of the display substrate in the non-display state and the white balance effect of the display substrate.

[0090] As Figure 14 shown, the contour line of the color filter portion 43 is circular. The sections 424 of the contour lines of the respective color filter portions 42 are opposite to the contour line of the adjacent color filter portion 43, and each section 424 is an arc line; the sections 423 of the contour lines of the respective color filter portions 42 are opposite to the sections 445 of the contour line of the adjacent color filter portion 44, and the section 423 and the section 445 are both curves including two straight lines and one arc line.

[0091] In one embodiment, at least one of the color filter portions 41 is surrounded by a plurality of the color filter portions 41. The contour line of the surrounded color filter portion 41 is a smooth closed curve, and the portions of the contour lines of the plurality of color filter portions 41 that are opposite to the surrounded color filter portion 41 are located on the same smooth closed curve. Such an arrangement helps to reduce the gap between the color filter portion and each of the surrounding color filter portions, thereby effectively reducing the probability of the light-shielding layer 50 breaking.

[0092] Furthermore, the geometric center of the smooth closed curve where the portion of the contour line of the plurality of color filter portions that is opposite to the surrounded color filter portion is located is the first center, and the geometric center of the contour line of the surrounded color filter portion 41 is the second center. The first center coincides with the second center. Such an arrangement makes the gap between the surrounded color filter portion 41 and each of the surrounding color filter portions 41 relatively uniform, and can avoid the problem that the distance between the surrounded color filter portion 41 and a certain adjacent color filter portion 41 is too large, resulting in the light-shielding layer 50 breaking at this position.

[0093] As Figure 14 shown, the contour line of the color filter portion 43 is circular. Four color filter portions 42 and four color filter portions 44 surround the same color filter portion 43. The section 424 of the contour line of the four color filter portions 42 is opposite to the contour line of the color filter portion 43, and the section 444 of the contour line of the four color filter portions 44 is opposite to the contour line of the color filter portion 43. The four sections 424 and the four sections 444 are all arc lines and are on the same circle, and the center of this circle coincides with the center of the contour line of the color filter portion 43.

[0094] In one embodiment, at least two adjacent partial contour lines of the color filter portions 41 coincide. In this way, there is no gap between partial regions of the two adjacent color filter portions, and the problem that the light-shielding layer 50 breaks at this position can be effectively avoided. In some embodiments, there are a plurality of color filter portions 41 that have no gap with adjacent color filter portions 41.

[0095] In one embodiment, the maximum width of the gap between any two adjacent color filter portions 41 is less than or equal to 3 μm. When the maximum width of the gap between two adjacent color filter portions 41 is less than or equal to 3 μm, the light-shielding layer 50 will not break at this gap. The above arrangement can effectively avoid the problems of color separation and black dot defects when the display substrate displays caused by the breakage of the light-shielding layer. In some embodiments, the maximum width of the gap between any two adjacent color filter portions 41 is less than or equal to 1 μm.

[0096] In one embodiment, as Figures 2 to 8As shown, each of the plurality of color filter portions 41 in the color filter layer 40 includes a main body portion 411 and at least one protruding portion 412 connected to the main body portion 411; the protruding portion 412 is filled between the main body portions 411 of two adjacent color filter portions 41 in the same row; the protruding portion 412 is filled between the main body portions 411 of two adjacent color filter portions 41 in the same column. With such an arrangement, the gap between the main body portions 411 of two adjacent color filter portions 41 in the same row is small, and the gap between the main body portions 411 of two adjacent color filter portions 41 in the same column is small, thus effectively improving the problem of the large gap between two adjacent color filter portions 41 in the color filter layer 40, and further effectively improving the problem of the breakage of the light-shielding layer 50.

[0097] In one embodiment, the color filter layer includes at least three color filter portions of different colors; the protruding portions filled between any two adjacent main body portions are all protruding portions of the same color.

[0098] As Figure 2 shown, each of the first color filter portions 42 is provided with protruding portions 412 on opposite sides in the row direction X and opposite sides in the column direction Y respectively. In the color filter layer 40, the protruding portions 412 filled between the main body portions 411 of two adjacent color filter portions 41 in the same row and the protruding portions 412 filled between any two adjacent main body portions 411 in the same column are all the protruding portions of the first color filter portion 42. Other color filter portions except the first color filter portion 42 may all include main body portions. Specifically, the protruding portion 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 adjacent in the same row, and the protruding portion 412 of the first color filter portion 42 is filled between the main body portions 411 of two adjacent third color filter portions 44 in the same row; the protruding portion 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 adjacent in the same column, and the protruding portion 412 of the first color filter portion 42 is filled between the main body portions 411 of two adjacent third color filter portions 44 in the same column.

[0099] As Figure 3As shown, each of the second color filter portions 43 has protruding portions 412 provided on opposite sides in the row direction X and opposite sides in the column direction Y, respectively. In the color filter layer 40, the protruding portions 412 filled between the main body portions 411 of two adjacent color filter portions 41 in the same row and the protruding portions 412 filled between any two main body portions 411 adjacent in the same column are the protruding portions of the second color filter portion 43. Specifically, the protruding portion 412 of the second color filter portion 43 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 adjacent in the same row, and the protruding portion 412 of the second color filter portion 43 is filled between the main body portions 411 of two adjacent third color filter portions 44 in the same row; the protruding portion 412 of the second color filter portion 43 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 adjacent in the same column, and the protruding portion 412 of the second color filter portion 43 is filled between the main body portions 411 of two adjacent third color filter portions 44 in the same column.

