[0073] The first electrode layer 600 comprises a first sub-electrode 610 and a second sub-electrode 620 arranged at intervals, the first sub-electrode 610 being disposed on a side of the first type of light-emitting unit 510 away from the substrate 100, the second sub-electrode 620 being disposed on a side of the second type of light-emitting unit 520 away from the substrate 100, and the first sub-electrode 610 and the second sub-electrode 620 can be respectively connected with the conductive structure 410 of the isolation structure 400, so that adjacent first sub-electrodes 610 and second sub-electrodes 620 can be electrically connected through the conductive structure 410, thereby facilitating control of the first electrode layer 600 in the display panel 10 and reducing the control difficulty of the display panel 10.

[0074] Optionally, the material of the conductive structure 410 can comprise a conductive material, for example, the material of the conductive structure 410 can comprise at least one of aluminum and molybdenum, so that the first electrode layer 600 of the corresponding part of adjacent sub-pixels can be electrically connected through the conductive structure 410. For example, the first sub-electrode 610 and the second sub-electrode 620 can be electrically connected through the conductive structure 410.

[0075] The first type of light-emitting unit 510 has a first thickness, the second type of light-emitting unit 520 has a second thickness, and the first thickness is greater than the second thickness.

[0076] Optionally, the first thickness can be an average thickness of the first light emitting unit 510 at a position where the first light emitting unit 510 overlaps with the conductive structure 410, or the first thickness can be an average thickness of the first light emitting unit 510, or the first thickness can be a maximum thickness of the first light emitting unit 510.

[0077] Optionally, the second thickness can be an average thickness of the second light emitting unit 520 at a position where the second light emitting unit 520 overlaps with the conductive structure 410, or the second thickness can be an average thickness of the second light emitting unit 520, or the second thickness can be a maximum thickness of the second light emitting unit 520.

[0078] By setting the overlap width between the first light emitting unit 510 and the conductive structure 410 to be smaller than the overlap width between the second light emitting unit 520 and the conductive structure 410, the first light emitting unit 510 with a larger thickness is less likely to cover the conductive structure 410 excessively compared with the second light emitting unit 520 with a smaller thickness, so that the first light emitting unit 510 with a larger thickness is less likely to cause excessive shielding effect on the overlap between the first sub-electrode 610 and the conductive structure 410, and the overlap area between the first sub-electrode 610 and the conductive structure 410 can be improved better, thereby the resistance of the display panel 10 can be reduced better and the working stability of the display panel 10 can be improved.

[0079] In some embodiments of the present application, the substrate 100 can include, for example, a substrate 110 and a driving circuit 150 disposed on the substrate 110. Optionally, the substrate 100 includes a first insulating layer 120, a second insulating layer 130, and a third insulating layer 140 which are stacked. Illustratively, the driving circuit 150 can include a transistor 151, a storage capacitor 152, and a driving signal line for connecting various devices, etc. The transistor 151 includes a semiconductor, a gate 151a, and a source / drain 151b. The storage capacitor 152 includes a first plate 152a and a second plate 152b.

[0080] As an example, the gate 151a and the first plate 152a can be located on a side of the first insulating layer 120 facing the substrate 110, the second plate 152b can be located between the first insulating layer 120 and the second insulating layer 130, and the source / drain 151b can be located between the second insulating layer 130 and the third insulating layer 140.

[0081] Optionally, the display panel 10 can further include a pixel definition layer 300 disposed on a side of the substrate 100, the pixel definition layer 300 can include a pixel defining portion 310 and a pixel opening 320 enclosed by the pixel defining portion 310, and the light emitting layer 500 can be partially located in the pixel opening 320. The pixel definition layer 300 can be used to participate in dividing the sub-pixels of the display panel 10.

[0082] Optionally, the isolation structure 400 and the pixel definition layer 300 can be arranged in various relative positions. For example, as shown in FIG. 4A, the isolation structure 400 can be arranged on the side of the pixel definition portion 310 away from the substrate 100. Alternatively, as shown in FIG. 4B, the pixel definition portion 310 can be provided with a receiving opening, and at least part of the isolation structure 400 can be arranged in the receiving opening, so as to reduce the thickness of the display panel 10. Figure 2

[0083] In some optional embodiments, the display panel 10 can further include a second electrode layer 200 arranged between the substrate 100 and the light-emitting layer 500, and the second electrode layer 200 can include a second electrode 210 arranged in the pixel opening 320.

[0084] Optionally, the light-emitting color of the first light-emitting unit 510 can be different from the light-emitting color of the second light-emitting unit 520, so as to facilitate color light-emitting display of the display panel 10. Optionally, the light-emitting layer 500 can further include a third light-emitting unit 530 arranged apart from the first light-emitting unit 510 and the second light-emitting unit 520, and the first electrode layer 600 can further include a third sub-electrode 630 overlapped with the conductive structure 410 and arranged on the side of the third light-emitting unit 530 away from the substrate 100, so that the adjacent first sub-electrode 610, second sub-electrode 620 and third sub-electrode 630 can be electrically connected through the conductive structure 410. The light-emitting color of the first light-emitting unit 510, the second light-emitting unit 520 and the third light-emitting unit 530 can be different, so as to further facilitate color display of the display panel 10. For example, the first light-emitting unit 510 can be used for emitting red light, the second light-emitting unit 520 can be used for emitting blue light, and the third light-emitting unit 530 can be used for emitting green light.

[0085] Optionally, the third light-emitting unit 530 has a third thickness, the third thickness is smaller than the first thickness, and the third thickness is greater than the second thickness.

[0086] Optionally, the third thickness can be the average thickness of the third light-emitting unit 530 at the overlapped position with the conductive structure 410, or the third thickness can be the average thickness of the third light-emitting unit 530, or the third thickness can be the maximum thickness of the third light-emitting unit 530.

[0087] Optionally, the part of the first light-emitting unit 510 having the maximum thickness, the part of the second light-emitting unit 520 having the maximum thickness, and the part of the third light-emitting unit 530 having the maximum thickness can all be located in the corresponding pixel opening 320.

[0088] ​Optionally, the first light emitting unit 510, the second light emitting unit 520 and the third light emitting unit 530 can each include a hole injection layer (HIL), a hole transport layer (HTL), a light emitting structure, an electron injection layer (EIL) and an electron transport layer (ETL) stacked together.

