Summary of the Invention

[0003] This invention provides a display panel and a display device, which improves the display effect of the display panel by adjusting the partition structure surrounding the light-emitting element.

[0004] In a first aspect, embodiments of the present invention provide a display panel, comprising:

Figures 1 to 5As shown, an embodiment of the present invention provides a display panel 10, which includes: a substrate 100, a plurality of light-emitting elements 200, the light-emitting elements 200 being located on one side of the substrate 100; the light-emitting elements 200 include a first color light-emitting element 210 and a second color light-emitting element 220, the first color light-emitting element 210 and the second color light-emitting element 220 emitting different colors, and the first color light-emitting element 210 and the second color light-emitting element 220 being arranged along a first direction X1; a pixel defining structure 300, the pixel defining structure 300 being located on one side of the substrate 100, and the pixel defining structure 300 may be located between two adjacent light-emitting elements 200; a partition structure 400, the partition structure 400 penetrating at least a portion of the pixel defining structure 300, the partition structure 400 including a first partition unit 410 and a second partition unit 420, the first... A partition unit 410 extends along a first direction X1, and a second partition unit 420 extends along a second direction X2; along the second direction X2, at least one side of the second partition unit 420 is connected to the first partition unit 410, and the first partition unit 410 and the second partition unit 420 surround a portion of the light-emitting element 200; wherein, the orthographic projection of the second partition unit 420 onto the substrate 100 is located between the orthographic projection of the first color light-emitting element 210 onto the substrate 100 and the orthographic projection of the second color light-emitting element 220 onto the substrate 100; 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; the first direction X1 and the second direction X2 intersect.

[0034] refer to Figure 1 As shown, the display panel 10 includes multiple 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 colors, such as red, green, and blue light-emitting elements. Driving the light-emitting elements 200 of different colors to emit light can achieve a color display effect for the display panel 10. 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 can be adaptively adjusted according to the different requirements of the display panel 10. It should be noted that... Figures 1 to 3As shown, light-emitting elements 200 of different colors are illustrated using 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 substrate 100. The pixel defining structure 300 can be located between two adjacent light-emitting elements 200. Different colored light-emitting elements 200 can be separated by the pixel defining structure 300.

[0036] Further reference Figures 2 to 5 As shown, the display panel 10 also includes a partition structure 400, which extends through at least a portion of the pixel defining structure 300. Figure 4 and Figure 5 The partition structure 400 is shown penetrating a portion of the pixel defining structure 300. Optionally, the partition structure 400 may partially penetrate the pixel defining structure 300, penetrate the entire pixel defining structure 300, or extend into the film layer in the substrate 100. The depth of the partition structure 400 along the direction of the display panel 10 is not specifically limited in this embodiment and can be adaptively adjusted according to actual needs. The partition structure 400 can be understood as a region with a slot at the pixel defining structure 300, and the partition structure 400 may be located between two adjacent light-emitting elements 200. The partition structure 400 can effectively alleviate leakage between light-emitting elements 200 of different colors, 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 vapor-deposited across the entire surface. The film layer that is vapor-deposited across the entire surface has an extended path at the partition structure 400, which can effectively alleviate the leakage current transmission between different light-emitting elements 200, ensure the light-emitting stability of the light-emitting element 200, and thus improve the overall display effect of the display panel 10.

[0037] For details, please 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 extending 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. (Referring to...) 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; Reference Figure 3As shown, along the second direction X2, the two 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 surround each other to form a semi-enclosed structure, surrounding a portion of the light-emitting elements 200. The semi-enclosed partition structure 400 can reduce leakage current between light-emitting elements 200 of different colors on the one hand, and on the other hand, it will not affect the normal transmission of 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 a portion 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] Further reference Figure 2 and Figure 3 As shown, the orthographic projection of the second partition unit 420 onto the substrate 100 lies between the orthographic projection of the first color light-emitting element 210 onto the substrate 100 and the orthographic projection of the second color light-emitting element 220 onto the substrate 100. In other words, as... 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] 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 color light-emitting element 220 along the first direction X1 also 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 any breaks. While ensuring that light-emitting elements 200 of different colors can be displayed normally, by adjusting the 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 effectively prevented from causing leakage between the first color light-emitting element 210 and the second color light-emitting element 220. Simultaneously, since the second partition unit 420 is a continuous integral structure, no further etching of the second partition unit 420 is required during the fabrication of the partition structure 400, which reduces the manufacturing difficulty and cost of the display panel 10.

[0040] In summary, the display panel provided in this embodiment of the invention includes a partition structure comprising 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 surrounding the light-emitting element. Furthermore, the second partition unit is located between the first color light-emitting element and the second color light-emitting element. Moreover, 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 leakage between different color light-emitting elements and further improve the overall display effect of the display panel.

[0041] Figure 6 yes Figure 2 A schematic diagram of the second type of section along section line C-C', see reference. Figures 1 to 3 , Figure 6 As shown, the substrate 100 includes a driving circuit 110, which 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 substrate 100 and is electrically connected to the driving circuit 110 through a connecting via 200D; the common electrode layer 200B is located on the side of the first electrode layer 200A away from the substrate 100, and the second electrode layer 200C is located on the side of the common electrode layer 200B away from the first electrode layer 200A; the pixel defining structure 300 includes a first groove 310, which penetrates 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 substrate 100 intersects with the orthographic projection of the first electrode layer 200A onto the substrate 100.

