[0042] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments are not limiting to the scope of the present application unless otherwise specifically stated.

[0043] The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the scope of the application, its application, or uses.

[0044] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail herein. However, where appropriate, such techniques, methods, and devices can be considered part of the specification.

[0045] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Thus, other examples of the exemplary embodiments can have different values.

[0046] It should be noted that like numbers and letters refer to like items throughout the following drawings, and that, as such, no further discussion of the same will be made.

[0047] The inventors discovered that in CFOT (Color Filter On TFE, polarizer-free technology) type display panels, it is often necessary to set light-transmitting holes in certain areas of the display panel to cooperate with optical FOD (Fingerprint On Display, under-display fingerprint recognition technology) or ambient light sensors. These light-transmitting holes include openings that penetrate the thickness of the BM (Black Matrix, light-shielding) layer. The presence of these openings exposes the highly reflective cathodes set in the underlying film layer. As a result, light incident through the openings is reflected by the highly reflective cathodes and then re-exits through the openings, leading to an increase in the overall reflectivity of the display panel and consequently a deterioration in the display effect.

[0048] In view of this, the present invention provides a display panel and a display device for avoiding the problem of deterioration of display effect when a light-transmitting hole is provided in the BM layer.

[0049] Figure 1 The image shown is a schematic diagram of a display panel provided in an embodiment of this application. Figure 2 The image shown is provided in an embodiment of this application. Figure 1 A cross-sectional view of XX' Figure 3 The image shown is of this application. Figure 1 A perspective view of the hole assembly provided in the image. Figure 4 The image shown is provided in an embodiment of this application. Figure 3 A cross-sectional view of AA'. Figure 5 The image shown is provided in an embodiment of this application. Figure 3 Another cross-sectional view of AA'. Figure 6 The image shown is provided in an embodiment of this application. Figure 3 For another cross-sectional view of AA', please refer to... Figures 1-6 This application provides a display panel 100, including a substrate 41, a first insulating layer 42 disposed on one side of the substrate 41, a first electrode layer 43 disposed on the side of the first insulating layer 42 away from the substrate 41, and a light-shielding layer 44 disposed on the side of the first electrode layer 43 away from the first insulating layer 42.

[0050] Hole assembly 20 includes corresponding first opening 21 and second opening 22;

[0051] The first opening 21 penetrates the light-shielding layer 44 in a direction perpendicular to the plane of the substrate 41;

[0052] The second opening 22 is located at least in the first insulating layer 42;

[0053] Among them, the hole combination 20 is an asymmetric design; and / or,

[0054] The first electrode layer 43 at the position corresponding to the second opening 22 is a non-planar structure.

[0055] Specifically, the substrate 41, the first insulating layer 42, the first electrode layer 43 and the light shielding layer 44 are laminated in the display panel 100, wherein the light shielding layer 44 and the first electrode layer 43 comprise a light transmission area 45 with a certain thickness between them, which is used to allow light to pass through without affecting the direction of the light.

[0056] In addition, as shown in the figure, Figure 2 Specifically, the first insulating layer 42 can comprise a first sub-insulating layer 424, a second sub-insulating layer 423, a planarization layer 422 and a pixel defining layer 421 arranged in sequence. The display panel 100 further comprises a driving circuit, wherein the driving transistor 90 comprised in the driving circuit can be arranged in the first insulating layer 42, specifically, the semiconductor layer of the driving transistor 90 can be arranged in the first sub-insulating layer 424, the gate of the driving transistor 90 can be arranged in the second sub-insulating layer 423, and the source / drain of the driving transistor 99 can be arranged in the planarization layer 422; the light emitting element 70 is arranged in the pixel defining layer 421, and the driving transistor 90 is electrically connected with the light emitting element 70, for controlling whether the electrical signal can be transmitted to the light emitting element 70, so as to control the light emitting element 70 to be in a light emitting state or an extinguishing state. In addition, the light shielding layer 44 is provided with an opening corresponding to the light emitting element 70, for the emission of light emitted by the light emitting element 70, so as to realize the normal display function of the display panel 100; wherein the color resistance 74 can be arranged in the opening on the upper side of the light emitting element 70, so as to realize the diversified color display of the display panel 100; wherein the light emitting element 70 comprises a first electrode 71, a light emitting layer 72 and a second electrode 73, the light emitting layer 72 is located between the first electrode 71 and the second electrode 73, and the first electrode layer 43 comprises the first electrode 71. It should be further pointed out that, Figures 4-6 The 45 shown in the figure corresponds to the encapsulation layer in the display panel 100, which can be a rigid encapsulation; if the 45 shown in the figure is formed by laminating inorganic insulating layer, organic insulating layer and inorganic insulating layer, it can be a TFE (thin film encapsulation).

[0057] The display panel 100 includes at least one hole combination 20, each hole combination 20 includes oppositely arranged first and second openings 21 and 22. The oppositely arranged first and second openings 21 and 22 are specifically partially overlapped in the projection of the substrate 41. That is, the projections of the first and second openings 21 and 22 on the plane of the display panel 100 have an overlapping area, so that the functions of the components arranged at the first and / or second openings 21 and 22 can be normally used. The first and second openings 21 and 22 in the hole combination 20 cannot be two openings with a spacing in the projection on the plane of the display panel 100. The first opening 21 is arranged in the light shielding layer 44, and the first opening 21 is formed by penetrating the entire thickness of the light shielding layer 44, so that light can be incident / emitted through the first opening 21. The second opening 22 is arranged in the first insulating layer 42. The second opening 22 can be formed by penetrating the entire first insulating layer 42, or the second opening 22 can be formed by removing part of the first insulating layer 42 away from the substrate 41.

[0058] Based on the structure of the display panel 100, an optional embodiment of the present application is that the first and second openings 21 and 22 in each hole combination 20 are asymmetrically arranged. From the top view of the display panel 100, when the first and second openings 21 and 22 are both circular, the center 210 of the first opening 21 and the center 220 of the second opening 22 can be arranged not to overlap in the projection on the plane of the substrate 41. When the first and second openings 21 and 22 are both square, the center point of the first opening 21 and the center point of the second opening 22 can be arranged not to overlap in the projection on the plane of the substrate 41 (not shown). At this time, the present application does not limit whether the projection area of the first opening 21 on the plane of the substrate 41 is the same as the projection area of the second opening 22 on the plane of the substrate 41, as long as the projections of the first and second openings 21 and 22 on the plane of the substrate 41 are not completely overlapped. Specifically, from another observation angle, in the direction of viewing the paper image of the accompanying drawings of the present application, as shown in FIG. 2, the first and second openings 21 and 22 in each hole combination 20 are asymmetrically arranged. Figures 4-6In the cross-sectional view shown, the first opening 21 is disposed to the left of the overall hole combination 20 in the width occupied by the hole combination 20, and the second opening 22 is disposed to the right of the overall hole combination 20 in the width occupied by the hole combination 20; or in other words, the second opening 22 in one hole combination 20 is offset to the right relative to the position of the first opening 21. In this way, the cross-sectional view of the hole combination 20 including the first opening 21 and the second opening 22 is an asymmetric structure, thereby achieving an asymmetric design of the hole combination 20.

[0059] As Figure 5 In the embodiment shown, the present application presents an asymmetric design of the cross-sectional view of both the first opening 21 and the second opening 22, so that the light rays incident on the surface of the first electrode layer 43 at the corresponding position of the second opening 22 from the first opening 21 can be at least partially reflected to the light-blocking layer 44 beside the first opening 21 and absorbed by the light-blocking layer 44. Specifically, as Figure 5 As shown, the reflected light rays 99 shown by the small arrows are reflected light rays 99 formed on the surface of the first electrode layer by the corresponding incident light rays in the case of a symmetric design of the second opening and the first opening, but Figure 5 As shown in the middle, in the direction of viewing the paper image of the accompanying drawings of the present application, the present application sets the second opening 22 at a position offset to the right of the first opening 21, so that, as Figure 5 As shown, the corresponding incident light rays of the reflected light rays 99 are reflected by the first electrode layer 43 to the surface of the light-blocking layer 44, so that the reflected light rays formed by the incident light rays are absorbed by the light-blocking layer 44, thereby reducing the number of reflected light rays that exit from the first opening 21. Similarly, the asymmetric design of the hole combination 20 of the present application can cause the light rays incident on the surface of the first electrode layer 43 at the corresponding position of the second opening 22 from the first opening 21 to be partially reflected by the first electrode layer 43 to the light-blocking layer 44 instead of being reflected to the first opening 21 to exit, thereby reducing the number of light rays that exit from the first opening 21 after being reflected by the first electrode layer 43, weakening the influence of the reflected light rays on the display effect of the display panel 100, and being conducive to improving the display uniformity of the display panel 100 and thus improving the user experience.

[0060] It should be noted that, since the position for setting the hole combination 22 is limited, in order to avoid excessive occupation of the space of the display panel 100 by the setting of the hole combination 22 and at the same time achieve the effect of reducing the reflectivity of the display panel, the present application sets the first opening 21 and the second opening 22 to be misaligned, i.e., as Figure 5The first aperture 21 and the second aperture 22 are arranged as shown to achieve the technical effect of reducing the number of light rays emitted from the first aperture 21 after being reflected by the first electrode layer 43, thereby avoiding the problem of display panel 100 reflectivity deterioration caused by reflected light, and also avoiding excessive increase in the space required for the aperture combination 22.

[0061] In some optional embodiments of the present application, as shown in Figure 5 The first aperture 21 and the second aperture 22 are both circular in the orthographic projection of the substrate 41, and the diameter of the first aperture 21 is the same as that of the second aperture 22. At this time, when the first aperture 21 and the second aperture 22 are designed asymmetrically, i.e., there is a region (as shown in Figure 4 the orthographic projection of the substrate 41, the area of the overlapping region of the second aperture 22 and the first aperture 21 is reduced, so that the light rays emitted from the first aperture 21 to the first electrode layer 43 will not all fall within the second aperture 22.

