[0043] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0044] The embodiment of the present application provides a display panel that can solve the problem of low pixel aperture ratio due to low screen space utilization of the display panel. Figure 1 and Figure 2 , Figure 1 is a top view of a display panel provided in an embodiment of the present application, Figure 2 yes Figure 1 The schematic diagram of the film structure of the display panel at AA' is shown, wherein: Figure 2 The dotted frame in FIG. 3 is used to identify the first light emitting portion 301. The display panel 000 may include: a driving backplane 100, a pixel definition layer 200 and a light emitting layer 300.

[0045] The pixel definition layer 200 may be located on one side of the driving backplane 100. The pixel definition layer 200 may define a plurality of pixel regions on the driving backplane 100, as well as a non-pixel region located between adjacent pixel regions, and the non-pixel region is arranged around the corresponding pixel region. The pixel definition layer 200 may have a plurality of pixel openings U. The pixel region defined by the pixel definition layer 200 on the driving backplane 100 refers to: the region where the pixel opening U is located; the non-pixel region defined by the pixel definition layer 200 on the driving backplane 100 refers to: the region around which the pixel opening U is distributed.

[0046] The light-emitting layer 300 can be located on a side of the pixel definition layer 200 away from the driving backplane 100. The light-emitting layer 300 may include multiple light-emitting portions, which correspond one-to-one to multiple pixel openings U, and the light-emitting portions are located in the corresponding pixel openings U, that is, the light-emitting portions are located in the pixel area.

[0047] The display panel 000 may further include a first electrode 400 and a second electrode 500. The first electrode 400 may be an anode, and the second electrode 500 may be a cathode. The first electrode 400 may be located on a side of the pixel definition layer 200 close to the driving backplane 100, and the number of the first electrodes 400 may be multiple, and the multiple first electrodes 400 may correspond to the multiple pixel openings U one by one, that is, the multiple first electrodes 400 may correspond to the multiple light-emitting portions one by one. The orthographic projection of the pixel opening U on the driving backplane 100 may be located within the orthographic projection of the corresponding first electrode 400 on the driving backplane 100, and the light-emitting portion located in the pixel opening U may contact the first electrode 400. The second electrode 500 is located on a side of the light-emitting layer 300 away from the driving backplane 100, that is, the light-emitting portion may contact the second electrode 500. In other words, the light-emitting portion located in the pixel opening U may contact the first electrode 400 and the second electrode 500 at the same time. When corresponding voltages are applied to the first electrode 400 and the second electrode 500 , the plurality of light emitting portions therebetween can emit light of different colors, and the light is mixed and superimposed, so that the display panel 000 can present a corresponding display image.

[0048] The plurality of light emitting portions may include a plurality of first light emitting portions 301 , a plurality of second light emitting portions 302 and a plurality of third light emitting portions 303 , and the light emitting colors of the first light emitting portions 301 , the second light emitting portions 302 and the third light emitting portions 303 may be different.

[0049] Please refer to Figure 1 , the two second light-emitting units 302 can be respectively located on both sides of the same first light-emitting unit 301 in the first direction X, the third light-emitting unit 303 can be located on one side of the first light-emitting unit 301 in the second direction Y, and the third light-emitting unit 303 can also be located on one side of the two second light-emitting units 302 in the second direction Y. Among them, the first direction X can intersect with the second direction Y. For example, the first direction X can be perpendicular to the second direction Y, and the first direction X and the second direction Y can be parallel to the driving backplane 100. It should be noted that the embodiment of the present application is schematically described by taking the first direction X as the longitudinal direction and the second direction Y as the lateral direction as an example. In other implementations, please refer to Figure 5 , the first direction X may also be the horizontal direction, and the second direction Y may also be the vertical direction. This embodiment of the present application does not limit this.

[0050] In this way, the adjacently distributed first light emitting portion 301 , the second light emitting portion 302 and the third light emitting portion 303 can emit light of different colors, and after the light is mixed, the display panel 000 can display the corresponding picture.

[0051] The orthographic projection of the first light-emitting portion 301 on the driving backplane 100 may have two first divisions K, and the two first divisions K may be relatively arranged on both sides of the orthographic projection in the first direction X, and a second light-emitting portion 302 is respectively arranged on both sides of the first light-emitting portion 301 in the first direction X, and the two second light-emitting portions 302 may correspond one-to-one to the two first divisions K.

