[0034] refer to Figure 1 As shown, the display panel 10 includes a plurality of light-emitting elements 200. By driving the light-emitting elements 200 to emit light, the display effect of the display panel 10 is achieved. The light-emitting elements 200 may include light-emitting elements of different light-emitting colors, such as red light-emitting elements, green light-emitting elements, and blue light-emitting elements. By driving the light-emitting elements 200 of different colors to emit light, the color display effect of the display panel 10 can be achieved. Specifically, the light-emitting elements 200 may include a first color light-emitting element 210 and a second color light-emitting element 220. Optionally, refer to Figures 1 to 3 As shown, the display panel 10 may further include a third color light emitting element 230. For example, the first color light emitting element 210 may be a red light emitting element, the second color light emitting element 220 may be a green light emitting element, and the third color light emitting element 230 may be a blue light emitting element. The specific light emitting colors of the first color light emitting element 210, the second color light emitting element 220, and the third color light emitting element 230 may be adaptively adjusted according to different display panel 10 requirements. It should be noted that Figures 1 to 3As shown, light emitting elements 200 of different colors are shown with different filling patterns.
[0035] refer to Figure 2 , Figure 4 and Figure 5 As shown, the display panel 10 also includes a pixel defining structure 300. The pixel defining structure 300 and the light-emitting element 200 are both located on one side of the base substrate 100. The pixel defining structure 300 can be located between two adjacent light-emitting elements 200. The light-emitting elements 200 of different colors can be separated by the pixel defining structure 300.
[0036] For further reference, Figures 2 to 5 As shown, the display panel 10 further includes a partition structure 400, and the partition structure 400 penetrates at least a portion of the pixel definition structure 300. Figure 4 and Figure 5 The partition structure 400 is shown to penetrate part of the pixel defining structure 300. Optionally, the partition structure 400 may penetrate part of the pixel defining structure 300, or may penetrate the entire pixel defining structure 300, or may extend into the film layer in the base substrate 100. The embodiment of the present invention does not specifically limit the depth setting of the partition structure 400 along the direction of the display panel 10, and may be adaptively adjusted according to actual needs. The partition structure 400 can be understood as an area where a groove is formed at the pixel defining structure 300, and the partition structure 400 can be located between two adjacent light-emitting elements 200. The setting of the partition structure 400 can effectively alleviate the leakage between light-emitting elements 200 of different colors, thereby ensuring the overall display effect of the display panel 10. Specifically, refer to Figure 4 and Figure 5 As shown, the light-emitting element 200 includes a film layer that is evaporated on the entire surface. The film layer that is evaporated on the entire surface has an extension path added at the partition structure 400, which can effectively alleviate the leakage current transmission between different light-emitting elements 200 and ensure the light-emitting stability of the light-emitting element 200, thereby improving the overall display effect of the display panel 10.
[0037] Specifically, refer to Figure 2 and Figure 3 As shown, the partition structure 400 includes a first partition unit 410 and a second partition unit 420. The extension direction of the first partition unit 410 is the same as the arrangement direction of the first color light emitting element 210 and the second color light emitting element 220, that is, the first partition unit 410 extends along the first direction X1, and the second partition unit 420 extends along the second direction X2. Figure 2 As shown, along the second direction X2, one side of the second partition unit 420 is connected to the first partition unit 410; Figure 3As shown, along the second direction X2, both sides of the second partition unit 420 are connected to the first partition unit 410, and there are various ways to connect the second partition unit 420 and the first partition unit 410. The first partition unit 410 and the second partition unit 420 are connected and surrounded to form a semi-enclosed structure, which surrounds part of the light-emitting elements 200. On the one hand, the semi-enclosed partition structure 400 can reduce the leakage current between light-emitting elements 200 of different colors, and on the other hand, it will not affect the transmission of normal electrical signals between the light-emitting elements 200, that is, it will not affect the normal display of the light-emitting elements 200. The partition structure 400 surrounds at least part of the light-emitting elements 200, which can ensure that the partition structure alleviates the leakage current transmission between different light-emitting elements 200, thereby improving the overall display effect of the display panel 10.
[0038] For further reference, Figure 2 and Figure 3 As shown, the orthographic projection of the second partition unit 420 onto the base substrate 100 is located between the orthographic projection of the first color light emitting element 210 onto the base substrate 100 and the orthographic projection of the second color light emitting element 220 onto the base substrate 100. In other words, Figure 2 and Figure 3 As shown in the top view, the second partition unit 420 is located between the first color light emitting element 210 and the second color light emitting element 220 . The second partition unit 420 can effectively alleviate the leakage between the first color light emitting element 210 and the second color light emitting element 220 .
[0039] For further reference, Figure 2 and Figure 3 As shown, the orthographic projection of the second partition unit 420 along the first direction X1 covers the orthographic projection of the first color light emitting element 210 along the first direction X1, and the orthographic projection of the second partition unit 420 along the first direction X1 covers the orthographic projection of the second color light emitting element 220 along the first direction X1. In other words, the second partition unit 420 located between the first color light emitting element 210 and the second color light emitting element 220 is a continuous structure without a break. Under the condition that the light emitting elements 200 of different colors can be displayed normally, by adjusting the setting positions of the first partition unit 410 and the second partition unit 420, the continuity and integrity of the second partition unit 420 can be ensured, which can more effectively avoid the leakage between the first color light emitting element 210 and the second color light emitting element 220. At the same time, the second partition unit 420 is a continuous integral structure. When preparing the partition structure 400, there is no need to further etch the second partition unit 420, which can reduce the difficulty of the process preparation of the display panel 10 and reduce the process preparation cost of the display panel 10.
[0040] In summary, the display panel provided by the embodiment of the present invention, the partition structure in the display panel includes a first partition unit and a second partition unit, the first partition unit and the second partition unit can partially surround the light-emitting element, that is, the first partition unit and the second partition unit form a semi-enclosed structure to surround the light-emitting element; further, the second partition unit is located between the first color light-emitting element and the second color light-emitting element; and the second partition unit between the first color light-emitting element and the second color light-emitting element is a continuous structure, which can better reduce the leakage between light-emitting elements of different colors and further improve the overall display effect of the display panel.
[0041] Figure 6 yes Figure 2 The second cross-sectional diagram along the section line C-C', refer to Figures 1 to 3 , Figure 6 As shown, the base substrate 100 includes a driving circuit 110, and the driving circuit 110 includes at least one transistor 111; the light-emitting element 200 includes a first electrode layer 200A, a common electrode layer 200B and a second electrode layer 200C; the first electrode layer 200A is located on one side of the base substrate 100, and is electrically connected to the driving circuit 110 through a connecting via 200D; the common electrode layer 200B is located on a side of the first electrode layer 200A away from the base substrate 100, and the second electrode layer 200C is located on a side of the common electrode 200B layer away from the first electrode layer 200A; the pixel defining structure 300 includes a first groove 310, and the first groove 310 passes through the pixel defining structure 300 and exposes at least a portion of the first electrode layer 200A; the orthographic projection of the connecting via 200D onto the base substrate 100 intersects with the orthographic projection of the first electrode layer 200A onto the base substrate 100.