[0062] In some optional embodiments of the present application, as shown in Figure 6 The first electrode layer 43 at the corresponding position of the part of the second aperture 22 to the right of the edge line of the first aperture 21 will reflect part of the incident light to the side of the light shielding layer 44 and be absorbed by it; that is, part of the light rays incident into the second aperture 22 can be reflected by the first electrode layer 43 to the light shielding layer 44 and be absorbed, and part of the light rays incident into the second aperture 22 at the corresponding overlapping position of the light shielding layer 44 can also be reflected by the first electrode layer 43 to the light shielding layer 44 and be absorbed, thereby reducing the number of light rays emitted from the first aperture 21 after being reflected by the first electrode layer 43.

[0063] Based on the structure of the display panel 100 described above, the present application further provides an optional embodiment as follows: Figure 4It is shown that the first electrode layer 43 arranged at the position corresponding to the second opening 22 is a non-planar structure. The use of the non-planar first electrode layer 43 reflects at least part of the ambient light entering from the first opening 21 to other directions (not towards the direction of the first opening 21). Compared with the planar first electrode layer 43, the part of the first electrode layer 43 changes the exiting direction of the light, so that part of the light that needs to exit from the first opening after being reflected by the planar first electrode layer will change the exiting direction of the light, so that part of the light will be reflected to the side surface close to the light shielding layer 44, and thus be absorbed by the light shielding layer 44, thereby reducing the number of light rays exiting from the first opening 21 after being reflected by the first electrode layer 43. This is conducive to weakening the influence of reflected light on the display effect of the display panel 100, thereby improving the display uniformity of the display panel 100, and further improving the user experience.

[0064] For example Figures 1-6 It is shown that if the second opening 22 is not arranged, the first electrode layer 43 still presents a planar structure, and the incident light 98 will be reflected by the planar first electrode layer 43 and exit from the first opening 21. However, the present application arranges the second opening 22, so that the corresponding first electrode layer 43 at the position of the second opening 22 presents a non-planar structure. At this time, the incident light 98 will be reflected by the non-planar first electrode layer 43 to the side surface close to the light shielding layer, and thus be absorbed by the light shielding layer 44. Similarly, the present application arranges the first electrode layer 43 at the position corresponding to the second opening 22 to be a non-planar structure, which can adjust the reflection direction of part of the incident light, thereby reducing the number of light rays exiting from the first opening 21 after being reflected by the first electrode layer 43. This is conducive to weakening the influence of reflected light on the display effect of the display panel 100, improving the display uniformity of the display panel 100, and further improving the user experience.

[0065] In addition, the present application can also arrange the first opening 21 and the second opening 22 in the hole combination 20 to be asymmetrically designed, and arrange the first electrode layer 43 at the position corresponding to the second opening 22 to be a non-planar structure. In this way, the above technical effect of reducing the number of light rays exiting from the first opening 21 after being reflected by the first electrode layer 43 can be achieved, the influence of reflected light on the display effect of the display panel 100 can be weakened, and the display uniformity of the display panel 100 can be improved.

[0066] It should be further understood that the ambient light entering from the first opening 21 can be at least partially reflected by the non-planar first electrode layer 43 in a direction other than towards the first opening 21 because the specific form of the non-planar structure of the first electrode layer 43 on the side facing the first opening 21 is adjusted. Furthermore, when the surface of the first electrode layer 43 provided by the application reflects the incident light, the incident angle and the reflection angle of the light are equal, that is, the incident light is reflected in a specific direction by the non-planar structure of the first electrode layer 43, which realizes the customized direction of the reflection of the ambient light. Therefore, the number of light rays reflected by the first electrode layer 43 and then exiting from the first opening 21 can be reduced. The difference between the application and the way of adjusting the reflection direction of light by using scattering particles is that the application reflects light in a specific direction, that is, when the first electrode layer 43 reflects the incident light, it reflects in a specific direction according to the reflection law that the reflection angle is equal to the incident angle, that is, the reflection angle of the light is equal to its incident angle, and the "specific direction" here refers to the reflection direction of the light corresponding to the reflection angle equal to its incident angle. For scattering particles, light is scattered in different directions, and the reflection direction of the light is not specific. The scattering particles cannot reduce the number of light rays reflected to the first opening 21, and cannot achieve the technical effect of weakening the reflected light on the overall display effect of the display panel 100.

[0067] It should be further understood that the display panel 100 includes a plurality of arrayed sub-pixels 30, and the application provides a first opening 21 that can be selectively arranged beside the sub-pixel 30 without overlapping the sub-pixel 30. In addition, the first opening 21 can also be arranged to overlap the sub-pixel 30 according to requirements, which is not limited by the application.

[0068] It should be noted that the "non-planar" above can be understood as the surface of the first electrode layer 43 at this place having a part not parallel to the plane of the substrate 41, or it can be understood as the surface of the first electrode layer 43 at this place not parallel to the plane of the display panel 100, or when the display panel 100 is placed horizontally, the surface of the first electrode layer 43 at this place is not parallel to the horizontal plane. For example, the surface of the first electrode layer 43 at this place is a curved surface, or the surface of the first electrode layer 43 at this place is an inclined surface, and the included angle between the inclined surface and the plane of the substrate 41 is greater than zero. That is, the first electrode layer 43 includes a part not parallel to the plane of the substrate 41.

[0069] It should be further noted that the first insulating layer 42 described above can be a pixel defining layer in the display panel 100, and the pixel defining layer can be made of an organic material, and can be formed of an organic material such as polyimide (PI), polyamide, benzocyclobutene (BCB), acrylic resin, or phenolic resin.

[0070] The first electrode layer 43 is formed on the side surface of the first insulating layer 42 away from the substrate 41, and the first electrode layer 43 can be made by a vapor deposition process or a sputtering deposition process. The manufacturing process of the first electrode layer 43 is after the first insulating layer 42, the first insulating layer 42 includes an opening defining a light emitting element, and the first electrode layer 43 can cover the position where the first insulating layer 42 is provided with an opening and the position where the first insulating layer 42 is not provided with an opening, that is, the first electrode layer 43 covers the first insulating layer 42 entirely. When a vapor deposition process is used, vapor deposition can be performed entirely, without the need to use a mask with an array of openings. For a display panel 100 including a light emitting element, the related manufacturing sequence can be: first, manufacturing an anode, then manufacturing a pixel defining layer, then manufacturing a light emitting layer, and then manufacturing a first electrode layer 43 and other film layer structures.

[0071] It should be further noted that the non-planar formation of the first electrode layer 43 at the position corresponding to the second opening 22 is achieved by providing a film layer (such as the first insulating layer 42) near the substrate 41 of the display panel 100 with a specific shape structure, without the need to adjust the manufacturing process of the first electrode layer 43. The non-planar part of the first electrode layer 43 is recessed towards the substrate 41 side relative to the horizontal part of the first electrode layer 43 (i.e., a recessed part); or the non-planar part of the first electrode layer 43 is recessed away from the substrate 41 side relative to the horizontal part of the first electrode layer 43 (i.e., a protruding part).

[0072] Please continue to refer to Figure 7 Optionally, in the same hole group 20, the orthographic projection of the second opening 22 on the plane of the substrate 41 at least partially overlaps the orthographic projection of the first opening 21 on the plane of the substrate 41.

[0073] Specifically, as described above, any combination of holes 20 disposed in the display panel 100 in this application can be configured such that the orthographic projection of the second opening 22 on the plane of the substrate 41 at least partially overlaps with the orthographic projection of the first opening 21 on the plane of the substrate 41, thereby ensuring that at least a portion of the ambient light incident through the first opening 21 is irradiated onto the surface of the second opening 22; for example, when a photosensitive element is disposed at the second opening 22, it can be ensured that a portion of the light is irradiated onto the surface of the second opening 22 to achieve the photosensitive function. If a light-emitting element is disposed at the second opening 22, the light emitted by the light-emitting element can be emitted from the corresponding position of the first opening 21 to the outside of the display panel 100 through the overlapping area.

[0074] Figure 3 The image shown is provided in an embodiment of this application. Figure 8 Another cross-sectional view of AA'. Figure 3 The image shown is provided in an embodiment of this application. Figure 1 For another cross-sectional view of AA', please refer to... Figure 3 , Figure 7 and Figure 8 , Figure 7 Optionally, the second opening 22 includes a first sidewall 51 and a second sidewall 52. The first sidewall 51 forms a first angle α1 with the bottom surface of the first insulating layer 42, and the second sidewall 52 forms a second angle α2 with the bottom surface of the first insulating layer 42. Both the first angle α1 and the second angle α2 are acute angles, and the first angle α1 is smaller than the second angle α2.

[0075] Specifically, the second opening 22 provided in this application includes a first sidewall 51 and a second sidewall 52. Since the second opening 22 is formed by removing at least a portion of the first insulating layer 42, both the first sidewall 51 and the second sidewall 52 are formed through the first insulating layer 42.

[0076] like Figure 8 As shown, when the second opening 22 penetrates the first insulating layer 42, a first included angle α1 can be formed between the first sidewall 51 and the bottom surface of the first insulating layer 42, and a second included angle α2 can be formed between the second sidewall 52 and the bottom surface of the first insulating layer 42. This application provides an optional embodiment in which the first included angle α1 and the second included angle α2 are both acute angles, and the included angles of the first included angle α1 and the second included angle α2 can be set to be different, so that the inclination degree of the first sidewall 51 and the inclination degree of the second sidewall 52 are different.

[0077] Or such as Figure 7As shown, when the second opening 22 does not penetrate the first insulating layer 42, but a portion of the thickness of the first insulating layer 42 is removed to form, a first included angle a1 can be formed between the plane where the first side wall 51 is located and the plane where the bottom surface of the first insulating layer 42 is located, where the first included angle a1 refers to the included angle of the side of the first side wall 51 towards the inside of the first insulating layer 42; a second included angle a2 can be formed between the plane where the second side wall 52 is located and the plane where the bottom surface of the first insulating layer 42 is located, where the second included angle a2 refers to the included angle of the side of the second side wall 52 towards the inside of the first insulating layer 42; and in an alternative embodiment, the first included angle a1 and the second included angle a2 are both acute angles, and the degrees of the first included angle a1 and the second included angle a2 can be set to be different, so that the degree of inclination of the first side wall 51 and the degree of inclination of the second side wall 52 are different.

