Detailed Implementation Methods

[0030] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0031] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0032] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0033] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0034] In the description of this specification, it should be understood that the terms "substantially", "approximately", "about", "about", "generally", "largely" used in the claims and embodiments of this application refer to values ​​that can be generally agreed upon within a reasonable range of process operations or tolerances, rather than a precise value.

[0035] It should be understood that although the terms "first," "second," "third," etc., may be used to describe light-emitting devices, pixel circuits, etc., in the embodiments of this application, these light-emitting devices, pixel circuits, etc., should not be limited to these terms. These terms are only used to distinguish light-emitting devices, pixel circuits, etc., from each other. For example, without departing from the scope of the embodiments of this application, a first light-emitting device may also be referred to as a second light-emitting device, and similarly, a second light-emitting device may also be referred to as a first light-emitting device.

[0036] Through meticulous and in-depth research, the applicant in this case has provided a solution to the problems existing in the prior art.

[0037] Figure 1 This is a cross-sectional view of a display panel provided in an embodiment of this application. Figure 2 This is a cross-sectional view of another display panel provided in an embodiment of this application. Figure 3 This is a planar projection view of the light-emitting layer and color resist layer in a display panel provided in an embodiment of this application. Figure 4 This is a planar projection view of the light-emitting layer and color resist layer in another display panel provided in an embodiment of this application.

[0038] like Figure 1 and Figure 2 As shown, the display panel 01 provided in this application embodiment includes a substrate 10, a light-emitting layer, a color resist layer, and a light-shielding layer disposed on one side of the substrate 10. In addition, it may also include a circuit layer, a first insulating layer 100, a touch layer, etc.

[0039] The circuit layer includes multiple pixel circuits 20, each corresponding one-to-one with a sub-pixel of the display panel 01, used to provide the driving voltage or driving current required for the sub-pixels to emit light. It should be noted that... Figure 1 The illustration only shows that the display panel 01 includes pixel circuitry 20. The actual pixel circuitry may include at least two transistors and may also include other electrical components such as resistors and capacitors.

[0040] The light-emitting layer includes multiple light-emitting devices 30, which may include multiple first light-emitting devices 31, multiple second light-emitting devices 32, and multiple third light-emitting devices 33. Each of the first, second, and third light-emitting devices 31 corresponds to a different sub-pixel. Pixel circuits 20 are electrically connected to the light-emitting devices 30 in a one-to-one correspondence. Pixel circuits 20 provide the driving voltage or driving current required for sub-pixel light emission, specifically providing the necessary driving voltage or driving current for the light-emitting devices 30 to emit light. Specifically, the multiple pixel circuits 20 include a first pixel circuit 21, a second pixel circuit 22, and a third pixel circuit 23. The first pixel circuit 21 is electrically connected to the first light-emitting device 31, the second pixel circuit 22 is electrically connected to the second light-emitting device 32, and the third pixel circuit 23 is electrically connected to the third light-emitting device 33.

[0041] A first insulating layer 100 is disposed between the circuit layer and the light-emitting layer, and the first insulating layer 100 includes a plurality of vias H0. The pixel circuit 20 and the corresponding light-emitting device 30 are electrically connected through the vias H0. Among the plurality of vias H0, there are a first via H1, a second via H2 and a third via H3. The first light-emitting device 31 can be electrically connected to the first pixel circuit 21 through the first via H1, the second light-emitting device 32 can be electrically connected to the second pixel circuit 22 through the second via H2, and the third light-emitting device 33 can be electrically connected to the second pixel circuit 23 through the third via H3.

[0042] The touch layer may include multiple touch electrodes 40, which may be mutually insulated transparent conductive electrodes or mutually insulated metal mesh electrodes; they may be self-capacitance electrodes or mutual-capacitance electrodes.

[0043] The color resist layer includes multiple color resist blocks 50, each corresponding to a light-emitting device 30. Along the thickness direction Z of the display panel, the color resist blocks 50 are positioned on the side of the light-emitting device 30 facing the light-emitting surface of the display panel 01. The multiple color resist blocks 50 may include a first-color color resist block 51, a second-color color resist block 52, and a third-color color resist block 53, each being a color resist block 50 of a different color. Specifically, the first-color color resist block 51 is positioned on the side of the first light-emitting device 31 facing the light-emitting surface of the display panel 01, the second-color color resist block 52 is positioned on the side of the second light-emitting device 32 facing the light-emitting surface of the display panel 01, and the third-color color resist block 53 is positioned on the side of the third light-emitting device 33 facing the light-emitting surface of the display panel 01.