[0089] In these optional embodiments, the first electrode layer 600 and the second electrode layer 200 can serve as pixel electrode layers of the display panel 10, one of the first electrode layer 600 and the second electrode layer 200 can serve as an anode layer, and the other can serve as a cathode layer to drive the light emitting layer 500 to emit light. The embodiments of the present application take the second electrode layer 200 as the anode layer of the display panel 10, and the first electrode layer 600 as the cathode layer of the display panel 10, i.e., the second electrode 210 as the anode of the display panel 10, and the first sub-electrode 610, the second sub-electrode 620 and the third sub-electrode 630 as the cathode of the display panel 10, for example.

[0090] In some optional embodiments, the overlap width between the third light emitting unit 530 and the conductive structure 410 is smaller than the overlap width between the second light emitting unit 520 and the conductive structure 410, and / or the overlap width between the third light emitting unit 530 and the conductive structure 410 is larger than the overlap width between the first light emitting unit 510 and the conductive structure 410.

[0091] In this optional embodiment, by setting the overlap width between the third light emitting unit 530 and the conductive structure 410 to be smaller than the overlap width between the second light emitting unit 520 and the conductive structure 410, the third light emitting unit 530 with a moderate thickness is less likely to cover the conductive structure 410 excessively compared with the second light emitting unit 520 with a smaller thickness, so that the third light emitting unit 530 with a moderate thickness is less likely to cause excessive shielding effect on the overlap between the third sub-electrode 630 and the conductive structure 410, and the overlap area between the third sub-electrode 630 and the conductive structure 410 can be improved better, thereby the resistance of the display panel 10 can be reduced better and the working stability of the display panel 10 can be improved.

[0092] By setting the overlap width between the third type of light emitting unit 530 and the conductive structure 410 to be greater than the overlap width between the first type of light emitting unit 510 and the conductive structure 410, the first type of light emitting unit 510 with a larger thickness can further not easily cover the conductive structure 410 too much compared to the third type of light emitting unit 530 with a more moderate thickness, so that the first type of light emitting unit 510 with a larger thickness can not easily cause too much shielding effect on the overlap between the first sub-electrode 610 and the conductive structure 410, and can better improve the overlap area of the first sub-electrode 610 and the conductive structure 410.

[0093] Optionally, the isolation structure 400 encloses the isolation opening 400a, and the isolation opening 400a includes a first opening 400aa and a second opening 400ab. The first type of light emitting unit 510 is arranged corresponding to the first opening 400aa, and the second type of light emitting unit 520 is arranged corresponding to the second opening 400ab. Optionally, the isolation opening 400a can also include a third opening 400ac, and the third type of light emitting unit 530 can be arranged corresponding to the third opening 400ac, so that the isolation structure 400 can also be used to participate in dividing the sub-pixels of the display panel 10.

[0094] The isolation opening 400a can be in communication with the pixel opening 320. The first type of light emitting unit 510 arranged corresponding to the first opening 400aa can mean that the first type of light emitting unit 510 can be at least partially located in the first opening 400aa. The second type of light emitting unit 520 arranged corresponding to the second opening 400ab can mean that the first type of light emitting unit 510 can be at least partially located in the first opening 400aa. The third type of light emitting unit 530 arranged corresponding to the third opening 400ac can mean that the third type of light emitting unit 530 can be at least partially located in the third opening 400ac.

[0095] Specifically, the orthographic projection of the isolation structure 400 on the substrate 100 can be arranged around the orthographic projections of the first type of light emitting unit 510, the second type of light emitting unit 520, and the third type of light emitting unit 530 on the substrate 100, so that the first sub-electrode 610 above the first type of light emitting unit 510 can have a larger overlap area with the conductive structure 410 around the first opening 400aa, the second sub-electrode 620 above the second type of light emitting unit 520 can have a larger overlap area with the conductive structure 410 around the second opening 400ab, and the third sub-electrode 630 above the third type of light emitting unit 530 can have a larger overlap area with the conductive structure 410 around the third opening 400ac, thereby better reducing the resistance of the display panel 10.

[0096] As Figure 2As shown, in some optional embodiments, the isolation structure 400 includes a second isolation portion 420 located on the side of the conductive structure 410 away from the substrate 100, the second isolation portion 420 is protruded from the conductive structure 410 towards the isolation opening 400a.

[0097] Optionally, the material of the second isolation portion 420 can include titanium.

[0098] By protruding the second isolation portion 420 from the conductive structure 410 towards the isolation opening 400a, when evaporating the light-emitting layer 500 and the first electrode layer 600 of the display panel 10, the second isolation portion 420 can shield at least part of the material used to prepare the light-emitting layer 500 and the first electrode layer 600, so as to isolate the light-emitting layer 500 and the first electrode layer 600 between adjacent sub-pixels, and facilitate the formation of the first type of light-emitting unit 510, the second type of light-emitting unit 520 and the third type of light-emitting unit 530 arranged at intervals, and the first sub-electrode 610, the second sub-electrode 620 and the third sub-electrode 630 arranged at intervals, so that when evaporating the light-emitting layer 500 and the first electrode layer 600 of the display panel 10, a mask plate with high precision is not required, for example, a fine metal mask (FMM) is not required when evaporating the material of the light-emitting layer 500 and the first electrode layer 600, thereby reducing the production cost of the display panel 10.

[0099] In some embodiments of the present application, the light-emitting layer 500 can have certain conductive properties, that is, the light-emitting layer 500 can transmit a certain amount of current.

[0100] Optionally, when the light-emitting layer 500 is between the first electrode layer 600 and the conductive structure 410, the light-emitting layer 500 in contact with the conductive structure 410 and the first electrode layer 600 can also be used to conduct current, that is, the part of the first electrode layer 600 in contact with the light-emitting layer 500 and the conductive structure 410 can be electrically connected through the light-emitting layer 500. Among them, the thickness of the light-emitting layer 500 easily affects the impedance of the light-emitting layer 500 itself, for example, the thicker the thickness of the light-emitting layer 500, the higher the impedance of the light-emitting layer 500 itself.

[0101] Specifically, when the thicker first light emitting unit 510 is located between the first sub-electrode 610 and the conductive structure 410, the current between the first sub-electrode 610 and the conductive structure 410 has a large impedance when flowing to the first light emitting unit 510. Therefore, only the part of the first sub-electrode 610 in direct contact with the conductive structure 410 can achieve better electrical connection with the conductive structure 410, and the part of the first sub-electrode 610 located above the first light emitting unit 510 cannot achieve better electrical connection with the conductive structure 410. Therefore, when there are too many first light emitting units 510 between the first sub-electrode 610 and the conductive structure 410, that is, the overlap width between the first light emitting unit 510 and the conductive structure 410 is too large, the effective electrical connection area between the first sub-electrode 610 and the conductive structure 410 is small, which is not conducive to reducing the resistance of the display panel 10.