[0042] The substrate 100 includes a driving circuit 110, which includes a plurality of transistors 111. The transistors 111 are electrically connected to the light-emitting element 200 to provide a driving current for the light-emitting element 200, thereby ensuring the normal display of the display panel 10. Further, the driving circuit 110 may include "4T1C", "7T1C" and "8T1C", etc., where "T" represents a transistor, "C" represents a capacitor, Figure 6 The driving circuit 110 is not specifically shown in the figure, and only a transistor 111 is used as an example. Further, the substrate 100 includes a plurality of stacked film layers, such as a substrate layer 101, a gate insulating layer 102, an interlayer insulating layer 103, and a flat insulating layer 104. The specific film layer type and quantity in the substrate 100 can be adaptively adjusted according to different requirements, and the embodiment of the present invention does not make specific limitations here. Further, Figure 6The transistor 111 shown in the driving circuit 110 includes: an active layer 111a, a gate 111b, a source 111c and a drain 111d. The specific configuration of the transistor 111 can also be adaptively adjusted according to requirements, and the embodiment of the present invention does not specifically limit this.
[0043] For further reference, Figure 2 , Figures 4 to 6 As shown, the light-emitting element 200 includes a first electrode layer 200A, a common electrode layer 200B and a second electrode layer 200C. Along the thickness direction of the display panel 10, the common electrode layer 200B is located between the first electrode layer 200A and the second electrode layer 200C. The first electrode layer 200A is electrically connected to the driving circuit 110 through the connecting via 200D, thereby realizing the electrical connection between the driving circuit 110 and the light-emitting element 200. The light-emitting principle of the light-emitting element 200 can be understood as follows: a certain voltage is applied to the first electrode layer 200A and the second electrode layer 200C respectively, and the holes from the first electrode layer 200A and the electrons from the second electrode layer 200C converge in the light-emitting film layer in the common electrode layer 200B, and are further excited to emit light, thereby realizing the light-emitting of the light-emitting element 200. Combined with Figures 2 to 6 As shown, a partition structure 400 is arranged between adjacent light-emitting elements 200. The partition structure 400 can increase the extension path of the common electrode layer 200B, and can reduce the leakage transmission of holes or electrons between different light-emitting elements 200, thereby improving the overall display effect of the display panel; if the size of the partition structure 400 is large, the common electrode layer 200B may also be disconnected, thereby directly avoiding or reducing the leakage transmission of holes or electrons between different light-emitting elements 200.
[0044] For further reference, Figures 2 to 6 As shown, the pixel defining structure 300 includes a first groove 310, which runs through the pixel defining structure 300 and exposes part of the first electrode 200A. In other words, the first groove 310 can be understood as a pixel opening, and the exposed first electrode 200A can be understood as the setting area of the light-emitting element 200, that is, the pixel opening limits the size of the light-emitting element 200.
[0045] The orthographic projection of the connecting via 200D onto the base substrate 100 overlaps with the orthographic projection of the first electrode layer 200A onto the base substrate 100. Figure 2 and Figure 6 As shown, the orthographic projection of the connecting via 200D onto the base substrate 100 may overlap with the orthographic projection of the first groove 310 onto the base substrate 100; or refer to Figure 3As shown, the orthographic projection of the connecting via 200D onto the base substrate 100 may not overlap with the orthographic projection of the first groove 310 onto the base substrate 100. The specific setting position of the connecting via 200D is flexible, wherein the partition structure 400 can be flexibly adjusted according to the specific setting mode of the connecting via 200D to ensure the overall continuity of the partition structure 400.
[0046] Figure 7 yes Figure 1 The third enlarged schematic diagram of the A area in the middle, Figure 8 yes Figure 7 The second cross-sectional diagram along the section line D-D', refer to Figure 2 , Figures 6 to 8 As shown, the driving circuit 110 includes a first driving circuit 110A; the connecting via 200D includes a first via 200D1, the first color light-emitting element 210 includes a first electrode layer portion 200A1, and the first electrode layer portion 200A1 is electrically connected to the first driving circuit 110A through the first via 200D1; the first groove 310 includes a first groove portion 311, and the first groove portion 311 exposes at least a portion of the first electrode layer portion 200A1; the first electrode layer portion 200A1 includes a first side N1, and the orthographic projection of the side N2 of the first via 200D1 onto the substrate substrate 100 is tangent to the orthographic projection of the first side N1 onto the substrate substrate 100; the orthographic projection of the center of the first via 200D1 onto the substrate substrate 100 is located on the side of the orthographic projection of the first side N1 onto the substrate substrate 100, close to the orthographic projection of the center of the first electrode layer portion 200A1 onto the substrate substrate 100.
[0047] Among them, reference Figure 2 , Figures 6 to 8 As shown, the first color light emitting element 210 includes a first electrode layer sub-portion 200A1, and the first electrode layer sub-portion 200A1 is electrically connected to the first driving circuit 110A through the first via hole 200D1. The first driving circuit 110A realizes display driving of the first color light emitting element 210 through the first via hole 200D1. Further, the first groove 310 includes a first groove sub-portion 311, and the first groove sub-portion 311 is used to expose part of the first electrode layer sub-portion 200A1, that is, the first groove sub-portion 311 is a pixel opening corresponding to the first color light emitting element 210.
[0048] Specifically, refer to Figure 2 , Figures 6 to 8As shown, the first electrode layer subdivision 200A1 includes a first side N1, and the orthographic projection of the side N2 of the first via hole 200D1 onto the substrate 100 is tangent to the orthographic projection of the first side N1 onto the substrate 100. In other words, the projection of the first via hole 200D1 onto the substrate 100 intersects with the projection of the first electrode layer subdivision 200A1 onto the substrate 100, and the two sides are tangent. Further, the orthographic projection of the center of the first via hole 200D1 onto the substrate 100 is located on the side of the orthographic projection of the first side N1 onto the substrate 100 close to the orthographic projection of the center of the first electrode layer subdivision 200A1 onto the substrate 100; that is, the center of the first via hole 200D1 is close to the center of the first electrode layer subdivision 200A1. In general, the orthographic projection of the first via hole 200D1 onto the base substrate 100 overlaps with the orthographic projection of the first electrode layer portion 200A1 onto the base substrate 100 , and the side N2 of the first via hole 200D1 is tangent to the first side N1 of the first electrode layer portion 200A1 .
