[0075] In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of well-known functions and well-known components.

[0076] See also Figure 1A , Figure 1B , Figure 2A As shown, Figure 1A for Figure 1B Schematic diagram of the cross section at the dotted line EF, Figure 2A for Figure 1B An enlarged schematic diagram of a black matrix opening in FIG. 1 is a schematic diagram of an enlarged black matrix opening in FIG. 1 , wherein an embodiment of the present invention provides a display panel, comprising:

[0077] Substrate substrate 1; the substrate substrate 1 can specifically be a glass substrate, a silicon substrate or a flexible substrate, for example, it can be formed of a plastic material with excellent heat resistance and durability, such as polyimide (PI), polycarbonate (PC), polyethylene terephthalate (PET), polycarbonate, polyethylene, polyacrylate, polycarbonate, polyarylate, polyetherimide, polyethersulfone, polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), polysulfone (PSF), polymethyl methacrylate (PMMA), triacetyl cellulose (TAC), cycloolefin polymer (COP) and cycloolefin copolymer (COC), etc.

[0078] The light-emitting layer 2 is located on one side of the base substrate 1 and has a plurality of light-emitting parts 20; specifically, the light-emitting parts 20 may include a first type of light-emitting part 21, a second type of light-emitting part 22, and a third type of light-emitting part 23; the first type of light-emitting part 21 may specifically be a light-emitting part emitting blue light, and the specific material may be an organic light-emitting material emitting blue light; the second type of light-emitting part 22 may specifically be a light-emitting part emitting red light, and the specific material may be an organic light-emitting material emitting red light; the third type of light-emitting part 23 may specifically be a light-emitting part emitting green light, and the specific material may be an organic light-emitting material emitting green light;

[0079] The encapsulation layer 3 is located on the side of the light-emitting layer 2 away from the substrate 1; the encapsulation layer 3 may be a thin film encapsulation layer, and may specifically include a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer stacked in sequence;

[0080] The black matrix layer 4 is located on the side of the encapsulation layer 3 away from the light-emitting layer 2, and has a black matrix opening 40 in the area corresponding to the light-emitting portion 20. The main shape of the black matrix opening 40 (such as Figure 2AThe black matrix layer 4 is a polygon, and at least the corner position 45 of the polygon is an arc-shaped curve to achieve a transition connection between the edges 46 of the polygon; specifically, the black matrix layer 4 except the black matrix opening 40 is a black matrix body, that is, the area outside the black matrix opening 40 can be a black matrix body 44; it can be understood that the main shape of the black matrix opening 40 can be specifically understood as the main outline of the black matrix opening 40, and the specific edges 46 can be non-linear line segments, but the overall shape is still polygonal. For example, the main shape of the black matrix opening 40 can be a rectangle, but the four edges of the rectangle can be arc-shaped. Of course, each edge can also be a straight line; the black matrix opening 40 corresponds to the light-emitting portion 20. Specifically, it can be understood that the positive projection of the black matrix opening 40 on the base substrate 1 covers the positive projection of the light-emitting portion 20 on the base substrate 1, and the black matrix layer 4 is opened correspondingly at the position where each light-emitting portion 20 is located, forming a black matrix opening 40 corresponding to the light-emitting portion 20, so as to realize that the light emitted by the light-emitting portion 20 is emitted through the black matrix opening 40; combined with Figure 1A and Figure 1B As shown, the black matrix openings 40 may specifically include first-type black matrix openings 41 corresponding to the first-type light-emitting portions 21, second-type black matrix openings 42 corresponding to the second-type light-emitting portions 22, and third-type black matrix openings 43 corresponding to the third-type light-emitting portions 23. The main body shape of the first-type black matrix openings 41 may be consistent with the shape of the first-type light-emitting portions 21, for example, both may be hexagonal; the main body shape of the second-type black matrix openings 42 may be consistent with the shape of the second-type light-emitting portions 22, and the main body shape of the third-type black matrix openings 43 may be consistent with the shape of the third-type light-emitting portions 23;