[0052] The orthographic projection of the second light-emitting portion 302 on the driving backplane 100 may have a second subdivision M, and the second subdivision M may correspond to the first subdivision K one by one. One of the first subdivision K and the second subdivision M may be a concave area, and the other may be a convex portion. In one possible implementation, the convex portion may be entirely located in the concave area; in another possible implementation, a portion of the convex portion may be located in the concave area, and another portion may be located outside the concave area. This embodiment of the present application does not limit this.

[0053] In this way, the first light-emitting portion 301 and the two adjacently distributed second light-emitting portions 302 can achieve concave-convex matching through the first division K and the second division M, so that the multiple light-emitting portions can be arranged more closely, thereby improving the screen space utilization rate of the display panel 000, and further enabling the display panel 000 to arrange more light-emitting portions, thereby increasing the light-emitting area and improving the pixel opening ratio.

[0054] In summary, the embodiment of the present application provides a display panel, and the two second light-emitting parts can be respectively located on both sides of the same first light-emitting part in the first direction, and the orthographic projection of the first light-emitting part on the driving backplane has two first divisions arranged opposite to each other in the first direction, and the orthographic projection of the second light-emitting part on the driving backplane has a second division corresponding to the first division. One of the first division and the second division can be a concave area, and the other can be a convex part. The convex part can be located at least in the concave area, that is, the first division and the second division can achieve concave-convex matching. In this way, a close arrangement can be achieved between the first light-emitting part and the two adjacently distributed second light-emitting parts. In this way, the space of the display panel can be reasonably utilized, and the screen space utilization rate of the display panel can be improved, so that the display panel can be arranged with more light-emitting parts, thereby increasing the light-emitting area and improving the aperture ratio of the display panel.

[0055] Please refer to Figure 3 , Figure 3The dotted box in the figure is used to identify the thin film transistor 104. The driving backplane 100 of the display panel 000 may include: a substrate 101, and a buffer layer 102, a gate insulating layer 103, a thin film transistor 104, an interlayer dielectric layer 105, a conductive layer 106, a second planar layer 107, and a first planar layer 108 stacked on the substrate 101 in a direction vertically and away from the substrate 101.

[0056] The driving backplane 100 may include a plurality of thin film transistors 104. The thin film transistor 104 may include a gate 1041, a source 1042, a drain 1043 and an active layer pattern 1044. One of the source 1042 and the drain 1043 may be electrically connected to a data line, and the other of the source 1042 and the drain 1043 may be electrically connected to a conductive layer 106. The conductive layer 106 may be electrically connected to a first electrode 400, so that the source 1042 or the drain 1043 may be electrically connected to the first electrode 400, thereby achieving electrical connection between the thin film transistor 104 and the first electrode 400. In the embodiment of the present application, the drain 1043 may be electrically connected to the data line, and the source 1042 may be electrically connected to the conductive layer 106.

[0057] There may be multiple first electrodes 400, and multiple thin film transistors 104 may correspond to the multiple first electrodes 400 one by one, and be electrically connected together through the conductive layer 106. The multiple first electrodes 400 may also be connected to the multiple light-emitting portions one by one, that is, the multiple thin film transistors 104 may correspond to the multiple light-emitting portions one by one. In this way, the multiple thin film transistors 104 may be used to drive the corresponding first electrodes 400, so that under the action of the first electrode 400 and the second electrode 500, the light-emitting portion located between the two emits light, so that the display panel 000 displays the corresponding picture.

[0058] It should be noted that the luminous color of the first light-emitting unit 301 may be blue, the luminous color of the second light-emitting unit 302 may be one of red and green, and the luminous color of the third light-emitting unit 303 may be the other of red and green. Since the life of the light-emitting unit emitting blue light is short, the luminous efficiency of the blue light will be greatly attenuated after working for a long time. The display screen is usually presented by mixing and superimposing the light of different colors emitted by the light-emitting unit. After the luminous efficiency of the blue light is attenuated, the display screen may have a color cast, which brings a poor user experience.

[0059] To this end, in the display panel 000 provided in the embodiment of the present application, the area of ​​the orthographic projection of the first light-emitting portion 301 on the driving backplane 100 can be larger than the area of ​​the orthographic projection of the second light-emitting portion 302 on the driving backplane 100, and can be larger than the area of ​​the orthographic projection of the third light-emitting portion 303 on the driving backplane. In this way, for the adjacently distributed third light-emitting portion 303, the first light-emitting portion 301, and the two second light-emitting portions 302 located on both sides of the first light-emitting portion 301, it can be ensured that the area of ​​the orthographic projection of the first light-emitting portion 301 on the driving backplane 100 is larger, thereby improving the luminous efficiency of blue light.

