[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0046] The terms used in the embodiments of the present application are merely for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0047] Figure 1 A display brightness non-uniformity analysis schematic diagram in the prior art is shown in FIG. 1. Figure 1 As shown in FIG. 1, when a person's eye watches the display panel 01, the observation angle is different when observing different positions in different display areas. When the position of the person's eye relative to the display panel 01 is fixed, the observation angles of the watching positions 1 and 2 are α1 and α2, respectively. Taking the observation angle of the position 1 as an example, the observation angle is the included angle between the line connecting the position 1 on the display panel 01 and the normal direction of the position 1. When the position where the position 1 is located is a plane, the normal direction of the position 1 is the direction perpendicular to the plane where the position 1 is located; when the position where the position 1 is located is a curved surface, the normal direction of the position 1 is the direction perpendicular to the tangent plane of the curved surface where the position 1 is located. Figure 1Since α1 is less than α2, under normal circumstances, more light emitted from position 1 will be received by the human eye compared to position 2. This results in a difference in the amount of light received by the human eye when viewing position 1 and position 2, and a visual difference in the perceived brightness of position 1 and position 2. The final effect is uneven brightness of the screen display.

[0048] To address the problems existing in the prior art, this invention provides a display panel with different light-blocking structures at different positions in the display area. These light-blocking structures are used to balance the brightness differences caused by different viewing angles at different positions in the display area, so that the brightness received by the human eye when observing different positions is basically the same, thereby improving the problem of uneven visual brightness and enhancing the visual effect.

[0049] Figure 2 This is a top view schematic diagram of a display panel provided in an embodiment of the present invention. Figure 3 for Figure 2 An enlarged schematic diagram of position Z in the central region. Figure 4 for Figure 3 A schematic diagram of a cross-section at the position of the midtangent line A-A'. (Example) Figure 2 As shown, the display panel includes a display area AA and a non-display area NA.

[0050] like Figure 3 As shown, the display area AA includes a first display area AA1 and a second display area AA2, with the second display area AA2 located between the first display area AA1 and the non-display area AA. The display area AA includes a first light-emitting device 21 located in the first display area AA1 and a second light-emitting device 22 located in the second display area AA2. The display panel also includes a light-blocking structure 30, which includes a first light-blocking structure 31 and a second light-blocking structure 32. The first light-blocking structure 31 is adjacent to the first light-emitting device 21, and the second light-blocking structure 32 is adjacent to the second light-emitting device 22; that is, the first light-blocking structure 31 is located in the first display area AA1, and the second light-blocking structure 32 is located in the second display area AA2.

[0051] like Figure 4 As shown, the display panel includes a substrate 10 and a light-emitting device layer 20; the light-emitting device layer 20 is located on one side of the substrate 10, and both the first light-emitting device 21 and the second light-emitting device 22 are located on the light-emitting device layer 20. The first light-emitting device 21 and the second light-emitting device 22 are divided according to their positions in the display area. Both the first light-emitting device 21 and the second light-emitting device 22 include a stacked first electrode 2a, a light-emitting layer 2b, and a second electrode 2c. In one embodiment, both the first light-emitting device 21 and the second light-emitting device 22 include a red light-emitting device, a blue light-emitting device, and a green light-emitting device. In another embodiment, both the first light-emitting device 21 and the second light-emitting device 22 are white light-emitting devices.

[0052] The light-emitting device layer 20 further includes a pixel definition layer 24, which has multiple openings K. All light-emitting devices are located within the openings K. It can be seen that the first light-emitting device 21 and the second light-emitting device 22 are both located within the openings K of the pixel definition layer 24. The pixel definition layer 24 is used to separate adjacent light-emitting devices. The light-blocking structure 30 overlaps with the pixel definition layer 24, specifically the portion of the pixel definition layer 24 without openings K.

[0053] The light-blocking structure 30 is located on the side of the light-emitting device layer 20 away from the substrate 10. In the direction parallel to the plane of the substrate 10, the first light-blocking structure 31 is located between adjacent first light-emitting devices 21, and the second light-blocking structure 32 is located between adjacent second light-emitting devices 22.

[0054] In this embodiment of the invention, the display panel further includes an array layer 50 and a thin-film encapsulation layer 60. The array layer 50 is located between the substrate 10 and the light-emitting device layer 20. The array layer 50 includes a pixel circuit 51, which includes a thin-film transistor T and a storage capacitor Cst. One electrode of the thin-film transistor T is connected to the first electrode 2a of the light-emitting device. The pixel circuit 51 is used to drive the light-emitting device to emit light. The thin-film encapsulation layer 60 is located on the side of the light-emitting device layer 20 away from the substrate 10. The thin-film encapsulation layer 60 is used to encapsulate and protect the light-emitting device to ensure its lifespan. The light-blocking structure 30 is located on the side of the thin-film encapsulation layer 60 away from the substrate 10.

[0055] In this embodiment of the invention, the light-blocking structure 30 serves to block light. The light-blocking structure 30 has a certain thickness in the plane e perpendicular to the substrate 10, or it has a certain height relative to the light-emitting device layer 20. Different thicknesses or heights of the light-blocking structure 30 result in different light-blocking capabilities.

[0056] like Figure 4 As shown, the thickness d1 of the first light-blocking structure 31 is greater than the thickness d2 of the second light-blocking structure 32. The thickness of the light-blocking structure 30 affects the light emission of its adjacent light-emitting devices. When the human eye is... Figure 4 When viewing the display panel from the position shown, the distance between the human eye and the first display area AA1 is greater than the distance between the human eye and the second display area AA2. It can be understood that the viewing angle of the human eye when viewing the first display area AA1 is smaller than the viewing angle when viewing the second display area AA2.