[0044] In this process, the color of light passing through the color resist block 50 can be filtered to match the color of the color resist block 50. For example, if multiple light-emitting devices 30 all emit white light, the white light emitted by the first light-emitting device 31 will become the first color light after passing through the first color resist block 51; the white light emitted by the second light-emitting device 32 will become the second color light after passing through the second color resist block 52; and the white light emitted by the third light-emitting device 33 will become the third color light after passing through the third color resist block 53. Alternatively, multiple light-emitting devices 30 can emit different colors of light. The first color light emitted by the first light-emitting device 31 will become a purer first color light after passing through the first color resist block 51; the second color light emitted by the second light-emitting device 32 will become a purer second color light after passing through the second color resist block 52; and the third color light emitted by the third light-emitting device 33 will become a purer third color light after passing through the third color resist block 53.

[0045] Please combine Figure 1 , Figure 2 and Figure 3 , Figure 4 The light-shielding layer 60 is located on the side of the light-emitting layer facing the light-emitting surface of the display panel 01, and the light-shielding layer 60 includes a plurality of first openings 61, with a first light-shielding portion 610 formed between two adjacent first openings 61. Along the thickness direction Z of the display panel, the projection of the first opening 61 onto the color resist layer covers at least two color resist blocks 50, and the two color resist blocks 50 covered by the first opening 61 are of different colors. For example, two of the two color resist blocks 50 at least covered by the projection of the first opening 61 onto the color resist layer are a first color color resist block 51 and a second color color resist block 52. That is, the first opening 61 provided on the light-shielding layer 60 exposes at least simultaneously the first color color resist block 51 and the second color color resist block 52.

[0046] In this embodiment of the application, by simultaneously exposing at least two colors of color resist blocks through the first opening 61, the light-emitting area of ​​the sub-pixels can be increased, thereby improving the display brightness of the display panel 01 and ensuring that the display panel 01 also has high display brightness at wide viewing angles.

[0047] In one embodiment of this application, such as Figure 3 As shown in Figure 4, in two adjacent first openings 61, the color of at least one color resist block 50 covered by one first opening 61 is different from the color of at least one color resist block 50 covered by the other first opening 61.

[0048] In the display panel, the light emitted by the light-emitting device 30 undergoes diffraction during its emission towards the light-emitting surface due to the presence of light-blocking parts, resulting in dispersion. In this embodiment, at least two color resist blocks 50 of different colors are located in different first openings 61, respectively, covering two adjacent first openings 61. Since the diffraction conditions near adjacent first openings 61 are basically the same, sub-pixels of different colors that are close to each other undergo basically consistent dispersion at positions with basically the same diffraction conditions, ensuring the uniformity of the display.

[0049] In one implementation of this embodiment, such as Figure 3 As shown, the light-shielding layer 60 includes a first opening 61 and a plurality of second openings 62. The projection of the first opening 61 onto the color resist layer covers two color resist blocks 50, while the projection of the second opening 62 onto the color resist layer covers only one color resist block 50. Furthermore, in the projections of adjacent first openings 61 onto the color resist layer, the two color resist blocks 50 covered by one first opening 61 are respectively the first color color resist block 51 and the second color color resist block 52, while the two color resist blocks 50 covered by the other first opening 61 are respectively the first color color resist block 51 and the third color color resist block 53. The projection of the second opening 62 onto the color resist layer covers the third color color resist block 53.

[0050] In another implementation of this embodiment, such as Figure 4 As shown, the light-shielding layer 60 includes a first opening 61 and a plurality of second openings 62. Part of the first opening 61 is a first sub-opening 61a, whose projection on the color resist layer covers two color resist blocks 50 of different colors; another part of the first opening 61 is a second sub-opening 61b, whose projection on the color resist layer covers three color resist blocks 50; the projection of the second opening 62 on the color resist layer covers one color resist block. Specifically, the two color resist blocks 50 covered by the projection of the first sub-opening 61a on the color resist layer are a first-color color resist block 51 and a second-color color resist block 52, respectively; the three color resist blocks 50 covered by the projection of the second sub-opening 61b on the color resist layer are a first-color color resist block 51, a second-color color resist block 52, and a third-color color resist block 53, respectively.