[0049] Further, the setting position of the first via hole 200D1 is adjusted, and the projection of the first via hole 200D1 along the first direction X1 is set not to overlap with the projection of the first partition unit 410 along the first direction X1. In other words, the setting of the first partition unit 410 does not need to consider avoiding the first via hole 200D1, so the continuity and integrity of the setting of the first partition unit 410 can be guaranteed. The continuity and integrity of the first partition unit 410 along the first direction X1 can reduce the difficulty of the process preparation of the display panel 10. On the other hand, the first partition unit 410 can better block the transmission of holes or electrons between different light-emitting elements 200 along the second direction X2, and ensure the overall display effect of the display panel 10. Similarly, the projection of the first via hole 200D1 along the second direction X2 and the projection of the second partition unit 420 along the second direction X2 do not overlap, and the continuity and integrity of the second partition unit can also be better guaranteed.
[0050] Continue to refer Figure 2 , Figures 4 to 8As shown, the first partition unit 410 includes a first partition sub-section 411 and a second partition sub-section 412. Along the second direction X2, the first partition sub-section 411 and the second partition sub-section 412 are located on both sides of the light-emitting element 200; the second partition unit 420 includes a third partition sub-section 421 and a fourth partition sub-section 422. Along the first direction X1, the third partition sub-section 421 is located on the side of the adjacent first color light-emitting element 210 away from the second color light-emitting element 220, and the fourth partition sub-section 422 is located on the side of the adjacent first color light-emitting element 210 away from the second color light-emitting element 220. The light-emitting element 210 is close to the side of the second color light-emitting element 220; the third partition section 421 is connected to the second partition section 412, and the fourth partition section 422 is respectively connected to the first partition section 411 and the second partition section 412; the first partition section 411 includes a first break 411a, and the orthographic projection of the first break 411a along the second direction X2 is located on the side of the orthographic projection of the adjacent third partition section 421 along the second direction X2 close to the orthographic projection of the first electrode layer section 200A1 along the second direction X2.
[0051] Specifically, refer to Figure 2 , Figures 4 to 8 As shown, the first partition unit 410 includes a first partition sub-section 411 and a second partition sub-section 412, wherein the first partition sub-section 411 and the second partition sub-section 412 both extend along the first direction X1, and the first partition sub-section 411 and the second partition sub-section 412 are located on both sides of the light emitting element 200 along the second direction X2, so as to block the leakage of the light emitting elements 200 of different colors along the second direction X2, thereby ensuring the overall display effect of the display panel 10. Further, referring to Figure 2 , Figures 4 to 8 As shown, the second partition unit 420 includes a third partition sub-section 421 and a fourth partition sub-section 422, wherein the third partition sub-section 421 and the fourth partition sub-section 422 both extend along the second direction X2, and the third partition sub-section 421 and the fourth partition sub-section 422 are located on both sides of the first color light emitting element 210 or the second color light emitting element 420 along the second direction X2, and are used to block the leakage of different first color light emitting elements 210 and second color light emitting elements 220 along the first direction X1, so as to ensure the overall display effect of the display panel 10. Specifically, refer to Figure 2 and Figure 7 As shown, along the first direction X1, the third partition sub-section 421 is located on the side of the adjacent first color light emitting element 210 away from the second color light emitting element 220, and the fourth partition sub-section 422 is located on the side of the adjacent first color light emitting element 210 close to the second color light emitting element 220. In other words, the third partition sub-section 421 and the fourth partition sub-section 422 are alternately arranged in sequence along the first direction X1.
[0052] Among them, reference Figure 2As shown, the third partition sub-section 421 is connected to the second partition sub-section 412, and the third partition sub-section 421 is also connected to the first partition sub-section 411. That is, along the second direction X2, both sides of the third partition sub-section 421 can be connected to the first partition unit 410. Or refer to Figure 7 As shown, the third partition sub-section 421 is connected to the second partition sub-section 412, that is, along the second direction X2, one side of the third partition sub-section 421 can be connected to the first partition unit 410. The connection of the third partition sub-section 421 along the second direction X2 can be adaptively adjusted according to different display panels 10, reflecting the flexibility of the partition structure 400. Figure 2 and Figure 7 As shown, the fourth partition section 422 is connected to the first partition section 411 and the second partition section 412 respectively, so that the first partition unit 410 and the second partition unit 420 can form a semi-enclosed structure, which is used to reduce or avoid leakage between light-emitting elements 200 of different colors, thereby ensuring the overall display effect of the display panel 10.

It can be understood that the setting of the first break 411a can ensure that the partition structure 400 surrounding the first color light emitting element 210 is a semi-enclosed structure, and thus will not affect the transmission of normal electrical signals of the first color light emitting element 210, that is, will not affect the normal display of the first color light emitting element 210.
[0054] Continue to refer Figure 2 and Figure 7 As shown, the minimum distance between the orthographic projection of the center of the first via 200D1 onto the base substrate 100 and the orthographic projection of the adjacent third partition section 421 onto the base substrate 100 is L1, and the minimum distance between the orthographic projection of the center of the first via 200D1 onto the base substrate 100 and the orthographic projection of the adjacent fourth partition section 422 onto the base substrate 100 is L2; wherein, |L1-L2| / L2≤20%.
[0055] For further reference, Figure 2 and Figure 7 As shown, specific reference Figure 2As shown, the minimum distance between the orthographic projection of the center of the first via 200D1 to the substrate 100 and the orthographic projection of the adjacent third partition sub-section 421 to the substrate 100 is L1, and the distance between the orthographic projection of the center of the first via 200D1 to the substrate 100 and the orthographic projection of the adjacent fourth partition sub-section 422 to the substrate 100 is L2. For L1 and L2, |L1-L2| / L2≤20%, and the values of L1 and L2 can be the same or similar. That is, along the first direction X1, the first via 200D1 is located in the middle area of the third partition sub-section 421 and the fourth partition sub-section 422; that is, along the orthographic projection of the second direction X2, the connecting via 200D connected to the first color light emitting element 210 is set in the relatively central area of the partition structure 400. By setting the connecting via 200D in an area close to the center, the signal received by the first color light emitting element 210 through the connecting via 200D can be ensured to be balanced as much as possible, thereby ensuring the overall display effect of the display panel 10, and the relatively central setting position is conducive to reducing the difficulty of the process preparation of the display panel 10.

[0057] Among them, reference Figure 2 , Figure 3 , Figure 7 and Fig. 9As shown, the second color light emitting element 220 includes a second electrode layer sub-portion 200A2, and the second electrode layer sub-portion 200A2 is electrically connected to the second driving circuit 110B through the second via hole 200D2. The second driving circuit 110B realizes display driving of the second color light emitting element 220 through the second via hole 200D2. Further, the first groove 310 includes a second groove sub-portion 312, and the second groove sub-portion 312 is used to expose part of the second electrode layer sub-portion 200A2, that is, the second electrode layer sub-portion 200A2 is a pixel opening corresponding to the second color light emitting element 220.