[0057] Figure 4The diagram illustrates the light emission range l1 of the first light-emitting device 21 and the light emission range l2 of the second light-emitting device 22. The light emitted by the first light-emitting device 21 within its light emission range l1 can be received by the human eye, and the light emitted by the second light-emitting device 22 within its light emission range l2 can also be received by the human eye. Assuming the thickness of the first light-blocking structure 31 is the same as the thickness of the second light-blocking structure 32, then the light emitted by the first light-emitting device 21 is S1` (… Figure 4 The light emitted by the first light-emitting device 21 (as indicated by the dotted line in the diagram) can also be received by the human eye. At this time, the light-emitting range of the first light-emitting device 21 is l1'. It can be seen that the light-emitting range l1' is larger than the light-emitting range l1, meaning that more light emitted by the first light-emitting device 21 can be received by the human eye. In this embodiment of the invention, the thickness of the first light-blocking structure 31 is increased, making it larger than the thickness of the second light-blocking structure 32. Therefore, the first light-blocking structure 31 blocks part of the light emitted within the light-emitting range l1' that is directed towards the human eye, thus reducing the light-emitting range of the first light-blocking structure 31 to the light-emitting range l1. In this embodiment of the invention, the first light-blocking structure 31 reduces the amount of light emitted by the first light-emitting device 21 that can be directed towards the human eye, thereby balancing the brightness difference between the first display area AA1 and the second display area AA2 caused by different viewing angles. This reduces the brightness difference received by the human eye when observing the two areas, improving the problem of uneven visual brightness and enhancing the visual effect.

[0058] In other embodiments, Figure 5 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 5 As shown, the height h1 of the first light-blocking structure 31 is higher than the height h2 of the second light-blocking structure 32. The heights of the first light-blocking structure 31 and the second light-blocking structure 32 are compared using a common reference plane in the display panel film layers. Figure 5 As illustrated, the vertical distance from the surface of the first light-blocking structure 31 away from the substrate 10 is the height h1 of the first light-blocking structure 31, and the vertical distance from the surface of the second light-blocking structure 32 away from the substrate 10 is the height h2 of the second light-blocking structure 32. The height of the light-blocking structure 30 affects the light emission of adjacent light-emitting devices. When the human eye is... Figure 5 When viewing the display panel from the position shown, the viewing angle of the human eye when viewing the first display area AA1 is smaller than the viewing angle when viewing the second display area AA2. Figure 5 The diagram illustrates the light emission range l1 of the first light-emitting device 21 and the light emission range l2 of the second light-emitting device 22. The light emitted by the first light-emitting device 21 within its light emission range l1 can be received by the human eye, and the light emitted by the second light-emitting device 22 within its light emission range l2 can also be received by the human eye. Assuming the height of the first light-blocking structure 31 is the same as the height of the second light-blocking structure 32, then the light emitted by the first light-emitting device 21 is S1` (…Figure 5 The light emitted by the first light-emitting device 21 (as indicated by the dotted line in the diagram) can also be received by the human eye. At this time, the light-emitting range of the first light-emitting device 21 is l1'. It can be seen that the light-emitting range l1' is larger than the light-emitting range l1, meaning that more light emitted by the first light-emitting device 21 can be received by the human eye. In this embodiment of the invention, the height of the first light-blocking structure 31 is increased, making it greater than the height of the second light-blocking structure 32. This causes the first light-blocking structure 31 to block part of the light emitted from the light-emitting range l1' towards the human eye, thus reducing the light-emitting range of the first light-blocking structure 31 to the light-emitting range l1. By using the first light-blocking structure 31, the amount of light emitted by the first light-emitting device 21 that can be directed towards the human eye can be reduced. This balances the brightness difference between the first display area AA1 and the second display area AA2 caused by different viewing angles, reducing the brightness difference received by the human eye when observing the two areas, improving the problem of uneven visual brightness, and enhancing the visual effect.

[0059] exist Figure 5 In this embodiment, the height h1 of the first light-blocking structure 31 is higher than the height h2 of the second light-blocking structure 32. In this embodiment, provided that the height relationship between the two structures is satisfied, the relationship between the thickness of the first light-blocking structure 31 and the thickness of the second light-blocking structure 32 is not limited.

[0060] Figure 4 and Figure 5 The illustrations all use a flat panel display. The first display area AA1 can be considered as the central area of ​​the display panel, and the second display area AA2 is the edge area near the non-display area NA. When viewing the display panel at a straight-viewing angle, the viewing angle of the first display area AA1 is smaller than the viewing angle of the second display area AA2. In this embodiment of the invention, the thickness d1 of the first light-blocking structure 31 is greater than the thickness d2 of the second light-blocking structure 32, or the height h1 of the first light-blocking structure 31 is greater than the height h2 of the second light-blocking structure 32. The light-blocking ability of the first light-emitting device 21 is greater than the light-blocking ability of the second light-emitting device 22. The first light-blocking structure 31 reduces the amount of light emitted by the first light-emitting device 21 that can be directed towards the human eye, thereby balancing the brightness difference between the first display area AA1 and the second display area AA2 caused by the different viewing angles. This reduces the brightness difference received by the human eye when observing the two areas, improves the problem of uneven visual brightness, and enhances the visual effect.