[0051] In this implementation, the second opening 62 exposes the third color resist block 53 that is not exposed by the first opening 61, which can improve the problem of the third color light bias when the display panel 01 is displayed to a certain extent, and thus effectively solve the problem of the third color light bias when the display panel 01 is displayed from a wide viewing angle. In this embodiment, by flexibly setting the density of the second opening 62, the display brightness of the display panel 01 and the wide viewing angle color bias problem can be effectively improved. In addition, the first color resist block 51 can be a red color resist block, the second color resist block 52 can be a green color resist block, and the third color resist block 53 can be a blue color resist block. In this embodiment, by setting light-shielding parts around some of the blue color resist blocks and exposing another part of the blue color resist blocks, along with the adjacent red and green color resist blocks, simultaneously through the first opening 61, the display brightness of the display panel 01 and the wide viewing angle blue bias problem can be effectively improved.

[0052] In one technical solution corresponding to this implementation method, such as Figure 3 and Figure 4 As shown, the openings of the light-shielding layer 60 are distributed in a first repeating unit C1, which includes at least two first openings 61 and at least two second openings 62. That is, in this technical solution, at least two first openings 61 and at least two second openings 62 constitute a first repeating unit C1, and the first repeating unit C1 is repeatedly arranged, thereby making the first openings 61 and second openings 62 arranged in a specific pattern.

[0053] In one implementation, the number of second openings 62 around any two adjacent first openings 61 is different. In a preferred embodiment, the first openings 61 and second openings 62 are arranged irregularly. This breaks the regularity of the opening arrangement and weakens the diffraction conditions.

[0054] In one technical solution corresponding to this embodiment, such as Figures 1-4 As shown, in at least two color resist blocks 50 covered by the projection of the first opening 61 onto the color resist layer, adjacent color resist blocks 50 partially overlap to form a second light-shielding portion 500. That is, among the color resist blocks 50 exposed by the first opening 61, adjacent color resist blocks 50 overlap to form a second light-shielding portion 500. This avoids color mixing problems in areas where adjacent sub-pixels are close to each other.

[0055] like Figure 3 and Figure 4 As shown, when the first opening 61 exposes two color resist blocks 50, the two color resist blocks 50 overlap in the area where they are close to each other to form a second light-blocking part 500; when the first opening 62 exposes three color resist blocks 50, the three color resist blocks 50 also overlap in the area where they are close to each other. In addition, the overlapping position of the color resist blocks 50 can be the overlap of two colors of color resist blocks 50 or the overlap of three colors of color resist blocks 50.

[0056] Furthermore, when the first color resist 51 is a red color resist, the second color resist 52 is a green color resist, and the third color resist 53 is a blue color resist, among the first color resist 51, the second color resist 52, and the third color resist 53 simultaneously covered by the same first opening 61, the overlap width between the third color resist 53 and the adjacent first color resist 51 and / or second color resist 52 is greater than the overlap width between the first color resist 51 and the second color resist 52. This increases the light-emitting area of ​​the corresponding sub-pixels of the first color resist 51 and the second color resist 52, while making the light-emitting area of ​​the third color resist 53 smaller, thus alleviating the problem of the display panel 01 appearing bluish at wide viewing angles.

[0057] In one implementation of this technical solution, the width of the first light-shielding portion 600 and the width of the second light-shielding portion 500 are different in a plane parallel to the substrate 10. In a preferred embodiment, the width of the first light-shielding portion 600 may be greater than the width of the second light-shielding portion 500.

[0058] In one implementation of this technical solution, in the projections of two adjacent first openings 61 onto the color resist layer, the area of ​​the second light-blocking portion 500 covered by the projection of one first opening 61 is different from the area of ​​the second light-blocking portion 500 covered by the projection of the other first opening 61. In a preferred embodiment, in the projections of two adjacent first openings 61 onto the color resist layer, the width of the second light-blocking portion 500 covered by the projection of one first opening 61 is different from the width of the second light-blocking portion 500 covered by the projection of the other first opening 61.

[0059] For example, such as Figure 3 As shown, when the projections of all the first openings 61 in the light-shielding layer 60 cover two color resist blocks 50 and there is an overlap between the two color resist blocks 50 to form a second light-shielding portion 500, in two adjacent first openings 61, the second light-shielding portion 500 covered by one first opening 61 is specifically the second light-shielding portion 500a, and the second light-shielding portion 500 covered by the other first opening 61 is specifically the second light-shielding portion 500b. The areas of the second light-shielding portion 500a and the second light-shielding portion 500b are different; specifically, the widths of the second light-shielding portion 500a and the second light-shielding portion 500b are different.