[0081] The color filter layer 5 is located on a side of the black matrix layer 4 that is away from the encapsulation layer 3 , and has a color resist portion 50 in an area corresponding to the black matrix opening 40 . Specifically, since the color resist portion 50 is arranged at a position corresponding to the black matrix opening 40 of the black matrix layer 4, and the black matrix opening 40 corresponds to the light-emitting portion 20, and thus, the position of the color resist portion 50 also corresponds to the position of the light-emitting portion 20, specifically, the color resist portion 50 may include a first color resist portion 51 corresponding to the first light-emitting portion 21, a second color resist portion 52 corresponding to the second light-emitting portion 22, and a third color resist portion 53 corresponding to the third light-emitting portion 23. If the first light-emitting portion 21 is a light-emitting portion that emits blue light, then the first color resist portion 51 may be a blue color resist portion that transmits blue light and blocks other light colors from passing through. If the second light-emitting portion 22 is a light-emitting portion that emits red light, then the second color resist portion 52 may be a red color resist portion that transmits red light and blocks other light colors from passing through. If the third light-emitting portion 23 is a light-emitting portion that emits green light, then the third color resist portion 53 may be a green color resist portion that transmits green light and blocks other light colors from passing through.

[0082] In the embodiment of the present disclosure, the main shape of the black matrix opening 40 is a polygon, and the black matrix opening 40 is an arc-shaped curve at least at the corner position 45 of the polygon to achieve an arc-shaped transition connection between the edges 46 of the polygon. Compared with the black matrix openings in conventional display panels having sharp-angled closing at the corner positions, the arc-shaped corner design in the embodiment of the present disclosure can reduce the size mutation at the sharp corners and reduce the diffraction effect of the reflected light generated by the external ambient light after passing through the display panel, thereby reducing the color separation phenomenon.

[0083] It can be understood that the display panel in the embodiment of the present disclosure may not include a circular polarizer. By using the color film layer 5 and the black matrix layer 4 as provided in the embodiment of the present disclosure, at the position where display is required, that is, the position where the light-emitting part 20 is located, the light emitted by the light-emitting part 20 is emitted through the black matrix opening 40, and does not affect the display; and for the position other than the light-emitting part 20, it can be blocked by the black matrix body 44, and the external ambient light cannot enter, thereby playing the role of the circular polarizer to prevent the reflection of external light.

[0084] It should be noted that color separation refers to the phenomenon that when the screen is off and the reflected light is illuminated by ambient light (such as point light source or line light source), the color (red, green and blue) separation of the reflected light occurs. Figure 1A As shown, under ambient light, light passes through the color filter layer 5 and becomes monochromatic light, and enters the metal film layer (such as the anode layer and / or cathode layer, Figure 1A The monochromatic reflected light is then reflected by the metal film layer and passes through the black matrix opening 40. Since the black matrix opening 40 is relatively small (eg, the black matrix opening is λ*10 2 When the black matrix opening 40 is in the order of magnitude, where λ is the wavelength of the reflected light, the screen will inevitably produce diffraction effects of monochromatic light (R, G, B) under ambient light (especially point light source). These diffraction effects further increase the degree of color separation.

[0085] In specific implementation, combined with Fig. 13B As shown, the main shape of the first type of black matrix opening 41, the main shape of the second type of black matrix opening 42, and the main shape of the third type of black matrix opening 43 can all be circular. In the embodiment of the present disclosure, the main shape of the black matrix opening is circular. Compared with the black matrix opening in the conventional display panel having a sharp-angled closing at the corner position, the main shape of the black matrix opening in the embodiment of the present disclosure is circular, which can reduce the size mutation at the sharp corner, reduce the diffraction effect of the reflected light generated by the external ambient light after passing through the display panel, and thus reduce the color separation phenomenon.