[0078] It should be noted that, as Figure 7 In the embodiment shown, in terms of the direction of the paper image of the drawings of the present application specification, the second opening 22 is arranged to the right of the first opening 21, and the incident light ray 97 is reflected by the first electrode layer 43 to the side of the light shielding layer 44 after being reflected by the surface of the first side wall 51 with an inclination angle a1 after being emitted to the surface of the first electrode layer 43, so that the reflected light ray is absorbed by the light shielding layer 44; but if the inclination angles a5 and a2 of the first side wall are the same, as Figure 9 As shown, the incident light ray 97 will be emitted to the surface of the first electrode layer which is a horizontal plane, and will be reflected by the first electrode layer to the first opening 21. Therefore, by setting the degree of inclination of the first side wall 51 and the degree of inclination of the second side wall 52 to be different, the present application can make more light rays that pass through the first opening 21 and irradiate the first side wall 51 and / or the second side wall 52 be reflected to the side of the light shielding layer 44, rather than being reflected to the first opening 21 for emission, so that the incident light can be reflected in a specific direction by the inclined surface with a specific inclination angle, and the customized directional reflection of ambient light is achieved, so that the number of light rays reflected by the first electrode layer 43 and emitted from the first opening 21 can be reduced, and the influence of the reflected light rays on the display effect of the display panel 100 can be weakened, thereby facilitating the improvement of the display uniformity of the display panel 100, and further improving the user experience.

[0079] In addition, if the incident angle of the light is close to the complementary angle of a5 in the drawing, if the included angle between the first included angle a5 and the second included angle a2 is set to be the same, that is, if the inclination degrees of the first side wall and the second side wall are set to be the same, when the incident light is irradiated to the first side wall, the incident light will be reflected to the first electrode layer on the surface of the second side wall by the first electrode layer on the surface of the first side wall. Since the inclination degrees of the first side wall and the second side wall are the same, the incident light irradiated to the first side wall and the emergent light reflected by the electrode layer on the surface of the second side wall will have symmetrical light paths, so that the incident light incident from the first opening will be reflected to the same position of the first opening by the electrode layer on the surface of the second side wall. Based on the above reasons, in the present application, by setting the inclination degrees of the first side wall 51 and the second side wall 52 to be different, when the incident angle is close to the complementary angle of the first included angle, the light irradiated to the first electrode layer 43 on the surface of the first side wall 51 will be reflected by the first electrode layer 43 on the surface of the first side wall 51, then reach the first electrode layer 43 on the surface of the second side wall 52, and then be reflected by the first electrode layer 43 on the surface of the second side wall 52 again. The reflected light can be blocked and absorbed by the light shielding layer 44, so that the reflected light will not be emitted from the first opening 21. Specifically, since the inclination degrees of the first side wall 51 and the second side wall 52 are set to be different in the present application, the direction of the light path of the light incident to the first electrode layer 43 on the surface of the first side wall 51 through the first opening 21 is not symmetrical to the direction of the light path of the emergent light reflected by the first electrode layer 43 on the surface of the first side wall 51 to the first electrode layer 43 on the surface of the second side wall 52 again. Therefore, the emergent light can not be emitted from the first opening 21, but can be emitted to the surface of the light shielding layer 44 and be absorbed. In this way, the amount of light emitted from the first opening 21 after secondary reflection can be reduced, which is beneficial to reduce the reflectivity of the panel.

[0080] Figure 3 Another cross-sectional view of the AA' plane provided by the embodiment of the present application is shown. Figure 10 Another cross-sectional view of the AA' plane provided by the embodiment of the present application is shown. Figure 3 Another cross-sectional view of the AA' plane provided by the embodiment of the present application is shown. Figure 1 Another cross-sectional view of the AA' plane provided by the embodiment of the present application is shown. Figure 3 、 Figure 9 、 Figure 10 、 Figure 10 Optionally, at least the side surface of the first electrode layer 43 away from the substrate 41 includes a curved surface at the position corresponding to the second opening 22.

[0081] Specifically, the application also provides an alternative arrangement mode, the first electrode layer 43 at the position corresponding to the second opening 22 includes a curved surface away from the side surface of the substrate 41, and the first electrode layer 43 with the curved surface structure realizes specific reflection of the light rays incident through the first opening 21, so that the incident light can be reflected in a specific direction through the specific curved surface, realizing customized directional reflection of ambient light, thereby reducing the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, weakening the influence of the reflected light on the display effect of the display panel 100, thereby facilitating improvement of the display uniformity of the display panel 100, and further improving the user experience.

[0082] It should be noted that the application does not limit the number of curved surfaces included in the first electrode layer 43 at the position corresponding to the second opening 22, for example, one second opening 22 can be provided with one curved surface, two curved surfaces, or even more curved surfaces, and the application does not specifically limit the number of curved surfaces provided at the second opening 22, and the user can make corresponding selection according to the needs. And the application does not limit the bending degree of the curved surface and the protruding direction of the curved surface. Any curved surface can be convex in the direction of the side of the substrate 41 (as shown in FIG. 4a) or convex in the direction of the side of the light shielding layer 44 (as shown in FIG. 4b). That is, the curved surface of the first electrode layer 43 provided at the position corresponding to the second opening 22 can be a convex curved surface, a concave curved surface, or both a convex curved surface and a concave curved surface (concave-convex curved surface), and the application does not specifically limit this. Figure 9 Figure 11

[0083] Figure 1 Figure 12 Figure 11 Figure 13 Figure 11 Figure 14 Figure 11 Figure 1 Figure 3 Figures 11-14 Figure 11 Optionally, the hole combination 20 further includes a second insulating layer 46, and the second insulating layer 46 is located on the side of the first insulating layer 42 close to the substrate 41.

[0084] The hole combination 20 further includes a third opening 23, the second opening 22 penetrates the first insulating layer 42, and the third opening 23 penetrates at least part of the second insulating layer 46; the second opening 22 and the third opening 23 are communicated.

[0085] ​​​​​​​​​​​​The aperture of the second opening 22 and the aperture of the third opening 23 are different, and at least one side wall of the second opening 22 and at least one side wall of the third opening 23 are continuous.

[0086] Specifically, the application provides an alternative embodiment that the display panel 100 includes two insulating layers, such as including the first insulating layer 42 in the display panel 100, and further including the second insulating layer 46, where the second insulating layer 46 is arranged on the side of the first insulating layer 42 close to the substrate 41. On the basis of this structure, the application can further provide that the hole combination 20 includes the third opening 23 in addition to the first opening 21 and the second opening 22, and at this time, the second opening 22 is arranged to penetrate the first insulating layer 42, and the third opening 23 is arranged to penetrate the entire second insulating layer 46 (as shown in FIG. 2B). Figures 12-14 Or the third opening 23 is arranged to remove part of the second insulating layer 46 from the surface of the second insulating layer 46 away from the substrate 41 to the side of the substrate 41 (as shown in FIG. 2C), and the second opening 22 and the third opening 23 are in communication. Figure 4

[0087] At this time, the first electrode layer 43 can be formed inside the second opening 22 and the third opening 23 towards the opening, that is, as shown in FIG. 2B, or as shown in FIG. 2C. Figures 12-14 The embodiment shown is proposed for the display panel 100 including two adjacent insulating layers (the first insulating layer 42 and the second insulating layer 46), compared with the previous embodiment including only one insulating layer (the first insulating layer 42), the setting of the non-planar first electrode layer 43 in the entire insulating layer (the first insulating layer 42 and the second insulating layer 46) is realized, and the asymmetric design of the first opening 21 and the opening in the insulating layer (the second opening 22 and the third opening 23) can be realized. Specifically, the first electrode layer 43 formed here can have multiple inclined surfaces relative to the plane where the substrate 41 is located, and the first electrode layer 43 with the inclined surfaces can realize specific reflection of the incident light through the first opening 21, like the principle shown in the previous Figure 5 The principle diagram is the same as the previous one, and the first electrode layer 43 with the non-planar structure can reflect more incident light to the surface of the light shielding layer 44 close to the substrate 41 and be absorbed by the light shielding layer 44, thereby reducing the number of reflected light that is incident to the first electrode layer 43 and then emitted from the first opening 21, that is, by setting the first electrode layer 43 with the non-planar structure, part of the light can be reflected to the light shielding layer 44 and absorbed by it; in addition, Figure 12 The hole combination 20 shown in the above can also be asymmetrically designed, like the previous Figure 13 ​The principle shown is the same as the principle shown in the schematic diagram. The part of the light that would be reflected by the first electrode layer (multiple times) and then emitted from the first opening 21 can be adjusted to be reflected by the first electrode layer 43 to the side surface of the light shielding layer 44 close to the substrate 41, and be absorbed by the light shielding layer 44. That is, the incident light can be reflected in a specific direction by the first electrode layer 43 of the non-planar structure and / or the asymmetrically designed hole group 20, so as to realize customized directional reflection of ambient light, thereby reducing the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, weakening the influence of the reflected light on the display effect of the display panel 100, thereby improving the display uniformity of the display panel 100, and further improving the user experience.

[0088] Furthermore, the present application can also provide an alternative embodiment, in which the aperture of the second opening 22 and the aperture of the third opening 23 are different. For example, when the orthographic projection of the second opening 22 on the plane where the substrate 41 is located and the orthographic projection of the third opening 23 on the plane where the substrate 41 is located are circular, the diameter of the second opening 22 and the diameter of the third opening 23 are different. At the same time, at least part of the side wall of the second opening 22 and part of the side wall of the third opening 23 can be smoothly connected (as shown in Figure 14 、 Figure 2 ), and there can be no connection between part of the side wall of the second opening 22 and part of the side wall of the third opening 23 (as shown in Figures 12-14 ). Such a design can increase the area of the side wall, so that more light rays incident through the first opening 21 can be irradiated onto the side surface. Therefore, more light rays can be reflected by the first electrode layer 43 at the side surface position in a specific direction, so as to reflect more incident light rays to the light shielding layer 44 and be absorbed by the light shielding layer 44, thereby reducing the number of reflected light rays emitted from the first opening 21. That is, the customized directional reflection of ambient light can be realized, the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43 can be reduced, the influence of the reflected light on the display effect of the display panel 100 can be weakened, and the display uniformity of the display panel 100 can be improved.

