That is, the light emitting layer 50 of the first light emitting unit is the first light emitting layer 51, the light emitting layer 50 of the second light emitting unit is the second light emitting layer 52, and the light emitting layer 50 of the third light emitting unit is the third light emitting layer 53.
[0107] Exemplarily, the first light emitting layer 51 can emit blue light, that is, the first light emitting layer 51 corresponds to a B pixel, the second light emitting layer 52 can emit green light, that is, the second light emitting layer 52 corresponds to a G pixel, and the third light emitting layer 53 can emit red light, that is, the second light emitting layer 52 corresponds to an R pixel.

That is, part of the isolation openings in the plurality of isolation openings is the first isolation opening 11, another part of the isolation openings is the second isolation opening 12, and the rest of the isolation openings is the third isolation opening 13.
[0109] Please refer to Figure 2 In the related art, the first encapsulation layer 70 includes a wrapping edge 701, the wrapping edge 701 is located on the side of the isolation structure 40 away from the substrate 10, the orthographic projection of the wrapping edge 701 on the substrate 10 is located within the orthographic projection of the isolation structure 40 on the substrate 10, and the wrapping edge 701 and the isolation structure 40 have a gap 80 (such as a first gap 81, a second gap 82 or a third gap 83) therebetween. Optionally, the edge of the gap 80 has an opening, that is, the opening of the gap 80 is formed on the edge of the gap 80. Optionally, the opening of the gap 80 can also be formed at other positions of the gap 80. For example, the opening of the gap 80 can be formed at the middle position of the gap 80.
[0110] The display panel 100 is processed by forming the first electrode 20 on the substrate 10, then forming the pixel definition layer 30 (PDL), and then forming the light-emitting layer 50 and the second electrode 60 in the isolation opening. Alternatively, the process of forming the light-emitting layer 50 and the second electrode 60 in the isolation opening is: sequentially forming the first light-emitting layer 51 and the corresponding second electrode 60 in the first isolation opening 11, forming the second light-emitting layer 52 and the corresponding second electrode 60 in the second isolation opening 12, and forming the third light-emitting layer 53 and the corresponding second electrode 60 in the third isolation opening 13. The first encapsulation layer 70 is also used for encapsulation when the first light-emitting layer 51, the second light-emitting layer 52, and the third light-emitting layer 53 are formed.
[0111] In the embodiments of the present application, the light-emitting layer 50 and the second electrode 60 are evaporated on the substrate 10, then the first encapsulation layer 70 is formed by chemical vapor deposition (CVD), and then the light-emitting layer 50, the second electrode 60, and the first encapsulation layer 70 are formed in the isolation opening by the processes of exposure, development, and etching. The present application does not limit this.
[0112] The inventors found that after the first light-emitting layer 51 is formed in the first isolation opening 11, the etching liquid and the stripping liquid of the photoresist can easily enter the gap 80 (the first gap 81) through the opening and then invade the light-emitting layer 50 (the first light-emitting layer 51) when the subsequent process forms the second light-emitting layer 52, which causes the light-emitting layer 50 to be damaged and the light-emitting unit (the first light-emitting unit) to easily produce dark spots / gray spots when emitting light.
[0113] Similarly, after the second light-emitting layer 52 is formed in the second isolation opening 12, the etching liquid and the stripping liquid of the photoresist can easily enter the gap 80 (the second gap 82) through the opening and then invade the light-emitting layer 50 (the second light-emitting layer 52) when the subsequent process forms the third light-emitting layer 53, which causes the light-emitting layer 50 to be damaged and the light-emitting unit (the second light-emitting unit) to easily produce dark spots / gray spots when emitting light.
[0114] Please refer to Figure 3To solve the problem found by the inventor, in some embodiments, the display panel 100 provided by the embodiments of the present application is provided with a blocking structure between the edge cover 701 and the isolation structure 40, so that the blocking structure blocks at least part of the opening of the gap 80. In this way, the display panel 100 provided by the embodiments of the present application can avoid the liquid in the subsequent process from invading the light-emitting unit encapsulated by the first encapsulation layer 70 through the gap 80, so as to avoid the damage of the light-emitting unit encapsulated by the first encapsulation layer 70. Therefore, the display panel 100 provided by the embodiments of the present application can avoid the generation of dark spots / grey spots when the light-emitting unit emits light, which is conducive to improving the reliability and light-emitting effect of the light-emitting unit, and further conducive to improving the use performance / process performance of the display device.