[0086] In specific implementation, combined with Fig. 13B As shown, the orthographic projection of a third type black matrix opening 43 on the base substrate 1 covers the orthographic projections of two third type light-emitting portions 23 on the base substrate 1 , and the two third type light-emitting portions 23 covered by the third type black matrix opening 43 are light-emitting portions emitting green light.

[0087] In specific implementation, combined with Fig. 13B As shown, the orthographic projection of a first-type black matrix opening 41 on the base substrate 1 covers the orthographic projection of a first-type light-emitting portion 21 on the base substrate 1, and the orthographic projection of a second-type black matrix opening 42 on the base substrate 1 covers the orthographic projection of a second-type light-emitting portion 22 on the base substrate 1; wherein the first-type light-emitting portion 21 covered by the first-type black matrix opening 41 is a light-emitting portion that emits blue light, and the second-type light-emitting portion 22 covered by the second-type black matrix opening 42 is a light-emitting portion that emits red light.

[0088] In specific implementation, combined with Figure 1A As shown, there is a pixel definition layer 7 between the base substrate 1 and the light-emitting layer 2, the pixel definition layer 7 has a plurality of pixel definition openings 70, the light-emitting portion 20 is located in the pixel definition openings 70, and the shape of the light-emitting portion 20 is consistent with the shape of the pixel definition openings 70. It can be understood that in the manufacturing process of the display panel, the pixel definition layer 7 with the pixel definition openings 70 is first formed, and then the light-emitting portion 20 is formed in the pixel definition openings 70, so that the shape of the light-emitting portion 20 is consistent with the shape of the pixel definition layer openings 70. It can be understood that the light-emitting portion 20 can specifically be the position occupied by the light-emitting area of ​​the display panel during the display process, that is, in a specific implementation, for each sub-pixel, the light-emitting material formed at the position where the pixel definition opening is located may be larger than the area occupied by the pixel definition opening, but the light-emitting area is determined by the area of ​​the light-emitting material at the energized position, that is, the light-emitting portion 20 is determined by the size of the area where the light-emitting material contacts the anode.

[0089] In the specific implementation, see Figure 2A-2C As shown, the black matrix opening 40 at the corner position 45 is an arc that bulges toward the side away from the center O of the black matrix opening 40. Specifically, the black matrix opening 40 at the corner position 45 is an arc that bulges toward the side away from the center O of the black matrix opening 40 with the corner point O' as the center, and the corner point O' is the intersection of the extension lines of the adjacent edges 46. For example, Figure 2A As shown, the main body shape of the black matrix opening 40 is a hexagon, having six edges 46, and two adjacent edges 46 intersect each other to form six corner positions 45, each corner position 45 has a corner point O', and a non-closed arc (i.e., an outward convex arc) with the corner point O' as the center can be set at the corner position 45 to bulge away from the center of the black matrix opening 40, thereby realizing an arc-shaped transition between adjacent edges 46 at the corner position 45; or, see Figure 2B As shown, the main body shape of the black matrix opening 40 is a quadrilateral with four edges 46. Two adjacent edges 46 intersect each other to form four corner positions 45. Each corner position 45 has a corner point O'. For the corner position 45, a non-closed arc (i.e., an outward convex arc) with the corner point O' as the center can be set to bulge away from the center O of the black matrix opening, thereby realizing an arc-shaped transition between adjacent edges 46 at the corner position 45; or, see Figure 2C As shown, the main body shape of the black matrix opening 40 is a pentagon with five edges 46. Two adjacent edges 46 intersect each other to form five corner positions 45. Each corner position 45 has a corner point O'. For the corner position 45, a non-closed arc (i.e., an outward convex arc) with the corner point O' as the center can be set to bulge toward the side away from the center O of the black matrix opening 40, thereby realizing an arc-shaped transition between adjacent edges at the corner position 45.