[0042] The substrate 100 includes a driving circuit 110, which comprises multiple transistors 111. The transistors 111 are electrically connected to the light-emitting element 200, providing driving current to the light-emitting element 200 to ensure the normal display of the display panel 10. Furthermore, the driving circuit 110 may include "4T1C", "7T1C", and "8T1C", etc., where "T" represents a transistor and "C" represents a capacitor. Figure 6 The driving circuit 110 is not specifically shown; only a transistor 111 is used as an example. Furthermore, the substrate 100 includes multiple stacked film layers, such as a substrate layer 101, a gate insulating layer 102, an interlayer insulating layer 103, and a planarizing insulating layer 104. The specific type and number of film layers in the substrate 100 can be adaptively adjusted according to different needs; this embodiment of the invention does not impose specific limitations here. Furthermore, 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 adapted according to the requirements, and the embodiments of the present invention do not impose specific limitations on this.

[0043] 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 via a connecting via 200D, thereby achieving 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. Holes from the first electrode layer 200A and electrons from the second electrode layer 200C converge in the light-emitting film layer of the common electrode layer 200B, where they are further excited to emit light, thus realizing the light emission of the light-emitting element 200. Figures 2 to 6 As shown, a partition structure 400 is provided between adjacent light-emitting elements 200. The partition structure 400 can increase the extension path of the common electrode layer 200B, which 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] Further reference Figures 2 to 6 As shown, the pixel defining structure 300 includes a first groove 310, which penetrates the pixel defining structure 300 and exposes a portion 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 defines the size of the light-emitting element 200.

[0045] In this embodiment, the orthographic projection of the connecting via 200D onto the substrate 100 overlaps with the orthographic projection of the first electrode layer 200A onto the substrate 100. For example, referring to... Figure 2 and Figure 6 As shown, the orthographic projection of the connecting via 200D onto the substrate 100 may overlap with the orthographic projection of the first groove 310 onto the substrate 100; or refer to Figure 3As shown, the orthographic projection of the connecting via 200D onto the substrate 100 and the orthographic projection of the first groove 310 onto the substrate 100 may not overlap. The specific placement of the connecting via 200D is flexible, and the partition structure 400 can be flexibly adjusted according to the specific placement 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 region A in the middle, Figure 8 yes Figure 7 A schematic diagram of the second type of section along section line D-D', see reference. 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, which is electrically connected to the first driving circuit 110A through the first via 200D1; the first groove 310 includes a first groove portion 311, which exposes at least a portion of the first electrode layer portion 200A1; the first electrode layer portion 200A1 includes a first side N1; the orthographic projection of the side N2 of the first via 200D1 onto the substrate 100 is tangent to the orthographic projection of the first side N1 onto the substrate 100; the orthographic projection of the center of the first via 200D1 onto the substrate 100 is located on the side of the orthographic projection of the first side N1 onto the substrate 100 that is close to the center of the first electrode layer portion 200A1 onto the 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 portion 200A1, which is electrically connected to the first driving circuit 110A through a first via 200D1. The first driving circuit 110A drives the display of the first color light-emitting element 210 through the first via 200D1. Further, the first recess 310 includes a first recess portion 311, which exposes a portion of the first electrode layer portion 200A1; that is, the first recess portion 311 is a pixel opening corresponding to the first color light-emitting element 210.

[0048] For details, please refer to Figure 2 , Figures 6 to 8As shown, the first electrode layer portion 200A1 includes a first side N1. The orthographic projection of the side N2 of the first via 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 200D1 onto the substrate 100 intersects with the projection of the first electrode layer portion 200A1 onto the substrate 100, and the two sides are tangent. Further, the orthographic projection of the center of the first via 200D1 onto the substrate 100 is located on the side of the orthographic projection of the first side N1 onto the substrate 100 that is closer to the orthographic projection of the center of the first electrode layer portion 200A1 onto the substrate 100; that is, the center of the first via 200D1 is close to the center of the first electrode layer portion 200A1. In general, the orthographic projection of the first via 200D1 onto the substrate 100 overlaps with the orthographic projection of the first electrode layer portion 200A1 onto the substrate 100, and the side N2 of the first via 200D1 is tangent to the first side N1 of the first electrode layer portion 200A1.

[0049] Furthermore, the position of the first via 200D1 is adjusted so that the projection of the first via 200D1 along the first direction X1 does not overlap with the projection of the first partition unit 410 along the first direction X1. In other words, the placement of the first partition unit 410 does not need to consider avoiding the first via 200D1, thus ensuring the continuity and integrity of the first partition unit 410. The continuity and integrity of the first partition unit 410 along the first direction X1 reduces the manufacturing difficulty 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, ensuring the overall display effect of the display panel 10. Similarly, the projection of the first via 200D1 along the second direction X2 also does not overlap with the projection of the second partition unit 420 along the second direction X2, further ensuring the continuity and integrity of the second partition unit.

[0050] Continue to refer to Figure 2 , Figures 4 to 8As shown, the first partition unit 410 includes a first partition portion 411 and a second partition portion 412. Along the second direction X2, the first partition portion 411 and the second partition portion 412 are located on both sides of the light-emitting element 200. The second partition unit 420 includes a third partition portion 421 and a fourth partition portion 422. Along the first direction X1, the third partition portion 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 portion 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 located on the side near the second color light-emitting element 220; the third partition portion 421 is connected to the second partition portion 412, and the fourth partition portion 422 is connected to the first partition portion 411 and the second partition portion 412 respectively; the first partition portion 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 portion 421 along the second direction X2 that is close to the orthographic projection of the first electrode layer portion 200A1 along the second direction X2.