[0058] For further reference, Figure 2 and Figure 7 As shown, the first partition section 411 further includes a second break 411b, and the orthographic projection of the second break 411b along the second direction X2 is located on the side where the orthographic projection of the adjacent third partition section 421 along the second direction X2 is close to the orthographic projection of the adjacent second electrode layer section 200A2 along the second direction X2. It can be understood that the setting of the second break 411b can reflect that the partition structure 400 surrounding the second color light-emitting element 220 is a semi-enclosed structure, and thus will not affect the transmission of normal electrical signals of the second color light-emitting element 220, that is, will not affect the normal display of the first color light-emitting element 210. Furthermore, the second partition section 412 further includes a third break 412a, and the orthographic projection of the second break 411b along the second direction X2 at least partially overlaps with the orthographic projection of the third break 412a along the second direction X2. It can be understood that the second break 411b and the third break 412a can better ensure the transmission of the lateral current corresponding to the second color light-emitting element 220, and ensure the lateral uniform display of the display panel 10. Among them, the second break 411b and the third break 412a can have overlapping projections along the second direction X2, which can ensure the overall continuity of the second electrode layer 200C, and then ensure the display effect of the light-emitting element 200 in the display panel 10; on the other hand, it can also ensure that the overall structure of the display panel 10 has regularity, reducing the difficulty of the process preparation of the display panel 10.
[0059] Furthermore, the orthographic projection of the second via hole 200D2 along the second direction X2 overlaps at least partially with the orthographic projection of the third break 412a along the second direction X2. Since the location of the second via hole 200D2 overlaps with the projection of the third break 412a along the second direction X2, the second partition section 412 does not need to consider avoiding the second via hole 200D2, and the arrangement of the second via hole 200D2 is flexible. Figure 2 or Figure 7As shown, the orthographic projection of the side of the second via hole 200D2 onto the base substrate 100 may be tangent to the orthographic projection of the side of the second electrode layer subdivision 200A2 onto the base substrate 100, and the center of the second via hole 200D2 is closer to the center of the second electrode layer subdivision 200A2 than the side of the second electrode layer subdivision 200A2. Optionally, Fig.10 yes Figure 1 The fourth enlarged schematic diagram of the A area in the middle, refer to Fig.10 As shown, the orthographic projection of the side of the second via 200D2 onto the substrate 100 may be tangent to the orthographic projection of the side of the second groove portion 312 onto the substrate 100 , and the center of the second via 200D2 is farther away from the center of the second electrode layer portion 200A2 than the side of the second groove portion 312 .
[0060] Continue to refer Figure 2 As shown, the orthographic projection of the first break 411a along the second direction X2 and the orthographic projection of the second break 411b along the second direction X2 are located on both sides of the orthographic projection of the adjacent third partition section 421 along the second direction X2; the first break 411a and the second break 411b are not connected; the minimum spacing between the orthographic projection of the center of the second via 200D2 onto the substrate 100 and the orthographic projection of the adjacent third partition section 421 onto the substrate 100 is L3, and the minimum spacing between the orthographic projection of the center of the second via 200D2 onto the substrate 100 and the orthographic projection of the adjacent fourth partition section 422 onto the substrate 100 is L4; wherein, |L3-L4| / L4≤20%.
[0061] For further reference, Figure 2 As shown, the first partition section 411 includes a first break 411a and a second break 411b, and the orthographic projection of the first break 411a along the second direction X2 and the orthographic projection of the second break 411b along the second direction X2 are located on both sides of the orthographic projection of the adjacent third partition section 421 along the second direction X2. Along the first direction X1, part of the first partition section 411 exists between the first break 411a and the second break 411b, that is, the first break 411a and the second break 411b are not connected.
[0062] For further reference, Figure 2As shown, the minimum distance between the orthographic projection of the center of the second via 200D2 to the substrate 100 and the orthographic projection of the adjacent third partition sub-section 421 to the substrate 100 is L3, and the minimum distance between the orthographic projection of the center of the second via 200D2 to the substrate 100 and the orthographic projection of the adjacent fourth partition sub-section 422 to the substrate 100 is L4. For L3 and L4, |L3-L4| / L4≤20%, and the values of L3 and L4 can be the same or similar. That is, along the first direction X1, the second via 200D2 is located in the middle area of the third partition sub-section 421 and the fourth partition sub-section 422; that is, along the orthographic projection of the second direction X2, the connecting via 200D connected to the second color light emitting element 220 is set in the relatively central area of the partition structure 400. By setting the connecting via 200D in an area close to the center, the signal received by the second color light emitting element 220 through the connecting via 200D can be ensured to be balanced as much as possible, thereby ensuring the overall display effect of the display panel 10, and the relatively central setting position is conducive to reducing the difficulty of the process preparation of the display panel 10.
[0063] Continue to refer Figure 7 As shown, the first break 411a and the second break 411b are connected; the minimum distance between the orthographic projection of the center of the second via 200D2 onto the substrate 100 and the orthographic projection of the adjacent third partition section 421 onto the substrate 100 is L5, and the minimum distance between the orthographic projection of the side of the second electrode layer section 200A2 close to the adjacent third partition section 421 onto the substrate 100 and the orthographic projection of the adjacent third partition section 421 onto the substrate 100 is L6, wherein |L5-L6| / L6≤20%.
[0064] For further reference, Figure 7 As shown, the first partition section 411 includes a first break 411a and a second break 411b, and the first break 411a and the second break 411b are connected. Figure 7 As shown in the middle area F, the first break 411a and the second break 411b form a larger break. By connecting the first break 411a and the second break 411b, during the process of manufacturing the display panel 10, the first break 411a and the second break 411b can be manufactured simultaneously, thereby reducing the difficulty of manufacturing the display panel 10 and reducing the process cost of the display panel 10.
[0065] For further reference, Figure 7As shown, the minimum distance between the orthographic projection of the center of the second via hole 200D2 to the substrate 100 and the orthographic projection of the adjacent third partition sub-section 421 to the substrate 100 is L5, and the minimum distance between the orthographic projection of the side of the second electrode layer sub-section 200A2 close to the adjacent third partition sub-section 421 to the substrate 100 and the orthographic projection of the adjacent third partition sub-section 421 to the substrate 100 is L6, and L5 and L6 satisfy: |L5-L6| / L6≤20%, and the values of L5 and L6 can be the same or similar. In other words, the orthographic projection of the second via hole 200D2 to the substrate 100 is close to the side of the adjacent third partition sub-section 421, that is, the setting position of the second via hole 200D2 is flexibly adjusted according to the setting position of the fracture at the partition structure 400.