[0089] It should be noted that, please refer to Figure 2 , the first insulating layer 42 and the second insulating layer 46 shown in the present application Figure 14 are equivalent to the first sub-insulating layer 424 and the second sub-insulating layer 423 in Figure 1 .

[0090] It should also be noted that, as Figure 3As shown, when the diameters of the second opening 22 and the third opening 23 are different, if the side walls (such as the second side wall 52 and the fourth side wall 54) of the second opening 22 and the third opening 23 are ensured to be continuous smooth surfaces during the manufacturing process, the surfaces on the opposite side of the smooth surfaces will be stepped surfaces, and the angles of the stepped surfaces corresponding to the side walls of the second opening 22 and the third opening 23 towards the inside of the insulating layer will be different from the angles of the side walls corresponding to the smooth surfaces towards the inside of the insulating layer; that is, the two side walls (one side wall is the second side wall 52 and the fourth side wall 54, and one side wall is the first side wall 51 and the third side wall 53) formed by the second opening 22 and the third opening 23 have different inclination degrees. As described above, the inclination degree of the second side wall 52 and the fourth side wall 54 is different from the inclination degree of the first side wall 51 and the third side wall 53 on the opposite side of the opening, the direction of the light path of the first electrode layer 43 on the surface of the first side wall 51 and / or the third side wall 53 incident from the first opening 21 is asymmetric to the direction of the light path of the emergent light reflected to the first electrode layer 43 on the surface of the second side wall 52 and / or the fourth side wall 54 again, so that the emergent light can not be emitted from the first opening 21, but emitted to the surface of the light shielding layer 44 and absorbed, thereby reducing the amount of light emitted from the first opening 21 after secondary reflection, which is beneficial to reduce the reflectivity of the panel.

[0091] Please refer to Figure 14 、 Figure 4 、 Figure 14 Optionally, the second opening 22 includes the first side wall 51 and the second side wall 52, and the third opening 23 includes the third side wall 53 and the fourth side wall 54, the orthographic projection of the fourth side wall 54 on the plane where the substrate 41 is located and the orthographic projection of the second side wall 52 on the plane where the substrate 41 is located at least partially overlap; the orthographic projection of the third side wall 53 on the plane where the substrate 41 is located is located within the orthographic projection of the second opening 22 on the plane where the substrate 41 is located.

[0092] Specifically, the application also provides an alternative arrangement mode, the display panel 100 includes a first insulating layer 42 and a second insulating layer 46, the display panel 100 includes a second opening 22 and a third opening 23 arranged correspondingly, the second opening 22 is formed through the first insulating layer 42, the third opening 23 is formed through the entire second insulating layer 46, or the third opening 23 is formed by removing part of the second insulating layer 46 from the surface of the second insulating layer 46 away from the substrate 41 to the substrate 41 side, and the second opening 22 and the third opening 23 are communicated. If the second opening 22 includes a first side wall 51 and a second side wall 52, the third opening 23 can include a corresponding third side wall 53 and a fourth side wall 54, at this time, the orthogonal projection of the fourth side wall 54 on the plane where the substrate 41 is located and the orthogonal projection of the second side wall 52 on the plane where the substrate 41 is located at least partially overlap, and the orthogonal projection of the third side wall 53 on the plane where the substrate 41 is located is located within the orthogonal projection of the second opening 22 on the plane where the substrate 41 is located; it is equivalent to arranging the second side wall 52 and the fourth side wall 54, the second opening 22 is larger than the third opening 23 to the inside space of the hole away from the hole.

[0093] The first electrode layer 43 formed by the above-mentioned structure of the second opening 22 and the third opening 23 towards the inside of the opening, relative to the plane where the substrate 41 is located, can have an inclined surface, by the first electrode layer 43 with a larger area of the inclined surface, the specific reflection of the light rays incident through the first opening 21 is realized, part of the light rays are reflected to the light shielding layer 44 and absorbed by it, so that the incident light can be reflected in a specific direction by the first electrode layer 43 with a specific structure, realizing the customized direction of the reflection of the ambient light, so as to reduce the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, weakening the influence of the reflected light on the display effect of the display panel 100, thereby improving the display uniformity of the display panel 100, and further improving the user experience.

[0094] In addition, the application sets the second opening 22 and the third opening 23 to be communicated, which can realize the non-planar structure of the first electrode layer 43 at this position, as Figure 14 The principle shown is the same, compared with the first electrode layer with a pure planar structure, the first electrode layer 43 with a non-planar structure can reflect more incident light to the surface of the light shielding layer 44 close to the substrate 41, and be absorbed by the light shielding layer 44, thereby reducing the number of reflected light emitted from the first opening 21 after being incident to the first electrode layer 43. Furthermore, the orthogonal projection of the third side wall 43 on the plane where the substrate 41 is located is located within the orthogonal projection of the second opening 22 on the plane where the substrate 41 is located, which is equivalent to arranging the first side wall 51 and the third side wall 53 to be non-smoothly connected, that is, as Figure 14 Figure 1 ​The incident light ray 96 shown in FIG. 1A is reflected to the first electrode layer 43 on the surface of the second side wall 52 after being emitted to the first electrode layer 43 on the surface of the second side wall 52, and then is reflected to the light shielding layer 44 for the second time and is absorbed by the light shielding layer 44. If the third side wall is arranged along the extension direction of the first side wall, as shown in FIG. 1B, the incident light ray 96 is reflected to the first electrode layer 43 on the surface of the first side wall after being emitted to the first electrode layer 43 on the surface of the second side wall, and then is reflected to the first opening 21 by the first electrode layer 43. Obviously, by arranging the third side wall 53 not along the extension direction of the first side wall 51, part of the incident light ray can be reflected to the surface of the light shielding layer 44 and absorbed, instead of being reflected to the first opening 21 for emission, so that the number of light rays reflected by the first electrode layer 43 and emitted from the first opening 21 can be reduced, and the influence of the reflected light rays on the display effect of the display panel 100 can be weakened. Figure 3 The incident light ray 96 shown in FIG. 1A is reflected to the first electrode layer 43 on the surface of the second side wall 52 after being emitted to the first electrode layer 43 on the surface of the second side wall 52, and then is reflected to the light shielding layer 44 for the second time and is absorbed by the light shielding layer 44. If the third side wall is arranged along the extension direction of the first side wall, as shown in FIG. 1B, the incident light ray 96 is reflected to the first electrode layer 43 on the surface of the first side wall after being emitted to the first electrode layer 43 on the surface of the second side wall, and then is reflected to the first opening 21 by the first electrode layer 43. Obviously, by arranging the third side wall 53 not along the extension direction of the first side wall 51, part of the incident light ray can be reflected to the surface of the light shielding layer 44 and absorbed, instead of being reflected to the first opening 21 for emission, so that the number of light rays reflected by the first electrode layer 43 and emitted from the first opening 21 can be reduced, and the influence of the reflected light rays on the display effect of the display panel 100 can be weakened.

[0095] Please continue to refer to Figure 14 、 Figure 14 、 Figure 14 Optionally, the first side wall 51 and the bottom surface of the first insulating layer 42 form a first included angle a1, the third side wall 53 and the bottom surface of the second insulating layer 46 form a third included angle a3, the first included angle a1 and the third included angle a3 are both acute angles, and the first included angle a1 and the third included angle a3 are different in size.

[0096] Specifically, the application also provides an alternative arrangement, that is, the display panel 100 includes the first insulating layer 42 and the second insulating layer 46, the display panel 100 includes the second opening 22 and the third opening 23 arranged correspondingly, the second opening 22 penetrates through the first insulating layer 42, the third opening 23 penetrates through the entire second insulating layer 46, or the third opening 23 is formed by removing part of the second insulating layer 46 from the surface of the second insulating layer 46 away from the substrate 41 to the substrate 41 side, and the second opening 22 and the third opening 23 are communicated. If the second opening 22 includes the first side wall 51 and the second side wall 52, the third opening 23 can include the corresponding third side wall 53 and the fourth side wall 54. The plane where the first side wall 51 is located and the bottom surface of the first insulating layer 42 form a first included angle a1, and the plane where the third side wall 53 is located and the bottom surface of the second insulating layer 46 form a third included angle a3. The application can be arranged such that the first included angle a1 and the third included angle a3 are both acute angles, in which case the first included angle a1 and the third included angle a3 can be the same in size, or the first included angle a1 and the third included angle a3 can be different in size, and the application does not make a specific limitation in this regard.

[0097] The first electrode layer 43 formed inside the second opening 22 and the third opening 23 of the above-mentioned structure can have an inclined surface relative to the plane of the substrate 41. The first electrode layer 43 with a larger inclined surface can achieve specific reflection of the light incident through the first opening 21, reflecting part of the light to the light-shielding layer 44 and being absorbed by it. Thus, the incident light can be reflected in a specific direction by the first electrode layer 43 with a specific structure, realizing customized reflection of ambient light. This can reduce the amount of light emitted from the first opening 21 after being reflected by the first electrode layer 43, weaken the impact of reflected light on the display effect of the display panel 100, thereby improving the display uniformity of the display panel 100 and enhancing the user experience.