[0051] For details, please refer to Figure 2 , Figures 4 to 8 As shown, the first partition unit 410 includes a first partition portion 411 and a second partition portion 412, wherein both the first partition portion 411 and the second partition portion 412 extend along a first direction X1, and the first partition portion 411 and the second partition portion 412 are located on both sides of the light-emitting element 200 along a second direction X2, used to block leakage of different color light-emitting elements 200 along the second direction X2, ensuring the overall display effect of the display panel 10. Further, refer to... Figure 2 , Figures 4 to 8 As shown, the second partition unit 420 includes a third partition portion 421 and a fourth partition portion 422, wherein both the third partition portion 421 and the fourth partition portion 422 extend along the second direction X2, and are located on both sides of the first color light-emitting element 210 or the second color light-emitting element 220 along the second direction X2, for blocking leakage between the different first color light-emitting elements 210 and the second color light-emitting element 220 along the first direction X1, thus ensuring 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 portion 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 portion 422 is located on the side of the adjacent first color light-emitting element 210 closer to the second color light-emitting element 220. In other words, the third partition portion 421 and the fourth partition portion 422 are arranged alternately along the first direction X1.

[0052] Among them, reference Figure 2As shown, the third partition portion 421 is connected to the second partition portion 412, and also to the first partition portion 411. That is, along the second direction X2, both sides of the third partition portion 421 can be connected to the first partition unit 410. Alternatively, refer to... Figure 7 As shown, the third partition section 421 is connected to the second partition section 412, that is, along the second direction X2, one side of the third partition section 421 can be connected to the first partition unit 410. The connection of the third partition section 421 along the second direction X2 can be adaptively adjusted according to different display panels 10, demonstrating the flexibility of the partition structure 400. Further, refer to... 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. This demonstrates 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 different color light-emitting elements 200, thereby ensuring the overall display effect of the display panel 10.

[0053] Further reference Figure 2 and Figure 7 As shown, the first partition portion 411 includes a first break 411a. 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 portion 421 along the second direction X2 that is closer to the orthographic projection of the first electrode layer portion 200A1 along the second direction X2. This can be understood as the arrangement of the first break 411a ensuring that the partition structure 400 surrounding the first color light-emitting element 210 is a semi-enclosed structure, thus not affecting the normal electrical signal transmission of the first color light-emitting element 210, i.e., not affecting the normal display of the first color light-emitting element 210.

[0054] Continue to refer to Figure 2 and Figure 7 As shown, the minimum distance between the orthographic projection of the center of the first via 200D1 onto the substrate 100 and the orthographic projection of the adjacent third partition portion 421 onto the substrate 100 is L1, and the minimum distance between the orthographic projection of the center of the first via 200D1 onto the substrate 100 and the orthographic projection of the adjacent fourth partition portion 422 onto the substrate 100 is L2; ​​wherein, |L1-L2| / L2≤20%.

[0055] Further reference Figure 2 and Figure 7 As shown, please refer to the following for details. Figure 2As shown, the minimum distance between the orthographic projection of the center of the first via 200D1 onto the substrate 100 and the orthographic projection of the adjacent third partition portion 421 onto the substrate 100 is L1, and the distance between the orthographic projection of the center of the first via 200D1 onto the substrate 100 and the orthographic projection of the adjacent fourth partition portion 422 onto the substrate 100 is L2. For L1 and L2, the following condition is met: |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 region between the third partition portion 421 and the fourth partition portion 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 region of the partition structure 400. By placing the connection via 200D in a region close to the center, the signal received by the first color light-emitting element 210 through the connection via 200D can be made as balanced as possible, thereby ensuring the overall display effect of the display panel 10. Furthermore, the relatively central placement position helps to reduce the manufacturing difficulty of the display panel 10.

[0056] Figure 9 yes Figure 2 A schematic diagram of a section along the central section line E-E', please refer to... Figure 2 , Figure 3 , Figure 7 and Figure 9 As shown, the driving circuit 110 includes a second driving circuit 110B; the connecting via 200D includes a second via 200D2; the second color light-emitting element 220 includes a second electrode layer portion 200A2, which is electrically connected to the second driving circuit 110B through the second via 200D2; the first groove 310 includes a second groove portion 312, which exposes at least a portion of the second electrode layer portion 200A2; the first partition portion 411 also includes a second break 411b, which... 412 also includes a third fracture 412a; the orthographic projection of the second fracture 411b along the second direction X2 is located on the side of the orthographic projection of the adjacent third partition portion 421 along the second direction X2 close to the orthographic projection of the adjacent second electrode layer portion 200A2 along the second direction X2; the orthographic projection of the second via 200D2 along the second direction X2 at least partially overlaps with the orthographic projection of the third fracture 412a along the second direction X2; the orthographic projection of the second fracture 411b along the second direction X2 at least partially overlaps with the orthographic projection of the third fracture 412a along the second direction X2.

[0057] Among them, reference Figure 2 , Figure 3 , Figure 7 and Figure 9As shown, the second color light-emitting element 220 includes a second electrode layer portion 200A2, which is electrically connected to the second driving circuit 110B through a second via 200D2. The second driving circuit 110B drives the display of the second color light-emitting element 220 through the second via 200D2. Further, the first groove 310 includes a second groove portion 312, which exposes a portion of the second electrode layer portion 200A2; that is, the second electrode layer portion 200A2 is the pixel opening corresponding to the second color light-emitting element 220.