[0090] In a specific implementation, the black matrix opening 40 at the corner position 45 is an arc that is concave toward the center O of the black matrix opening 40. Specifically, the black matrix opening 40 at the corner position 45 is an arc that is concave toward the center O of the black matrix opening 40 with the corner point O' as the center, and the corner point O' is the intersection of the extension lines of the adjacent edges 46. For example, Figure 3A As shown, the main body shape of the black matrix opening 40 is a hexagon, having six edges 46, and two adjacent edges 46 intersect each other to form six corner positions 45, each corner position 46 has a corner point O', and a non-closed arc (i.e., an inward concave arc) with the corner point O' as the center can be set at the corner position 45, thereby realizing an arc-shaped transition between adjacent edges at the corner position 45; or, see Figure 3B As shown, the main body shape of the black matrix opening 40 is a quadrilateral with four edges 46. Two adjacent edges 46 intersect each other to form four corner positions 45. Each corner position 45 has a corner point O'. For the corner position 45, a non-closed arc (i.e., an inward concave arc) with the corner point O' as the center can be set to the corner position 45, which is concave toward the side of the center O of the black matrix opening 40, so as to achieve an arc-shaped transition between adjacent edges 46 at the corner position 45; or, see Figure 3C As shown, the main body shape of the black matrix opening 40 is a pentagon with five edges 46. Two adjacent edges 46 intersect each other to form five corner positions 45. Each corner position 45 has a corner point O'. For the corner position 45, a non-closed arc (i.e., an inwardly concave arc) with the corner point O' as the center can be set to the side concave toward the center O of the black matrix opening 40, so as to achieve an arc-shaped transition between adjacent edges 46 at the corner position 45.

[0091] In a specific implementation, the main shape of the black matrix opening 40 is a quadrilateral, a pentagon, or a hexagon; the radius of the arc is one fifth to one half of the length of the minimum edge 46 of the black matrix opening 40. Figure 2A As shown, the main body shape of the black matrix opening 40 is a hexagon, and the hexagon has two first-type edges 461 that are oppositely arranged and parallel, second-type edges 462 that are respectively connected to the first end of each first-type edge 461, and third-type edges 463 that are respectively connected to the second end of the first-type edge 461, wherein the extension length of the first-type edge 461 is greater than the extension length of the second-type edge 462, and also greater than the extension length of the third-type edge 463, and the extension length of the second-type edge 462 is the same as the extension length of the third-type edge 462. Then, in the hexagon, the arc radius at the corner position 45 can be one-fifth to one-half of the length of the second-type edge 462; for example, combined with Figure 2B As shown, the main body shape of the black matrix opening 40 is a quadrilateral, which has two fourth-type edges 464 that are arranged oppositely and in parallel, and fifth-type edges 465 that respectively connect the corresponding ends of the two fourth-type edges 464, wherein the extension length of the fourth-type edge 464 is greater than the extension length of the fifth-type edge 465. Then, in the quadrilateral, the arc radius at the corner position 45 can be one-fifth to one-half of the length of the fifth-type edge 465; for example, combined with Figure 2C As shown, the main body shape of the black matrix opening 40 is a pentagon, which has two oppositely arranged and parallel sixth-type edges 466, a seventh-type edge 467 connected to the first end of each sixth-type edge 466, and an eighth-type edge 468 connecting the two second ends of the two sixth-type edges 466, wherein the extension length of the sixth-type edge 466 is less than the extension length of the seventh-type edge 467, and the length of the seventh-type edge 467 is less than the length of the eighth-type edge 468. Then, in the pentagon, the radius of the arc at the corner position 45 can be one-fifth to one-half of the length of the sixth-type edge 466. In the disclosed embodiment, the radius of the arc is one-fifth to three-fifths of the minimum edge length of the black matrix opening.