[0115] Therefore, the display panel 100 provided by the embodiments of the present application can improve the use performance / process performance of the display device.
[0116] In other embodiments, the display panel 100 provided by the embodiments of the present application further includes a blocking structure, the blocking structure is connected with the edge cover 701, and the blocking structure blocks at least part of the opening of the gap 80. Similarly, the blocking structure provided by the embodiments of the present application can avoid the liquid in the subsequent process from invading the light-emitting unit encapsulated by the first encapsulation layer 70 through the gap 80, so as to avoid the damage of the light-emitting unit encapsulated by the first encapsulation layer 70.
[0117] In some embodiments, the normal projection of the edge of the gap 80 on the substrate 10 is located in the normal projection of the blocking structure on the substrate 10.
[0118] In this way, the blocking structure can cross the opening at the edge of the gap 80, and the blocking effect is better. Therefore, the display panel 100 provided by the embodiments of the present application can improve the blocking effect of the blocking structure on the gap 80.
[0119] For example, the blocking structure includes the second electrode 60. That is, the display panel 100 provided by the embodiments of the present application is provided with the second electrode 60 between the edge cover 701 and the isolation structure 40, and the second electrode 60 is used to block the opening of the gap 80. It can be understood that in the subsequent process, when the light-emitting unit is formed at the position corresponding to the opening, the second electrode 60 at the opening of the gap 80 can be reserved, so that the second electrode 60 blocks the opening of the gap 80. In this way, the blocking structure does not need to be set by additional process, and the cost can be avoided.
[0120] For example, the blocking structure includes the second electrode 60 and the light-emitting layer 50. Similarly, the display panel 100 provided by the embodiments of the present application is provided with the second electrode 60 and the light-emitting layer 50 between the edge cover 701 and the isolation structure 40, and the second electrode 60 and the light-emitting layer 50 are used to block the opening of the gap 80. In this way, the blocking structure does not need to be set by additional process, and the cost can be avoided.
[0121] Please refer to Figure 1 and Figure 3 In some embodiments, the first light emitting unit is located in the first isolation opening 11, and the second light emitting unit is located in the second isolation opening 12. The first encapsulation layer 70 includes a first encapsulation part 71 and a second encapsulation part 72. The orthographic projection of the first light emitting unit on the substrate 10 is located in the orthographic projection of the first encapsulation part 71 on the substrate 10, and the orthographic projection of the second light emitting unit on the substrate 10 is located in the orthographic projection of the second encapsulation part 72 on the substrate 10. That is, the first encapsulation part 71, the first light emitting unit, and the first isolation opening 11 correspond, and the second encapsulation part 72, the second light emitting unit, and the second isolation opening 12 correspond.
[0122] The first encapsulation part 71 includes a first edge wrapping part 711 located on the side of the isolation structure 40 away from the substrate 10, and the orthographic projection of the first edge wrapping part 711 on the substrate 10 is located in the orthographic projection of the isolation structure 40 on the substrate 10. The second encapsulation part 72 includes a second edge wrapping part 721 located on the side of the isolation structure 40 away from the substrate 10, and the orthographic projection of the second edge wrapping part 721 on the substrate 10 is located in the orthographic projection of the isolation structure 40 on the substrate 10.
[0123] The first edge wrapping part 711 and the isolation structure 40 have a first gap 81, and the second edge wrapping part 721 and the isolation structure 40 have a first blocking structure. The edge of the first gap 81 has an opening, and the first blocking structure blocks the opening of the first gap 81.
[0124] In this way, the first blocking structure can block the first gap 81 between the first edge wrapping part 711 and the isolation structure 40, avoid damaging the first light emitting unit encapsulated by the first edge wrapping part 711, and avoid the first light emitting unit producing dark spots / grey spots when emitting light. This is conducive to improving the reliability and light emitting effect of the first light emitting unit, and further conducive to improving the use performance / process performance of the display device. In addition, the second edge wrapping part 721 can protect the first blocking structure, and the reliability of the first blocking structure can be improved.
[0125] Illustratively, the orthographic projection of the edge of the first gap 81 on the substrate 10 is located in the orthographic projection of the first blocking structure on the substrate 10. In this way, the first blocking structure can cross the opening at the edge of the first gap 81, and the blocking effect is better. Therefore, the display panel 100 provided by the present application can improve the blocking effect of the first blocking structure on the gap 80.
[0126] Exemplarily, the first barrier structure comprises the second electrode 60 of the second light emitting unit. It can be understood that in the subsequent process, when the second light emitting unit is formed in the second isolation opening 12, the second electrode 60 at the opening of the first gap 81 can be reserved, so that the second electrode 60 blocks the opening of the gap 80. In this way, the barrier structure can be set without additional processes, and additional costs can be avoided.