[0102] When the thinner second light emitting unit 520 is located between the second sub-electrode 620 and the conductive structure 410, the current between the second sub-electrode 620 and the conductive structure 410 has a small impedance when flowing to the second light emitting unit 520. Therefore, only the part of the second sub-electrode 620 above the second light emitting unit 520 and the part of the second sub-electrode 620 in direct contact with the conductive structure 410 can achieve better electrical connection with the conductive structure 410. Therefore, when there are certain second light emitting units 520 between the second sub-electrode 620 and the conductive structure 410, that is, the overlap width between the second light emitting unit 520 and the conductive structure 410 is large, the effective electrical connection area between the second sub-electrode 620 and the conductive structure 410 is not easy to be too small, so that the display panel 10 can have a more appropriate resistance. Similarly, when the third light emitting unit 530 with a moderate thickness compared to the second light emitting unit 520 and the first light emitting unit 510 is overlapped with the conductive structure 410, the third light emitting unit 530 has a moderate influence on the electrical connection between the third sub-electrode 630 and the conductive structure 410.

[0103] Therefore, the overlap relationship between each position on the light emitting layer 500 and the conductive structure 410 can be further refined according to the thicknesses of the first light emitting unit 510, the second light emitting unit 520 and the third light emitting unit 530, to better improve the overlap effect between the first electrode layer 600 and the conductive structure 410 and improve the working stability of the display panel 10.

[0104] In some embodiments of the present application, the optional overlap between one and another can refer to the mutual contact between one and another. The overlap width between one and another can refer to the width of the surface of one and another in mutual contact, or the overlap width between one and another can refer to the width of the surface of one and another in mutual contact in the orthographic projection on the substrate 100. Wherein the greater the overlap width means the greater the surface area of one and another in mutual contact.

[0105] Wherein the width of the surface of one and another in mutual contact can refer to the width of the surface of one and another in mutual contact in a cross-sectional view, for example, can refer to the width of the surface of one and another in mutual contact in a cross-sectional view in a direction perpendicular to the thickness direction X of the display panel 10.

[0106] Specifically, when at least part of the surface between one and another is in mutual contact, it can be considered that the overlap width between one and another is greater than zero, and when one and another are spaced apart, it can be considered that the overlap width between one and another is equal to zero.

[0107] As shown in some optional embodiments, Figure 2 The overlap width between the first type of light emitting unit 510 and the conductive structure 410 is greater than zero, the surface of the first type of light emitting unit 510 that overlaps with the conductive structure 410 is the first overlap surface 511, the width of the orthographic projection of the first overlap surface 511 on the substrate 100 is the first width W1, the overlap width between the second type of light emitting unit 520 and the conductive structure 410 is greater than zero, the surface of the second type of light emitting unit 520 that overlaps with the conductive structure 410 is the second overlap surface 521, the width of the orthographic projection of the second overlap surface 521 on the substrate 100 is the second width W2, and the first width W1 is less than the second width W2.

[0108] Optionally, the orthographic projection of the first overlap surface 511 on the substrate 100 is annular, and / or the orthographic projection of the second overlap surface 521 on the substrate 100 is annular.

[0109] Optionally, the orthographic projection of the first overlap surface 511 on the substrate 100 is annular, which can mean that the first type of light emitting unit 510 overlaps with the conductive structure 410 around the first opening 400aa. Wherein the first width W1 can refer to the minimum distance between the orthographic projection on the substrate 100 of the edge of the first overlap surface 511 close to the pixel opening 320 and the orthographic projection on the substrate 100 of the edge of the first overlap surface 511 away from the pixel opening 320.

[0110] Optionally, the normal projection of the edge of the first lapping surface 511 on the substrate 100 close to the side of the pixel opening 320 can coincide with the normal projection of the conductive structure 410 on the substrate 100 close to the edge of the first opening 400aa. The normal projection of the edge of the first lapping surface 511 on the substrate 100 away from the side of the pixel opening 320 can be the normal projection of the edge of the first light emitting unit 510 on the substrate 100.

[0111] Optionally, the normal projection of the second lapping surface 521 on the substrate 100 is annular, which can mean that the second light emitting unit 520 and the conductive structure 410 around the second opening 400ab are lapped. The second width W2 can mean the minimum distance between the normal projection of the edge of the second lapping surface 521 on the substrate 100 close to the side of the pixel opening 320 and the normal projection of the edge of the second lapping surface 521 on the substrate 100 away from the side of the pixel opening 320.

[0112] Optionally, the normal projection of the edge of the second lapping surface 521 on the substrate 100 close to the side of the pixel opening 320 can coincide with the normal projection of the conductive structure 410 on the substrate 100 close to the edge of the second opening 400ab. The normal projection of the edge of the second lapping surface 521 on the substrate 100 away from the side of the pixel opening 320 can be the normal projection of the edge of the second light emitting unit 520 on the substrate 100.

[0113] In these optional embodiments, by setting the first width W1 to be less than the second width W2, the lapping width between the first light emitting unit 510 and the conductive structure 410 can be facilitated to be less than the lapping width between the second light emitting unit 520 and the conductive structure 410, so that compared with the second light emitting unit 520 with a smaller thickness, the first light emitting unit 510 with a larger thickness is less likely to cover the conductive structure 410 around the first opening 400aa, so that the first light emitting unit 510 with a larger thickness is less likely to cause excessive shielding effect on the lapping between the first sub-electrode 610 and the conductive structure 410 around the first opening 400aa, which can better improve the effective electrical connection area between the first sub-electrode 610 and the conductive structure 410, thereby better reducing the resistance of the display panel 10 and improving the working stability of the display panel 10.

[0114] Please continue to refer to Figure 2 In some optional embodiments, the lapping width between the third light emitting unit 530 and the conductive structure 410 is greater than zero, the surface of the third light emitting unit 530 lapped with the conductive structure 410 is the fifth lapping surface 531, the width of the normal projection of the fifth lapping surface 531 on the substrate 100 is the fifth width W5, the fifth width W5 is less than the second width W2, and the fifth width W5 is greater than the second width W2.

[0115] Optionally, the fifth overlap surface 531 has a projection on the substrate 100 in a ring shape.

[0116] Optionally, the fifth overlap surface 531 has a projection on the substrate 100 in a ring shape, which can mean that the third type of light emitting unit 530 and the conductive structure 410 around the third opening 400ac are all overlapped. The fifth width W5 can mean the minimum distance between the projection on the substrate 100 of the edge of the fifth overlap surface 531 close to the pixel opening 320 and the projection on the substrate 100 of the edge of the fifth overlap surface 531 away from the pixel opening 320.