[0092] In a specific implementation, except for the corner position 45, the edge 46 of the black matrix opening 40 is a straight line. Figure 2A As shown, the main body of the black matrix opening 40 is a hexagon, the corner position 45 is an arc convex outward, and each edge 46 is a straight line; see Figure 3A As shown, the main body of the black matrix opening 40 is a hexagon, the corner position 45 is an inwardly concave arc, and each edge 46 is a straight line; for example, see Figure 2BAs shown, the main body of the black matrix opening 40 is a quadrilateral, the corner position 45 is an arc convex outward, and each edge 46 is a straight line; see Figure 3B As shown, the main body of the black matrix opening 40 is a quadrilateral, the corner position 45 is an inwardly concave arc, and each edge 46 is a straight line; for example, see Figure 2C As shown, the main body of the black matrix opening 40 is a pentagon, the corner position 45 is an arc convex outward, and each edge 46 is a straight line; see Figure 3C As shown, the main body of the black matrix opening 40 is a pentagon, the corner position 45 is an inwardly concave arc, and each edge 46 is a straight line.

[0093] In a specific implementation, except for the corner position 45, the edge 46 of the black matrix opening 40 is an arc segment that bulges away from the center O of the black matrix opening 40, that is, the edge 46 is an arc segment that bulges outward. Figure 4A As shown, the main body of the black matrix opening 40 is a hexagon, the corner position 45 is an arc convex outward, and each edge 46 is an arc segment convex outward; see Figure 4B As shown, the main body of the black matrix opening 40 is a hexagon, the corner position 45 is an inwardly concave arc, and each edge 46 is an outwardly convex arc segment; for example, see Figure 5A As shown, the main body of the black matrix opening 40 is a quadrilateral, the corner position 45 is an arc convex outward, and each edge 46 is an arc segment convex outward; see Figure 5B As shown, the main body of the black matrix opening 40 is a quadrilateral, the corner position 45 is an inwardly concave arc, and each edge 46 is an outwardly convex arc segment; for example, see Fig. 6A As shown, the main body of the black matrix opening 40 is a pentagon, the corner position 45 is an arc convex outward, and each edge 46 is an arc segment convex outward; see Figure 6B As shown, the main body shape of the black matrix opening 40 is a pentagon, the corner position 45 is an inwardly concave arc, and each edge 46 is an outwardly convex arc segment.

[0094] In a specific implementation, except for the corner position 45, the edge 46 of the black matrix opening 40 is an arc segment that is concave toward the center O of the black matrix opening 40, that is, the edge 46 is an arc segment that is concave inward. Fig. 7A As shown, the main body of the black matrix opening 40 is a hexagon, the corner position 45 is an outwardly convex arc, and each edge 46 is an inwardly concave arc segment; see Figure 7B As shown, the main body of the black matrix opening 40 is a hexagon, the corner position 45 is an inwardly concave arc, and each edge 46 is an inwardly concave arc segment; for example, see Fig. 8AAs shown, the main body of the black matrix opening 40 is a quadrilateral, the corner position 45 is an outwardly convex arc, and each edge 46 is an inwardly concave arc segment; see Figure 8B As shown, the main body of the black matrix opening 40 is a quadrilateral, the corner position 45 is an inwardly concave arc, and each edge 46 is an inwardly concave arc segment; for example, see Fig. 9A As shown, the main body of the black matrix opening 40 is a pentagon, the corner position 45 is an outwardly convex arc, and each edge 46 is an inwardly concave arc segment; see Fig. 9B As shown, the main body shape of the black matrix opening 40 is a pentagon, the corner position 45 is an inwardly concave arc, and each edge 46 is an inwardly concave arc segment.

