Figure 5 1 is a partial cross-sectional schematic diagram of a display panel 10 according to another embodiment of the present application. For example, Figure 5 Can Figure 4 Schematic diagram of the cross section at BB in the middle.

[0111] In some other optional embodiments, such as Figure 4 and Figure 5 As shown, the edge of the third orthographic projection S3 may be located within the orthographic projection of the isolation structure 300 on the substrate 100 .

[0112] By setting the edge of the third orthographic projection S3 to be located within the orthographic projection of the isolation structure 300 on the substrate 100, the edge of the first electrode 410 of the third device 400c can extend to the bottom of the isolation structure 300. The first electrode 410 of the third device 400c extending to the bottom of the isolation structure 300 can play a certain flattening role, so that during the preparation process of the display panel 10, other film layer structures subsequently formed in the third isolation opening 301c can be better connected with the edge of the isolation structure 300 facing the third isolation opening 301c, thereby better improving the working stability of the display panel 10.

[0113] Optionally, the orthographic projection of the wall of the third isolation opening 301c on the substrate 100 may be located within the third orthographic projection S3, so that the edge of the first electrode 410 of the third device 400c may extend below the wall of the third isolation opening 301c, and the first electrode 410 of the third device 400c extending below the wall of the third isolation opening 301c may play a certain flattening role, so that during the preparation process of the display panel 10, other film layer structures subsequently formed in the third isolation opening 301c may be better connected with the wall of the third isolation opening 301c, thereby better improving the working stability of the display panel 10.

[0114] Optionally, the widths of the isolation structure 300 around the first isolation opening 301a, the second isolation opening 301b and the third isolation opening 301c may be approximately or equal. For example, the widths of the orthographic projections of the isolation structure 300 around the first isolation opening 301a, the second isolation opening 301b and the third isolation opening 301c on the substrate 100 may be approximately or equal.

[0115] In some optional embodiments, the material of the isolation structure 300 includes a conductive material, and the second electrode 430 can be connected to the isolation structure 300, so that the second electrodes 430 between adjacent light-emitting devices 400 can be electrically connected through the isolation structure 300 to facilitate control of the second electrode 430.

[0116] In some optional embodiments, the orthographic projection of the wall surface of the communication hole 100 a on the substrate 100 may be located within the orthographic projection of the isolation structure 300 on the substrate 100 .

[0117] Optionally, a portion of the first electrode 410 may extend between the isolation structure 300 and the via 100 a , so that the first electrode 410 is electrically connected to the transistor 151 through the via 100 a .

[0118] In these optional embodiments, by arranging the communication hole 100a below the isolation structure 300 and not arranging it on the side of the isolation structure 300 facing the isolation opening 301, the edge portion of the isolation structure 300 facing the isolation opening 301 is not easily affected by the arrangement of the communication hole 100a and becomes concave, so that when the isolation structure 300 is etched, the etching material is not likely to cause abnormal etching on the edge of the isolation structure 300, thereby improving the preparation yield of the isolation structure 300. In addition, the second electrode 430 is not easily affected by the arrangement of the communication hole 100a, and the second electrode 430 can be connected to the edge of the isolation structure 300 facing the isolation opening 301 more smoothly, thereby improving the connection reliability between the second electrode 430 and the isolation structure 300.

[0119] In some embodiments of the present application, by setting the edge of the second orthographic projection S2 to be located within the orthographic projection of the isolation structure 300 on the substrate 100, the first electrode 410 of the second device 400b extending to the bottom of the isolation structure 300 can play a better flattening role, so that the second electrode 430 of the isolation structure 300 near the peripheral side of the second isolation opening 301b can have a better degree of flatness, so that the second electrode 430 can be better connected to the wall of the second isolation opening 301b, thereby better improving the working stability of the display panel 10.