[0117] Optionally, the projection on the substrate 100 of the edge of the fifth overlap surface 531 close to the pixel opening 320 can coincide with the projection on the substrate 100 of the edge of the conductive structure 410 close to the third opening 400ac. The projection on the substrate 100 of the edge of the fifth overlap surface 531 away from the pixel opening 320 can be the projection on the substrate 100 of the edge of the third type of light emitting unit 530.

[0118] In these optional embodiments, by setting the fifth width W5 to be less than the second width W2 and setting the fifth width W5 to be greater than the second width W2, the overlap width between the third type of light emitting unit 530 and the conductive structure 410 can be less than the overlap width between the second type of light emitting unit 520 and the conductive structure 410, and the overlap width between the third type of light emitting unit 530 and the conductive structure 410 can be greater than the overlap width between the first type of light emitting unit 510 and the conductive structure 410, so that compared with the second type of light emitting unit 520 with a smaller thickness, the third type of light emitting unit 530 with a moderate thickness is less likely to cover the conductive structure 410 around the third opening 400ac too much, so that the third type of light emitting unit 530 with a moderate thickness is less likely to cause excessive shielding effect on the overlap between the third sub-electrode 630 and the conductive structure 410 around the third opening 400ac, which can better improve the effective electrical connection area between the third sub-electrode 630 and the conductive structure 410, thereby better reducing the resistance of the display panel 10 and improving the working stability of the display panel 10.

[0119] Also, compared with the third type of light emitting unit 530 with a moderate thickness, the first type of light emitting unit 510 with a larger thickness can further be less likely to cover the conductive structure 410 too much, so that the first type of light emitting unit 510 with a larger thickness is less likely to cause excessive shielding effect on the overlap between the first sub-electrode 610 and the conductive structure 410, which can better improve the overlap area between the first sub-electrode 610 and the conductive structure 410.

[0120] Figure 3 is a partial cross-sectional view of a display panel 10 provided by another embodiment of the present application.

[0121] As shown in FIG. 13, in some optional embodiments, the overlap width between the first light emitting units 510 and the conductive structures 410 can be equal to zero, the overlap width between the second light emitting units 520 and the conductive structures 410 can be greater than zero, and the first light emitting units 510 are spaced apart from the conductive structures 410. Figure 3

[0122] Optionally, the overlap width between the third light emitting units 530 and the conductive structures 410 can also be greater than zero, and the fifth width W5 can be greater than the second width W2.

[0123] In these optional embodiments, by spacing the first light emitting units 510 with relatively thick thicknesses away from the conductive structures 410, the surfaces of the conductive structures 410 around the first openings 400aa can be better exposed after the first light emitting units 510 in the first openings 400aa are prepared, so that the material of the first sub-electrodes 610 can better fall on the surfaces of the conductive structures 410 when the first sub-electrodes 610 are prepared in the first openings 400aa, and the first sub-electrodes 610 can be less affected by the first light emitting units 510 with relatively thick thicknesses and can be better connected to the surfaces of the conductive structures 410 with larger areas, which can better improve the connection area of the first sub-electrodes 610 and the conductive structures 410, thereby better reducing the resistance of the display panel 10 and improving the working stability of the display panel 10.

[0124] Figure 4 FIG. 14 is a partial cross-sectional view of a display panel 10 according to another embodiment of the present application.

[0125] As shown in FIG. 13, in some optional embodiments, the overlap width between the first light emitting units 510 and the conductive structures 410 can be equal to zero, the overlap width between the second light emitting units 520 and the conductive structures 410 can be greater than zero, and the first light emitting units 510 are spaced apart from the conductive structures 410. Figure 4

[0126] Optionally, when the overlap width between the third light emitting units 530 and the conductive structures 410 is equal to zero, the overlap width between the first light emitting units 510 and the conductive structures 410 can also be equal to zero.

[0127] Optionally, the minimum distance between the third light emitting units 530 and the conductive structures 410 can be less than or equal to the minimum distance between the first light emitting units 510 and the conductive structures 410.

[0128] ​​In these optional embodiments, by setting the third light emitting unit 530 of the third type with a relatively moderate thickness to be spaced apart from the conductive structure 410, after the third light emitting unit 530 of the third type in the third opening 400ac is prepared, the surface of the conductive structure 410 around the third opening 400ac can be better exposed, so that when the third sub-electrode 630 is prepared in the third opening 400ac, the material of the third sub-electrode 630 can better fall on the surface of the conductive structure 410, so that the third sub-electrode 630 can be less affected by the shielding of the third light emitting unit 530 of the third type with a relatively moderate thickness and be connected to the surface of the conductive structure 410 with a larger area, which can better improve the connection area of the third sub-electrode 630 and the conductive structure 410, thereby better reducing the resistance of the display panel 10 and improving the working stability of the display panel 10.

[0129] Figure 5 is a partial cross-sectional view of a display panel 10 provided in another embodiment of the present application.

[0130] As shown in Figure 5 , in some optional embodiments, the connection width between the first sub-electrode 610 and the conductive structure 410 is greater than the connection width between the second sub-electrode 620 and the conductive structure 410.

[0131] Optionally, after the relative position relationship and the connection width between the light emitting layer 500 and the conductive structure 410 in the at least partial embodiments described above are set, the connection width between the first sub-electrode 610 and the conductive structure 410 can be greater than the connection width between the second sub-electrode 620 and the conductive structure 410. For example, after the relative position relationship and the connection width between the light emitting layer 500 and the conductive structure 410 in the at least partial embodiments described above are set, the conductive structure 410 around the first opening 400aa can have a larger surface area to facilitate connection with the first sub-electrode 610, thereby better facilitating the connection width between the first sub-electrode 610 and the conductive structure 410 to be greater than the connection width between the second sub-electrode 620 and the conductive structure 410.

[0132] Optionally, the overlap width between the first sub-electrode 610 and the conductive structure 410 is greater than zero, a surface of the first sub-electrode 610 that overlaps with the conductive structure 410 is a third overlap surface 611, a width of a projection of the third overlap surface 611 on the substrate 100 is a third width W3, the overlap width between the second sub-electrode 620 and the conductive structure 410 is greater than zero, a surface of the second sub-electrode 620 that overlaps with the conductive structure 410 is a fourth overlap surface 621, a width of a projection of the fourth overlap surface 621 on the substrate 100 is a fourth width W4, and the third width W3 is greater than the fourth width W4. By setting the third width W3 to be greater than the fourth width W4, the overlap width between the first sub-electrode 610 and the conductive structure 410 can be made greater than the overlap width between the second sub-electrode 620 and the conductive structure 410.