[0066] Fig.11 yes Figure 3 A schematic cross-sectional view along the section line G-G', see Figure 3 and Fig.11 As shown, the driving circuit 110 includes a third driving circuit 110C; the connecting via 200D includes a third via 200D3, the first color light-emitting element 210 includes a third electrode layer portion 200A3, and the third electrode layer portion 200A3 is electrically connected to the third driving circuit 110C through the third via 200D3; the first groove 310 includes a third groove portion 313, and the third groove portion 313 exposes at least a portion of the third electrode layer portion 200A3; the third groove portion 313 includes a second side N3, and the orthographic projection of the side N4 of the third via 200D3 onto the substrate substrate 100 is tangent to the orthographic projection of the second side N3 onto the substrate substrate 100; the orthographic projection of the center of the third via 200D3 onto the substrate substrate 100 is located on the side of the orthographic projection of the second side N3 onto the substrate substrate 100 away from the orthographic projection of the center of the third groove portion 313 onto the substrate substrate 100.
[0067] Among them, reference Figure 3 and Fig.11 As shown, the first color light emitting element 210 includes a third electrode layer division 200A3, and the third electrode layer division 200A3 is electrically connected to the third driving circuit 110C through the third via hole 200D3. The third driving circuit 110C realizes display driving of the first color light emitting element 210 through the third via hole 200D3. Further, the first groove 310 includes a third groove division 313, and the third groove division 313 is used to expose part of the third electrode layer division 200A3, that is, the third groove division 313 is a pixel opening corresponding to the first color light emitting element 210.
[0068] Specifically, refer to Figure 3 and Fig.11As shown, the third groove section 313 includes a second side N3, and the orthographic projection of the side N4 of the third via 200D3 onto the substrate 100 is tangent to the orthographic projection of the second side N3 onto the substrate 100. In other words, the projection of the third via 200D3 onto the substrate 100 intersects with the projection of the third electrode layer section 200A3 onto the substrate 100, and the side N4 of the third via 200D3 is tangent to the second side N3. Further, the orthographic projection of the center of the third via 200D3 onto the substrate 100 is located on the side of the orthographic projection of the second side N3 onto the substrate 100 away from the center of the third groove section 313 onto the substrate 100; that is, the center of the third via 200D3 is farther away from the center of the third electrode layer section 200A3 than the second side N3. In general, the orthographic projection of the third via hole 200D3 onto the base substrate 100 overlaps with the orthographic projection of the third electrode layer portion 200A3 onto the base substrate 100 , but the orthographic projection of the third via hole 200D3 onto the base substrate 100 does not overlap with the orthographic projection of the third groove portion 313 onto the base substrate 100 .
[0069] Further, in combination with the location of the third via 200D3, the first partition unit 410 needs to avoid the first via 200D1, that is, the first partition unit 410 takes a detour in the area close to the third via 200D3, which can ensure the continuity and integrity of the first partition unit 410. Figure 3 and Fig.11 As shown, the projection onto the base substrate 100 shows that the third via 200D3 is tangent to the third groove portion 313, but the projection of the third via 200D3 does not overlap with the projection of the third groove portion 313, which proves that the setting of the third via 200D3 has no effect on the pixel opening of the first color light-emitting element 210, and the setting of the via will not affect the flatness of the pixel opening, which is beneficial to ensuring the overall display effect of the first color light-emitting element 210.
[0070] Continue to refer Figure 3 and Fig.11As shown, the first partition unit 410 includes a fifth partition sub-section 413, a sixth partition sub-section 414 and a bending portion 415. Along the second direction X2, the fifth partition sub-section 413 and the sixth partition sub-section 414 are located on both sides of the light-emitting element 200, and the bending portion 415 is connected to the sixth partition sub-section 414; the second partition unit 420 includes a seventh partition sub-section 423 and an eighth partition sub-section 424. Along the first direction X1, the seventh partition sub-section 423 is located on a side of the adjacent first color light-emitting element 210 away from the second color light-emitting element 220, and the eighth partition sub-section 424 is located on a side of the adjacent first color light-emitting element 210 close to the second color light-emitting element 220; the seventh partition division 423 is connected to the bending portion 415, the eighth partition division 424 is respectively connected to the fifth partition division 413 and the sixth partition division 414, the bending portion 415 surrounds at least part of the third via 200D3; the fifth partition division 413 includes a fourth break 413a, and the orthographic projection of the fourth break 413a along the second direction X2 is located on a side of the orthographic projection of the adjacent seventh partition division 423 along the second direction X2 close to the orthographic projection of the third electrode layer division 200A3 along the second direction X2; the orthographic projection of the third via 200D3 along the second direction X2 overlaps with the orthographic projection of the bending portion 415 along the second direction X2.
[0071] Specifically, refer to Figure 3 and Fig.11 As shown, the first partition unit 410 includes a fifth partition sub-section 413, a sixth partition sub-section 414 and a bending section 415, wherein the fifth partition sub-section 413 and the sixth partition sub-section 414 both extend along the first direction X1, and the fifth partition sub-section 413 and the sixth partition sub-section 414 are located on both sides of the light-emitting element 200 along the second direction X2, and are used to block the leakage of light-emitting elements 200 of different colors along the second direction X2, and ensure the overall display effect of the display panel 10. Further, the first partition unit 410 also includes a bending section 415, which is used to avoid the third via 200D3, and the bending section 415 is connected to the sixth partition sub-section 414, reflecting the continuity and integrity of the first partition unit 410, and reducing the leakage that may exist in different pairs of light-emitting elements 200.
[0072] For further reference, Figure 3 and Fig.11As shown, the second partition unit 420 includes a seventh partition sub-section 423 and an eighth partition sub-section 424, wherein the seventh partition sub-section 423 and the eighth partition sub-section 424 both extend along the second direction X2, and the seventh partition sub-section 423 and the eighth partition sub-section 424 are located on both sides of the first color light emitting element 210 or the second color light emitting element 420 along the second direction X2, and are used to block the leakage of different first color light emitting elements 210 and second color light emitting elements 220 along the first direction X1, so as to ensure the overall display effect of the display panel 10. Specifically, refer to Figure 3 and Fig.11 As shown, along the first direction X1, the seventh partition sub-section 423 is located on the side of the adjacent first color light emitting element 210 away from the second color light emitting element 220, and the eighth partition sub-section 424 is located on the side of the adjacent first color light emitting element 210 close to the second color light emitting element 220. In other words, the seventh partition sub-section 423 and the eighth partition sub-section 424 are alternately arranged in sequence along the first direction X1.
[0073] Furthermore, Fig.12 yes Figure 1 The fifth enlarged schematic diagram of the A area in the middle, refer to Fig.12 As shown, the seventh partition section 423 is connected to the bending section 415, and the seventh partition section 423 is also connected to the fifth partition section 413. That is, along the second direction X2, both sides of the seventh partition section 423 can be connected to the first partition unit 410. Figure 3 As shown, the seventh partition section 423 is connected to the bending portion 415, that is, along the second direction X2, one side of the seventh partition section 423 can be connected to the first partition unit 410. The connection of the seventh partition section 423 along the second direction X2 can be adaptively adjusted according to different display panels 10, reflecting the flexibility of the partition structure 400. Figure 3 and Fig.12 As shown, the eighth partition section 424 is respectively connected to the fifth partition section 413 and the sixth partition section 414, so that the first partition unit 410 and the second partition unit 420 can form a semi-enclosed structure, which is used to reduce or avoid leakage between light-emitting elements 200 of different colors, thereby ensuring the overall display effect of the display panel 10.