[0061] This invention also provides a curved display panel. Figure 6 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 6As shown, the first display area AA1 is a flat area, and the second display area AA2 is a curved area. When the user looks at the display panel from the position of the first display area AA, the viewing angle of the user from the first display area AA1 is α3, and the viewing angle of the user from the second display area AA2 is α4. It can be seen that α3 is smaller than α4. Figure 6 The diagram shows that the thickness of the first light-blocking structure 31 is greater than the thickness of the second light-blocking structure 32. By increasing the thickness of the first light-blocking structure 31, its light-blocking ability on the first light-emitting device 21 is increased. Thus, the first light-blocking structure 31 reduces the amount of light emitted by the first light-emitting device 21 that can be directed toward the human eye. This balances the brightness difference between the first display area AA1 and the second display area AA2 caused by different viewing angles, thereby reducing the brightness difference received by the human eye when observing the two areas, improving the problem of uneven brightness in vision, and enhancing the visual effect.

[0062] In another embodiment, the first display area AA1 is a planar area and the second display area AA2 is a curved area. The height of the first light-blocking structure 31 is set higher than the height of the second light-blocking structure 32. The first light-blocking structure 31 reduces the amount of light emitted by the first light-emitting device 21 that can be directed toward the human eye. This balances the brightness difference between the first display area AA1 and the second display area AA2 caused by different viewing angles, thereby reducing the brightness difference received by the human eye when observing the two areas, improving the problem of uneven visual brightness, and enhancing the visual effect.

[0063] In this embodiment of the invention, the first display area AA1 and the second display area AA2 can be either planar or curved, and there is no limitation on this. For ease of illustration, the first display area AA1 and the second display area AA2 are both planar areas in the following embodiments.

[0064] In some embodiments, Figure 7 This is a schematic diagram of another display panel provided in an embodiment of the present invention. Figure 7 The illustration only shows that the thickness of the first light-blocking structure 31 is greater than the thickness of the second light-blocking structure 32. Both the first light-emitting device 21 and the second light-emitting device 22 have a critical emission angle. The critical emission angle refers to the maximum angle formed between the light emitted from the edge of the light-emitting device that ultimately exits the display panel and the direction from which the light-emitting device is viewed directly. Figure 7In this embodiment, the direction facing the light-emitting device is parallel to the direction e perpendicular to the plane of the substrate 10. The first light-blocking structure 31 is adjacent to the first light-emitting device 21. The light emitted from the end of the first light-emitting device 21 closest to the first light-blocking structure 31 that is just not blocked by the first light-blocking structure 31 is called light ray S1-1. The angle between light ray S1-1 and the direction facing the first light-emitting device 21 is the critical emission angle θ1. Similarly, for the second light-emitting device 22, the light emitted from the end of the second light-blocking structure 32 that is just not blocked by the second light-blocking structure 32 is called light ray S2-1. The angle between light ray S2-1 and the direction facing the second light-emitting device 22 is the critical emission angle θ2. Wherein, θ1 < θ2. The critical emission angle affects the amount of light emitted by the light-emitting device. In this embodiment of the invention, setting θ1 < θ2 can reduce the amount of light emitted by the first light-emitting device 21, making the amount of light emitted by the first light-emitting device 21 less than the amount of light emitted by the second light-emitting device 22. This can reduce the amount of light emitted by the first light-emitting device 21 that can be directed toward the human eye, thereby balancing the brightness difference between the first display area AA1 and the second display area AA2 caused by different viewing angles. This reduces the brightness difference received by the human eye when observing the two areas, improves the problem of uneven brightness in vision, and enhances the visual effect.

[0065] In some embodiments, by setting the thickness or height relationship between the first light-blocking structure 31 and the second light-blocking structure 32, the critical emission angles of the first light-emitting device 21 and the second light-emitting device 22 can be adjusted, so that the critical emission angle of the first light-emitting device 21 is smaller than the critical emission angle of the second light-emitting device 22.

[0066] In some embodiments, Figure 8 for Figure 2 Another enlarged schematic diagram of the Z position in the central region. Figure 9 for Figure 8 A schematic diagram of a cross-section at the position of the midtangent line B-B'. (Combined with...) Figure 8 and Figure 9 The display panel includes a color resist layer 40 located on the side of the light-emitting device layer 20 away from the substrate 10. The color resist layer 40 includes a black matrix 41 and a plurality of color resist units 42. The black matrix 41 includes cutouts. Figure 8 The arrangement of the intermediate color resist units 42 is for illustrative purposes only and is not intended to limit the invention. Figure 8As can be seen, in the film layer stacking direction of the display panel, the cutouts of the black matrix 41 overlap with the light-emitting device. In the same direction, the color resist unit 42 overlaps with the cutouts of the black matrix 41, and also overlaps with the light-emitting device. The black matrix 41 has light-shielding properties, while the color resist unit 42 has light-filtering properties. The color resist unit 42 includes at least red, green, and blue color resist units. The color resist unit 42 can filter out light of a different color than itself, allowing only light of the same color to pass through. When ambient light shines on the display panel, the red light component can penetrate the red color resist unit and be reflected by the metal structure below it. The reflected light remains red, and the red light incident on adjacent green or blue color resist units is confined within the display panel and cannot escape, thus reducing the reflected light emitted from the display panel. Utilizing the light-filtering characteristics of the color resist unit 42 reduces the reflection of ambient light by the display panel, improving the display effect.