[0060] For example, such as Figure 4As shown, when part of the first opening 61 is a first sub-opening 61a covering two color resist blocks 50 of different colors, and another part of the first opening 61 is a second sub-opening 61b covering three color resist blocks 50, the two first openings adjacent to and between the second sub-opening 61b are specifically the first sub-opening 61a. The second light-shielding portions 500 covered by these two first sub-openings 61a are respectively the second light-shielding portion 500a and the second light-shielding portion 500b. The second light-shielding portion 500 covered by the second sub-opening 61b is specifically the second light-shielding portion 500c. The areas of the second light-shielding portions 500a, 500b, and 500c are all different; specifically, the widths of the second light-shielding portions 500a, 500b, and 500c are all different. This design can reduce the regularity of the light-shielding portions within a certain area, thereby mitigating diffraction phenomena.

[0061] Figure 5 This is a planar projection view of the light-emitting layer and color resist layer in another display panel provided in an embodiment of this application.

[0062] In one embodiment of this application, such as Figure 4 and Figure 5 As shown, the plurality of first openings 61 include a first sub-opening 61a and a second sub-opening 61b. The number of color resist blocks 50 covered by the projection of the first sub-opening 61a onto the color resist layer is X1, and the number of color resist blocks 50 covered by the projection of the second sub-opening 61b onto the color resist layer is X2, where X1 is not equal to X2. That is, the number of color resist blocks 50 covered by the projection of the first sub-opening 61a onto the color resist layer is different from the number of color resist blocks 50 covered by the projection of the second sub-opening 61b onto the color resist layer. For example, as... Figure 4 and Figure 5 As shown, X1 = 2, X2 = 3, meaning the projection of the first sub-opening 61a onto the color resist layer covers two color resist blocks 50, and the projection of the second sub-opening 61b onto the color resist layer covers three color resist blocks 50. This design can further reduce the regularity of the light-blocking part within a certain area, thereby mitigating diffraction phenomena.

[0063] In one implementation of this embodiment, such as Figure 4 As shown, the three color resist blocks 50 covered by the second sub-opening 61b are arranged in a straight line along the first direction X, and the two color resist blocks 50 covered by the first sub-opening 61a are also arranged along the first direction X. For example, as Figure 4 As shown, the second sub-opening 61b extends along the first direction X and the first color resist block 51, the second color resist block 52 and the third color resist block 53 exposed therein are arranged along the first direction X; the first sub-opening 61a extends along the first direction X and the first color resist block 51 and the second color resist block 52 exposed therein are arranged along the first direction X.

[0064] In another implementation of this embodiment, as shown in Figure 5 , the three color resist blocks 50 covered by the second sub-opening 61b are arranged in a triangular shape, and the two color resist blocks 50 covered by the first sub-opening 61a are arranged in a straight line along the first direction X. For example, as shown in Figure 5 , among the first color resist block 51, the second color resist block 52 and the third color resist block 53 exposed by the second sub-opening 61b, the first color resist block 51 and the second color resist block 52 are arranged along the first direction X, and the third color resist block 53 is arranged with the first color resist block 51 and the second color resist block 52 along the second direction Y; the first sub-opening 61a extends along the first direction X, and the first color resist block 51 and the second color resist block 52 exposed thereby are arranged along the first direction X.

[0065] In this embodiment, further, the light shielding layer further comprises a second opening 62, and the projection of the second opening 62 on the color resist layer only covers one color resist block 50.

[0066] In one implementation of this embodiment, as shown in Figure 4 , when the three color resist blocks 50 covered by the second sub-opening 61b are arranged in a straight line along the first direction X, and the two color resist blocks 50 covered by the first sub-opening 61a are also arranged along the first direction X, the one color resist block 50 covered by the second opening 62 and the adjacent two color resist blocks 50 covered by the first-type opening 61a are arranged along the first direction X. That is, as shown in Figure 4 , the first sub-opening 61a extends along the first direction X, and the first color resist block 51 and the second color resist block 52 exposed thereby are arranged along the first direction X, and the third color resist block 53 exposed by the adjacent second opening 62 is arranged with the first color resist block 51 and the second color resist block 52 along the first direction X.