[0074] For further reference, Figure 3 and Fig.12As shown, the fifth partition section 413 includes a fourth break 413a, and the orthographic projection of the fourth break 413a along the second direction X2 is located on the side of the orthographic projection of the adjacent seventh partition section 423 along the second direction X2 close to the orthographic projection of the third electrode layer section 200A3 along the second direction X2. It can be understood that the setting of the fourth break 413a can ensure that the partition structure 400 surrounding the first color light emitting element 210 is a semi-enclosed structure, and thus will not affect the transmission of normal electrical signals of the first color light emitting element 210, that is, will not affect the normal display of the first color light emitting element 210.
[0075] Continue to refer Figure 3 and Fig.12 As shown, the minimum distance between the orthographic projection of the center of the third via 200D3 onto the base substrate 100 and the orthographic projection of the adjacent seventh partition division 423 onto the base substrate 100 is L7, and the minimum distance between the orthographic projection of the third electrode layer division 200A3 onto the base substrate 100 and the orthographic projection of the adjacent seventh partition division 423 onto the base substrate 100 is L8, wherein |L7-L8| / L8≤20%.
[0076] For further reference, Figure 3 and Fig.12 For specific reference Fig.12 As shown, the minimum distance between the orthographic projection of the center of the third via 200D3 onto the base substrate 100 and the orthographic projection of the adjacent seventh partition division 423 onto the base substrate 100 is L7, and the minimum distance between the orthographic projection of the third electrode layer division 200A3 onto the base substrate 100 and the orthographic projection of the adjacent seventh partition division 423 onto the base substrate 100 is L8. For L7 and L8, the following condition is satisfied: |L7-L8| / L8≤20%, and the numerical values of L7 and L8 can be the same or similar.
[0077] That is, along the first direction X1, the orthographic projection of the third via hole 200D3 onto the base substrate 100 is close to the adjacent seventh partition section 423, that is, the third via hole 200D3 is disposed close to the end of the third electrode layer section 200A3, and the third via hole 200D3 will not affect the flatness of the third electrode layer section 200A3 exposed at the third groove section 313. At the same time, the partition structure 400 can ensure the avoidance of the third via hole 200D3 by adding the bending portion 415, and can also ensure the continuity of the partition structure 400 as a whole.
[0078] Continue to refer Figure 3 , Fig.11 and Fig.12As shown, the driving circuit 110 includes a fourth driving circuit 110D; the connecting via 200D includes a fourth via 200D4, the second color light emitting element 220 includes a fourth electrode layer division 200A4, and the fourth electrode layer division 200A4 is electrically connected to the fourth driving circuit 110D through the fourth via 200D4; the first groove 310 includes a fourth groove division 314, and the fourth groove division 314 exposes at least a portion of the fourth electrode layer division 200A4; the fifth partition division 413 also includes a fifth break 413b, and the sixth partition division 414 also includes a sixth break 414a; the orthographic projection of the fifth break 413b along the second direction X2 is located on the side where the orthographic projection of the adjacent seventh partition portion 423 along the second direction X2 is close to the orthographic projection of the adjacent fourth electrode layer portion 200A4 along the second direction X2; the orthographic projection of the fourth via 200D4 along the second direction X2 at least partially overlaps with the orthographic projection of the sixth break 414a along the second direction X2; the orthographic projection of the fifth break 413b along the second direction X2 at least partially overlaps with the orthographic projection of the sixth break 414a along the second direction X2.
[0079] Among them, reference Figure 3 , Fig.11 and Fig.12 As shown, the second color light emitting element 220 includes a fourth electrode layer division 200A4, and the fourth electrode layer division 200A4 is electrically connected to the fourth driving circuit 110D through the fourth via 200D4. The fourth driving circuit 110D realizes display driving of the second color light emitting element 220 through the fourth via 200D4. Further, the first groove 310 includes a fourth groove division 314, and the fourth groove division 314 is used to expose part of the fourth electrode layer division 200A4, that is, the fourth electrode layer division 200A4 is a pixel opening corresponding to the second color light emitting element 220.
[0080] For further reference, Figure 3 and Fig.12As shown, the fifth partition section 413 further includes a fifth break 413b, and the orthographic projection of the fifth break 413b along the second direction X2 is located on the side of the orthographic projection of the adjacent seventh partition section 423 along the second direction X2 close to the orthographic projection of the adjacent fourth electrode layer section 200A4 along the second direction X2. It can be understood that the setting of the fifth break 413b can reflect that the partition structure 400 surrounding the second color light emitting element 220 is a semi-enclosed structure, and thus will not affect the transmission of normal electrical signals of the second color light emitting element 220, that is, will not affect the normal display of the first color light emitting element 210. Furthermore, the sixth partition section 414 further includes a sixth break 414a, and the orthographic projection of the fifth break 413b along the second direction X2 overlaps at least partially with the orthographic projection of the sixth break 414a along the second direction X2. It can be understood that the fifth break 413b and the sixth break 414a can better ensure the transmission of the lateral current corresponding to the second color light-emitting element 220, and ensure the lateral uniform display of the display panel 10. Among them, the fifth break 413b and the sixth break 414a can overlap in projection along the second direction X2, which can ensure the overall continuity of the second electrode layer 200C, and then ensure the display effect of the light-emitting element 200 in the display panel 10; on the other hand, it can also ensure that the overall structure of the display panel 10 has regularity, and reduce the difficulty of the process preparation of the display panel 10.
[0081] Furthermore, the orthographic projection of the fourth via hole 200D4 along the second direction X2 overlaps at least partially with the orthographic projection of the sixth break 414a along the second direction X2. Since the setting position of the fourth via hole 200D4 overlaps with the projection of the sixth break 414a along the second direction X2, the setting of the sixth partition section 414 does not need to consider the avoidance of the fourth via hole 200D4, and the setting method of the fourth via hole 200D4 is flexible. Figure 3 or Fig.12 As shown, the orthographic projection of the side of the fourth via 200D4 onto the substrate 100 can be tangent to the orthographic projection of the side of the fourth groove division 314 onto the substrate 100, and the center of the fourth via 200D4 is farther away from the center of the fourth electrode layer division 200A4 than the side of the fourth groove division 314.