[0127] Exemplarily, the first barrier structure further comprises the second electrode 60 and the second light emitting layer 52 of the second light emitting unit. Similarly, in the subsequent process, when the second light emitting unit is formed in the second isolation opening 12, the second electrode 60 and the second light emitting layer 52 at the opening of the first gap 81 can be reserved, so that the second electrode 60 and the second light emitting layer 52 block the opening of the gap 80. In this way, the barrier structure can be set without additional processes, and additional costs can be avoided.
[0128] Please refer to Figure 4 and Figure 5 In some embodiments, the first encapsulation layer 70 further comprises a fourth edge wrapping 732, a normal projection of the fourth edge wrapping 732 on the substrate 10 is located in a normal projection of the isolation structure 40 on the substrate 10, the fourth edge wrapping 732 is located on a side of the second edge wrapping 721 away from the substrate 10, and the fourth edge wrapping 732 and the second edge wrapping 721 have a third barrier structure.
[0129] The normal projection of the third barrier structure on the substrate 10 overlaps the normal projection of the first barrier structure on the substrate 10, and the normal projection of the third barrier structure on the substrate 10 is located in the normal projection of the fourth edge wrapping 732 on the substrate 10.
[0130] In this way, the third barrier structure can block the opening of the first gap 81 together with the first barrier structure, which can further help to improve the reliability and light emitting effect of the first light emitting unit, and further help to improve the use performance / process performance of the display device. In addition, the fourth edge wrapping 732 can protect the third barrier structure, and the reliability of the third barrier structure can be improved.
[0131] It can be understood that the third encapsulation part 73 further comprises the fourth edge wrapping 732.
[0132] Exemplarily, a normal projection of an edge of the first gap 81 on the substrate 10 is located in a normal projection of the third barrier structure on the substrate 10. In this way, the third barrier structure can cross the opening at the edge of the first gap 81, and the blocking effect is better. Therefore, the display panel 100 provided by the present application can improve the blocking effect of the third barrier structure on the first gap 81.
[0133] Exemplarily, the third barrier structure comprises the second electrode 60 of the third light emitting unit. It can be understood that in the subsequent process, when the third light emitting unit is formed in the third isolation opening 13, the second electrode 60 on the second package edge 721 away from the substrate 10 side of the first barrier structure can be reserved, so that the second electrode 60 and the second barrier structure jointly block the opening of the first gap 81. In this way, the barrier structure can be set without additional process, and additional cost can be avoided.
[0134] Exemplarily, the third barrier structure further comprises the second electrode 60 and the third light emitting layer 53 of the third light emitting unit. Similarly, in the subsequent process, when the third light emitting unit is formed in the third isolation opening 13, the second electrode 60 and the third light emitting layer 53 on the second package edge 721 away from the substrate 10 side of the first barrier structure can be reserved, so that the second electrode 60 and the third light emitting layer 53 and the first barrier structure jointly block the opening of the first gap 81. In this way, the barrier structure can be set without additional process, and additional cost can be avoided.

[0138] In this way, the second blocking structure can block the second gap 82 between the second package edge 721 and the isolation structure 40, so as to avoid damage to the second light emitting unit encapsulated by the second package edge 721. Therefore, the display panel 100 provided in the embodiments of the present application can avoid the second light emitting unit from generating dark spots / grey spots when emitting light, which is conducive to improving the reliability and light emitting effect of the second light emitting unit, and thus is conducive to improving the use performance / process performance of the display device.

Therefore, the display panel 100 provided in the present application can improve the blocking effect of the second blocking structure on the gap 80.
[0140] Exemplarily, the second blocking structure includes the second electrode 60 of the third light emitting unit. It can be understood that in the subsequent process, when the third light emitting unit is formed in the third isolation opening 13, the second electrode 60 at the opening of the second gap 82 can be reserved, so that the second electrode 60 blocks the opening of the gap 80. In this way, the blocking structure does not need to be additionally set by the process, and the cost can be avoided to be additionally increased.

[0146] It should be noted that the third gap 83 is between the third edge 731 of the third encapsulation part 73 of the display panel 100 and the isolation structure 40. After the third light emitting unit is formed, there is no subsequent process of forming a light emitting unit, and the influence of the third gap 83 on the third light emitting unit is small, so the opening of the third gap 83 can not be blocked.