[0060] Exemplarily, the area of ​​the orthographic projection of the first light-emitting portion 301 on the driving backplane 100 may be greater than or equal to the sum of the areas of the orthographic projections of the two second light-emitting portions 302 distributed on both sides of the first light-emitting portion 301 in the first direction X on the driving backplane 100. In this way, it can be further ensured that the area of ​​the orthographic projection of the first light-emitting portion 301 on the driving backplane 100 is larger, the luminous efficiency of the blue light is improved, and the luminous efficiency of the blue light is kept as balanced as possible with the luminous efficiency of the red light and the green light, thereby reducing the color cast of the display screen and improving the user experience.

[0061] It should be noted that the multiple light-emitting parts in the light-emitting layer 300 can be formed by evaporation using a fine metal mask. The fine metal mask contains multiple evaporation openings. After the evaporation material is attached to the driving backplane 100 through these evaporation openings, multiple light-emitting parts can be formed on the driving backplane 100. Because there is a certain distance between two adjacent openings in the fine metal mask, there is also a certain distance between two adjacent light-emitting parts in the multiple light-emitting parts formed on the driving backplane 100.

[0062] For example, please refer to Figure 4 , the distance between the first light-emitting portion 301 and the adjacent second light-emitting portion 302 is a, the distance between the first light-emitting portion 301 and the adjacent third light-emitting portion 303 is b, and the distance between the second light-emitting portion 302 and the adjacent third light-emitting portion 303 is c. When the distance between two adjacent light-emitting portions is too large, it may result in a smaller number of light-emitting portions that can be arranged in the display panel 000, resulting in a lower pixel aperture ratio. Optionally, the distance between two adjacent light-emitting portions can be between 16 microns and 20 microns, preferably 18 microns, that is, a, b, and c can all be 18 microns. In this way, the space of the display panel 000 can be reasonably utilized to arrange a larger number of light-emitting portions, thereby improving the pixel aperture ratio.

[0063] exist Figure 4In the figure, two second light-emitting portions 302 are arranged between two adjacent first light-emitting portions 301 in the first direction X. For the two second light-emitting portions 302, one second light-emitting portion 302 can be located on the side of the first first light-emitting portion 302 close to the second first light-emitting portion 301, and the other second light-emitting portion 302 can be located on the side of the second first light-emitting portion 301 close to the first first light-emitting portion 301. During evaporation, the same evaporation opening in the fine metal mask can be used to simultaneously form the two second light-emitting portions 302. In this way, the distance between the two second light-emitting portions 302 can be reduced, so that there is space to arrange more light-emitting portions, thereby improving the pixel aperture ratio.

[0064] It should be noted that the light-emitting layer 300 may also include a plurality of non-light-emitting portions, and the plurality of non-light-emitting portions may correspond one-to-one to the plurality of light-emitting portions. The non-light-emitting portions may be arranged around the corresponding light-emitting portions and may be connected to the corresponding light-emitting portions. However, the non-light-emitting portion does not contact the first electrode 400, so the non-light-emitting portion does not emit light. When the two second light-emitting portions 302 are formed simultaneously using the same evaporation opening, the non-light-emitting portion between the two second light-emitting portions 302 is connected together, that is, the two second light-emitting portions 302 are connected together. However, since the non-light-emitting portion does not contact the first electrode 400, the two second light-emitting portions 302 can emit light separately without affecting each other.

[0065] Similarly, two third light-emitting portions 303 adjacently distributed along the first direction X may also be formed simultaneously by using one evaporation opening of a fine metal mask.

[0066] Please refer to Figure 4 The first light-emitting portion 301 may include: a first portion L1 and a second portion L2 connected to each other, the first portion L1 and the second portion L2 may be arranged in the second direction Y, and the orthographic projection of the second portion L2 on the driving backplane 100 may have a first subdivision K. The second light-emitting portion 302 may include: a third portion L3 and a fourth portion L4 connected to each other, the third portion L3 and the fourth portion L4 may be arranged in the second direction Y, and the orthographic projection of the fourth portion L4 on the driving backplane 100 may have a second subdivision M.