[0058] Further reference Figure 2 and Figure 7 As shown, the first partition portion 411 also includes a second break 411b. The orthographic projection of the second break 411b along the second direction X2 is located on the side of the orthographic projection of the adjacent third partition portion 421 along the second direction X2 that is close to the orthographic projection of the adjacent second electrode layer portion 200A2 along the second direction X2. This can be understood as the arrangement of the second break 411b ensuring that the partition structure 400 surrounding the second color light-emitting element 220 is a semi-enclosed structure, thus not affecting the normal electrical signal transmission of the second color light-emitting element 220, i.e., not affecting the normal display of the first color light-emitting element 210. Furthermore, the second partition portion 412 also includes a third break 412a. The orthographic projection of the second break 411b along the second direction X2 and the orthographic projection of the third break 412a along the second direction X2 at least partially overlap. This can be understood as the second break 411b and the third break 412a both better ensuring the transmission of the lateral current corresponding to the second color light-emitting element 220, thus ensuring the lateral uniformity of the display panel 10. The overlapping projections of the second break 411b and the third break 412a along the second direction X2 ensure, on the one hand, the overall continuity of the second electrode layer 200C, thereby ensuring the display effect of the light-emitting element 200 in the display panel 10; on the other hand, it also ensures the regularity of the overall structure of the display panel 10, reducing the manufacturing difficulty of the display panel 10.

[0059] Furthermore, the orthographic projection of the second via 200D2 along the second direction X2 at least partially overlaps with the orthographic projection of the third fracture 412a along the second direction X2. Since the placement of the second via 200D2 overlaps with the projection of the third fracture 412a along the second direction X2, the placement of the second partition portion 412 does not need to consider avoiding the second via 200D2, allowing for flexibility in the placement of the second via 200D2. Figure 2 or Figure 7As shown, the orthographic projection of the side of the second via 200D2 onto the substrate 100 is tangent to the orthographic projection of the side of the second electrode layer portion 200A2 onto the substrate 100, and the center of the second via 200D2 is closer to the center of the second electrode layer portion 200A2 than the side of the second electrode layer portion 200A2. Optionally, Figure 10 yes Figure 1 The fourth enlarged diagram of region A in the middle, for reference. Figure 10 As shown, the orthographic projection of the side of the second via 200D2 onto the substrate 100 is 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 further away from the center of the second electrode layer portion 200A2 than the side of the second groove portion 312.

[0060] Continue to refer to Figure 2 As shown, the orthographic projection of the first fracture 411a along the second direction X2 and the orthographic projection of the second fracture 411b along the second direction X2 are located on both sides of the orthographic projection of the adjacent third partition portion 421 along the second direction X2; the first fracture 411a and the second fracture 411b are not 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 portion 421 onto the substrate 100 is L3, and 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 fourth partition portion 422 onto the substrate 100 is L4; wherein, |L3-L4| / L4≤20%.

[0061] Further reference Figure 2 As shown, the first partition segment 411 includes a first fracture 411a and a second fracture 411b. The orthographic projections of the first fracture 411a and the second fracture 411b along the second direction X2 are located on both sides of the orthographic projections of the adjacent third partition segment 421 along the second direction X2. Along the first direction X1, there is a portion of the first partition segment 411 between the first fracture 411a and the second fracture 411b, that is, the first fracture 411a and the second fracture 411b are not connected.

[0062] Further reference Figure 2As shown, 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 portion 421 onto the substrate 100 is L3, and 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 fourth partition portion 422 onto the substrate 100 is L4. For L3 and L4, the following condition is met: |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 region between the third partition portion 421 and the fourth partition portion 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 region of the partition structure 400. By placing the connection via 200D in a region close to the center, the signal received by the second color light-emitting element 220 through the connection via 200D can be made as balanced as possible, thereby ensuring the overall display effect of the display panel 10. Furthermore, the relatively central placement position helps to reduce the manufacturing difficulty of the display panel 10.

[0063] Continue to refer to 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 portion 421 onto the substrate 100 is L5, and the minimum distance between the orthographic projection of the side of the second electrode layer portion 200A2 near the adjacent third partition portion 421 onto the substrate 100 and the orthographic projection of the adjacent third partition portion 421 onto the substrate 100 is L6, wherein |L5-L6| / L6≤20%.

[0064] Further reference Figure 7 As shown, the first partition portion 411 includes a first break 411a and a second break 411b, and the first break 411a and the second break 411b are connected, as shown in the reference. Figure 7 As shown in region F, the first fracture 411a and the second fracture 411b form a larger fracture. By connecting the first fracture 411a and the second fracture 411b, the first fracture 411a and the second fracture 411b can be prepared simultaneously during the manufacturing process of the display panel 10, reducing the manufacturing difficulty and cost of the display panel 10.

[0065] Further reference Figure 7As shown, 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 portion 421 onto the substrate 100 is L5. The minimum distance between the orthographic projection of the side of the second electrode layer portion 200A2 near the adjacent third partition portion 421 onto the substrate 100 and the orthographic projection of the adjacent third partition portion 421 onto the substrate 100 is L6. For L5 and L6, the following condition is met: |L5-L6| / L6≤20%. The values ​​of L5 and L6 can be the same or similar. That is to say, the orthographic projection of the second via 200D2 onto the substrate 100 is closer to the side of the adjacent third partition portion 421. In other words, the setting position of the second via 200D2 can be flexibly adjusted according to the setting position of the break at the partition structure 400.

[0066] Figure 11 yes Figure 3 A schematic diagram of a cross-section along section line G-G', for reference. Figure 3 and Figure 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, which is electrically connected to the third driving circuit 110C through the third via 200D3; the first groove 310 includes a third groove portion 313, which 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 100 is tangent to the orthographic projection of the second side N3 onto the substrate 100; 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 that is away from the orthographic projection of the center of the third groove portion 313 onto the substrate 100.

[0067] Among them, reference Figure 3 and Figure 11 As shown, the first color light-emitting element 210 includes a third electrode layer portion 200A3, which is electrically connected to the third driving circuit 110C through a third via 200D3. The third driving circuit 110C drives the first color light-emitting element 210 through the third via 200D3. Furthermore, the first recess 310 includes a third recess portion 313, which exposes a portion of the third electrode layer portion 200A3; that is, the third recess portion 313 is a pixel opening corresponding to the first color light-emitting element 210.