[0120] Similarly, when the edge of the third orthographic projection S3 is set to be located within the orthographic projection of the isolation structure 300 on the substrate 100, the first electrode 410 of the third device 400c extending to the bottom of the isolation structure 300 can play a better flattening role, so that the second electrode 430 can be better connected to the wall of the third isolation opening 301c, which can further improve the working stability of the display panel 10.

[0121] In some embodiments of the present application, by setting the edge of the first electrode 410 of a portion of the light-emitting devices 400 to extend below the isolation structure 300, and at least part of the edge of the first electrode 410 of another portion of the light-emitting devices 400 not extending below the isolation structure 300, the light transmittance and operating stability of the display panel 10 can be better controlled, that is, the display panel 10 can have both good light transmittance and operating stability.

[0122] Exemplarily, whether the edge of the first electrode 410 of the light-emitting device 400 extends to below the isolation structure 300 may be set according to the size difference between the isolation openings 301 .

[0123] In some optional embodiments, the orthographic projection area of ​​the first isolation opening 301 a on the substrate 100 may be greater than the orthographic projection area of ​​the second isolation opening 301 b on the substrate 100 .

[0124] Optionally, the orthographic projection area of ​​the first isolation opening 301 a on the substrate 100 may refer to the area of ​​a region enclosed by the orthographic projection of the wall surface of the first isolation opening 301 a on the substrate 100 .

[0125] Optionally, the orthographic projection area of ​​the second isolation opening 301 b on the substrate 100 may refer to the area of ​​a region enclosed by the orthographic projection of the wall surface of the second isolation opening 301 b on the substrate 100 .

[0126] Optionally, the orthographic projection area of ​​the third isolation opening 301c on the substrate 100 is larger than the orthographic projection area of ​​the second isolation opening 301b on the substrate 100 , and / or the orthographic projection area of ​​the third isolation opening 301c on the substrate 100 is smaller than the orthographic projection area of ​​the first isolation opening 301a on the substrate 100 .

[0127] Optionally, the orthographic projection area of ​​the third isolation opening 301 c on the substrate 100 may refer to the area of ​​a region enclosed by the orthographic projection of the wall surface of the third isolation opening 301 c on the substrate 100 .

[0128] Optionally, the luminous color of the first device 400a is blue, and / or the luminous color of the second device 400b is green, and / or the luminous color of the third device 400c is red. The first isolation opening 301a with a larger size can be conveniently arranged with the luminous functional layer 420 of the first device 400a with a larger size, which is beneficial to increase the luminous area of ​​the first device 400a with a blue luminous color, and is beneficial to reduce the current passing through the luminous functional layer 420 in the first device 400a, so as to better reduce the luminous attenuation speed of the luminous functional layer 420 in the first device 400a.

[0129] In these optional embodiments, the first isolation opening 301a with a larger size can facilitate improving the light transmission performance of the display panel 10. In addition, since the first isolation opening 301a has a larger size, it can facilitate the realization that at least part of the edge of the first orthographic projection S1 is spaced from the orthographic projection of the isolation structure 300 on the substrate 100, and it is convenient to realize that the orthographic projection of the wall surface of the first isolation opening 301a on the substrate 100 does not overlap with at least part of the first orthographic projection S1, that is, it is easy to realize that at least part of the edge of the first electrode 410 in the first device 400a does not extend below the isolation structure 300, so that light can easily pass through the display panel 10 through the gap between the isolation structure 300 and the first electrode 410 of the first device 400a, thereby being able to better improve the light transmission performance of the display panel 10.

[0130] Since the size of the second isolation opening 301b is relatively small, it is convenient to realize that the edge of the second orthographic projection S2 is located within the orthographic projection of the isolation structure 300 on the substrate 100, and it is convenient to realize that the orthographic projection of the wall of the second isolation opening 301b on the substrate 100 is located within the second orthographic projection S2, that is, it is easier to realize that the edge of the first electrode 410 of the second device 400b extends to the bottom of the isolation structure 300, so that the first electrode 410 of the second device 400b can play a flattening role, so that the second electrode 430 can be better connected to the isolation structure 300, thereby improving the working stability of the display panel 10.