[0095] In a specific implementation, the arc of the corner position 45 is directly connected to the arc segment of the edge 46. Figure 7B As shown, the main body of the black matrix opening 40 is a hexagon, the corner position 45 is an inwardly concave arc, each edge 46 is an inwardly concave arc segment, and the arc segment at the edge 46 is directly connected to the arc at the corner position 45; for example, see Figure 8B As shown, the main body shape of the black matrix opening 40 is a quadrilateral, the corner position 45 is an inwardly concave arc, each edge 46 is an inwardly concave arc segment, and the arc segment at the edge 46 is directly connected to the arc at the corner position 45.

[0096] It should be noted that Figure 1B The main body shape of each black matrix opening is only a hexagon, the corner position 45 is a convex arc, and the edge 46 is a straight line. The present invention is not limited to this. In a specific implementation, the main body shape of the black matrix opening 40 at different positions can be different. The shape of the corner position 45 of the black matrix opening 40 at different positions and the shape of the edge can be as follows: Figure 2A-Figure 9B In addition, in the embodiment of the present disclosure, the arc at the corner position may also be other arcs with the corner point as the center, that is, the center may not be located at the corner point, and the present invention is not limited to this.

[0097] In specific implementation, combined with Figure 1BAs shown, the orthographic projection of the black matrix opening 40 on the base substrate 1 covers the orthographic projection of the light-emitting portion 20 on the base substrate 1. That is, the black matrix opening 40 is larger than the light-emitting portion 20, thereby avoiding the influence of the black matrix body on the light-emitting condition of the light-emitting portion 20. It can be understood that the orthographic projection of the black matrix opening 40 of the present disclosure on the base substrate 1 covers the orthographic projection of the light-emitting portion 20 on the base substrate 1, which can be based on the fact that the black matrix opening 40 has been designed as an arc convex outward or concave inward at the corner position 45, and the edge 46 is designed as an arc segment convex outward or concave inward, that is, after the black matrix opening 40 in the embodiment of the present disclosure is improved, its orthographic projection on the base substrate 1 still covers the orthographic projection of the light-emitting portion 20 on the base substrate 1.

[0098] In a specific implementation, the shape of the light emitting portion 20 is similar to the main shape of the black matrix opening 40. For example, see Fig. 10A As shown, the main shape of the black matrix opening 40 is hexagonal, and the corresponding shape of the light-emitting portion 20 is also hexagonal; for example, see Fig. 10B As shown, the main shape of the black matrix opening is a quadrilateral, and the corresponding shape of the light-emitting portion is also a quadrilateral; for example, see Fig. 10C As shown, the main body shape of the black matrix opening 40 is a pentagon, and the corresponding shape of the light-emitting portion 20 is also a pentagon.

[0099] In a specific implementation, the center of the black matrix opening 40 overlaps with the center of the light-emitting portion 20. Of course, it is understandable that in actual manufacturing, due to limited process precision, it is difficult to make the center of the black matrix opening 40 completely and accurately overlap with the center of the light-emitting portion 20. Therefore, in the embodiment of the present disclosure, the center of the black matrix opening 40 overlaps with the center of the light-emitting portion 20, which can be understood as the approximate overlap of the centers of the two.

[0100] In a specific implementation, the main shape of the black matrix opening 40 is 2 micrometers to 6 micrometers outside the shape of the light-emitting portion 20. Fig. 10A As shown, the main shape of the black matrix opening 40 is a hexagon, and the shape of the light-emitting portion 20 is also a hexagon. The two shapes are similar and the centers overlap. The main shape of the black matrix opening 40 is equivalent to the shape of the light-emitting portion 20, and each boundary of the light-emitting portion 20 is perpendicular to the boundary (such as Fig. 10A The outward movement distance (as shown by the dotted arrow in FIG. 1 ) is h, and h can specifically be 2 microns to 6 microns.