[0067] In another implementation of this embodiment, as shown in Figure 5 , when the three color resist blocks 50 covered by the second sub-opening 61b are arranged in a triangular shape and the two color resist blocks 50 covered by the first sub-opening 61a are also arranged along the first direction X, the two color resist blocks covered by the first sub-opening 61a and the one color resist block 50 covered by an adjacent second opening 62 are arranged in a triangular shape. That is, the first sub-opening 61a extends along the first direction X, and the first color resist block 51 and the second color resist block 52 exposed thereby are arranged along the first direction X, and the third color resist block 53 exposed by the adjacent second opening 62 is arranged with the first color resist block 51 and the second color resist block 52 along the second direction Y.

[0068] In a technical solution corresponding to this implementation, as shown in Figure 4 and Figure 5As shown, the openings of the light-shielding layer 60 are distributed in a second repeating unit C2. The second repeating unit C2 includes at least two first sub-openings 61a, at least two second sub-openings 61b, and at least two second openings 62. That is, in this technical solution, at least two first sub-openings 61a, at least two second sub-openings 61b, and at least two second openings 62 constitute a second repeating unit C2, and the second repeating unit C2 is repeatedly arranged, thereby causing the first sub-openings 61a, second sub-openings 61b, and second openings 62 to be arranged in a specific pattern.

Figure 7 This is a planar projection view of the light-emitting layer and the light-shielding layer in another display panel provided in an embodiment of this application.

[0071] In this embodiment, the light-emitting device 30 can specifically be an organic light-emitting device, which includes an anode, a cathode, and an organic light-emitting layer disposed between the anode and the cathode. Specifically, the first light-emitting device 31 may include a first anode 311, a first cathode 312, and a first organic light-emitting layer 313 disposed between the first anode 311 and the first cathode 312; the second light-emitting device 32 may include a second anode 321, a second cathode 322, and a second organic light-emitting layer 323 disposed between the second anode 321 and the second cathode 322; the third light-emitting device 33 may include a third anode 331, a third cathode 332, and a third organic light-emitting layer 333 disposed between the third anode 331 and the third cathode 332. The first cathode 312, the second cathode 322, and the third cathode 332 can be electrically connected to form a fully transparent conductive electrode, and the first anode 311, the second anode 323, and the third anode 333 can be metal electrodes.

[0072] In one embodiment of this application, a plurality of light-emitting devices 30 include a first type of light-emitting device, a plurality of pixel circuits 20 include a first type of pixel circuit, and a plurality of vias H0 include a first type of via, wherein the first type of light-emitting device is electrically connected to the first type of pixel circuit through the first type of via. In a plane perpendicular to the thickness direction Z of the display panel 01, the first type of light-emitting device is separated from its corresponding first type of via; along the thickness direction Z of the display panel 01, the first light-shielding portion 600 of the light-shielding layer 60 covers the first type of via.

[0073] like Figure 6 As shown, in the display panel 01 provided in this embodiment, the multiple pixel circuits 20 included in the circuit layer are arranged in a matrix along the first direction X and the second direction Y to facilitate the arrangement of signal lines and improve the space utilization of the pixel circuits 20; the multiple light-emitting devices 30 in the light-emitting layer are arranged along the first direction X to form a light-emitting device column, and the light-emitting devices in adjacent light-emitting device columns are staggered to facilitate rendering and improve white balance effect. Please refer to Figure 6 Some of the light-emitting devices 30 (i.e., the first type of light-emitting devices) are separated from the corresponding vias (i.e., the first type of vias). These light-emitting devices 30 (i.e., the first type of light-emitting devices) are electrically connected to the corresponding pixel circuit 20 (i.e., the first type of pixel circuit) through the connection electrode 200 extending to the area where the corresponding via (i.e., the first type of via) is located.

[0074] Please combine Figure 6 and Figure 7 The light-emitting device (i.e., the first type of light-emitting device) that is separated from the corresponding via (i.e., the first type of via) is covered by the first light-shielding part 600 of the light-shielding layer 60.

[0075] For example, such as Figure 6 As shown, the third light-emitting device 33 is a first-type light-emitting device, the third via H3 is a first-type via, and the third pixel circuit 23 is a first-type pixel circuit. Therefore, the third light-emitting device 33 is separated from the corresponding third via H3. The third anode 331 of the third light-emitting device 33 extends through the connecting electrode 200 to the third via H3 and is electrically connected to the corresponding third pixel circuit 23. Please refer to... Figure 6 and Figure 7 The third via H3 is not covered by the third anode 331, but the third via H3 is covered by the first light-shielding part 600 of the light-shielding layer 60.