[0067] For the first light emitting portion 301 and the second light emitting portion 302 adjacently distributed in the first direction X, the first portion L1 in the first light emitting portion 301 may be adjacently arranged with the third portion L3 in the second light emitting portion 302 in the first direction X, and the second portion L2 in the first light emitting portion 301 may be adjacently arranged with the fourth portion L4 in the second light emitting portion 302 in the first direction X. Among them, the side of the second portion L2 having the first sub-portion K may be opposite to the side of the fourth portion L4 having the second sub-portion M, so that the first sub-portion K may be matched with the second sub-portion M in a concave-convex manner, so that the first light emitting portion 301 and the adjacently distributed second light emitting portion 302 may be arranged more closely, thereby improving the space utilization rate of the display panel 000.

[0068] For the first light-emitting portion 301 and the second light-emitting portion 302 adjacently distributed in the first direction X, the side of the third portion L3 in the second light-emitting portion 302 away from the fourth portion L4 may be flush with the side of the first portion L1 in the first light-emitting portion 301 away from the second portion L2, and the side of the third portion L3 away from the fourth portion L4 may be parallel to the side of the third light-emitting portion 303, and the side of the first portion L1 away from the second portion L2 may also be parallel to the side of the third light-emitting portion 303. The side of the fourth portion L4 in the second light-emitting portion 302 away from the third portion L3 may be flush with the side of the second portion L2 in the first light-emitting portion 301 away from the first portion L1.

[0069] The width of the first part L1 in the first light-emitting portion 301 in the first direction X is X1, the width of the third part L3 in the second light-emitting portion 302 distributed on both sides of the first light-emitting portion 301 in the first direction X is X2, and the length of the third light-emitting portion 303 in the first direction X is X3.

[0070] Since the first light-emitting portion 301 and the two second light-emitting portions 302 distributed on both sides of the first light-emitting portion 301 in the first direction X can have a certain distance respectively, the length X3 of the third light-emitting portion 303 in the first direction X can be greater than the sum of the width X1 of the first part L1 in the first light-emitting portion 301 in the first direction X and the width X2 of the two third parts L3 in the two second light-emitting portions 302 distributed on both sides of the first light-emitting portion 301 in the first direction X.

[0071] Exemplarily, for the two second light-emitting portions 302 distributed on both sides of the first light-emitting portion 301 in the first direction X, the distance between the side of one second light-emitting portion 302 away from the first light-emitting portion 301 and the side of the other second light-emitting portion 302 away from the first light-emitting portion 301 can be equal to the length X3 of the third light-emitting portion 303 in the first direction X.

[0072] like Figure 4As shown, the orthographic projection of the third light-emitting portion 303 on the driving backplane 100 can be a quadrilateral, such as a rectangle, and can also be a parallelogram, a rhombus or other shapes. The orthographic projection of the first light-emitting portion 301 and the two second light-emitting portions 302 distributed on both sides of the first light-emitting portion 301 on the driving backplane 100 can also be approximately rectangular as a whole. Thus, the adjacently distributed first light-emitting portion 301, the second light-emitting portion 302 and the third light-emitting portion 303 can be arranged more closely.

[0073] For the two second light-emitting portions 302 distributed on both sides of the first light-emitting portion 301 in the first direction X, the side of one second light-emitting portion 302 facing away from the first light-emitting portion 301 can be flush with one side of the adjacent third light-emitting portion 303, and the side of the other second light-emitting portion 302 facing away from the first light-emitting portion 301 can be flush with the other side of the adjacent third light-emitting portion 303. That is, the adjacent third light-emitting portion 303, the first light-emitting portion 301 and the two second light-emitting portions 302 located on both sides of the first light-emitting portion 301, the orthographic projection of these four light-emitting portions as a whole on the driving backplane 100 can be approximately a quadrilateral, such as a rectangle. For example, as Figure 5 As shown, the positions of the four light-emitting parts can be properly rotated or rearranged, but the shape of the overall orthographic projection on the driving backplane 100 can be approximately a quadrilateral, such as a rectangle. In this way, a plurality of approximate rectangles can be arranged in an array in the display panel 000, so that a plurality of light-emitting parts can be arranged more closely, thereby effectively utilizing the space of the display panel 000, so that the display panel 000 can be arranged with a greater number of light-emitting parts, thereby increasing the pixel aperture ratio of the display panel 000.

[0074] The orthographic projection of the first light-emitting portion 301 on the driving backplane 100 may have a first subdivision K, and the orthographic projection of the second light-emitting portion 302 on the driving backplane 100 may have a second subdivision M, wherein one of the first subdivision K and the second subdivision M is a concave area, and the other is a convex portion. In one possible implementation, the convex portions in the first subdivision K and the second subdivision M may all be located in the concave area; in another possible implementation, a portion of the convex portion may be located in the concave area, and the other portion may be located outside the concave area. The shape of the concave area may be similar to that of the convex portion, that is, the shape of the first subdivision K may be similar to that of the second subdivision M. The concave area may have a variety of shapes, and the convex portion may also have a variety of shapes, that is, the first subdivision K and the second subdivision M may have a variety of shapes.