[0131] Similarly, the relative position relationship between the first electrode 410 of the third device 400 c and the isolation structure 300 may also be set according to the specific size of the third isolation opening 301 c.

[0132] For example, Figure 2 and Figure 3 As shown, when the orthographic projection area of ​​the third isolation opening 301c on the substrate 100 is more similar to the orthographic projection area of ​​the first isolation opening 301a on the substrate 100, for example, there is a first difference between the orthographic projection area of ​​the third isolation opening 301c on the substrate 100 and the orthographic projection area of ​​the first isolation opening 301a on the substrate 100, and there is a second difference between the orthographic projection area of ​​the third isolation opening 301c on the substrate 100 and the orthographic projection area of ​​the second isolation opening 301b on the substrate 100. When the first difference is less than the second difference, the third orthographic projection S At least part of the edge of the first electrode 410 in the third device 400c may be spaced from the orthographic projection of the isolation structure 300 on the substrate 100, and / or the orthographic projection of the wall surface of the third isolation opening 301c on the substrate 100 may not overlap with at least part of the third orthographic projection S3, which can facilitate the implementation of at least part of the edge of the first electrode 410 in the third device 400c not extending below the isolation structure 300, so that light can also easily pass through the display panel 10 through the gap between the isolation structure 300 and the first electrode 410 of the third device 400c, thereby better improving the light transmittance performance of the display panel 10.

[0133] For example, Figure 4 and Figure 5As shown, when the orthographic projection area of ​​the third isolation opening 301c on the substrate 100 is closer to the orthographic projection area of ​​the second isolation opening 301b on the substrate 100, for example, when the first difference is greater than the second difference, the edge of the third orthographic projection S3 may be located within the orthographic projection of the isolation structure 300 on the substrate 100, and / or, the orthographic projection of the wall of the third isolation opening 301c on the substrate 100 may be located within the third orthographic projection S3, which can facilitate the extension of the edge of the first electrode 410 of the third device 400c to the bottom of the isolation structure 300, so that the second electrode 430 and the isolation structure 300 can be better connected, thereby greatly improving the working stability of the display panel 10.

The second opening 301ab disposed around the first opening 301aa can be helpful in increasing the size of the first isolation opening 301a, thereby facilitating the light transmission performance of the display panel 10, and can facilitate the realization of the spacing between at least part of the edge of the first orthographic projection S1 and the orthographic projection of the isolation structure 300 on the substrate 100, and facilitate the realization that the orthographic projection of the wall surface of the first isolation opening 301a on the substrate 100 does not overlap with at least part of the first orthographic projection S1.

For the convenience of description, the following embodiments are described by taking the isolation structure 300 being set on the side of the pixel defining portion 210 away from the substrate 100 as an example.

[0200] Figure 6It is a partial structural schematic diagram of an orthographic projection of an isolation structure 300 and a pixel opening 211 on a substrate 100 according to an embodiment of the present application.

[0206] In these optional embodiments, the first pixel port 211a having a larger size can expose a larger area of ​​the first electrode 410 of the first device 400a, so that the first electrode 410 and the light-emitting functional layer 420 in the first device 400a can have a larger connection area, which is beneficial to increasing the light-emitting area of ​​the first device 400a with a blue light-emitting color, and is beneficial to reducing the current passing through the light-emitting functional layer 420 in the first device 400a, thereby effectively reducing the light-emitting attenuation rate of the light-emitting functional layer 420 in the first device 400a.

[0209] For example, Figure 6 The d1 in the figure may indicate the maximum distance between the orthographic projection edge of the first pixel opening 211a on the substrate 100 and the orthographic projection edge of the first isolation opening 301a on the substrate 100. Figure 6 The d2 in the figure may indicate the maximum distance between the orthographic projection edge of the second pixel opening 211 b on the substrate 100 and the orthographic projection edge of the second isolation opening 301 b on the substrate 100 .