[0098] Furthermore, if the first included angle α1 and the third included angle α3 are set to be the same size, such as Figure 14 As shown, the incident light 96, after exiting the first electrode layer on the second sidewall surface, is reflected to the first electrode layer on the extended surface of the third sidewall, and then reflected by the first electrode layer to exit through the first opening; however, in this application, when the first included angle α1 is set to be smaller than the third included angle α3, such as Figure 15 As shown, the incident light 96, after exiting the first electrode layer 43 on the surface of the second sidewall 52, is reflected back to the first electrode layer 43 on the surface of the third sidewall 53, and then reflected a second time to the light-shielding layer 44 where it is absorbed. Clearly, by setting the extension directions of the third sidewall 53 and the first sidewall 51 to be different, i.e., by setting the first included angle α1 and the third included angle α3 to be different, this application enables some of the incident light to be reflected back to the surface of the light-shielding layer 44 and absorbed, rather than being reflected back to the first opening 21 for exit. This reduces the amount of light emitted from the first opening 21 after being reflected by the first electrode layer 43, thus weakening the impact of reflected light on the display effect of the display panel 100.

[0099] Furthermore, the first sidewall 51 and the third sidewall 53 are presented as Figure 1 When the stepped configuration is shown, the corresponding second sidewall 52 and fourth sidewall 54 can also be configured as the same stepped configuration as the first sidewall 51 and third sidewall 53; the manufacturing of the stepped second opening 22 and third opening 23 is easier to achieve in terms of process, which helps to reduce the process difficulty of forming the non-planar first electrode layer 43.

[0100] Figure 16 The image shown is of this application. Figure 15 Another perspective view of the hole assembly provided in the image. Figure 1 The image shown is provided in an embodiment of this application. Figure 15 Please refer to a cross-sectional view of DD'. Figure 16 , Figures 12-14 and Figure 16 In addition to the above Figure 16In addition to the provided configuration of the second opening 22 and the third opening 23, the second opening 22 and the third opening 23 can also be configured as follows: Figure 16 The illustrated embodiment is configured as follows; wherein, Figure 16 In the illustrated embodiment, the apertures of the first opening 21, the second opening 22, and the third opening 33 are the same. For example, when the orthographic projections of the first opening 21, the second opening 22, and the third opening 33 onto the plane of the substrate 41 are all circular, then the diameters of the orthographic projections of the first opening 21, the second opening 22, and the third opening 33 onto the plane of the substrate 41 are all the same. In this case, when the hole combination 20 is designed asymmetrically, specifically, the first opening 21, the second opening 22, and the third opening 33 can be staggered. Figure 16 As shown, viewed from the perspective of the accompanying drawing of this application, the center point of the second opening 22 is located to the right of the center point of the first opening 21, and the center point of the third opening 33 is located to the right of the center point of the second opening 22. With this arrangement, the first electrode layer 43, a non-planar structure formed by the surfaces of the first sidewall 51, the second sidewall 52, the third sidewall 53, the fourth sidewall 54, and the bottom surface between the third sidewall 53 and the fourth sidewall 54, can reflect certain incident light rays multiple times. After multiple reflections, the light intensity weakens. Even if the reflected light ultimately exits through the first opening 21, the impact of the reflected light on the display panel 100 can be reduced to some extent. Furthermore, the light after multiple reflections may also be reflected to the surface of the light-shielding layer 44 and absorbed, thereby reducing the amount of light emanating from the first opening 21, which helps to reduce the impact of reflected light on the display panel 100. In other words, compared to the incident light being reflected by the first electrode layer and then directly exiting through the first opening, the first electrode layer 43 can reflect certain incident light rays multiple times. Figure 14 The illustrated embodiment is beneficial for reducing the amount of reflected light emitted again from the first opening 21 and can reduce the light intensity of some of the reflected light emitted again from the first opening 21, thereby achieving the technical effect of reducing the reflectivity of the display panel 100.

[0101] In addition, such as Figure 17 In the embodiment shown, the third opening 23 is formed by the second insulating layer 46. However, during the further fabrication of the first insulating layer 42, the first insulating layer 42 fills part of the third opening 23, that is, the sidewalls of the continuous opening 22 and the third opening 33 are formed such that one side (the first sidewall 51 and the third sidewall 53) is formed by the first insulating layer 42 and the second insulating layer 46, and the other side (the second sidewall 52 and the fourth sidewall 54) is formed by the first insulating layer 42. This makes the final third opening and the second opening 22 unequal in size, thus achieving the same effect as described above. Figure 1The shown embodiment has the same technical effect, that is, the two side walls formed by the second opening 22 and the third opening 23 (one side wall is the second side wall 52 and the fourth side wall 54, and one side wall is the first side wall 51 and the third side wall 53) have different inclination degrees. As described above, the inclination degree of the second side wall 52 and the fourth side wall 54 is different from that of the first side wall 51 and the third side wall 53 on the opposite side of the opening. The light path direction of the light incident to the first electrode layer 43 on the surface of the first side wall 51 and / or the third side wall 53 through the first opening 21 is asymmetric to the light path direction of the emergent light reflected to the second side wall 52 and / or the fourth side wall 54 after being reflected by the first electrode layer 43 on the surface of the first side wall 51 and / or the third side wall 53. Therefore, the emergent light can not be emitted from the first opening 21, but is emitted to the surface of the light shielding layer 44 and is absorbed. In this way, the amount of light emitted from the first opening 21 after secondary reflection can be reduced, which is beneficial to reduce the reflectivity of the display panel.

[0102] It should be noted that when the third opening 23 is formed in the second insulating layer 46, and when the second opening 22 is formed in the first insulating layer 42, the aperture of the third opening 23 and the aperture of the second opening 22 can be the same. In this way, the smooth transition of a side wall can be avoided.

[0103] Furthermore, in the embodiments provided by the present application, the second opening 22 and the third opening 23 are arranged in a staggered manner to achieve the desired technical effect, which avoids the problem of alignment of the second opening 22 and the third opening 23 in the process, and to some extent, simplifies the process difficulty of the second opening 22 and the third opening 23, which is beneficial to improve the manufacturing efficiency of the display panel 100.

[0104] Figure 18 Fig. 4 shows another perspective view of the hole combination provided by the present application, Figure 17 Fig. 5 shows a cross-sectional view of the CC' in the hole combination provided by the embodiments of the present application, please refer to Figure 1 Fig. 6 shows another cross-sectional view of the CC' in the hole combination provided by the embodiments of the present application, please refer to Figure 3 Fig. 7 shows another cross-sectional view of the CC' in the hole combination provided by the embodiments of the present application, please refer to Figures 14-18 Fig. 8 shows another cross-sectional view of the CC' in the hole combination provided by the embodiments of the present application, please refer to Figure 18 Fig. 9 shows another cross-sectional view of the CC' in the hole combination provided by the embodiments of the present application, please refer to Figures 11-18 Optionally, the hole combination 20 further comprises a second insulating layer 46, and the second insulating layer 46 is located on the side of the first insulating layer 42 close to the substrate 41;

[0105] The hole combination 20 further comprises a third opening 23, the second opening 22 penetrates the first insulating layer 42, and the third opening 23 penetrates at least part of the second insulating layer 46; the second opening 22 and the third opening 23 are in communication;

[0106] The aperture of the second opening 22 and the aperture of the third opening 23 are different;

[0107] At least a portion of the sidewalls of the second opening 22 and at least a portion of the sidewalls of the third opening 23 have different degrees of inclination relative to the substrate 41.

[0108] Specifically, this application provides an alternative embodiment in which the display panel 100 includes two insulating layers. For example, in addition to the first insulating layer 42, the display panel 100 may further include a second insulating layer 46. Here, the second insulating layer 46 may be located on the side of the first insulating layer 42 that is close to the substrate 41. Based on this structure, this application may further provide a hole combination 20 that includes a third opening 23 in addition to the first opening 21 and the second opening 22. In this case, the second opening 22 is formed by penetrating the first insulating layer 42, and the third opening 23 is formed by penetrating the entire second insulating layer 46. Alternatively, the third opening 23 may be formed by removing part of the second insulating layer 46 from the surface of the second insulating layer 46 facing away from the substrate 41 and towards the substrate 41, so that the second opening 22 and the third opening 23 are connected.

[0109] At this point, the second opening 22 and the third opening 23 can be configured to have different apertures. For example, when the orthographic projections of the second opening 22 and the third opening 23 onto the plane of the substrate 41 are both circular, the radii of the second opening 22 and the third opening 23 can be set to be different. In this case, it is not restricted whether there are intersecting sidewalls between the second opening 22 and the third opening 23. At this point, the sidewall of the second opening 22 can be configured to have a different degree of inclination than the sidewall of the third opening 23. That is, the angle between the plane containing a portion of the sidewall of the second opening 22 and the plane of the substrate 41, and the angle between the plane containing the corresponding portion of the sidewall of the third opening 23 and the plane of the substrate 41 are different (e.g., ...). Figure 14 (The sizes of α1 and α3 are different, and the sizes of α2 and α4 are different, as shown); of course, it is also possible to choose to set the included angle to be the same. In this structure, the first electrode layer 43 formed inside the second opening 22 and the third opening 23 can have an inclined surface relative to the plane of the substrate 41. The first electrode layer 43 with a larger inclined surface can achieve specific reflection of the light incident through the first opening 21, reflecting part of the light to the light-shielding layer 44 and being absorbed by it. Thus, the incident light can be reflected in a specific direction through the first electrode layer 43 with a specific structure, realizing customized reflection of ambient light. This can reduce the amount of light emitted from the first opening 21 after being reflected by the first electrode layer 43, weaken the impact of reflected light on the display effect of the display panel 100, thereby improving the display uniformity of the display panel 100 and enhancing the user experience.

[0110] In addition, the first electrode layer 43 of the non-planar structure in the present application has a surface with multiple different inclinations and different inclination directions, so that more light rays incident through the first opening 21 can be reflected once or multiple times by the first electrode layer 43 of the non-planar structure. As described above, the first electrode layer 43 of the non-planar structure can cause part of the incident light rays to be finally reflected to the light shielding layer 44 and absorbed thereby, or can cause part of the light rays to be weakened after multiple reflections, which are all conducive to reducing the reflectivity of the display panel 100 and improving the display effect of the display panel 100.

[0111] Please refer to Figure 19 Optionally, the display panel 100 further comprises a second insulating layer 46, and the second insulating layer 46 is located on the side of the first insulating layer 42 close to the substrate 41.