[0075] Please refer to Figure 6The first subdivision K may include at least a first boundary 11, a second boundary 12, and a third boundary 13 connected in sequence end to end, and at least one of the first boundary 11, the second boundary 12, and the third boundary 13 may be a straight line boundary. The second subdivision M may include at least a fourth boundary 21, a fifth boundary 22, and a sixth boundary 23 connected in sequence end to end, and at least one of the fourth boundary 21, the fifth boundary 22, and the sixth boundary 23 may be a straight line boundary.

[0076] Among them, the fourth boundary 21 of the second subsection M can be parallel to the first boundary 11 of the first subsection K, the fifth boundary 22 of the second subsection M can be parallel to the second boundary 12 of the first subsection K, and the sixth boundary 23 of the second subsection M can be parallel to the third boundary 13 of the first subsection K. That is, the shape of the second subsection M can be similar to the shape of the first subsection K, so that the concave-convex matching of the first light-emitting portion 301 and the second light-emitting portion 302 can be better achieved, so that the light-emitting portions are arranged more closely.

[0077] Optionally, the first subdivision K may only include the first boundary 11, the second boundary 12, and the third boundary 13 connected end to end, and these three boundaries may all be straight boundaries, that is, the shape of the first subdivision K may be a triangle. In this way, the second subdivision M may also only include the fourth boundary 21, the fifth boundary 22, and the sixth boundary 23 connected end to end, and these three boundaries may also all be straight boundaries, that is, the shape of the second subdivision M may be a triangle, and may be similar to the shape of the first subdivision K.

[0078] Thus, the shapes of the first sub-portion K and the second sub-portion M can both be triangles, and the triangles can also be of various types. That is, there are various implementations of the shapes of the first sub-portion K and the second sub-portion M. The embodiments of the present application are schematically described using the following three implementations as examples.

[0079] For the first implementation, please refer to Figure 6 , Figure 7 and Fig. 9 , the first boundary 11 of the first section K may intersect with the first direction X and may intersect with the second direction Y, the second boundary 12 may be parallel to the first direction X, and the third boundary 13 may be parallel to the second direction Y. The first direction X may intersect with the second direction Y, for example, the first direction X may intersect with the second direction Y perpendicularly, that is, the second boundary 12 may intersect with the third boundary 13 perpendicularly. Thus, the shape of the first section K may be a right triangle.

[0080] Similarly, the fourth boundary 21 of the second division M can intersect with the first direction X and can intersect with the second direction Y, the fifth boundary 22 can be parallel to the first direction X, and the sixth boundary 23 can be parallel to the second direction Y, wherein the fifth boundary 22 can intersect with the sixth boundary 23 perpendicularly, that is, the shape of the second division M can be a right triangle, and is similar to the shape of the first division K.

[0081] However, the first subdivision K is located on the orthographic projection of the first light-emitting portion 301 on the driving backplane 100, and the second subdivision M is located on the orthographic projection of the second light-emitting portion 302 on the driving backplane 100. Therefore, when the arrangement positions of the three boundaries of the first subdivision K are different, the shape of the orthographic projection of the first light-emitting portion 301 on the driving backplane 100 is also different; when the arrangement positions of the three boundaries of the second subdivision M are different, the shape of the orthographic projection of the second light-emitting portion 302 on the driving backplane 100 is also different. The embodiments of the present application are described by taking the following three cases as examples:

[0082] In the first case, please refer to Figure 6 and Figure 7 , the first boundary 11 of the first subsection K may be flush with the side of the second portion L2 of the first light-emitting portion 301 close to the adjacent second light-emitting portion 302, the second boundary 12 may be flush with the side of the second portion L2 away from the first portion L1, and the third boundary 13 may be flush with the side of the first portion L1 close to the adjacent second light-emitting portion 302.

[0083] In this case, the first section K may be a concave area, the second section M may be a convex section, and a portion of the second section M may be located within the first section K, thereby better achieving concave-convex matching between the first light-emitting portion 301 and the second light-emitting portion 302 .