[0100] As Figure 5 and Figure 8 shown, each of the third color filter portions 44 has protruding portions 412 provided on opposite sides in the row direction X and opposite sides in the column direction Y, respectively. In the color filter layer 40, the protruding portions 412 filled between the main body portions 411 of two adjacent color filter portions 41 in the same row and the protruding portions 412 filled between any two main body portions 411 adjacent in the same column are the protruding portions of the third color filter portion 44, and each third color filter portion 44 is an integral structure. Specifically, the protruding portion 412 of the third color filter portion 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 adjacent in the same row, and the protruding portion 412 of the third color filter portion 44 is filled between the main body portions 411 of two adjacent third color filter portions 44 in the same row; the protruding portion 412 of the third color filter portion 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 adjacent in the same column, and the protruding portion 412 of the third color filter portion 44 is filled between the main body portions 411 of two adjacent third color filter portions 44 in the same column. By setting all the third color filter portions 44 as an integral structure, there is no gap between adjacent third color filter portions 44, and the problem of the light-shielding layer breaking can be further improved.

[0101] In one embodiment, the color filter layer 40 includes color filter portions of at least three different colors; there are at least two adjacent color filter portions 41 with protrusions of two colors filled between the main bodies 411 thereof. By providing protrusions 412 of two colors filled between the main bodies 411 of two adjacent color filter portions 41, it helps to adjust the area sizes of these two color filter portions 41, and further helps to improve the dark state effect of the display substrate in the non-display state.

[0102] Further, as Figure 4 shown, protrusions 412 are respectively provided on opposite sides in the row direction X and on opposite sides in the column direction Y between the first color filter portion 42 and the second color filter portion 43; between the main bodies 411 of two color filter portions 41 in the same row, protrusions 412 of the first color filter portion 42 and protrusions 412 of the second color filter portion 43 are filled; between the main bodies 411 of two color filter portions 41 in the same column, protrusions 412 of the first color filter portion 42 and protrusions 412 of the second color filter portion 43 are filled. Figure 4 In the embodiment shown, between the main bodies 411 of the first color filter portion 42 and the second color filter portion 43 that are adjacent and in the same row, protrusions 412 of the first color filter portion 42 and protrusions 412 of the second color filter portion 43 are filled, and between the main bodies 411 of two adjacent third color filter portions 44 that are in the same row, protrusions 412 of the first color filter portion 42 and protrusions 412 of the second color filter portion 43 are filled; between the main bodies 411 of the first color filter portion 42 and the second color filter portion 43 that are adjacent and in the same column, protrusions 412 of the first color filter portion 42 and protrusions 412 of the second color filter portion 43 are filled, and between the main bodies 411 of two adjacent third color filter portions 44 that are in the same column, protrusions 412 of the first color filter portion 42 and protrusions 412 of the second color filter portion 43 are filled. With such a setting, it is more beneficial to the total area sizes of the first color filter portion 42 and the second color filter portion 43, and is beneficial to improving 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 areas of the main bodies of the first color filter portion 42 and the second color filter portion 43 are the same, and the areas of the protruding portions of the first color filter portion 42 and the second color filter portion 43 are the same. With such a setting, the difference between the total areas of the first color filter portion 42 and the second color filter portion 43 in the color filter layer 40 can be effectively reduced, and a better dark state effect of the display substrate in the non-display state can be achieved. In some embodiments, the shapes of the main bodies 411 of the first color filter portion 42 and the second color filter portion 43 are the same, and the shapes of the protruding portions 412 of the first color filter portion 42 and the second color filter portion 43 are the same.

[0104] In one embodiment, as Figure 6 and Figure 7 shown, at least one of the color filter portions 41 is provided with protruding portions 413 on opposite sides in the third direction Z1, and the third direction Z1 intersects both the row direction X and the column direction Y. With such a setting, the gap between the color filter portion 41 and the adjacent color filter portion 41 in the third direction Z1 is smaller, and the risk of the light-shielding layer 50 breaking can be further reduced. Figure 6 In the embodiment shown, among all the color filter portions 44 in the same row, half of the color filter portions 44 are provided with protruding portions 413 on opposite sides in the third direction Z1. Figure 7 In the embodiment shown, each color filter portion 43 is provided with protruding portions 413 on opposite sides in the third direction Z1.

[0105] In one embodiment, as Figure 6 and Figure 7 shown, at least one of the color filter portions 41 is provided with protruding portions 414 on opposite sides in the fourth direction Z2, the fourth direction Z2 intersects both the row direction X and the column direction Y, and is perpendicular to the third direction Z1. With such a setting, the gap between the color filter portion 41 and the adjacent color filter portion 41 in the fourth direction Z2 is smaller, and the risk of the light-shielding layer 50 breaking can be further reduced. Figure 6 In the embodiment shown, among all the color filter portions 44 in the same row, half of the color filter portions 44 are provided with protruding portions 414 on opposite sides in the fourth direction Z2. Figure 7 In the embodiment shown, each color filter portion 43 is provided with protruding portions 414 on opposite sides in the fourth direction Z2.

[0106] Preferably, as Figure 7 shown, each color filter portion 43 is provided with protruding portions 413 on opposite sides in the third direction Z1, and each color filter portion 43 is provided with protruding portions 414 on opposite sides in the fourth direction Z2.

[0107] In one embodiment, the distances from the surfaces of the respective color filter portions 41 in the color filter layer 40 away from the substrate 10 to the substrate 10 are all the same. With this arrangement, the surfaces of the respective color filter portions 41 away from the substrate 10 are in the same plane, which can avoid the risk of increasing the breakage of the light-shielding layer 50 due to the height difference between different color filter portions 41.

[0108] The embodiment of the present application also provides a display device. The display device includes the display substrate described in any one of the above embodiments.

[0109] In one embodiment, the display device further includes a driver and a power supply circuit. The driver is used to provide a driving signal for driving the sub-pixels to emit light, and the power supply circuit is used to supply power to the display substrate.