[0068] For details, please refer to Figure 3 and Figure 11As shown, the third recess portion 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 the projection of the third electrode layer portion 200A3 onto the substrate 100, and the side N4 of the third via 200D3 is tangent to the second side N3. Furthermore, 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 that is away from the orthographic projection of the center of the third recess portion 313 onto the substrate 100; that is, the center of the third via 200D3 is farther from the center of the third electrode layer portion 200A3 than the second side N3. In general, the orthographic projection of the third via 200D3 onto the substrate 100 overlaps with the orthographic projection of the third electrode layer portion 200A3 onto the substrate 100, but the orthographic projection of the third via 200D3 onto the substrate 100 does not overlap with the orthographic projection of the third groove portion 313 onto the substrate 100.

[0069] Furthermore, considering 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 uses a detour in the area near the third via 200D3 to ensure the continuity and integrity of its installation. (Reference) Figure 3 and Figure 11 As shown, the projection onto the 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. This proves that the setting of the third via 200D3 has no effect on the pixel opening of the first color light-emitting element 210. The via setting method 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 to Figure 3 and Figure 11As shown, the first partition unit 410 includes a fifth partition portion 413, a sixth partition portion 414, and a bent portion 415. Along the second direction X2, the fifth partition portion 413 and the sixth partition portion 414 are located on both sides of the light-emitting element 200, and the bent portion 415 is connected to the sixth partition portion 414. The second partition unit 420 includes a seventh partition portion 423 and an eighth partition portion 424. Along the first direction X1, the seventh partition portion 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 portion 424 is located on the side of the adjacent first color light-emitting element 210 close to the second color light-emitting element. On one side of 220; the seventh partition portion 423 is connected to the bending portion 415, the eighth partition portion 424 is connected to the fifth partition portion 413 and the sixth partition portion 414 respectively, the bending portion 415 surrounds at least part of the third through hole 200D3; the fifth partition portion 413 includes a fourth break 413a, 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 portion 423 along the second direction X2 close to the orthographic projection of the third electrode layer portion 200A3 along the second direction X2; the orthographic projection of the third through hole 200D3 along the second direction X2 overlaps with the orthographic projection of the bending portion 415 along the second direction X2.

[0071] For details, please refer to Figure 3 and Figure 11 As shown, the first partition unit 410 includes a fifth partition portion 413, a sixth partition portion 414, and a bending portion 415. The fifth partition portion 413 and the sixth partition portion 414 both extend along the first direction X1, and are located on both sides of the light-emitting element 200 along the second direction X2. This serves to block leakage from different colored light-emitting elements 200 along the second direction X2, ensuring the overall display effect of the display panel 10. Furthermore, the first partition unit 410 also includes a bending portion 415, which is used to avoid the third through-hole 200D3. The bending portion 415 is connected to the sixth partition portion 414, demonstrating the continuity and integrity of the first partition unit 410 and reducing potential leakage from different pairs of light-emitting elements 200.

[0072] Further reference Figure 3 and Figure 11As shown, the second partition unit 420 includes a seventh partition portion 423 and an eighth partition portion 424, both of which extend along the second direction X2. These portions are located on either side of the first color light-emitting element 210 or the second color light-emitting element 220 along the second direction X2, serving to block leakage between the first and second color light-emitting elements 210 and 220 along the first direction X1, thus ensuring the overall display effect of the display panel 10. Specifically, refer to... Figure 3 and Figure 11 As shown, along the first direction X1, the seventh partition portion 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 portion 424 is located on the side of the adjacent first color light-emitting element 210 closer to the second color light-emitting element 220. In other words, the seventh partition portion 423 and the eighth partition portion 424 are arranged alternately along the first direction X1.

[0073] Furthermore, Figure 12 yes Figure 1 The fifth enlarged diagram of region A in the middle, for reference. Figure 12 As shown, the seventh partition portion 423 is connected to the bent portion 415, and also to the fifth partition portion 413. That is, along the second direction X2, both sides of the seventh partition portion 423 can be connected to the first partition unit 410. Alternatively, refer to... Figure 3 As shown, the seventh partition portion 423 is connected to the bent portion 415, that is, along the second direction X2, one side of the seventh partition portion 423 can be connected to the first partition unit 410. The connection of the seventh partition portion 423 along the second direction X2 can be adaptively adjusted according to different display panels 10, demonstrating the flexibility of the partition structure 400. Further, refer to... Figure 3 and Figure 12 As shown, the eighth partition section 424 is connected to the fifth partition section 413 and the sixth partition section 414 respectively. This allows the first partition unit 410 and the second partition unit 420 to form a semi-enclosed structure, which reduces or avoids leakage between different color light-emitting elements 200, thereby ensuring the overall display effect of the display panel 10.

[0074] Further reference Figure 3 and Figure 12As shown, the fifth partition portion 413 includes a fourth break 413a. 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 portion 423 along the second direction X2 that is closer to the orthographic projection of the third electrode layer portion 200A3 along the second direction X2. This can be understood as the arrangement of the fourth break 413a ensuring that the partition structure 400 surrounding the first color light-emitting element 210 is a semi-enclosed structure, thus not affecting the normal electrical signal transmission of the first color light-emitting element 210, i.e., not affecting the normal display of the first color light-emitting element 210.

[0075] Continue to refer to Figure 3 and Figure 12 As shown, the minimum distance between the orthographic projection of the center of the third via 200D3 onto the substrate 100 and the orthographic projection of the adjacent seventh partition portion 423 onto the substrate 100 is L7, and the minimum distance between the orthographic projection of the third electrode layer portion 200A3 onto the substrate 100 and the orthographic projection of the adjacent seventh partition portion 423 onto the substrate 100 is L8, wherein |L7-L8| / L8≤20%.