[0112] The hole combination 20 further comprises a third opening 23, the second opening 22 penetrates the first insulating layer 42, and the third opening 23 penetrates at least part of the second insulating layer 46; the second opening 22 and the third opening 23 are in communication.

[0113] The third opening 23 is located in the projection of the second opening 22 on the plane of the substrate 41.

[0114] Specifically, the present application provides an alternative embodiment that the display panel 100 comprises two insulating layers, for example, the display panel 100 comprises the first insulating layer 42, and further comprises the second insulating layer 46, and the second insulating layer 46 is located on the side of the first insulating layer 42 close to the substrate 41. On the basis of this structure, the present application can further provide that the hole combination 20 comprises the third opening 23 in addition to the first opening 21 and the second opening 22, and at this time, the second opening 22 is formed by penetrating the first insulating layer 42, the third opening 23 is formed by penetrating the entire second insulating layer 46, or the third opening 23 is formed by removing part of the second insulating layer 46 from the surface of the second insulating layer 46 away from the substrate 41 to the side of the substrate 41, and the second opening 22 and the third opening 23 are in communication.

[0115] At this time, the aperture of the third opening 23 can be smaller than the aperture of the second opening 22, and the third opening 23 is located in the projection of the second opening 22 on the plane of the substrate 41, which is equivalent to that the first electrode layer 43 formed by the second opening 22 and the third opening 23 towards the inside of the opening forms a step form, and the first electrode layer 43 can have an inclined surface relative to the plane of the substrate 41. Similarly, the first electrode layer 43 with a larger area of the inclined surface can achieve specific reflection of the light rays incident through the first opening 21, and part of the light rays can be reflected to the light shielding layer 44 and absorbed thereby. In addition, as Figure 3The principle is shown, and the application can make part of the incident light be reflected to the surface of the light shielding layer 44 and be absorbed, instead of being reflected to the first opening 21 and being emitted, by setting the third side wall 53 not in the extension direction of the first side wall 51, so as to reduce the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, and weaken the influence of the reflected light rays on the display effect of the display panel 100. That is, the application makes the incident light be reflected in a specific direction by the first electrode layer 43 with a specific structure, so as to realize the customized direction of reflection of ambient light, thereby reducing the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, weakening the influence of the reflected light rays on the display effect of the display panel 100, thereby being beneficial to improving the display uniformity of the display panel 100, and further improving the user experience.

[0116] Figure 1 The application provides another cross-sectional view of the AA' in the embodiment Figure 3 The application provides another cross-sectional view of the AA' in the embodiment Figure 19 , Figure 20 , Figure 3 Optionally, the display panel 100 further comprises a flat layer 47, and the flat layer 47 is located between the first insulating layer 42 and the substrate 41.

[0117] The second opening 22 exposes the flat layer 47.

[0118] Specifically, the application provides an alternative setting mode, on the basis of the display panel 100 comprising the substrate 41, the first insulating layer 42, the first electrode layer 43 and the light shielding layer 44, the display panel 100 can further comprise the flat layer 47, and the flat layer 47 can be arranged between the first insulating layer 42 and the substrate 41. The application provides an alternative setting mode, that is, the second opening 22 penetrates through the entire first insulating layer 42 and exposes the surface of the flat layer 47 away from the substrate 41. In this way, the formation of the second opening 22 can be realized only by etching or other operations on the first insulating layer 42, or the position of the second opening 22 can be left out when the first insulating layer 42 is prepared, which is relatively simple in process manufacturing.

[0119] The application does not make specific limitation on the shape of the second opening 22 formed through the whole first insulating layer 42. For example, the second opening 22 can include an inclined surface, can include a curved surface, etc. By forming the first electrode layer 43 on the side of the inclined surface / curved surface included in the second opening 22 towards the inside of the hole, the first electrode layer 43 here will include the corresponding inclined surface / curved surface. By having the first electrode layer 43 with the inclined surface / surface, the incident light through the first opening 21 is reflected in a specific direction, and part of the light is reflected to the light shielding layer 44 and absorbed by the light shielding layer 44. Thus, the incident light can be reflected in a specific direction by the first electrode layer 43 with a specific structure, realizing customized directional reflection of ambient light, thereby reducing the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, weakening the influence of the reflected light on the display effect of the display panel 100, thereby facilitating the improvement of the display uniformity of the display panel 100, and further improving the user experience.

[0120] Figure 1 Another cross-sectional view of AA' provided by the embodiment of the application is shown. Please refer to Figure 3 Figure 20 Figure 21 Figure 3 Optionally, the display panel 100 further includes a flat layer 47, and the flat layer 47 is located between the first insulating layer 42 and the substrate 41.

[0121] The second opening 22 penetrates the first insulating layer 42 and is located at least partially in the flat layer 47.

[0122] Specifically, the application provides an alternative arrangement. On the basis of the display panel 100 including the substrate 41, the first insulating layer 42, the first electrode layer 43, and the light shielding layer 44, the display panel 100 can further include the flat layer 47, which can be arranged between the first insulating layer 42 and the substrate 41. The application provides an alternative arrangement, in which the second opening 22 penetrates the whole first insulating layer 42, and further removes part of the flat layer 47 / entire flat layer 47 away from the side surface of the flat layer 47 away from the substrate 41 to form another part of the second opening 22 towards the substrate 41.

[0123] ​​​By forming the second opening 22 through at least part of the first insulating layer 42 or the first insulating layer 42 plus the planar layer 47, the present application does not make specific limitations on the shape of the second opening 22 at this position, for example, the second opening 22 can include an inclined surface, can include a curved surface, etc. By forming the first electrode layer 43 on the side of the interior of the hole through the inclined surface / curved surface included in the second opening 22, the first electrode layer 43 here will include a corresponding inclined surface / curved surface. By having the first electrode layer 43 with an inclined surface / slope, the specific reflection of the light rays incident through the first opening 21 is realized, and part of the light rays are reflected to the light shielding layer 44 and absorbed by it, so that the incident light can be reflected in a specific direction by the first electrode layer 43 with a specific structure, realizing the customized directional reflection of ambient light, thereby being able to reduce the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, weakening the influence of the reflected light on the display effect of the display panel 100, thereby being beneficial to improve the display uniformity of the display panel 100, and further improving the user experience.

[0124] In addition, the present application further penetrates at least part of the planar layer 47 to form the second opening 22 after penetrating through the first insulating layer 42. In this structure, the first electrode layer 43 with a non-planar structure at the second opening 22 has a larger surface area than that formed by only penetrating the first insulating layer 22 at the second opening 22, and the area of the inclined surface is also relatively large. By the first electrode layer 43 with a non-planar structure with a large area, a larger number of incident light rays can be reflected in a specific direction, or multiple reflections of incident light rays, so as to reduce the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, or weaken the illumination intensity of the light rays emitted from the first opening 21 after being reflected multiple times by the first electrode layer 43, which is beneficial to reduce the reflectivity of the display panel 100.

[0125] Figure 1 It is shown that the present application provides Figure 3 another cross-sectional view of the AA' in the embodiment of the present application, please refer to Figure 21 、 Figure 22 、 Figure 17 Optionally, the display panel 100 further comprises a planar layer 47, and the planar layer 47 is located between the first insulating layer 42 and the substrate 41.

[0126] The planar layer 47 comprises a first planar layer 471 and a second planar layer 472, and the first planar layer 471 is located between the second planar layer 472 and the substrate 41.

[0127] The second opening 22 penetrates through the first insulating layer 42 and the second planar layer 472.

[0128] Specifically, the application provides a selectable setting mode, on the basis of the display panel 100 comprising a substrate 41, a first insulating layer 42, a first electrode layer 43, and a light shielding layer 44, the display panel 100 further comprises a planar layer 47, which is arranged between the first insulating layer 42 and the substrate 41. The application provides a selectable setting mode, the planar layer 47 comprises a first planar layer 471 and a second planar layer 472, and the first planar layer 471 is located between the second planar layer 472 and the substrate 41. At this time, on the basis of the second opening 22 penetrating through the entire first insulating layer 42, a part of the first planar layer 471 / the entire first planar layer 471 is further removed from the side surface of the second planar layer 472 away from the substrate 41 to form another part of the second opening 22.

[0129] The second opening 22 is formed by the first insulating layer 42 and the second planar layer 472, compared with forming the second opening 22 in the first insulating layer 42 only, the surface area of the first electrode layer 43 with a non-planar structure at the second opening 22 is increased, and the area of the inclined surface is also relatively increased. Through the first electrode layer 43 with a non-planar structure with a large area, more number of incident light rays can be reflected in a specific direction or multiple reflected, so as to reduce the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, or weaken the illumination intensity of the light rays emitted from the first opening 21 after being multiple reflected by the first electrode layer 43, which is beneficial to reduce the reflectivity of the display panel 100. In addition, the shape of the second opening 22 is not specifically limited in the application, for example, the second opening 22 can comprise an inclined surface and a curved surface. The first electrode layer 43 is formed on the side of the inclined surface / curved surface of the second opening 22, and the first electrode layer 43 comprises a corresponding inclined surface / curved surface. The first electrode layer 43 with an inclined surface / surface realizes specific reflection of the incident light rays through the first opening 21, reflects part of the light rays to the light shielding layer 44 and absorbs them, so that the incident light is reflected in a specific direction through the first electrode layer 43 with a specific structure, realizing customized directional reflection of ambient light, thereby reducing the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, weakening the influence of the reflected light on the display effect of the display panel 100, thereby improving the display uniformity of the display panel 100 and further improving the user experience.

[0131] The hole group 20 further comprises a third opening hole 23, the third opening hole 23 penetrating through the at least partially flat layer 47;

[0132] The second opening hole 22 comprises a first sidewall 51 and a second sidewall 52, the third opening hole 23 comprises a third sidewall 53 and a fourth sidewall 54, the fourth sidewall 54 in the orthographic projection on the plane where the substrate 41 is located and the second sidewall 52 in the orthographic projection on the plane where the substrate 41 is located at least partially overlap; the third sidewall 53 in the orthographic projection on the plane where the substrate 41 is located is located within the orthographic projection on the plane where the substrate 41 is located of the second opening hole 22.