[0133] Optionally, the projection of the third overlap surface 611 on the substrate 100 is annular, and / or the projection of the fourth overlap surface 621 on the substrate 100 is annular.

[0134] Optionally, the projection of the third overlap surface 611 on the substrate 100 being annular can mean that the first sub-electrode 610 overlaps with the conductive structure 410 around the first opening 400aa. The third width W3 can mean the minimum distance between the projection on the substrate 100 of an edge of the third overlap surface 611 close to the pixel opening 320 and the projection on the substrate 100 of an edge of the third overlap surface 611 away from the pixel opening 320.

[0135] Optionally, the projection of the fourth overlap surface 621 on the substrate 100 being annular can mean that the second sub-electrode 620 overlaps with the conductive structure 410 around the second opening 400ab. The fourth width W4 can mean the minimum distance between the projection on the substrate 100 of an edge of the fourth overlap surface 621 close to the pixel opening 320 and the projection on the substrate 100 of an edge of the fourth overlap surface 621 away from the pixel opening 320.

[0136] In these optional embodiments, by setting the overlap width between the first sub-electrode 610 and the conductive structure 410 to be greater than the overlap width between the second sub-electrode 620 and the conductive structure 410, the first sub-electrode 610 can be less affected by the first type of light emitting unit 510 having a relatively large thickness and can have a better direct contact area with the conductive structure 410, so that the first sub-electrode 610 can have a better effective electrical connection area with the conductive structure 410 and be less affected by the first type of light emitting unit 510 having a relatively large impedance.

[0137] Please continue to refer to Figure 5In some optional embodiments, the overlap width between the third sub-electrode 630 and the conductive structure 410 is less than or equal to the overlap width between the first sub-electrode 610 and the conductive structure 410, and / or the overlap width between the third sub-electrode 630 and the conductive structure 410 is greater than the overlap width between the second sub-electrode 620 and the conductive structure 410.

[0138] Optionally, after the relative positional relationship and the overlap width between the light-emitting layer 500 and the conductive structure 410 in the at least partial embodiments described above are set, it is easier to achieve that the overlap width between the third sub-electrode 630 and the conductive structure 410 is less than or equal to the overlap width between the first sub-electrode 610 and the conductive structure 410, and it is easier to achieve that the overlap width between the third sub-electrode 630 and the conductive structure 410 is greater than the overlap width between the second sub-electrode 620 and the conductive structure 410. For example, after the relative positional relationship and the overlap width between the light-emitting layer 500 and the conductive structure 410 in the at least partial embodiments described above are set, the conductive structure 410 around the third opening 400ac can have a moderate surface area to facilitate the overlap with the third sub-electrode 630, so that it is easier to achieve that the overlap width between the third sub-electrode 630 and the conductive structure 410 is less than or equal to the overlap width between the first sub-electrode 610 and the conductive structure 410, and it is easier to achieve that the overlap width between the third sub-electrode 630 and the conductive structure 410 is greater than the overlap width between the second sub-electrode 620 and the conductive structure 410.

[0139] Optionally, as shown in FIG. 6, when the first type of light-emitting unit 510 and the third type of light-emitting unit 530 are both spaced apart from the conductive structure 410, the overlap width between the third sub-electrode 630 and the conductive structure 410 can be equal to the overlap width between the first sub-electrode 610 and the conductive structure 410. Figure 5

[0140] Optionally, the overlap width between the third sub-electrode 630 and the conductive structure 410 is greater than zero, the surface of the third sub-electrode 630 that overlaps with the conductive structure 410 is a sixth overlap surface 631, the width of the orthogonal projection of the sixth overlap surface 631 on the substrate 100 is a sixth width W6, the sixth width W6 is greater than the fourth width W4, and the sixth width W6 is less than or equal to the third width W3. By setting the sixth width W6 to be greater than the fourth width W4 and the sixth width W6 to be less than or equal to the third width W3, the overlap width between the third sub-electrode 630 and the conductive structure 410 can be less than or equal to the overlap width between the first sub-electrode 610 and the conductive structure 410, and the overlap width between the third sub-electrode 630 and the conductive structure 410 can be greater than the overlap width between the second sub-electrode 620 and the conductive structure 410.

[0141] Optionally, the orthogonal projection of the sixth overlap surface 631 on the substrate 100 is annular.​

[0142] Optionally, the orthographic projection of the sixth overlapping surface 631 on the substrate 100 is annular, which may refer to the fact that the third sub-electrode 630 and the conductive structure 410 around the third opening 400ac are both overlapping. The sixth width W6 may refer to the minimum distance between the orthographic projection of the edge of the sixth overlapping surface 631 near the pixel opening 320 on the substrate 100 and the orthographic projection of the edge of the sixth overlapping surface 631 away from the pixel opening 320 on the substrate 100.

[0143] In these optional embodiments, by setting the overlap width between the third sub-electrode 630 and the conductive structure 410 to be greater than the overlap width between the second sub-electrode 620 and the conductive structure 410, the third sub-electrode 630 is less likely to be blocked by the third type of light-emitting unit 530 with a relatively moderate thickness and can have a better direct contact area with the conductive structure 410. This allows the third sub-electrode 630 to have a better effective electrical connection area with the conductive structure 410, which is less likely to be affected by the third type of light-emitting unit 530 with a certain impedance.

[0144] Furthermore, by setting the overlap width between the third sub-electrode 630 and the conductive structure 410 to be less than or equal to the overlap width between the first sub-electrode 610 and the conductive structure 410, the first sub-electrode 610 is less susceptible to being blocked by the first type of light-emitting unit 510, which has a thicker thickness than the third type of covering unit. This further enables the first sub-electrode 610 to have a better direct contact area with the conductive structure 410, and further enables the first sub-electrode 610 to have a better effective electrical connection area with the conductive structure 410, which is less susceptible to being affected by the first type of light-emitting unit 510 with a larger impedance.

[0145] like Figure 5 As shown, in some optional embodiments, the conductive structure 410 includes a conductive portion 412 and a first isolation portion 411 located on the side of the conductive portion 412 away from the substrate 100. A second isolation portion 420 is disposed protruding from the first isolation portion 411 toward the isolation opening 400a. The conductive portion 412 is disposed protruding from the first isolation portion 411 toward the isolation opening 400a. The first sub-electrode 610 and the second sub-electrode 620 are both connected to the conductive portion 412.