[0076] Further reference Figure 3 and Figure 12 For details, please refer to the following: Figure 12 As shown, the minimum distance between the orthographic projection of the center of the third via 200D3 onto the substrate 100 and the orthographic projection of the adjacent seventh partition portion 423 onto the substrate 100 is L7, and the minimum distance between the orthographic projection of the third electrode layer portion 200A3 onto the substrate 100 and the orthographic projection of the adjacent seventh partition portion 423 onto the substrate 100 is L8. For L7 and L8, the following condition is met: |L7-L8| / L8≤20%, and the values ​​of L7 and L8 can be the same or similar.

[0077] In other words, along the first direction X1, the orthogonal projection of the third via 200D3 onto the substrate 100 is close to the adjacent seventh partition portion 423. That is, the location of the third via 200D3 is close to the end of the third electrode layer portion 200A3, and the third via 200D3 will not affect the flatness of the third electrode layer portion 200A3 exposed at the third groove portion 313. At the same time, the partition structure 400 can avoid the third via 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 to Figure 3 , Figure 11 and Figure 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 portion 200A4, which is electrically connected to the fourth driving circuit 110D through the fourth via 200D4; the first groove 310 includes a fourth groove portion 314, which exposes at least a portion of the fourth electrode layer portion 200A4; the fifth partition portion 413 further includes a fifth break 413b; and the sixth partition portion... 414 also includes a sixth fracture 414a; the orthographic projection of the fifth fracture 413b along the second direction X2 is located on the side of the orthographic projection of the adjacent seventh partition portion 423 along the second direction X2 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 fracture 414a along the second direction X2; the orthographic projection of the fifth fracture 413b along the second direction X2 at least partially overlaps with the orthographic projection of the sixth fracture 414a along the second direction X2.

[0079] Among them, reference Figure 3 , Figure 11 and Figure 12 As shown, the second color light-emitting element 220 includes a fourth electrode layer portion 200A4, which is electrically connected to the fourth driving circuit 110D through a fourth via 200D4. The fourth driving circuit 110D drives the display of the second color light-emitting element 220 through the fourth via 200D4. Furthermore, the first recess 310 includes a fourth recess portion 314, which exposes a portion of the fourth electrode layer portion 200A4; that is, the fourth electrode layer portion 200A4 serves as a pixel opening corresponding to the second color light-emitting element 220.

[0080] Further reference Figure 3 and Figure 12As shown, the fifth partition portion 413 also includes a fifth break 413b. 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 portion 423 along the second direction X2 that is close to the orthographic projection of the adjacent fourth electrode layer portion 200A4 along the second direction X2. This can be understood as the arrangement of the fifth break 413b ensuring that the partition structure 400 surrounding the second color light-emitting element 220 is a semi-enclosed structure, thus not affecting the normal electrical signal transmission of the second color light-emitting element 220, i.e., not affecting the normal display of the first color light-emitting element 210. Furthermore, the sixth partition portion 414 also includes a sixth break 414a. The orthographic projection of the fifth break 413b along the second direction X2 and the orthographic projection of the sixth break 414a along the second direction X2 at least partially overlap. This can be understood as the fifth break 413b and the sixth break 414a both better ensuring the transmission of the lateral current corresponding to the second color light-emitting element 220, thus ensuring the lateral uniformity of the display panel 10. The overlapping projections of the fifth break 413b and the sixth break 414a along the second direction X2 ensure, on the one hand, the overall continuity of the second electrode layer 200C, thereby ensuring the display effect of the light-emitting element 200 in the display panel 10; on the other hand, it also ensures the regularity of the overall structure of the display panel 10, reducing the manufacturing difficulty of the display panel 10.

[0081] Furthermore, the orthographic projection of the fourth via 200D4 along the second direction X2 at least partially overlaps with the orthographic projection of the sixth fracture 414a along the second direction X2. Since the placement of the fourth via 200D4 overlaps with the projection of the sixth fracture 414a along the second direction X2, the placement of the sixth partition portion 414 does not need to consider avoiding the fourth via 200D4, allowing for flexibility in the placement of the fourth via 200D4. Figure 3 or Figure 12 As shown, the orthographic projection of the side of the fourth via 200D4 onto the substrate 100 is tangent to the orthographic projection of the side of the fourth groove portion 314 onto the substrate 100, and the center of the fourth via 200D4 is further away from the center of the fourth electrode layer portion 200A4 than the side of the fourth groove portion 314.

[0082] Continue to refer to Figure 12As shown, the orthographic projection of the fourth fracture 413a along the second direction X2 and the orthographic projection of the fifth fracture 413b along the second direction X2 are located on both sides of the orthographic projection of the adjacent seventh partition portion 423 along the second direction X2; the fourth fracture 413a and the fifth fracture 413b are not 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 seventh partition portion 423 onto the substrate 100 is L9, and 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 portion 424 onto the substrate 100 is L10; wherein, |L9-L10| / L10≤20%.

[0083] Further reference Figure 12 As shown, the fifth partition segment 413 includes a fourth fracture 413a and a fifth fracture 413b. The orthographic projections of the fourth fracture 413a and the fifth fracture 413b along the second direction X2 are located on either side of the orthographic projections of the adjacent seventh partition segment 423 along the second direction X2. Along the first direction X1, a portion of the fifth partition segment 413 exists between the fourth fracture 413a and the fifth fracture 413b; that is, the fourth fracture 413a and the fifth fracture 413b are not connected.