[0133] Specifically, the present application provides an alternative setting mode, on the basis of the display panel 100 comprising the substrate 41, the first insulating layer 42, the first electrode layer 43, the light shielding layer 44, further comprising the flat layer 47, which can be arranged between the first insulating layer 42 and the substrate 41, at this time, the present application can be arranged on the basis of the display panel 100 comprising the first opening hole 21 and the second opening hole 22, further arranging the third opening hole 23 in the flat layer 47, here the third opening hole 23 can be formed by digging part of the flat layer 47 / all of the flat layer 47 away from the side surface of the flat layer 47 to the side of the substrate 41; and making the second opening hole 22 and the third opening hole 23 communicate.

[0134] At this time, the second opening hole 22 can comprise the first sidewall 51 and the second sidewall 52, the corresponding position of the third opening hole 23 can comprise the third sidewall 53 and the fourth sidewall 54, at this time, the fourth sidewall 54 in the orthographic projection on the plane where the substrate 41 is located and the second sidewall 52 in the orthographic projection on the plane where the substrate 41 is located at least partially overlap, and the third sidewall 53 in the orthographic projection on the plane where the substrate 41 is located is located within the orthographic projection on the plane where the substrate 41 is located of the second opening hole 22; it is equivalent to setting the second sidewall 52, the fourth sidewall 54 on this side, the second opening hole 22 is larger than the third opening hole 23 towards the hole space on the side away from the inside of the hole.

[0135] The above-mentioned structure of the second opening hole 22 and the third opening hole 23 towards the inside of the hole formed by the first electrode layer 43, relative to the plane where the substrate 41 is located, can exist an inclined surface, by having a larger area of the inclined surface of the first electrode layer 43, realizing the specific reflection of the light rays incident through the first opening hole 21, reflecting part of the light rays to the light shielding layer 44 and being absorbed by it; in addition, as Figure 17The principle is shown, and the application can make part of the incident light be reflected to the surface of the light shielding layer 44 and be absorbed, instead of being reflected to the first opening 21 to be emitted, by setting the third side wall 53 not in the extension direction of the first side wall 51, thereby reducing the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43; that is, the application makes the incident light be reflected in a specific direction by the first electrode layer 43 with a specific structure, thereby realizing customized directional reflection of ambient light, reducing the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, weakening the influence of reflected light on the display effect of the display panel 100, thereby facilitating to improve the display uniformity of the display panel 100, and further improving the user experience.

[0136] Figure 1 Another cross-sectional view of the CC' provided by the embodiment of the application is shown, please refer to Figure 17 , Figure 23 , Figure 1 , Figure 3 , on the basis of the structure provided, optionally, the first side wall 51 and the bottom surface of the first insulating layer 42 form a first included angle α1, the third side wall 53 and the bottom surface of the flat layer 47 form a third included angle α3, the first included angle α1 and the third included angle α3 are acute angles, and the third included angle α3 is equal to the first included angle α1. Specifically, the plane where the first side wall 51 is located and the bottom surface of the first insulating layer 42 form a first included angle α1, and the plane where the third side wall 53 is located and the plane where the bottom surface of the flat layer 47 is located form a third included angle α3, wherein the first included angle α1 and the third included angle α3 are acute angles, and the sizes of the first included angle α1 and the second included angle α2 can be optionally set to be the same; in addition, the sizes of the first included angle α1 and the second included angle α2 can also be set to be different, which is not limited in the application, as long as the first electrode layer 43 located inside the second opening 22 and the third opening 23 can perform specific reflection on the incident light through the first opening 21, and part of the light is reflected to the light shielding layer 44 and absorbed.

[0137] In general, the first electrode layer 43 with a non-planar structure provided by the application has surfaces with multiple different inclinations and different inclination directions, so that the light rays incident through the first opening 21 can be reflected by the first electrode layer 43 with a non-planar structure once or multiple times, as described above, the first electrode layer 43 with a non-planar structure can make part of the incident light be reflected to the light shielding layer 44 and be absorbed, or can make part of the light be reflected multiple times and the light intensity be weakened, which is all conducive to reducing the reflectivity of the display panel 100 and improving the display effect of the display panel 100.

[0138] Please refer to Figure 17 , Figure 22 , Figure 23 ,Figure 14 、 Figure 1 Optionally, the display panel 100 further comprises a flat layer 47, the flat layer 47 is located between the first insulating layer 42 and the substrate 41;

[0139] The hole group 20 further comprises a third opening hole 23, the third opening hole 23 penetrates through at least part of the flat layer 47;

[0140] The orthographic projection of the third opening hole 23 on the plane where the substrate 41 is located is located within the orthographic projection of the second opening hole 22 on the plane where the substrate 41 is located.

[0141] Specifically, the present application provides an alternative setting mode, on the basis of the display panel 100 comprising the substrate 41, the first insulating layer 42, the first electrode layer 43, and the light shielding layer 44, the display panel 100 can further comprise the flat layer 47, the flat layer 47 can be arranged between the first insulating layer 42 and the substrate 41, at this time, on the basis of the display panel 100 comprising the first opening hole 21 and the second opening hole 22, the third opening hole 23 can be further arranged in the flat layer 47, the third opening hole 23 can be formed by digging part of the flat layer 47 / all of the flat layer 47 from the side surface of the flat layer 47 away from the substrate 41 to the side of the substrate 41; and the second opening hole 22 and the third opening hole 23 are communicated.

[0142] At this time, the aperture of the third opening hole 23 can be set to be smaller than the aperture of the second opening hole 22, and the orthographic projection of the third opening hole 23 on the plane where the substrate 41 is located is located within the orthographic projection of the second opening hole 22 on the plane where the substrate 41 is located, which is equivalent to setting the first electrode layer 43 formed by the interior of the second opening hole 22 and the third opening hole 23 towards the opening hole to form a step form, and the first electrode layer 43 can have an inclined surface relative to the plane where the substrate 41 is located, and similarly, the first electrode layer 43 with a larger area inclined surface can realize specific reflection of the incident light through the first opening hole 21, and part of the light is reflected to the light shielding layer 44 and absorbed by the light shielding layer 44; in addition, the extension direction of the first side wall 51 and the extension direction of the third side wall 53 are different, which can realize specific direction reflection of more incident light through the first electrode layer 43 with the specific structure, realize customized direction reflection of ambient light, thereby further reducing the number of light emitted from the first opening hole 21 after being reflected by the first electrode layer 43, weakening the influence of the reflected light on the display effect of the display panel 100, thereby facilitating to improve the display uniformity of the display panel 100, and further improving the user experience. Figure 3

[0143] Please refer to Figures 4-23 、 Figure 5 and Figure 1 ​Optionally, the first aperture 21 has a first symmetry axis 61 extending in a direction perpendicular to the plane where the display panel 100 is located, and the second aperture 22 has a second symmetry axis 62 extending in a direction perpendicular to the plane where the display panel 100 is located, and the first symmetry axis 61 and the second symmetry axis 62 do not overlap.

[0144] Specifically, the hole combination 20 proposed in the present application is designed asymmetrically, and specifically, when the symmetry axis (the first symmetry axis 61) of the first aperture 21 in the plane where the display panel 100 is located and the symmetry axis (the second symmetry axis 62) of the second aperture 22 in the plane where the display panel 100 is located are parallel, the first symmetry axis 61 and the second symmetry axis 62 do not overlap; here, the present application does not limit whether the apertures of the first aperture 21 and the second aperture 22 are the same, as long as a certain spacing is included between the symmetry axes of the first aperture 21 and the second aperture 22. As shown in the principle of the same as Figure 3 shown, by setting the hole combination 20 asymmetrically, it can be ensured that at least part of the light rays incident from the first aperture 21 to the surface of the first electrode layer 43 corresponding to the position of the second aperture 22 are reflected to the light shielding layer 44 beside the first aperture 21 and absorbed by the light shielding layer 44, rather than being emitted from the first aperture 21 after being reflected twice, so that the light rays incident from the first aperture 21 to the surface of the first electrode layer 43 corresponding to the position of the second aperture 22 will not all be reflected to the first aperture 21, that is, the light rays reflected by the first electrode layer 43 and emitted from the first aperture 21 are reduced or even eliminated, which weakens the influence of the reflected light on the display effect of the display panel 100, thereby improving the display uniformity of the display panel 100 and further improving the user experience.

[0145] Please refer to Figures 4-23 , Figure 1 and Figure 3 Optionally, the aperture of the first aperture 21 and the aperture of the second aperture 22 are the same.

[0146] Specifically, any hole combination 20 provided in the present application can be configured such that the diameters of the first opening 21 and the second opening 22 are the same, for example, when the first opening 21 and the second opening 22 are both circular, the first opening 21 and the second opening 22 can be configured to have the same area of the orthographic projection on the plane where the display panel 100 is located, at this time, the center 210 of the first opening 21 in the orthographic projection on the plane where the substrate 41 is located and the center 220 of the second opening 22 in the orthographic projection on the plane where the substrate 41 is located can be configured not to overlap, so as to ensure that the first opening 21 and the second opening 22 in the hole combination 20 are designed asymmetrically; and / or, the corresponding first electrode layer 43 in the second opening 22 can also be configured to be non-planar; so that the light rays incident from the first opening 21 to the surface of the first electrode layer 43 at the corresponding position of the second opening 22 can exist at least part of the light rays being reflected to the light shielding layer 44 beside the first opening 21 and being absorbed by the light shielding layer 44, thus the light rays incident from the first opening 21 to the surface of the first electrode layer 43 at the corresponding position of the second opening 22 will not all be reflected to the first opening 21, the light rays emitted from the first opening 21 after being reflected by the first electrode layer 43 are reduced, and the influence of the reflected light rays on the display effect of the display panel 100 is weakened, thereby being conducive to improving the display uniformity of the display panel 100, and further improving the user experience.