[0146] Optionally, the third sub-electrode 630 is also connected to the conductive part 412.

[0147] Optionally, the material of the conductive part 412 includes molybdenum, and / or the material of the first insulating part 411 includes aluminum.

[0148] In these optional embodiments, by providing the conductive portion 412 to protrude from the first isolation portion 411 toward the isolation opening 400a, the conductive portion 412 can have a larger size to facilitate the overlap between the first electrode layer 600 and the isolation structure 400, thereby increasing the overlap area between the first electrode layer 600 and the isolation structure 400 and thus improving the operational stability of the display panel 10. Furthermore, by providing the conductive portion 412 as a material including molybdenum, the conductive portion 412 has good oxidation resistance, ensuring a good electrical connection between the first electrode layer 600 and the conductive portion 412 when they overlap, thereby further improving the operational stability of the display panel 10.

[0149] In some alternative embodiments, the first sub-electrode 610 overlaps with the first isolation portion 411, and / or the second sub-electrode 620 overlaps with the first isolation portion 411.

[0150] Optionally, the third sub-electrode 630 may also be connected to the first isolation section 411.

[0151] In these optional embodiments, by setting the first sub-electrode 610, the second sub-electrode 620, and the third sub-electrode 630 to overlap with the first isolation portion 411, the overlap area between the first sub-electrode 610, the second sub-electrode 620, and the third sub-electrode 630 and the conductive structure 410 can be further increased, so that the first sub-electrode 610, the second sub-electrode 620, and the third sub-electrode 630 of adjacent sub-pixels can be electrically connected through the first isolation portion 411, thereby further reducing the resistance of the display panel 10.

[0152] Among them, compared with the conductive part 412 made of molybdenum, the first insulating part 411 made of aluminum is more easily oxidized. Therefore, the electrical connection between the first electrode layer 600 and the conductive part 412 is better than the electrical connection between the first electrode layer 600 and the first insulating part 411.

[0153] like Figure 5 As shown, in some optional embodiments, both the first type of light-emitting unit 510 and the second type of light-emitting unit 520 are spaced apart from the first isolation portion 411, and the overlap width between the first type of light-emitting unit 510 and the conductive portion 412 is smaller than the overlap width between the second type of light-emitting unit 520 and the conductive portion 412.

[0154] Optionally, the first light emitting units 510, the second light emitting units 520 and the third light emitting units 530 are spaced apart from the first isolation portion 411, the overlap width between the third light emitting units 530 and the conductive portion 412 is smaller than the overlap width between the second light emitting units 520 and the conductive portion 412, and / or the overlap width between the third light emitting units 530 and the conductive portion 412 is larger than the overlap width between the first light emitting units 510 and the conductive portion 412.

[0155] In these optional embodiments, by spacing the first light emitting units 510, the second light emitting units 520 and the third light emitting units 530 apart from the first isolation portion 411, the overlap area between the light emitting layer 500 and the conductive structure 410 is not prone to be too large, i.e., the light emitting layer 500 covering the conductive structure 410 is not prone to be too large, thereby better facilitating the overlap between the first electrode layer 600 and the conductive structure 410 and better reducing the resistance of the display panel 10.

[0156] In the foregoing embodiments, the "overlap width between the first light emitting units 510 and the conductive structure 410 is smaller than the overlap width between the second light emitting units 520 and the conductive structure 410" can refer to "the overlap width between the first light emitting units 510 and the conductive portion 412 is smaller than the overlap width between the second light emitting units 520 and the conductive portion 412"; and the "overlap width between the third light emitting units 530 and the conductive structure 410 is smaller than the overlap width between the second light emitting units 520 and the conductive structure 410, and / or the overlap width between the third light emitting units 530 and the conductive structure 410 is larger than the overlap width between the first light emitting units 510 and the conductive structure 410" can refer to "the overlap width between the third light emitting units 530 and the conductive portion 412 is smaller than the overlap width between the second light emitting units 520 and the conductive portion 412, and / or the overlap width between the third light emitting units 530 and the conductive portion 412 is larger than the overlap width between the first light emitting units 510 and the conductive portion 412".

[0157] In some embodiments of the present application, the relative position and the overlap relationship between the light emitting layer 500 and the conductive structure 410 in any of the foregoing embodiments can be achieved by adjusting the evaporation angle of the light emitting layer 500 during the preparation of the display panel 10.

[0158] In some other embodiments of the present application, the relative position and the overlap relationship between the light emitting layer 500 and the conductive structure 410 in any of the foregoing embodiments can also be achieved by adjusting the morphology of the isolation structure 400 to adjust the shielding and blocking effect of the isolation structure 400 on the material of the light emitting layer 500.

[0159] Specifically, when the protruding length of the second isolation portion 420 in the isolation structure 400 toward the side of the isolation opening 400a relative to the first isolation portion 411 is longer, the shielding effect of the second isolation portion 420 on the material of the light-emitting layer 500 is greater during the preparation of the display panel 10, so that less material of the light-emitting layer 500 can fall below the second isolation portion 420, thereby better reducing the overlap width and overlap area between the light-emitting layer 500 and the conductive structure 410. When the protruding length of the second isolation portion 420 in the isolation structure 400 toward the side of the isolation opening 400a relative to the first isolation portion 411 is shorter, the shielding effect of the second isolation portion 420 on the material of the light-emitting layer 500 is smaller during the preparation of the display panel 10, so that more material of the light-emitting layer 500 can fall below the second isolation portion 420, thereby better enabling the light-emitting layer 500 and the conductive structure 410 to have a better overlap width and overlap area.

[0160] The protruding length of the second isolation portion 420 toward the side of the isolation opening 400a relative to the first isolation portion 411 can refer to the minimum distance between the orthographic projection of the edge of the second isolation portion 420 toward the side of the isolation opening 400a on the substrate 100 and the orthographic projection of the surface of the first isolation portion 411 away from the substrate 100 toward the side of the isolation opening 400a on the substrate 100.

[0161] Figure 6 is a partial cross-sectional view of a display panel 10 provided by another embodiment of the present application, Figure 7 is a partial enlarged cross-sectional view of a display panel 10 provided by an embodiment of the present application, Figure 8 is a partial enlarged cross-sectional view of a display panel 10 provided by another embodiment of the present application.