[0082] Continue to refer Fig.12As shown, the orthographic projection of the fourth break 413a along the second direction X2 and the orthographic projection of the fifth break 413b along the second direction X2 are located on both sides of the orthographic projection of the adjacent seventh partition section 423 along the second direction X2; the fourth break 413a and the fifth break 413b are not connected; the minimum spacing between the orthographic projection of the center of the fourth via 200D4 onto the substrate 100 and the orthographic projection of the adjacent seventh partition section 423 onto the substrate 100 is L9, and the minimum spacing between the orthographic projection of the center of the fourth via 200D4 onto the substrate 100 and the orthographic projection of the adjacent eighth partition section 424 onto the substrate 100 is L10; wherein, |L9-L10| / L10≤20%.
[0083] For further reference, Fig.12 As shown, the fifth partition section 413 includes a fourth break 413a and a fifth break 413b, and the orthographic projection of the fourth break 413a along the second direction X2 and the orthographic projection of the fifth break 413b along the second direction X2 are located on both sides of the orthographic projection of the adjacent seventh partition section 423 along the second direction X2. Along the first direction X1, part of the fifth partition section 413 exists between the fourth break 413a and the fifth break 413b, that is, the fourth break 413a and the fifth break 413b are not connected.
[0084] For further reference, Fig.12 As shown, the minimum distance between the orthographic projection of the center of the fourth via 200D4 to the substrate 100 and the orthographic projection of the adjacent seventh partition sub-section 423 to the substrate 100 is L9, and the minimum distance between the orthographic projection of the center of the fourth via 200D4 to the substrate 100 and the orthographic projection of the adjacent eighth partition sub-section 424 to the substrate 100 is L10, and L9 and L10 satisfy: |L9-L10| / L10≤20%, and the values of L9 and L10 can be the same or similar. That is, along the first direction X1, the fourth via 200D4 is located in the middle area of the seventh partition sub-section 423 and the eighth partition sub-section 424; that is, along the orthographic projection of the second direction X2, the connecting via 200D connected to the second color light emitting element 220 is set in the relatively central area of the partition structure 400. By setting the connecting via 200D in an area close to the center, the signal received by the second color light emitting element 220 through the connecting via 200D can be ensured to be balanced as much as possible, thereby ensuring the overall display effect of the display panel 10, and the relatively central setting position is conducive to reducing the difficulty of the process preparation of the display panel 10.
[0085] Continue to refer Figure 3As shown, the fourth break 413a and the fifth break 413b are connected; the minimum distance between the orthographic projection of the center of the fourth via 200D4 onto the substrate 100 and the orthographic projection of the adjacent eighth partition section 424 onto the substrate 100 is L11, and the minimum distance between the orthographic projection of the side of the fourth electrode layer section 200A4 close to the adjacent seventh partition section 423 onto the substrate 100 and the orthographic projection of the adjacent eighth partition section 424 onto the substrate 100 is L12, wherein, |L11-L12| / L12≤20%.
[0086] For further reference, Figure 3 As shown, the fifth partition section 413 includes a fourth break 413a and a fifth break 413b, and the fourth break 413a and the fifth break 413b are connected. Figure 3 As shown in the middle area H, the fourth break 413a and the fifth break 413b surround a larger break. By connecting the fourth break 413a and the fifth break 413b, the fourth break 413a and the fifth break 413b can be prepared synchronously during the process of manufacturing the display panel 10, thereby reducing the difficulty of manufacturing the display panel 10 and reducing the process cost of the display panel 10.
[0087] For further reference, Figure 3 As shown, the minimum distance between the orthographic projection of the center of the fourth via hole 200D4 to the substrate 100 and the orthographic projection of the adjacent eighth partition sub-section 424 to the substrate 100 is L11, and the minimum distance between the orthographic projection of the side of the fourth electrode layer sub-section 200A4 close to the adjacent seventh partition sub-section 423 to the substrate 100 and the orthographic projection of the adjacent eighth partition sub-section 424 to the substrate 100 is L12, and L11 and L12 satisfy: |L11-L12| / L12≤20%, and the values of L11 and L12 can be the same or similar. In other words, the orthographic projection of the fourth via hole 200D4 to the substrate 100 is close to the side of the adjacent eighth partition sub-section 424, that is, the setting position of the fourth via hole 200D4 is flexibly adjusted according to the setting position of the fracture at the partition structure 400.
[0088] Continue to refer Figures 1 to 12 As shown, the light emission wavelength of the first color light emitting element 210 is greater than the wavelength of the second color light emitting element 220 .
[0089] Specifically, refer to Figures 1 to 12 As shown, the light emission wavelength of the first color light emitting element 210 can be greater than the light emission wavelength of the second color light emitting element 220. For example, the first color light emitting element 210 is a red light emitting element, and the second color light emitting element 220 is a green light emitting element. The specific colors of the first color light emitting element 210 and the second color light emitting element 220 can be adaptively adjusted according to the requirements of different display panels 10.
[0090] Continue to refer Figures 1 to 12 As shown, the average distance between the orthographic projection of the second partition unit 420 onto the base substrate 100 and the orthographic projection of the adjacent first color light-emitting element 210 onto the base substrate 100 is d1, and the average distance between the orthographic projection of the second partition unit 420 onto the base substrate 100 and the orthographic projection of the adjacent second color light-emitting element 220 onto the base substrate 100 is d2; wherein, |d1-d2| / d2≤20%.

In other words, the second partition unit 420 is located between the first color light emitting element 210 and the second color light emitting element 220, and the distance to the first color light emitting element 210 is similar to or the same as the distance to the second color light emitting element 220, which can evenly avoid leakage of light emitting elements 200 of different colors. At the same time, it can also reflect that the overall arrangement of the second partition unit 420 is regular, which is conducive to reducing the difficulty of the process preparation of the display panel 10.
[0092] Continue to refer Figures 1 to 3 , Figure 7 , Fig.10 and Fig.12 As shown, the light-emitting element 200 also includes a light-emitting element 230 of a third color, and the light-emitting colors of the first color light-emitting element 210, the second color light-emitting element 220 and the third color light-emitting element 230 are different; wherein, the orthographic projection of the first partition unit 410 onto the base substrate 100 is located between the orthographic projection of the adjacent first color light-emitting element 210 onto the base substrate 100 and the orthographic projection of the adjacent third color light-emitting element 230 onto the base substrate 100; the average distance between the orthographic projection of the first partition unit 410 onto the base substrate 100 and the orthographic projection of the adjacent first color light-emitting element 210 onto the base substrate 100 is d3, and the average distance between the orthographic projection of the first partition unit 410 onto the base substrate 100 and the orthographic projection of the adjacent third color light-emitting element 230 onto the base substrate is d4; wherein, |d3-d4| / d4≤20%.
[0093] For further reference, Figures 1 to 3 , Figure 7 , Fig.10 and Fig.12As shown, the light-emitting element 200 may include a first color light-emitting element 210, a second color light-emitting element 220 and a third color light-emitting element 230, and the light-emitting colors of the first color light-emitting element 210, the second color light-emitting element 220 and the third color light-emitting element 230 are different, thereby achieving a color display effect of the display panel 10.