[0067] Combination Figure 8 and Figure 9 The first light-blocking structure 31 comprises a stacked structure consisting of a black matrix 41 and a color resist portion 43. The color resist portion 43 includes a color resist unit 42 and also has light-blocking properties. The second light-blocking structure 32 includes the black matrix 41. However, the second light-blocking structure 32 only includes the black matrix 41 and does not include the color resist portion 43. By including the stacked black matrix 41 and color resist portion 43 in the first light-blocking structure 31, the thickness of the first light-blocking structure 31 can be increased, making the thickness d1 of the first light-blocking structure 31 greater than the thickness d2 of the second light-blocking structure 32. This increases the light-blocking capability of the first light-emitting device 21, reducing the amount of light emitted by the first light-emitting device 21 that can be directed towards the human eye. This balances the brightness difference between the first display area AA1 and the second display area AA2 caused by different viewing angles, reducing the brightness difference received by the human eye when observing the two areas, improving the problem of uneven visual brightness, and enhancing the visual effect. In this embodiment, the color resist layer 40 is used to reduce the reflection of ambient light by the display panel, thereby improving the display effect. At the same time, the first light-blocking structure 31 is made using the black matrix 41 and color resist units 42 in the color resist layer 40, and the second light-blocking structure 32 is made using the black matrix 41 in the color resist layer 40. Without adding new process technology, it can also improve the problem of uneven visual brightness caused by different viewing angles.

[0068] like Figure 9 As shown, the color resist portion 43 includes a first stacked structure composed of color resist units 42 of at least two colors, which enables the color resist portion 43 to have light-blocking properties. Optionally, the edges of adjacent color resist units 42 of different colors overlap to form the color resist portion 43. Figure 9The schematic diagram shows that the color resist unit 43 includes overlapping first color resist unit 42-1 and second color resist unit 42-2, and the first color resist unit 42-1 and the second color resist unit 42-2 are different colors. The first color resist unit 42-1 and the second color resist unit 42-2 are any two of red color resist unit, green color resist unit, and blue color resist unit.

[0069] The second light-blocking structure 32 includes a black matrix 41. Figure 9 In the embodiment, it is shown that the color resist unit 42 adjacent to the second light-blocking structure 32 in the second display area AA2 does not overlap with the second light-blocking structure 32.

[0070] In some embodiments, the first light-blocking structure 31 includes a stacked structure composed of a black matrix 41 and a color resist portion 43, with the color resist portion 43 located on the side of the black matrix 41 away from the substrate 10; the second light-blocking structure 32 includes the black matrix 41. The thickness of the black matrix 41 located in the first display area AA1 is less than the thickness of the black matrix 41 located in the second display area AA2. This configuration, using the stacked black matrix 41 and color resist portion 43 as the first light-blocking structure 31, increases the thickness of the first light-blocking structure 31, thereby increasing its light-blocking capability. Reducing the thickness of the black matrix 41 within the first display area AA also ensures that the thickness of the first light-blocking structure 31 is not significantly greater than the thickness of the second light-blocking structure 32, thus achieving a suitable light-blocking thickness while also contributing to the flatness of the film layer.

[0071] In other embodiments, the first light-blocking structure 31 includes a stacked structure composed of a black matrix 41 and a color resist portion 43, with the color resist portion 43 located on the side of the black matrix 41 away from the substrate 10; the second light-blocking structure 32 includes the black matrix 41. The thickness of the portion of the color resist unit 40 located in the first display area AA1 that overlaps with the black matrix 41 is less than the thickness of the portion of the color resist unit 40 that overlaps with the first light-emitting device 21. This configuration, using the stacked black matrix 41 and color resist portion 43 as the first light-blocking structure 31, increases the thickness of the first light-blocking structure 31, thereby increasing its light-blocking capability. Conversely, reducing the thickness of the portion of the color resist unit 40 overlapping with the black matrix 41 in the first display area AA ensures that the thickness of the first light-blocking structure 31 is not significantly greater than the thickness of the second light-blocking structure 32, thus achieving a suitable light-blocking thickness while also contributing to the flatness of the film layer.

[0072] In another embodiment, Figure 10 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 10 As shown, the first light-blocking structure 31 includes a stacked structure composed of a black matrix 41 and a color resist portion 43, and the second light-blocking structure 32 includes the black matrix 41, with a color resist unit 42 overlapping the second light-blocking structure 32 at the location of the second light-blocking structure 32.Figure 10 As illustrated in regions Q1 and Q2, if only one type of color blocking unit 42 overlaps with the same position of the second light-blocking structure 32, then the color blocking unit 42 at the overlapping position in regions Q1 and Q2 cannot form a color blocking part and cannot play the role of blocking light. Figure 10 In the embodiment, the thickness of the second light-blocking structure 32 is the same as the thickness of the black matrix 41.

[0073] In some embodiments, during the manufacturing of the display panel, a black matrix 41 is first fabricated, and a color resist unit 42 is fabricated after the fabrication process of the black matrix 41. The color resist unit 42 is located on the side of the black matrix 41 furthest from the substrate 10. In this embodiment of the invention, the color resist portion 43 includes the color resist unit 42, such as... Figure 9 As shown, the color resist part 43 is located on the side of the black matrix 41 away from the substrate 10. The color resist part 43, composed of color resist units 42, is stacked on the black matrix 41. The color resist part 43 and the black matrix 41 are stacked to form the first light-blocking structure 31, which has a large thickness. This makes the light-blocking ability of the first light-emitting device 21 greater than that of the second light-blocking structure 32 on the second light-emitting device 22. The first light-blocking structure 31 can reduce the amount of light emitted by the first light-emitting device 21 that can be directed towards the human eye. This can balance the brightness difference between the first display area AA1 and the second display area AA2 caused by different viewing angles, reduce the brightness difference received by the human eye when observing the two areas, improve the problem of uneven brightness in vision, and enhance the visual effect.