[0162] As shown in Figure 6 to Figure 8 In some optional embodiments, the protruding length of the second isolation portion 420 toward the side of the first opening 400aa relative to the first isolation portion 411 is greater than the protruding length of the second isolation portion 420 toward the side of the second opening 400ab relative to the first isolation portion 411.

[0163] In the optional embodiment, by reasonably setting the protruding length of the second isolation portion 420 around the first opening 400aa and the protruding length of the second isolation portion 420 around the second opening 400ab, the protruding length of the second isolation portion 420 around the first opening 400aa is longer than that of the first isolation portion 411 towards the side of the first opening 400aa, so that in the preparation process of the display panel 10, the second isolation portion 420 around the first opening 400aa has a greater shielding effect on the material of the light-emitting layer 500, so as to better achieve the relative position relationship and the lap relationship between the first light-emitting unit 510 and the conductive structure 410 in the foregoing embodiment, so that the first light-emitting unit 510 with a relatively thick thickness is less likely to be excessively shielded and covered on the surface of the conductive portion 412, thereby better improving the lap width and lap area between the first sub-electrode 610 above the first light-emitting unit 510 with a relatively thick thickness and the conductive portion 412, so that the display panel 10 can have a smaller resistance, thereby improving the working stability of the display panel 10.

[0164] Please continue to refer to Figure 6 In some optional embodiments, the protruding length of the second isolation portion 420 towards the side of the third opening 400ac relative to the first isolation portion 411 is greater than the protruding length of the second isolation portion 420 towards the side of the second opening 400ab relative to the first isolation portion 411, and / or the protruding length of the second isolation portion 420 towards the side of the third opening 400ac relative to the first isolation portion 411 is less than the protruding length of the second isolation portion 420 towards the side of the first opening 400aa relative to the first isolation portion 411.

[0165] In the optional embodiment, by reasonably setting the protruding length of the second isolation portion 420 around the first opening 400aa, the protruding length of the second isolation portion 420 around the second opening 400ab, and the protruding length of the second isolation portion 420 around the third opening 400ac, the protruding length of the second isolation portion 420 around the third opening 400ac relative to the first isolation portion 411 towards the side of the third opening 400ac is moderate, so that in the preparation process of the display panel 10, the second isolation portion 420 around the third opening 400ac has a moderate shielding effect on the material of the light-emitting layer 500, so as to better achieve the relative position relationship and the lap relationship between the third light-emitting unit 530 and the conductive structure 410 in the foregoing embodiment, so that the third light-emitting unit 530 with a moderate thickness is less likely to be excessively shielded and covered on the surface of the conductive portion 412, thereby better improving the lap width and lap area between the first sub-electrode 610 above the third light-emitting unit 530 with a moderate thickness and the conductive portion 412, so that the display panel 10 can have a smaller resistance, thereby improving the working stability of the display panel 10.

[0166] And, by setting the protruding length of the second isolation portion 420 relative to the first isolation portion 411 toward the side of the third opening 400ac to be smaller than the protruding length of the second isolation portion 420 relative to the first isolation portion 411 toward the side of the first opening 400aa, the shielding effect of the second isolation portion 420 on the material of the light-emitting layer 500 around the first opening 400aa can be further improved, so that the overlap width and overlap area between the first sub-electrode 610 above the first light-emitting unit 510 of the first type with a relatively thick thickness and the conductive portion 412 can be further improved, so that the display panel 10 can have a smaller resistance.

[0167] Based on the above-mentioned embodiments, by adjusting the morphology of the isolation structure 400 to adjust the shielding and blocking effect of the isolation structure 400 on the material of the light-emitting layer 500, similarly, when the morphology of the isolation structure 400 is adjusted, the shielding and blocking effect of the isolation structure 400 on the material of the first electrode layer 600 can also be adjusted.

[0168] Specifically, the longer the protruding length of the second isolation portion 420 relative to the first isolation portion 411 toward the side of the isolation opening 400a in the isolation structure 400, the greater the shielding effect of the second isolation portion 420 on the material of the first electrode layer 600 during the preparation of the display panel 10, so that the less the material of the first electrode layer 600 that can fall below the second isolation portion 420, thereby reducing the overlap area between the area of the first electrode layer 600 on the substrate 100 and the area of the conductive structure 410 on the substrate 100. When the protruding length of the second isolation portion 420 relative to the first isolation portion 411 toward the side of the isolation opening 400a in the isolation structure 400 is shorter, the smaller the shielding effect of the second isolation portion 420 on the material of the first electrode layer 600 during the preparation of the display panel 10, so that the more the material of the first electrode layer 600 that can fall below the second isolation portion 420, thereby increasing the overlap area between the area of the first electrode layer 600 on the substrate 100 and the area of the conductive structure 410 on the substrate 100.

[0169] In some optional embodiments of the present application, after the protruding length of the second isolation portion 420 around the first opening 400aa, the second opening 400ab and the third opening 400ac is adjusted in the above-mentioned embodiments, the evaporation formation range between the first sub-electrode 610 in the first opening 400aa, the second sub-electrode 620 in the second opening 400ab and the third sub-electrode 630 in the third opening 400ac and the conductive structure 410 will also be changed accordingly.

[0170] Please continue to refer to Figure 6In some alternative embodiments, after the adjustment of the protruding length of the second isolation portion 420 around the first opening 400aa, the second opening 400ab, and the third opening 400ac in the foregoing embodiments, the first sub-electrode 610 in the first opening 400aa, the second sub-electrode 620 in the second opening 400ab, and the third sub-electrode 630 in the third opening 400ac can still be in contact with the conductive portion 412 and the first isolation portion 411 of the conductive structure 410, so that after the adjustment of the protruding length of the second isolation portion 420 around the openings 400a, the first electrode layer 600 can still have a proper contact area and contact width with the conductive structure 410.

[0171] At this time, although the total contact width of the first sub-electrode 610 in the first opening 400aa, the total contact width of the second sub-electrode 620 in the second opening 400ab, and the total contact width of the third sub-electrode 630 in the third opening 400ac cannot be adjusted accurately, the contact width between the first sub-electrode 610 and the conductive portion 412 in the first opening 400aa, the contact width between the first sub-electrode 610 and the first isolation portion 411 in the first opening 400aa, the contact width between the second sub-electrode 620 and the conductive portion 412 in the second opening 400ab, the contact width between the second sub-electrode 620 and the first isolation portion 411 in the second opening 400ab, the contact width between the third sub-electrode 630 and the conductive portion 412 in the third opening 400ac, and the contact width between the third sub-electrode 630 and the first isolation portion 411 in the third opening 400ac can be adjusted accurately.