[0084] The orthographic projection of the first light-emitting portion 301 on the driving backplane 100 may have two first sub-portions K arranged opposite to each other in the first direction X, wherein the third boundary 13 of one of the first sub-portions K is flush with the side of the first portion L1 close to the adjacent second light-emitting portion 302, and the third boundary 13 of the other first sub-portion K is flush with the side of the first portion L1 close to the other adjacent second light-emitting portion 302. That is, the maximum distance between the two first sub-portions K of the first light-emitting portion 301 in the first direction X is equal to the width X1 of the first portion L1 of the first light-emitting portion 301 in the first direction X. The minimum distance between the two first sub-portions K in the first direction X may be equal to the minimum width of the second portion L2 of the first light-emitting portion 301 in the first direction X. Figure 6 As shown, the minimum distance between the two first subdivisions K in the first direction X may not be 0, such as Figure 7 As shown, the minimum width of the two first sections K in the first direction X may be 0.

[0085] according to Figure 6 The shapes and positions of the first sub-portion K and the second sub-portion M shown in FIG. 3 and the arrangement of the first light-emitting portion 301 and the adjacent second light-emitting portion 302 can be referred to.

[0086] according to Figure 7 The shapes and positions of the first sub-portion K and the second sub-portion M shown in FIG. 3 and the arrangement of the first light-emitting portion 301 and the adjacent second light-emitting portion 302 can be referred to. Figure 8 The shapes of the first section K and the second section M can both be right triangles, and the shapes of the two are similar.

[0087] In the second case, please refer to Fig. 9 , the first boundary 11 of the first subdivision K may be flush with the side of the second portion L2 of the first light-emitting portion 301 close to the adjacent second light-emitting portion 302, the second boundary 12 may be flush with the side of the first portion L1 close to the second portion L2, and the third boundary 13 may be flush with the side of the first portion L1 close to the second light-emitting portion 302.

[0088] In this case, the first section K may be a concave area, the second section M may be a convex section, and a portion of the second section M may be located within the first section K, thereby better achieving concave-convex matching between the first light-emitting portion 301 and the second light-emitting portion 302 .

[0089] The orthographic projection of the first light-emitting portion 301 on the driving backplane 100 may have two first sub-portions K arranged opposite to each other in the first direction X, wherein the third boundary 13 of one first sub-portion K is flush with the side of the first portion L1 close to the adjacent second light-emitting portion 302, and the third boundary 13 of the other first sub-portion K is flush with the side of the first portion L1 close to the other adjacent second light-emitting portion 302. That is, the maximum distance between the two first sub-portions K of the first light-emitting portion 301 in the first direction X is equal to the width X1 of the first portion L1 of the first light-emitting portion 301 in the first direction X. The minimum distance between the two first sub-portions K in the first direction X may be equal to the minimum width of the second portion L2 of the first light-emitting portion 301 in the first direction X.

[0090] according to Fig. 9 The shapes and positions of the first sub-portion K and the second sub-portion M shown in FIG. 3 and the arrangement of the first light-emitting portion 301 and the adjacent second light-emitting portion 302 can be referred to. Fig.10 The shapes of the first section K and the second section M can both be right triangles, and the shapes of the two are similar.

[0091] For the second implementation, please refer to Fig.11 The first boundary 11 of the first section K may be parallel to the second direction Y, the second boundary 12 may intersect the first direction X and the second direction Y, and the third boundary 13 may also intersect the first direction X and the second direction Y. Thus, the shape of the first section K may be a triangle.

[0092] Similarly, the fourth boundary 21 of the second subsection M may be parallel to the second direction Y, the fifth boundary 22 may intersect the first direction X and the second direction Y, and the sixth boundary 23 may intersect the first direction X and the second direction Y. That is, the shape of the second subsection M may be a triangle, which is similar to the shape of the first subsection K.

The fourth boundary 21 of the second subdivision M may be flush with the side of the third portion L3 of the second light-emitting portion 302 close to the adjacent first light-emitting portion 301, the fifth boundary 22 may be flush with the side of the fourth portion L4 close to the adjacent first light-emitting portion 301, and the sixth boundary 23 may be flush with the other side of the fourth portion L4 close to the adjacent first light-emitting portion 301.

[0094] In this case, the first section K may be a convex portion, the second section M may be a concave area, and a portion of the first section K may be located within the second section M, thereby better achieving the concave-convex fit between the first light-emitting portion 301 and the second light-emitting portion 302 .