[0074] In some embodiments, Figure 11 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 1As shown, the light emitted from the end of the first light-emitting device 21 near its adjacent first light-blocking structure 31 that is not blocked by the color resist part 43 is light ray S1-2. The angle between light ray S1-2 and the direction looking directly at the first light-emitting device 21 is θ1, which is the critical emission angle of the first light-emitting device 21. In other words, the color resist part 43 corresponds to the critical emission angle θ1 of the first light-emitting device 21. The light emitted from the end of the first light-emitting device 21 near its adjacent first light-blocking structure 31 that is not blocked by the black matrix 41 is light ray S1-3, which is the angle between light ray S1-3 and the direction looking directly at the first light-emitting device 21 is θ0. θ0 is the first critical emission angle of the first light-emitting device 21 (the first critical emission angle is not the actual critical emission angle). In other words, the black matrix 41 corresponds to the first critical emission angle θ0 of the first light-emitting device 21. Both θ1 and θ0 satisfy θ1 < θ0. In this embodiment, the color resist part 43 is located on the side of the black matrix 41 away from the substrate 10. After the color resist part 43 and the black matrix 41 are stacked, the thickness of the first light-blocking structure 31 is large. The color resist part 43 can block the light emitted by the first light-emitting device 21, thereby using the color resist part 43 to limit the critical emission angle θ1 of the first light-emitting device 21.

[0075] In addition, such as Figure 11 The color resist portion 43 shown has a certain width D, which is the width of the first stacked structure composed of color resist units 42 of at least two colors, and the overlap width of the color resist units 42 stacked together in the cross-sectional view. The width D of the color resist portion 43 affects the critical emission angle θ1 of the first light-emitting device 21. In some embodiments, the width D of the color resist portion 43 gradually decreases in the direction from the first display area AA1 to the second display area AA2, thereby enabling a gradual adjustment of the critical emission angle of the first light-emitting device 21. This results in a gradual decrease in the light-blocking ability of the first light-blocking structure 31 on the first light-emitting device 21 in the direction from the first display area AA1 to the second display area AA2, achieving a gradual change in visual brightness from the first display area AA1 to the second display area AA2, thus improving the visual effect.

[0076] In some embodiments, the color resist unit 42 with the largest distance from the black matrix 41 among the color resist units 42 in the color resist section 43 is a red color resist unit or a blue color resist unit.

[0077] Figure 12 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 12As shown, at least a portion of the color resist section 43 in the display panel includes a first color resist unit 42-1, a second color resist unit 42-2, and a third color resist unit 42-3 stacked sequentially, wherein the third color resist unit 42-3 is the color resist unit with the largest distance from the black matrix 41. In one embodiment, the third color resist unit 42-3 is a red color resist unit, and one of the first color resist unit 42-1 and the second color resist unit 42-2 is a green color resist unit and the other is a blue color resist unit. In another embodiment, the third color resist unit 42-3 is a blue color resist unit, and one of the first color resist unit 42-1 and the second color resist unit 42-2 is a green color resist unit and the other is a red color resist unit. In this embodiment, the structure in which a portion of the color resist section 43 includes stacked color resist units of three colors can increase the thickness of the color resist section 43, thereby further increasing the thickness of the first light-blocking structure 31 and enhancing the light-blocking capability of the first light-blocking structure 31. In addition, by setting the color resist section 43 to include a structure in which color resist units of three colors are stacked, the color resist section 43 has a stronger light-blocking ability, which can help reduce the reflectivity of the display panel.

[0078] In another embodiment, Figure 13 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 13 As shown, the color resist layer 40 is located on the side of the light-emitting device layer 20 away from the substrate 10. The color resist layer 40 includes a black matrix 41 and a plurality of color resist units 42; the color resist unit 42 includes at least three color resist units with different colors supplied. Figure 13Only the first color resist unit 42-1 and the second color resist unit 42-2, which have different colors, are shown in the diagram. The black matrix 41 includes a cutout, and the cutout of the black matrix 41 overlaps with the light-emitting device in the film layer stacking direction of the display panel. In the film layer stacking direction of the display panel, the color resist unit 42 overlaps with the cutout of the black matrix 41, and at least a portion of the color resist unit 42 overlaps with the light-emitting device. The black matrix 41 has light-blocking properties, and the color resist unit 42 has light-filtering properties. The light-filtering characteristics of the color resist unit 42 can reduce the reflection of ambient light by the display panel and improve the display effect. Both the first light-blocking structure 31 and the second light-blocking structure 32 include the black matrix 41; the thickness of the black matrix 41 in the first light-blocking structure 31 is greater than the thickness of the black matrix 41 in the second light-blocking structure 32. In this embodiment, the thickness of the black matrix 41 in the first display area AA1 is set to be greater than the thickness of the black matrix 41 in the second display area AA2, thus reusing the black matrix 41 as a light-blocking structure. The greater the thickness of the black matrix 41, the stronger its light-blocking ability. This makes the light-blocking ability of the first light-blocking structure 31 on the first light-emitting device 21 greater than that of the second light-blocking structure 32 on the second light-emitting device 22. The first light-blocking structure 31 reduces the amount of light emitted by the first light-emitting device 21 that can be directed toward the human eye. This balances the brightness difference between the first display area AA1 and the second display area AA2 caused by different viewing angles, reducing the brightness difference received by the human eye when observing the two areas, improving the problem of uneven brightness in vision, and enhancing the visual effect.