[0094] For further reference, Fig.12 As shown, the orthographic projection of the first partition unit 410 onto the base substrate 100 is located between the orthographic projection of the adjacent first color light emitting element 210 onto the base substrate 100 and the orthographic projection of the adjacent third color light emitting element 230 onto the base substrate 100. Similarly, the orthographic projection of the first partition unit 410 onto the base substrate 100 is also located between the orthographic projection of the adjacent second color light emitting element 220 onto the base substrate 100 and the orthographic projection of the adjacent third color light emitting element 230 onto the base substrate 100.
[0095] For further reference, Figures 1 to 12 As shown, specific reference Fig.12 As shown, the average distance between the orthographic projection of the first partition unit 410 to the substrate 100 and the orthographic projection of the adjacent first color light-emitting element 210 to the substrate 100 is d3, and the average distance between the orthographic projection of the first partition unit 410 to the substrate 100 and the orthographic projection of the adjacent third color light-emitting element 230 to the substrate is d4; wherein, |d3-d4| / d4≤20%, that is, the values of d3 and d4 are the same or similar.

In this way, leakage of light-emitting elements 200 of different colors can be avoided in a balanced manner. At the same time, it can also reflect that the overall arrangement of the first partition unit 410 is regular, which is beneficial to reducing the difficulty of the process of manufacturing the display panel 10 .
[0096] Optionally, Fig.13 yes Figure 2 The third cross-sectional diagram along the section line C-C', see Fig.13 As shown, the partition structure 400 penetrates the pixel defining structure 300 .
[0097] Specifically, refer to Fig.13 As shown, the partition structure 400 may penetrate the pixel defining structure 300, thereby ensuring the extension path of the common electrode layer 200B at the partition structure 400. Figure 6As shown, the partition structure 400 may also penetrate a portion of the pixel defining structure 300 , thereby reflecting a flexible arrangement of the partition structure 400 .
[0098] Fig.14 is a schematic structural diagram of a first light-emitting element provided by an embodiment of the present invention, Fig.15 is a schematic diagram of the structure of the second light emitting element provided in an embodiment of the present invention, with reference to Fig.14 and Fig.15 As shown, the common electrode layer 200B includes at least two light-emitting film layers 200B4.
[0099] Further, the common electrode layer 200B of the light emitting element 200 includes at least two light emitting film layers 200B4. Fig.14As shown, the common electrode layer 200B may include multiple film layers. Along the direction from the first electrode layer 200A to the second electrode layer 200C, the common electrode layer 200B may be: a hole injection layer (Hole Injection Layer, HIL) 200B1, a hole transport layer (HTL) 200B2, a compensation layer (Prime) 200B3, an emitting film layer (Emitting Layer, EML) 200B4, a hole blocking layer (Hole Block Layer, HBL) 200B5, an electron transport layer (Electron Transport Layer, ETL) 200B6, and an electron injection layer (Electron Inject Layer, EIL) 200B7. Among them, corresponding to the light-emitting elements 200 of different colors, the compensation layer 200B3 includes a red compensation layer (R-Prime), a blue compensation layer (B-Prime) and a green compensation layer (G-Prime), etc., which are respectively used to adjust the cavity length of each light-emitting element 200, and then adjust the optical performance. The light-emitting film layer 200B4 includes a red light-emitting layer (R-EML), a blue light-emitting layer (B-EML) and a green light-emitting layer (G-EML), so as to achieve light-emitting effects of different colors of the light-emitting element 200. The compensation layer 200B3 and the light-emitting film layer 200B4 are stacked, and the side walls can be aligned. Specifically, the light-emitting principle of the light-emitting element 200 can be understood as follows: a certain voltage is applied to the first electrode layer 200A and the second electrode layer 200C, respectively, holes from the first electrode layer 200A are injected into the hole transport layer 200B2 through the hole injection layer 200B1, and electrons from the second electrode layer 200C are injected into the electron transport layer 200B6 through the electron injection layer 200B7, and holes and electrons migrate to the light-emitting film layer 200B4 through the hole transport layer 200B2 and the electron transport layer 200B6, respectively, and form excitons in the light-emitting film layer 200B4, and the excitons excite the light-emitting molecules in the light-emitting film layer 200B4 to emit light. Among them, the hole blocking layer 200B5 is used to block holes from passing through the light-emitting film layer 200B4 into the electron transport layer 200B6, so that holes and electrons are combined in the light-emitting film layer 200B4 to form excitons.
[0100] For further reference, Fig.15As shown, the display panel 10 can also be a tandem display panel (Tandem OLED), that is, the light-emitting element 200 is a stacked light-emitting unit, and the display panel 10 that uses the stacked light-emitting unit to emit light is called a tandem display panel, that is, multiple light-emitting layers are stacked in series through a charge generation layer (CGL) in the light-emitting element 200. Among them, the tandem display panel can enable the light-emitting element 200 to be driven at the same current density, so that the brightness of the display panel 10 is greatly improved. Specifically, when multiple light-emitting film layers 200B4 are connected in series in the light-emitting element 200 of the tandem display panel, for example, when two light-emitting film layers 200B4 are connected in series, the voltage of the second electrode layer 200C applied will become twice, the current efficiency will also become twice, and the constant current life decay is consistent, so the corresponding constant brightness life will be more than doubled, the potential for life improvement is greater, and the power consumption is also advantageous.

Fig.15 In the figure, two charge generation layers 200E are used as an example. Fig.15 A schematic diagram of the structure of a light-emitting element 200 in a tandem display panel 10 is shown. In the direction from the first electrode layer 200A to the second electrode layer 200C, the film layer structure may be a hole injection layer 200B1, a hole transport layer 200B2, a compensation layer 200B3, a light-emitting film layer 200B4, a hole blocking layer 525, an electron transport layer 526, two charge generation layers 540, a hole transport layer 522, a compensation layer 200B3, a light-emitting film layer 200B4, an electron transport layer 200B6 and an electron injection layer 200B7. Among them, the charge generation layer 200E may include a P-type charge generation layer (CGL-P) and an N-type charge generation layer (CGL-N), which are used to generate holes and electrons respectively, and a light-emitting film layer 200B4 is provided between the electron transport layer 526 and the hole transport layer 200B2, that is, the common electrode layer 200B in the light-emitting element 200 includes at least two light-emitting film layers 200B4. It should be noted that Fig.14 and Fig.15 In the embodiment, the light-emitting film layer 200B4 in the light-emitting element 200 can be a light-emitting layer of red light, a light-emitting layer of blue light, or a light-emitting layer of green light, which is not specifically limited in the embodiment of the present invention. Further, the light-emitting element 200 in the display panel 10 can also include a light-emitting layer of red light, a light-emitting layer of blue light, and a light-emitting layer of green light, and finally display white light, etc.