[0095] The orthographic projection of the first light-emitting portion 301 on the driving backplane 100 may have two first sub-portions K arranged opposite to each other in the first direction X, wherein the first boundary 11 of one first sub-portion K is flush with the side of the first portion L1 close to the adjacent second light-emitting portion 302, and the first boundary 11 of the other first sub-portion K is flush with the side of the first portion L1 close to the other adjacent second light-emitting portion 302. That is, the minimum distance between the two first sub-portions K of the first light-emitting portion 301 in the first direction X is equal to the width X1 of the first portion L1 of the first light-emitting portion 301 in the first direction X. The maximum distance between the two first sub-portions K in the first direction X may be equal to the maximum width of the second portion L2 of the first light-emitting portion 301 in the first direction X.

[0096] according to Fig.11 The shapes and positions of the first sub-portion K and the second sub-portion M shown in FIG. 3 and the arrangement of the first light-emitting portion 301 and the adjacent second light-emitting portion 302 can be referred to. Fig.12 The shapes of the first section K and the second section M can both be triangles, and the shapes of the two are similar.

[0097] For the third implementation method, please refer to Fig.13 The first boundary 11 of the first section K may intersect with the first direction X and the second direction Y, the second boundary 12 may intersect with the first direction X and the second direction Y, and the third boundary 13 may intersect with the first direction X and the second direction Y.

[0098] Similarly, the fourth boundary 21 of the second subsection M may intersect with the first direction X and the second direction Y, the fifth boundary 22 may intersect with the first direction X and the second direction Y, and the sixth boundary 23 may intersect with the first direction X and the second direction Y. That is, the shape of the second subsection M may be a triangle, which is similar to the shape of the first subsection K.

[0099] Please refer to Fig.13The second boundary 12 of the first subsection K may be flush with one side of the second portion L2 of the first light-emitting portion 301 close to the adjacent second light-emitting portion 302, and the third boundary 13 may be flush with the other side of the second portion L2 close to the adjacent second light-emitting portion 302. The fifth boundary 22 of the second subsection M may be flush with one side of the fourth portion L4 of the second light-emitting portion 302 close to the adjacent first light-emitting portion 301, and the sixth boundary 23 may be flush with the other side of the fourth portion L4 close to the adjacent first light-emitting portion 301.

[0100] In this case, the first section K may be a convex portion, the second section M may be a concave area, and a portion of the first section K may be located within the second section M, thereby better achieving the concave-convex fit between the first light-emitting portion 301 and the second light-emitting portion 302 .

The maximum distance between the two first subdivisions K in the first direction X may be equal to the maximum width of the second portion L2 of the first light-emitting portion 301 in the first direction X.

[0102] according to Fig.13 The shapes and positions of the first sub-portion K and the second sub-portion M shown in FIG. 3 and the arrangement of the first light-emitting portion 301 and the adjacent second light-emitting portion 302 can be referred to.

[0103] In summary, the embodiment of the present application provides a display panel, and the two second light-emitting parts can be respectively located on both sides of the same first light-emitting part in the first direction, and the orthographic projection of the first light-emitting part on the driving backplane has two first divisions arranged opposite to each other in the first direction, and the orthographic projection of the second light-emitting part on the driving backplane has a second division corresponding to the first division. One of the first division and the second division can be a concave area, and the other can be a convex part. The convex part can be located at least in the concave area, that is, the first division and the second division can achieve concave-convex matching. In this way, a close arrangement can be achieved between the first light-emitting part and the two adjacently distributed second light-emitting parts. In this way, the space of the display panel can be reasonably utilized, and the screen space utilization rate of the display panel can be improved, so that the display panel can be arranged with more light-emitting parts, thereby increasing the light-emitting area and improving the aperture ratio of the display panel.

[0104] The embodiment of the present application also provides a method for manufacturing a display panel, which can be used to manufacture a display panel 000. The method for manufacturing a display panel may include: forming a pixel definition layer on one side of a driving backplane, the pixel definition layer having a plurality of pixel openings; forming a light-emitting layer on a side of the pixel definition layer away from the driving backplane, the light-emitting layer including a plurality of light-emitting parts, the plurality of light-emitting parts corresponding to the plurality of pixel openings one by one, and the light-emitting parts being located in the corresponding pixel openings. The following embodiment will describe in detail each step in the method for manufacturing a display panel:

[0105] Step S101: providing a driving backplane having a plurality of thin film transistors and a plurality of first electrodes.

[0106] In the examples of this application, please refer to Figure 3 The plurality of first electrodes 400 may be located on one side of the driving backplane 100, and the first electrodes 400 may be anodes. The driving backplane 100 may include a plurality of thin film transistors 104, and the plurality of thin film transistors 104 may be electrically connected to the plurality of first electrodes 400 in a one-to-one correspondence, thereby driving the display panel 000 to display images.