[0079] In another embodiment, Figure 14 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 14 As shown, the color resist layer 40 is located on the side of the light-emitting device layer 20 away from the substrate 10. The color resist layer 40 includes a black matrix 41 and color resist units 42. The black matrix 41 includes cutouts, and in the film layer stacking direction of the display panel, the cutouts of the black matrix 41 overlap with the light-emitting device. In the film layer stacking direction of the display panel, the color resist units 42 overlap with the cutouts of the black matrix 41, and at least a portion of the color resist units 42 overlaps with the light-emitting device. The black matrix 41 has light-shielding properties, and the color resist units 42 have light-filtering properties. Utilizing the light-filtering characteristics of the color resist units 42 can reduce the reflection of ambient light by the display panel and improve the display effect. Both the first light-blocking structure 31 and the second light-blocking structure 32 include a black matrix 41; the height of the black matrix 41 in the first light-blocking structure 31 is higher than the height of the black matrix 41 in the second light-blocking structure 32. When comparing the height of the black matrix 41, a common reference plane in the film layers of the display panel is used for comparison. Figure 14The diagram illustrates that the vertical distance from the surface of the black matrix 41 in the first light-blocking structure 31 away from the substrate 10 is the height h3 of the black matrix 41, and the vertical distance from the surface of the black matrix 41 in the second light-blocking structure 32 away from the substrate 10 is the height h4 of the black matrix 41. Where h3 is greater than h4. The height of the black matrix 41 in the first display area AA1 is set to be greater than the height of the black matrix 41 in the second display area AA2, thus reusing the black matrix 41 as a light-blocking structure. The higher the height of the black matrix 41, the stronger its light-blocking ability, thereby increasing the light-blocking ability of the first light-blocking structure 31 on the first light-emitting device 21. The first light-blocking structure 31 reduces the amount of light emitted by the first light-emitting device 21 that can be directed towards the human eye, thereby balancing the brightness difference between the first display area AA1 and the second display area AA2 caused by different viewing angles. This reduces the brightness difference received by the human eye when observing the two areas, improving the problem of uneven visual brightness and enhancing the visual effect.

[0080] like Figure 14 As shown, the film layer containing the color resist unit 42 is located on the side of the film layer containing the black matrix 41 closer to the substrate 10, and the first light-blocking structure 31 overlaps with the color resist unit 42; there is a gap between two color resist units 42 adjacent to the second light-blocking structure 32, and the second light-blocking structure 32 is located in the gap. In the manufacturing process of the display panel provided by this embodiment, the color resist unit 42 is first manufactured, and then the black matrix 41 is manufactured after the color resist unit 42 process. By setting both the first light-blocking structure 31 and the second light-blocking structure 32 to include the black matrix 41, and the first light-blocking structure 31 overlaps with the color resist unit 42, the black matrix 41 can be raised using the color resist unit 42, so that the height of the first light-blocking structure 31 is higher than the height of the second light-blocking structure 32. This ensures that the light-blocking capability of the first light-emitting device 21 by the first light-blocking structure 31 is greater than the light-blocking capability of the second light-emitting device 22 by the second light-blocking structure 32.

[0081] Color resist unit 42 includes at least three colors of color resist units. Figure 14 The diagram illustrates a first color resist unit 42-1 and a second color resist unit 42-2 of different colors. The edges of adjacent first color resist units 42-1 and second color resist units 42-2 are in contact, and a black matrix 41 is stacked on top of the contacting first color resist units 42-1 and second color resist units 42-2 to increase the height of the black matrix 41, so as to use the black matrix 41 as a first light-blocking structure 31.

[0082] In another embodiment, at least two color blocking units 42 stacked on top of each other are disposed below the first light-blocking structure 31. Figure 15 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 15As shown, at the position of the first light-blocking structure 31, the edges of the first color resist unit 42-1 and the second color resist unit 42-2 overlap with each other. The black matrix 41 on the overlapping first color resist unit 42-1 and the second color resist unit 42-2 is reused as the first light-blocking structure 31. This arrangement makes the height of the first light-blocking structure 31 higher, which can increase the light-blocking ability of the first light-emitting device 21.

[0083] In another embodiment, Figure 16 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 16 As shown, the black matrix 41 is located on the side of the film layer containing the color resist unit 42 away from the substrate 10. Both the first light-blocking structure 31 and the second light-blocking structure 32 include the black matrix 41. At the location of the black matrix 41 in the first light-blocking structure 31, the edges of the first color resist unit 42-1 and the second color resist unit 42-2 overlap each other; at the location of the black matrix 42 in the second light-blocking structure 32, the edges of the first color resist unit 42-1 and the second color resist unit 42-2 are in contact with each other. This arrangement makes the height of the first light-blocking structure 31 higher than the height of the second light structure 32, thereby increasing the light-blocking capability of the first light-emitting device 21.