[0101] In the specific implementation, see Fig.11A and Fig. 11BAs shown, there is a touch layer 8 between the encapsulation layer 3 and the black matrix layer 4; the touch layer 8 includes a first insulating layer 81, a first metal layer 82, a second insulating layer 83, a second metal layer 84, and a third insulating layer 85 which are sequentially located on one side of the encapsulation layer 3; the second metal layer 84 includes a plurality of first touch electrodes 841 extending along the first direction AB, and a plurality of second touch electrodes 842 extending along the second direction CD; the first touch electrodes 841 and the second touch electrodes 842 are cross-insulated; each first touch electrode 841 includes a plurality of first sub-touch electrode blocks 8411 connected to each other, and each second touch electrode 842 includes a plurality of second sub-touch electrode blocks 8421 spaced apart from each other; the first metal layer 82 includes a plurality of bridging electrodes 820, and each second sub-touch electrode block 8421 in the same second direction CD is electrically connected via the bridging electrode 820.

[0102] In specific implementation, combined with Fig.12 As shown, the first sub-touch electrode block 8411, the second sub-touch electrode block 8421, and the bridge electrode 820 all have meshes (such as Fig.12 The orthographic projection of the mesh on the base substrate 1 covers the orthographic projection of the light-emitting portion 20 on the base substrate 1. That is, the first sub-touch electrode block 8411, the second sub-touch electrode block 8421, and the bridge electrode 820 can be specifically a structure with multiple meshes formed by metal lines 840. It can be understood that since the accuracy of pixels is relatively high compared to the accuracy of touch control, the areas of the first sub-touch electrode block 8411 and the second sub-touch electrode block 8421 are much larger than the light-emitting portion 20, therefore, Fig.12 The first sub-touch electrode block 8411, the second sub-touch electrode block 8421, and the bridge electrode 820 are enlarged to show the corresponding relationship with the light-emitting portion 20, that is, the overall schematic diagram of the first sub-touch electrode block 8411, the second sub-touch electrode block 8421, and the bridge electrode 820 is as shown in FIG. Fig. 11B As shown, its enlarged corresponding relationship with the light emitting portion 20 is as follows Fig.12 The spacing between the first sub-touch electrode block 8411 and the second sub-touch electrode block 8421 in the same layer can be formed by breaking the metal line 840 at the corresponding position.

[0103] In specific implementation, combined with Fig.12 As shown, the mesh may include a first type of mesh, a second type of mesh and a third type of mesh, the orthographic projection of the third type of mesh on the substrate substrate 1 may cover the orthographic projection of two third type of light-emitting portions 23 on the substrate substrate 1, the orthographic projection of the first type of mesh on the substrate substrate 1 may cover the orthographic projection of one first type of light-emitting portion 21 on the substrate substrate 1, and the orthographic projection of the second type of mesh on the substrate substrate 1 may cover the orthographic projection of one second type of light-emitting portion 22 on the substrate substrate 1.

[0105] In specific implementation, combined with Fig.11A As shown, the side of the color filter layer 5 facing away from the black matrix layer 4 has a protective layer 9. The protective layer 9 can be specifically an optical adhesive layer to protect the color resistance part 50 of the color filter layer 5 and the black matrix layer 4. An anode layer 61 can also be provided between the pixel defining layer 7 and the base substrate 1, and the anode layer 61 can specifically include a first type of anode 611 corresponding to the first type of light-emitting part 21, a second type of anode 612 corresponding to the second type of light-emitting part 22, and a third type of anode 613 corresponding to the third type of light-emitting part 23. A cathode layer 62 can also be provided between the light-emitting layer 2 and the encapsulation layer 3, and the cathode layer 62 can specifically be a whole layer structure.

[0106] In a specific implementation, the side of the protective layer 9 facing away from the color filter layer 5 has a cover plate (not shown in the figure) or a covering film layer (not shown in the figure). The cover plate can be a glass cover plate.

[0108] Step 1: providing a mask plate corresponding to the black matrix opening pattern of the embodiment of the present disclosure;

[0109] Step 2: forming an anode layer, a pixel definition layer, a light emitting layer, a cathode layer, a packaging layer, and a touch layer in sequence on one side of the substrate;