[0172] In the following alternative embodiments, the contact relationship between the first sub-electrode 610 in the first opening 400aa, the second sub-electrode 620 in the second opening 400ab, and the third sub-electrode 630 in the third opening 400ac and the conductive structure 410 will be described in detail.

[0173] Optionally, the contact width between the first sub-electrode 610 and the conductive portion 412 is greater than the contact width between the second sub-electrode 620 and the conductive portion 412, and / or the contact width between the first sub-electrode 610 and the first isolation portion 411 is less than the contact width between the second sub-electrode 620 and the first isolation portion 411.

[0174] Specifically, the overlap width between the first sub-electrode 610 and the conductive part 412 is greater than zero, the surface of the first sub-electrode 610 that overlaps with the conductive part 412 is a first sub-overlap surface 611a, the width of the orthographic projection of the first sub-overlap surface 611a on the substrate 100 is a first sub-width D1, the overlap width between the second sub-electrode 620 and the conductive part 412 is greater than zero, the surface of the second sub-electrode 620 that overlaps with the conductive part 412 is a second sub-overlap surface 621a, the width of the orthographic projection of the second sub-overlap surface 621a on the substrate 100 is a second sub-width D2, the first sub-width D1 is greater than the second sub-width D2, that is, it is convenient to realize that the overlap width between the first sub-electrode 610 and the conductive part 412 can be greater than the overlap width between the second sub-electrode 620 and the conductive part 412.

[0175] Optionally, the orthographic projection of the first sub-overlap surface 611a on the substrate 100 is annular, and / or the orthographic projection of the second sub-overlap surface 621a on the substrate 100 is annular.

[0176] Optionally, the orthographic projection of the first sub-overlap surface 611a on the substrate 100 is annular, which can mean that the first sub-electrode 610 overlaps with the conductive part 412 around the first opening 400aa. Among them, the first sub-width D1 can mean the minimum distance between the orthographic projection on the substrate 100 of the edge of the first sub-overlap surface 611a close to one side of the pixel opening 320 and the orthographic projection on the substrate 100 of the edge of the first sub-overlap surface 611a away from one side of the pixel opening 320.

[0189] In these optional embodiments, after adjusting the protruding length of the second isolation portion 420 around the periphery of the first opening 400aa, the second opening 400ab, and the third opening 400ac, the evaporation forming range between the first sub-electrode 610 in the first opening 400aa, the second sub-electrode 620 in the second opening 400ab, the third sub-electrode 630 in the third opening 400ac, and the conductive structure 410 will be changed accordingly. Specifically, when the second isolation portion 420 around the periphery of the first opening 400aa has a larger protruding length, the second isolation portion 420 around the periphery of the first opening 400aa can better shield the material of the light-emitting layer 500 and the material of the first electrode layer 600, so that the first light-emitting unit 510 with a larger thickness can cover and shield the conductive portion 412 less, thereby making the overlap width between the first sub-electrode 610 and the conductive portion 412 larger, for example, the overlap width between the first sub-electrode 610 and the conductive portion 412 is larger than the overlap width between the second sub-electrode 620 and the conductive portion 412, and the overlap width between the first sub-electrode 610 and the conductive portion 412 is larger than the overlap width between the third sub-electrode 630 and the conductive portion 412, thereby making the first sub-electrode 610 have a better overlap area with the conductive portion 412.

[0190] Although the overlap width between the first sub-electrode 610 and the first isolation portion 411 is smaller, for example, the overlap width between the first sub-electrode 610 and the first isolation portion 411 is smaller than the overlap width between the second sub-electrode 620 and the first isolation portion 411, and the overlap width between the first sub-electrode 610 and the first isolation portion 411 is smaller than the overlap width between the third sub-electrode 630 and the first isolation portion 411, due to the larger shielding effect of the second isolation portion 420 around the periphery of the first opening 400aa, the electrical connection area between the first sub-electrode 610 and the first isolation portion 411 is smaller, but since the electrical connection effect between the first sub-electrode 610 and the conductive portion 412 that is not easily oxidized is better than that between the first sub-electrode 610 and the first isolation portion 411 that is easily oxidized, after the aforementioned embodiments are set to improve the overlap width between the first sub-electrode 610 and the conductive portion 412, the electrical connection effect between the first sub-electrode 610 as a whole and the conductive structure 410 can be better, which can better reduce the resistance of the display panel 10 and improve the working stability of the display panel 10.

[0191] Similarly, when the second isolation portion 420 on the side of the third opening 400ac has a moderate protruding length, the second isolation portion 420 on the side of the first opening 400aa can better shield the material of the light-emitting layer 500 from the material of the first electrode layer 600, so that the third light-emitting unit 530 of the third type with a moderate thickness can less cover and shield the conductive portion 412, so that the lap width between the third sub-electrode 630 and the conductive portion 412 is larger, for example, the lap width between the third sub-electrode 630 and the conductive portion 412 is larger than the lap width between the second sub-electrode 620 and the conductive portion 412, and thus the third sub-electrode 630 can have a better lap area with the conductive portion 412.

[0192] Although the lap width between the third sub-electrode 630 and the first isolation portion 411 is small, for example, the lap width between the third sub-electrode 630 and the first isolation portion 411 is smaller than the lap width between the second sub-electrode 620 and the first isolation portion 411, due to the moderate shielding of the second isolation portion 420 on the side of the third opening 400ac, the electrical connection area between the third sub-electrode 630 and the first isolation portion 411 is small, but since the electrical connection effect between the third sub-electrode 630 and the conductive portion 412 that is not easily oxidized is better than that between the third sub-electrode 630 and the first isolation portion 411 that is easily oxidized, after the lap width between the third sub-electrode 630 and the conductive portion 412 is increased by the arrangement in the foregoing embodiment, the electrical connection effect between the third sub-electrode 630 as a whole and the conductive structure 410 can be better, which can better reduce the resistance of the display panel 10 and improve the working stability of the display panel 10.

By setting the overlap width between the first sub-electrodes 610 and the conductive structures 410 to be greater than the overlap width between the second sub-electrodes 620 and the conductive structures 410, the first sub-electrodes 610 above the first light-emitting units 510 with a greater thickness have a greater overlap area with the conductive structures 410, that is, the first sub-electrodes 610 above the first light-emitting units 510 with a greater thickness have a greater direct contact area with the conductive structures 410. Under the influence of the first light-emitting units with a greater impedance, the effective electrical connection area between the first sub-electrodes 610 and the conductive structures 410 can be greater, so as to better reduce the resistance of the display panel 10 and improve the working stability of the display panel 10.