[0084] In some embodiments, the black matrix 41 is located on the side of the color resist unit 40 away from the substrate 10. The first light-blocking structure 31 includes the black matrix 41, and the black matrix 41 is raised within the first display area AA1 using the color resist unit 40 to serve as the first light-blocking structure 31. In one embodiment, the thickness of the portion of the color resist unit 40 overlapping with the black matrix 41 within the first display area AA1 is set to be less than the thickness of the portion of the color resist unit 40 overlapping with the first light-emitting device 21. This setting raises the first light-blocking structure 31 using the color resist unit 40, increasing the height of the first light-blocking structure 31 and thus increasing its light-blocking capability. Reducing the thickness of the portion of the color resist unit 40 overlapping with the black matrix 41 within the first display area AA also ensures that the height of the first light-blocking structure 31 is not much higher than the height of the second light-blocking structure 32, which is beneficial to the flatness of the film layer.

[0085] In another embodiment, the thickness of the black matrix 41 within the first display area AA1 is set to be less than the thickness of the black matrix 41 within the second display area AA2. This configuration uses the color resist unit 40 to elevate the first light-blocking structure 31, increasing its height and thus its light-blocking capability. Furthermore, reducing the thickness of the black matrix 41 within the first display area AA ensures that the height of the first light-blocking structure 31 is not significantly greater than the height of the second light-blocking structure 32, which is beneficial for the flatness of the film layer.

[0086] In another embodiment,Figure 17 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 17 As shown, in the region where the first light-blocking structure 31 is located, the color resist unit 42 has a first surface M1 and a first side surface M2. The first surface M1 is the surface of the color resist unit 42 away from the substrate 10. The first side surface M2 is connected to the first surface M1, and an angle is formed between the first surface M1 and the first side surface M2, that is, the first surface M1 and the first side surface M2 are not on the same horizontal plane. The first light-blocking structure 31 covers at least a portion of the first surface M1 and at least a portion of the first side surface M2. In the manufacturing process of the display panel provided in this embodiment, the color resist unit 42 is first manufactured, and then the black matrix 41 is manufactured after the process of the color resist unit 42. Within the first display area AA1, the edges of adjacent color resist units 42 overlap each other. A black matrix 41 is fabricated on the overlapping color resist units 42, which can raise the height of the black matrix 41. The raised black matrix 41 is used as the first light-blocking structure 31. The black matrix 41 covering the first surface M1 plays the role of adjusting the critical emission angle of the adjacent first light-emitting device 21, thereby reducing the amount of light emitted by the first light-emitting device 21 by using the first light-blocking structure 31, and balancing the brightness difference between the first display area AA1 and the second display area AA2 caused by different viewing angles.

[0087] Figure 17 In this embodiment, the structure formed by the overlapping edges of adjacent color blocking units 42 can be called a pad. The function of the pad is to increase the height of the black matrix 41 above it. The pad has a certain width D1. The width D1 of the pad affects the width of the portion of the black matrix 41 covering the first surface M1. Therefore, by adjusting the size of the width D1 of the pad, the width of the black matrix 41 covering the first surface M1 can be adjusted, thereby adjusting the light blocking capability of the first light blocking structure 31.

[0088] In some embodiments, Figure 18 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 18As shown, the display area AA also includes a transition display area AAG, which is located between the first display area AA1 and the second display area AA2. The light-emitting devices in the display layer 20 also include a third light-emitting device 23 located in the transition display area AAG. It can be understood that the third light-emitting device 23 is simply named according to its location within the display area; the third light-emitting device 23 includes red, green, and blue light-emitting devices. The light-blocking structure 30 also includes a third light-blocking structure 33, which is disposed adjacent to the third light-emitting device 23 and is used to block the light emitted by the third light-emitting device 23. In this embodiment of the invention, a transition display area AAG is provided between the first display area AA1 and the second display area AA2, and a third light-blocking structure 33 is provided within the transition display area AAG to adjust the light emitted by the third light-emitting device 23. The thickness of the first light-blocking structure 31 is greater than the thickness of the third light-blocking structure 33, and the thickness of the third light-blocking structure 33 is greater than the thickness of the second light-blocking structure 32; or the height of the first light-blocking structure 31 is greater than the height of the third light-blocking structure 33, and the height of the third light-blocking structure 33 is greater than the height of the second light-blocking structure 32. This ensures that the light-blocking capability of the first light-blocking structure 31 is greater than that of the third light-blocking structure 33, and the light-blocking capability of the third light-blocking structure 33 is greater than that of the second light-blocking structure 32. Consequently, the reduction in the emitted light amount of the first light-emitting device 21 is greater than the reduction in the emitted light amount of the third light-emitting device 23, and the reduction in the emitted light amount of the third light-emitting device 23 is greater than the reduction in the emitted light amount of the second light-emitting device. In other words, from the first display area AA1 to the transition display area AAG and then to the second display area AA2, the light-blocking structure 30 gradually reduces the light-blocking degree of the light-emitting device, thereby reducing the brightness difference caused by different viewing angles when observing different display areas. This allows the human eye to perceive a gradual transition in brightness from the first display area AA1 to the transition display area AAG and then to the second display area AA2 when viewing the display panel, improving the problem of uneven brightness and enhancing the visual effect.

[0089] In some embodiments, such as Figure 18 As shown, the critical emission angle of the first light-emitting device 21 is θ1, the critical emission angle of the second light-emitting device 22 is θ2, and the critical emission angle of the third light-emitting device 23 is θ3. The definition of the critical emission angle can be found in the description of the relevant embodiments above, and will not be repeated here. Wherein, θ1 < θ3 < θ2. This arrangement enables the emitted light amount of the first light-emitting device 21, the third light-emitting device 23, and the second light-emitting device 22 to gradually increase, balancing the brightness differences in different display areas caused by different viewing angles. This allows the human eye to perceive a gradual transition in brightness from the first display area AA1 to the transition display area AAG and then to the second display area AA2 when viewing the display panel, improving the problem of uneven brightness and enhancing the visual effect.