[0084] Further reference Figure 12 As shown, 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 seventh partition portion 423 onto the substrate 100 is L9, and 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 portion 424 onto the substrate 100 is L10. For L9 and L10, the following condition is met: |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 region between the seventh partition portion 423 and the eighth partition portion 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 region of the partition structure 400. By placing the connection via 200D in a region close to the center, the signal received by the second color light-emitting element 220 through the connection via 200D can be made as balanced as possible, thereby ensuring the overall display effect of the display panel 10. Furthermore, the relatively central placement position helps to reduce the manufacturing difficulty of the display panel 10.

[0085] Continue to refer to 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 portion 424 onto the substrate 100 is L11; the minimum distance between the orthographic projection of the side of the fourth electrode layer portion 200A4 near the adjacent seventh partition portion 423 onto the substrate 100 and the orthographic projection of the adjacent eighth partition portion 424 onto the substrate 100 is L12, wherein |L11-L12| / L12≤20%.

[0086] Further reference Figure 3 As shown, the fifth partition portion 413 includes a fourth break 413a and a fifth break 413b, and the fourth break 413a and the fifth break 413b are connected, as shown in the reference. Figure 3 As shown in region H, the fourth fracture 413a and the fifth fracture 413b form a larger fracture. By connecting the fourth fracture 413a and the fifth fracture 413b, they can be fabricated simultaneously during the manufacturing process of the display panel 10, reducing the difficulty and cost of manufacturing the display panel 10.

[0087] Further reference Figure 3 As shown, 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 portion 424 onto the substrate 100 is L11. The minimum distance between the orthographic projection of the side of the fourth electrode layer portion 200A4 near the adjacent seventh partition portion 423 onto the substrate 100 and the orthographic projection of the adjacent eighth partition portion 424 onto the substrate 100 is L12. For L11 and L12, the following condition must be met: |L11-L12| / L12≤20%. The values ​​of L11 and L12 can be the same or similar. In other words, the orthographic projection of the fourth via 200D4 onto the substrate 100 is closer to the side of the adjacent eighth partition portion 424. That is, the setting position of the fourth via 200D4 can be flexibly adjusted according to the setting position of the break at the partition structure 400.

[0088] Continue to refer to Figures 1 to 12 As shown, the wavelength of light emitted by the first color light-emitting element 210 is greater than the wavelength of the second color light-emitting element 220.

[0089] For details, please refer to Figures 1 to 12 As shown, the light emission wavelength of the first color light-emitting element 210 can be greater than that 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 needs of different display panels 10.

[0090] Continue to refer to Figures 1 to 12 As shown, the average distance between the orthographic projection of the second partition unit 420 onto the substrate 100 and the orthographic projection of the adjacent first color light-emitting element 210 onto the substrate 100 is d1, and the average distance between the orthographic projection of the second partition unit 420 onto the substrate 100 and the orthographic projection of the adjacent second color light-emitting element 220 onto the substrate 100 is d2; wherein, |d1-d2| / d2≤20%.

[0091] Further, see reference Figures 1 to 12 As shown, please refer to the following for details. Figure 12 As shown, the average distance between the orthographic projection of the second partition unit 420 onto the substrate 100 and the orthographic projection of the adjacent first color light-emitting element 210 onto the substrate 100 is d1, and the average distance between the orthographic projection of the second partition unit 420 onto the substrate 100 and the orthographic projection of the adjacent second color light-emitting element 220 onto the substrate 100 is d2. Furthermore, d1 and d2 satisfy the condition: |d1-d2| / d2≤20%, meaning that the values ​​of d1 and d2 are the same or similar. 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 from different color light-emitting elements 200. Simultaneously, it also demonstrates the overall regularity of the second partition unit 420, which helps reduce the manufacturing difficulty of the display panel 10.

[0092] Continue to refer to Figures 1 to 3 , Figure 7 , Figure 10 and Figure 12 As shown, the light-emitting element 200 also includes a third-color light-emitting element 230, and the first-color light-emitting element 210, the second-color light-emitting element 220, and the third-color light-emitting element 230 emit different colors; wherein, the orthographic projection of the first partition unit 410 onto the substrate 100 is located between the orthographic projections of the adjacent first-color light-emitting element 210 onto the substrate 100 and the orthographic projections of the adjacent third-color light-emitting element 230 onto the substrate 100; the average distance between the orthographic projection of the first partition unit 410 onto the substrate 100 and the orthographic projection of the adjacent first-color light-emitting element 210 onto the substrate 100 is d3, and the average distance between the orthographic projection of the first partition unit 410 onto the substrate 100 and the orthographic projection of the adjacent third-color light-emitting element 230 onto the substrate 100 is d4; wherein, |d3-d4| / d4≤20%.

[0093] Further reference Figures 1 to 3 , Figure 7 , Figure 10 and Figure 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 first color light-emitting element 210, the second color light-emitting element 220 and the third color light-emitting element 230 emit different colors, thereby realizing the color display effect of the display panel 10.

[0094] Further reference Figure 12 As shown, the orthographic projection of the first partition unit 410 onto the substrate 100 is located between the orthographic projections of the adjacent first color light-emitting element 210 onto the substrate 100 and the orthographic projections of the adjacent third color light-emitting element 230 onto the substrate 100. Similarly, the orthographic projection of the first partition unit 410 onto the substrate 100 is also located between the orthographic projections of the adjacent second color light-emitting element 220 onto the substrate 100 and the orthographic projections of the adjacent third color light-emitting element 230 onto the substrate 100.