[0147] Please refer to Figures 4-23 , Figure 24 and Figure 1 Optionally, the first opening 21 in the orthographic projection on the plane where the substrate 41 is located includes a first interval D between the edge of the orthographic projection and the edge of the orthographic projection of the second opening 22 close to one side thereof, and the radius of the first opening 21 is R; D≤0.3154R.

[0148] Specifically, the present application provides an optional embodiment, the first opening 21 in the orthographic projection on the plane where the substrate 41 is located and the second opening 22 in the orthographic projection on the plane where the substrate 41 is located include a non-overlapping part, at this time, there is a first interval D between the edge of the orthographic projection on the plane where the substrate 41 is located and the edge of the orthographic projection on the plane where the substrate 41 is located close to one side thereof.

[0149] For example, when the diameters of the first aperture 21 and the second aperture 22 are set to be the same, with a radius of R and a first distance of D, one of the centers is connected to the intersection point, and a perpendicular line is drawn from the intersection point, as shown in the figure; let the opening angle be θ, then cosθ = D / 2R, and the opening angle 2θ corresponds to the pie-shaped area S = R^2θ; subtract the triangular area to obtain the intersection area of the two circles S = 2R^2θ-DRsinθ, which determines the transmittance; as the offset distance increases, the transmittance will decrease while the anti-reflection effect improves, T% = S / πR2; according to the current light transmission hole standard of 1.25%, the minimum acceptable is 1%, that is, the acceptable range is T% ≥ 80%; substituting can be solved to obtain: D ≤ 0.3154R.

[0150] Optionally, the aperture of the first aperture 21 is smaller than the aperture of the second aperture 22.

[0151] Specifically, any hole combination 20 provided by the present application can be set such that the diameters of the first aperture 21 and the second aperture 22 are different, for example, when the first aperture 21 and the second aperture 22 are both circular, the diameter of the first aperture 21 can be set to be smaller than the diameter of the second aperture 22; at this time, the projection of the center 210 of the first aperture 21 on the plane of the substrate 41 and the projection of the center 220 of the second aperture 22 on the plane of the substrate 41 can be selected not to overlap, to ensure that the hole combination 20 is designed asymmetrically; and / or, the corresponding first electrode layer 43 in the second aperture 22 can also be selected to be non-planar; in this way, the light rays incident from the first aperture 21 to the surface of the first electrode layer 43 at the corresponding position of the second aperture 22 can have at least part of the light rays reflected to the light shielding layer 44 beside the first aperture 21 and absorbed by the light shielding layer 44, so that the light rays incident from the first aperture 21 to the surface of the first electrode layer 43 at the corresponding position of the second aperture 22 will not all be reflected out of the first aperture 21, reducing the light rays reflected by the first electrode layer 43 and then emitted from the first aperture 21, weakening the influence of the reflected light rays on the display effect of the display panel 100, thereby facilitating the improvement of the display uniformity of the display panel 100 and further improving the user experience.

[0152] Figure 24 Another perspective view of the hole combination provided by the present application is shown Figure 1 , please refer to the foregoing cross-sectional view Figure 3 Optionally, the projection of the first aperture 21 on the plane of the substrate 41 is located within the projection of the second aperture 22 on the plane of the substrate 41.

[0153] Specifically, any hole combination 20 provided in the present application can be provided with first and second openings 21 and 22 with different diameters, for example, when the first and second openings 21 and 22 are both circular, the diameter of the first opening 21 can be smaller than that of the second opening 22; at this time, the normal projection of the first opening 21 on the plane of the substrate 41 can be further provided to be located within the normal projection of the second opening 22 on the plane of the substrate 41, the ambient light incident from the first opening 21 will hit the surface of the first electrode layer 43 at the corresponding position of the second opening 22, at this time, for example, the surface of the first electrode layer 43 receiving the incident ambient light can be provided to include a non-planar surface, to achieve a specific reflection of the light rays incident through the first opening 21, and part of the light rays are reflected to the light shielding layer 44 and absorbed thereby, so as to be able to reduce the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, to weaken the influence of the reflected light rays on the display effect of the display panel 100, thereby facilitating to improve the display uniformity of the display panel 100, and further improving the user experience.

[0154] Please refer to Figure 7 , Figure 25 and Figure 3 Optionally, the second opening 22 includes a first side wall 51, and the first side wall 51 and the bottom surface of the first insulating layer 42 form a first included angle a1, and the angle of the first included angle a1 is a1, and 20°≤a1≤40°.

[0155] Specifically, the present application provides that the first included angle a1 formed between the plane where the first side wall 51 of the second opening 22 is located and the bottom surface of the first insulating layer 42 is in the range of 20°-40° (including the original value), so that the first side wall 51 has a certain degree of inclination, and the inclination is not too large; and the value of the first included angle a1 in this range can also make the area of the first side wall 51 large enough, and a too large angle will make the area of the first side wall 51 relatively small, and the first electrode layer 43 with a larger area of the inclined surface can achieve a specific reflection of the light rays incident through the first opening 21, and part of the light rays are reflected to the light shielding layer 44 and absorbed thereby, so as to be able to make the incident light be reflected in a specific direction through the first electrode layer 43 with a specific structure, to achieve a customized directional reflection of the ambient light, thereby being able to reduce the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, to weaken the influence of the reflected light rays on the display effect of the display panel 100, thereby facilitating to improve the display uniformity of the display panel 100, and further improving the user experience.

[0156] Figure 1 Another cross-sectional view of AA' in Figure 3 provided by the embodiments of the present application is shown, please refer to Figure 25 , Figure 1 and Figure 3Optionally, the second opening 22 comprises a first side wall 51 and a second side wall 52, the first side wall 51 and the second side wall 52 are directly connected.

[0157] The second side wall 52 is located on the first side of the projection of the geometric center of the second opening 22 on the plane where the substrate 41 is located.

[0158] Specifically, the first electrode layer 43 at the position of the second opening 22 is designed to be non-planar, the first side wall 51 and the second side wall 52 of the second opening 22 are directly connected without other planes, and the first electrode layer 43 at the position of the second opening 22 comprises at least two connected inclined surfaces. When the projection of the geometric center of the second opening 22 on the plane where the substrate 41 is located is located on the first side of the projection of the geometric center of the first opening 21 on the plane where the substrate 41 is located, the projection of the second side wall 52 on the plane where the substrate 41 is located is located on the first side of the projection of the geometric center of the second opening 22 on the plane where the substrate 41 is located, so that the first electrode layer 43 arranged on the surface of the first side wall 51 can reflect more incident light to the light shielding layer 44, avoiding the problem of deterioration of the reflectivity of the display panel 100 caused by reflected light.

[0159] That is, through the above arrangement, the first electrode layer 43 with a specific inclined surface can make the incident light be reflected in a specific direction, realizing the customized direction of the reflection of ambient light, so as to reduce the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, weaken the influence of reflected light on the display effect of the display panel 100, thereby improving the display uniformity of the display panel 100 and further improving the user experience.

[0160] Please continue to refer to Figure 25 , Figure 26 and Figure 1 Optionally, a fourth included angle is formed between the first side wall 51 and the second side wall 52 in the second opening 22, the fourth included angle is α4, and 90°<α4<180°.

[0161] Specifically, the first electrode layer 43 at the position of the second opening 22 is designed to be non-planar, the first side wall 51 and the second side wall 52 of the second opening 22 are directly connected without other planes, and the first electrode layer 43 at the position of the second opening 22 includes at least two connected inclined surfaces. The fourth included angle between the first side wall 51 and the second side wall 52 is limited to 90°-180° (not including the original value), so that the area of the inclined surface of the first electrode layer 43 is relatively large, and the area of the first side wall 51 is relatively small when the angle is too large. The first electrode layer 43 with a larger area of the inclined surface can reflect the light rays incident through the first opening 21 to the light shielding layer 44 and be absorbed by the light shielding layer 44, so that the incident light can be reflected in a specific direction by the first electrode layer 43 with a specific structure, and the customized direction of the ambient light can be reflected, thereby reducing the number of light rays emitted from the first opening 21 after being reflected by the first electrode layer 43, weakening the influence of the reflected light on the display effect of the display panel 100, thereby improving the display uniformity of the display panel 100, and improving the user experience.

That is, the number of openings included in the hole combination 20 is not specifically limited, and the arrangement between the openings can also be adjusted according to the requirements.

[0163] In addition, Figure 30 , Figures 1-29An embodiment of the hole combination 20 is shown, which includes a first opening 21, a second opening 22, a third opening 23, and a fourth opening 24. The fourth opening 24 can be formed by the film layer position where the third insulating layer 48 is located, and the specific arrangement positions among the first opening 21, the second opening 22, the third opening 23, and the fourth opening 24 can also be adjusted according to requirements.

Please refer to ​ According to the same inventive concept, the present application also provides a display device 200, which includes the display panel 100 provided by any of the display panels 100. ​ It should be noted that the embodiments of the display device 200 provided by the embodiments of the present application can refer to the embodiments of the display panel 100 described above, and repeated descriptions are not repeated.

[0165] As can be seen from the above embodiments, the display panel and the display device provided by the present application at least achieve the following beneficial effects:

[0166] The present application provides a display panel and a display device. The display panel includes a hole combination. A first opening in the hole combination penetrates a light shielding layer. A second opening in the hole combination is disposed on a first insulating layer. The hole combination is designed asymmetrically, and / or the first electrode layer disposed at the position corresponding to the second opening is a non-planar structure. When the light incident from the first opening irradiates the surface of the first electrode layer, the incident light is not totally reflected by the first electrode layer to the first opening. That is, the first opening and the second opening are asymmetrically arranged, so that at least part of the light incident from the first opening is reflected by the first electrode layer in the second opening to the surface of the light shielding layer close to the first electrode layer and is absorbed by the light shielding layer. The ambient light entering from the first opening is reflected in different directions by the non-planar first electrode layer, so that part of the light is reflected to the surface of the light shielding layer close to the first electrode layer and is absorbed by the light shielding layer. Thus, the light reflected by the first electrode layer and then emitted from the first opening is reduced, the influence of the reflected light on the display effect of the display panel is avoided, the display uniformity of the display panel is improved, and the user experience is improved.