[0076] Since the first type of via is separate from the corresponding first type of light-emitting device, the first type of via is not covered by the anode of the first type of light-emitting device. In this embodiment, by covering the first type of via with the first light-shielding part 600 of the light-shielding layer 60, the reflection of ambient light by the connecting electrode 200 in the first type of via can be avoided, thereby solving the dispersion problem of the sub-pixels around the first type of via.

[0077] Furthermore, the first light-shielding portion 600 of the light-shielding layer 60 also covers the connecting electrode.

[0078] In the embodiments of this application, please continue to refer to Figure 6The plurality of light-emitting devices 30 may further include a second type of light-emitting device, the plurality of pixel circuits 20 may include a second type of pixel circuit, and the plurality of vias H0 may include a second type of via. The second type of light-emitting device and the second type of pixel circuit are electrically connected through the second type of via. Along the thickness direction Z of the display panel 01, the second type of light-emitting device covers the corresponding second type of via, and in a plane perpendicular to the thickness direction Z of the display panel 01, the first light-shielding portion 600 of the light-shielding layer 60 is separate from the second type of via. That is, in the display panel 01, the anode of the second type of light-emitting device covers the corresponding second type of via, and the first light-shielding portion 600 of the light-shielding layer 60 no longer needs to cover the second type of via.

[0079] For example, such as Figure 6 As shown, the second light-emitting device 32 is a second type of light-emitting device, the second via H2 is a second type of via, and the second pixel circuit 22 is a second type of pixel circuit. Therefore, the second light-emitting device 32 covers the corresponding second via H2. The second anode 321 of the second light-emitting device 32 is directly electrically connected to the corresponding second pixel circuit 22 through the second via H2 below it. Please refer to... Figure 6 and Figure 7 The second via H2 is covered by the second anode 321, but is not covered by the first light-shielding part 600 of the light-shielding layer 60.

[0080] In this embodiment, since the second type of via is covered by the corresponding second type of light-emitting device, and the light-shielding part of the light-shielding layer on the light-emitting surface side of the second type of light-emitting device does not cover the area where the second type of via is located, the light emission rate of the sub-pixel corresponding to the second type of light-emitting device can be increased.

[0081] In the embodiments of this application, please continue to refer to Figure 6The plurality of light-emitting devices 30 may further include a third type of light-emitting device, the plurality of pixel circuits 20 include a third type of pixel circuit, and the plurality of vias H0 include a third type of via, wherein the third type of light-emitting device and the third type of pixel circuit are electrically connected through the third type of via. Along the thickness direction Z of the display panel 01, the third type of light-emitting device covers a portion of the third type of via corresponding to the third type of light-emitting device; in a plane perpendicular to the thickness direction Z of the display panel 01, the third type of light-emitting device is separated from the other portion of the third type of via corresponding to the third type of light-emitting device. Along the thickness direction Z of the display panel 01, the portion of the third type of via not covered by the third type of light-emitting device is covered by the first light-shielding portion 600 of the light-shielding layer 60. That is, in the display panel 01, the anode of the third type of light-emitting device only covers a portion of the third type of via corresponding to the third type of light-emitting device, and the first light-shielding portion 600 of the light-shielding layer 60 covers the portion of the third type of via not covered by the third type of light-emitting device. Furthermore, the first light-shielding portion 600 of the light-shielding layer 60 may also be separated from the area covered by the third type of light-emitting device in the third type of via.

[0082] For example, such as Figure 6 As shown, the first light-emitting device 31 is a type III light-emitting device, the first via H1 is a type III via, and the first pixel circuit 21 is a type III pixel circuit. Therefore, the first light-emitting device 31 covers a portion of the corresponding area of ​​the first via H1 and is separate from the other portion of the first via H1. The first anode 311 of the first light-emitting device 31 is directly electrically connected to the corresponding first pixel circuit 21 through the first via H1 below it. Please refer to... Figure 6 and Figure 7 The area in the first via H1 covered by the first anode 311 is not covered by the first light-shielding part 600 of the light-shielding layer 60, while the area in the first via H1 not covered by the first anode 311 is covered by the first light-shielding part 600 of the light-shielding layer 60.

[0083] In other words, the first via H1 is either covered by the first anode 311 or by the first light-shielding part 600 of the light-shielding layer 60. This ensures that the sub-pixel corresponding to the third type of light-emitting device has the maximum light-emitting area while avoiding dispersion problems caused by the reflection of external light.