[0095] Further, see reference Figures 1 to 12 As shown, please refer to the following for details. Figure 12 As shown, the average distance between the orthographic projection of the first partition unit 410 onto the substrate 100 and the orthographic projection of the adjacent first color light-emitting element 210 onto the substrate 100 is d3, and the average distance between the orthographic projection of the first partition unit 410 onto the substrate 100 and the orthographic projection of the adjacent third color light-emitting element 230 onto the substrate is d4; wherein, |d3-d4| / d4≤20%, that is, the values ​​of d3 and d4 are the same or similar. In other words, the first partition unit 410 is located between the first color light-emitting element 210 and the third color light-emitting element 230, and the distance to the first color light-emitting element 210 is similar to or the same as the distance to the third color light-emitting element 230; similarly, the first partition unit 410 is located between the second color light-emitting element 220 and the third color light-emitting element 230, and the distance to the second color light-emitting element 220 is similar to or the same as the distance to the third color light-emitting element 230. This can evenly avoid leakage from different color light-emitting elements 200. At the same time, it can also reflect that the overall arrangement of the first partition unit 410 is regular, which helps to reduce the difficulty of manufacturing the display panel 10.

[0096] Optionally, Figure 13 yes Figure 2 A schematic diagram of the third section along section line C-C', see reference. Figure 13 As shown, the partition structure 400 penetrates the pixel-limiting structure 300.

[0097] For details, please refer to Figure 13 As shown, the partition structure 400 can penetrate the pixel-defining structure 300, thereby ensuring the extension path of the common electrode layer 200B at the partition structure 400. Further, refer to... Figure 6As shown, the partition structure 400 can also extend through part of the pixel-limiting structure 300, thus demonstrating the flexible setting method of the partition structure 400.

[0098] Figure 14 This is a schematic diagram of the structure of the first light-emitting element provided in the embodiment of the present invention. Figure 15 This is a schematic diagram of the structure of the second type of light-emitting element provided in the embodiment of the present invention, for reference. Figure 14 and Figure 15 As shown, the common electrode layer 200B includes at least two light-emitting film layers 200B4.

[0099] Furthermore, the common electrode layer 200B of the light-emitting element 200 includes at least two light-emitting film layers 200B4. For example, refer to... Figure 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 sequentially be: Hole Injection Layer (HIL) 200B1, Hole Transport Layer (HTL) 200B2, Prime Layer 200B3, Emitting Layer (EML) 200B4, Hole Block Layer (HBL) 200B5, Electron Transport Layer (ETL) 200B6, and Electron Injection Layer (EIL) 200B7. The compensation layer 200B3, corresponding to the light-emitting elements 200 of different colors, includes a red compensation layer (R-Prime), a blue compensation layer (B-Prime), and a green compensation layer (G-Prime), which are used to adjust the cavity length of each light-emitting element 200 and thus 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), thereby achieving the light-emitting effect of different colors of the light-emitting elements 200. The compensation layer 200B3 and the light-emitting film layer 200B4 are stacked and their sidewalls 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. Holes and electrons migrate to the light-emitting film layer 200B4 through the hole transport layer 200B2 and the electron transport layer 200B6 respectively, forming excitons in the light-emitting film layer 200B4. These excitons excite the light-emitting molecules in the light-emitting film layer 200B4, causing it to emit light. The hole blocking layer 200B5 is used to prevent holes from entering the electron transport layer 200B6 through the light-emitting film layer 200B4, so that holes and electrons combine in the light-emitting film layer 200B4 to form excitons.

[0100] Further reference Figure 15As shown, the display panel 10 can also be a tandem OLED display panel, where the light-emitting element 200 is a stacked light-emitting unit. A display panel 10 that uses stacked light-emitting units to emit light is called a tandem OLED display panel, meaning that multiple light-emitting layers in the light-emitting element 200 are connected in series through a charge generation layer (CGL). The tandem OLED display panel allows the light-emitting elements 200 to be driven at the same current density, thus significantly improving the brightness of the display panel 10. Specifically, when multiple light-emitting film layers 200B4 are connected in series in the light-emitting element 200 of the tandem OLED display panel, for example, two light-emitting film layers 200B4, the applied voltage to the second electrode layer 200C will double, the current efficiency will also double, and the constant current lifetime decay will be consistent. Therefore, the corresponding constant brightness lifetime will be more than doubled, with greater potential for lifetime improvement, while also offering advantages in power consumption.

[0101] Specifically, when the display panel 10 is a series display panel, such as Figure 15 As shown, multiple film layers are stacked sequentially, with charge generation layers 200E electrically connected between the film layers. Figure 15 The example shown uses two charge generation layers 200E. Further, Figure 15 A schematic diagram of the structure of a light-emitting element 200 in a series display panel 10 is shown. Along the direction from the first electrode layer 200A to the second electrode layer 200C, the film structure can sequentially include 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. The charge generation layer 200E can include a P-type charge generation layer (CGL-P) and an N-type charge generation layer (CGL-N) for generating holes and electrons, respectively. A light-emitting film layer 200B4 is disposed between the electron transport layer 526 and the hole transport layer 200B2, meaning that 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, Figure 14 and Figure 15 In this embodiment, the light-emitting film layer 200B4 in the light-emitting element 200 can be a red light-emitting layer, a blue light-emitting layer, or a green light-emitting layer; however, this embodiment does not impose a specific limitation on this. Furthermore, the light-emitting element 200 in the display panel 10 can also simultaneously include a red light-emitting layer, a blue light-emitting layer, and a green light-emitting layer, ultimately displaying white light, etc.

[0102] In the embodiment of the present invention, the light-emitting element 200 in the display panel 10 can be as follows: Figure 14 The light-emitting element 200 shown can also be as follows: Figure 15 The light-emitting element 200 shown in this embodiment of the invention does not impose specific limitations on the specific structure of the light-emitting element 200. The film layer in the light-emitting element 200 can be adaptively adjusted according to different actual needs.

[0103] Based on the same inventive concept, embodiments of the present invention also provide a display device.