[0107] Step S102: forming a pixel definition layer on one side of the driving backplane.

[0108] A pixel definition film is formed on a driving backplane 100 having a plurality of thin film transistors 104, and a single patterning process is performed on the pixel definition film to form a pixel definition layer 200. The pixel definition layer 200 has a plurality of pixel openings U, and the plurality of pixel openings U correspond one-to-one to the plurality of first electrodes 400, and the orthographic projections of the pixel openings U on the driving backplane 100 are located within the orthographic projections of the corresponding first electrodes 400 on the driving backplane 100. The single patterning process may include: photoresist coating, exposure, development, etching, and photoresist stripping.

[0109] Step S103 , forming a light-emitting layer on a side of the pixel definition layer away from the driving backplane.

[0110] The light-emitting layer 300 may include a plurality of light-emitting portions, and the plurality of light-emitting portions correspond to the plurality of pixel openings U one by one, and the light-emitting portions may be located in the corresponding pixel openings U. The plurality of light-emitting portions in the light-emitting layer 300 may be formed by evaporation using a fine metal mask. The fine metal mask includes a plurality of evaporation openings, and after the evaporation material is attached to the driving backplane 100 through the evaporation openings, a plurality of light-emitting portions may be formed on the driving backplane 100.

[0111] like Figure 1As shown, the plurality of light emitting units may include a plurality of first light emitting units 301, a plurality of second light emitting units 302, and a plurality of third light emitting units 303. The two second light emitting units 302 may be located on both sides of the same first light emitting unit 301 in the first direction X, the third light emitting unit 303 may be located on one side of the first light emitting unit 301 in the second direction Y, and the third light emitting unit 303 may also be located on one side of the two second light emitting units 302 at the same time in the second direction Y. The first direction X may intersect with the second direction Y.

[0112] The orthographic projection of the first light-emitting portion 301 on the driving backplane 100 may have two first sub-portions K, and the orthographic projection of the second light-emitting portion 302 on the driving backplane 100 may have a second sub-portion M corresponding to the first sub-portion K. One of the first sub-portion K and the second sub-portion M may be a concave area, and the other may be a convex portion. The convex portion may be completely located in the concave area, or a part of the convex portion may be located in the concave area.

[0113] Furthermore, the light emitting color of the first light emitting portion 301 may be blue, the light emitting color of the second light emitting portion 302 may be one of red and green, and the light emitting color of the third light emitting portion 303 may be the other of red and green.

[0114] The formation process of the light-emitting layer 300 is as follows: on the side of the pixel definition layer 200 away from the driving backplane 100, a fine metal mask is first used to form a plurality of first light-emitting portions 301, then another fine metal mask is used to form a plurality of second light-emitting portions 302, and finally another fine metal mask is used to form a plurality of third light-emitting portions 303. The evaporation order of the first light-emitting portion 301, the second light-emitting portion 302 and the third light-emitting portion 303 can be interchanged.

[0115] Step S104: forming a second electrode on a side of the light-emitting layer away from the driving backplane.

[0116] The second electrode 500 is formed on the driving backplane 100 formed with the light emitting layer 300 by a sputtering process. The second electrode 500 may be a cathode.

[0117] In summary, the embodiment of the present application provides a method for manufacturing a display panel, and the manufactured display panel includes: a plurality of first light-emitting parts, a plurality of second light-emitting parts, and a plurality of third light-emitting parts. The two second light-emitting parts can be respectively located on both sides of the same first light-emitting part in the first direction, and the orthographic projection of the first light-emitting part on the driving backplane has two first divisions arranged oppositely in the first direction, and the orthographic projection of the second light-emitting part on the driving backplane has a second division corresponding to the first division. One of the first division and the second division can be a concave area, and the other can be a convex part, and the convex part can be at least located in the concave area, that is, the first division and the second division can achieve concave-convex matching. In this way, the first light-emitting part can be closely arranged with the two adjacently distributed second light-emitting parts. In this way, the space of the display panel can be reasonably utilized, the screen space utilization rate of the display panel can be improved, and more light-emitting parts can be arranged on the display panel, so that the light-emitting area can be increased and the aperture ratio of the display panel can be improved.

[0118] The embodiment of the present application also provides a display device, which can be any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a laptop computer, a digital photo frame, a navigator, etc. The display device may include a drive component and a display panel, and the display panel may be the display panel 000 in the above embodiment. The drive component may be electrically connected to the display panel 000, so as to drive the display panel 000 to display a picture.