[0090] In some embodiments, Figure 19 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 19 As shown, the display panel includes a color resist layer 40 located on the side of the light-emitting device layer 20 away from the substrate 10. The color resist layer 40 includes a black matrix 41 and a plurality of color resist units 42. The color resist units 42 include a first color resist unit 42-1, a second color resist unit 42-2, and a third color resist unit 42-3, each with a different color. The film layer containing the color resist units 42 is located on the side of the film layer containing the black matrix 41 away from the substrate 10. During fabrication, the color resist units 42 are fabricated after the process of the black matrix 41. The first light-blocking structure 31 includes the black matrix 41 and a first color resist portion 43-1, which is a stacked structure composed of three colors of color resist units 42; the third light-blocking structure 33 includes the black matrix 41 and a second color resist portion 43-2, which is a stacked structure of two colors of color resist units 42; the second light-blocking structure 32 includes the black matrix 41. This configuration allows the thickness of the first light-blocking structure 31 to be greater than the thickness of the third light-blocking structure 33, and the thickness of the third light-blocking structure 33 to be greater than the thickness of the second light-blocking structure 32. Since the thicknesses of the light-blocking structures 30 differ, the light-blocking capabilities of each light-blocking structure 30 are different. This embodiment ensures that the light-blocking capability of the first light-blocking structure 31 is greater than that of the third light-blocking structure 33, and the light-blocking capability of the third light-blocking structure 33 is greater than that of the second light-blocking structure 32. Therefore, the reduction in the emitted light amount of the first light-emitting device 21 is greater than the reduction in the emitted light amount of the third light-emitting device 23, and the reduction in the emitted light amount of the third light-emitting device 23 is greater than the reduction in the emitted light amount of the second light-emitting device. From the first display area AA1 to the transition display area AAG and then to the second display area AA2, the light-blocking structure 30 gradually reduces the light-blocking degree of the light-emitting device, thereby reducing the brightness difference caused by different viewing angles when observing different display areas. This allows the human eye to perceive a gradual transition in brightness from the first display area AA1 to the transition display area AAG and then to the second display area AA2 when viewing the display panel, improving the problem of uneven brightness and enhancing the visual effect.

[0091] In some embodiments, Figure 20 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 20 As shown, both the first light-blocking structure 31 and the third light-blocking structure 33 include a stacked structure composed of a black matrix 41 and color resist units 42 of at least two colors. Figure 20The diagram illustrates that both the first light-blocking structure 31 and the third light-blocking structure 33 include a second color-blocking section 43-2 composed of overlapping color-blocking units 42 of two colors; the second light-blocking structure 32 includes a black matrix 41. The width of the overlapping area of ​​each color-blocking unit 42 in the first light-blocking structure 31 is D2, and the width of the overlapping area of ​​each color-blocking unit 42 in the third light-blocking structure 33 is D3, wherein D2 is greater than D3. The width of the overlapping area of ​​the color-blocking units 42 affects the distance between the light-emitting device and the overlapping area in the horizontal direction; wherein, in the planar area of ​​the display panel, the horizontal direction is the direction parallel to the plane where the substrate 10 is located; in the curved area of ​​the display panel, the horizontal direction can be considered as the direction parallel to the plane where the light-emitting device is located.

[0092] In this embodiment of the invention, color resist portions are stacked on top of a black matrix 41. Each color resist portion is formed by overlapping color resist units 42 of at least two colors, and the width of the color resist portion is the width of the overlapping area of ​​the color resist units in the light-blocking structure. Since the color resist portion functions as a light blocker, and it is located on the side of the black matrix 41 furthest from the substrate 10, the width of the color resist portion has a significant impact on the light-blocking capability of the light-blocking structure 30, which includes both the color resist portion and the black matrix. When the thickness of the color resist portion is essentially the same, the light-blocking capability of the light-blocking structure can be adjusted by changing the width of the color resist portion. In this embodiment, both the first light-blocking structure 31 and the third light-blocking structure 33 are stacked structures consisting of a black matrix 41 and color-blocking units 42 of at least two colors. This allows the thickness of both the first light-blocking structure 31 and the third light-blocking structure 33 to be greater than the thickness of the second light-blocking structure 32. When the difference in thickness between the first light-blocking structure 31 and the third light-blocking structure 33 is not significant, the width of the overlapping area of ​​each color-blocking unit 42 in the first light-blocking structure 31 is further set to be greater than the width of the overlapping area of ​​each color-blocking unit 42 in the third light-blocking structure 33. This allows the light-blocking capability of the first light-blocking structure 31 to be greater than that of the third light-blocking structure 33. In this embodiment, the light-blocking capability of the first light-blocking structure 31 is greater than that of the third light-blocking structure 33, and the light-blocking capability of the third light-blocking structure 33 is greater than that of the second light-blocking structure 32. It can achieve a gradual reduction in the light-blocking degree of the light-emitting device by using the light-blocking structure 30 to transition from the first display area AA1 to the transition display area AAG and then to the second display area AA2. This reduces the brightness difference caused by different viewing angles when observing different display areas, so that when viewing the display panel, the human eye can perceive a gradual transition in brightness from the first display area AA1 to the transition display area AAG and then to the second display area AA2.

[0093] In some embodiments, Figure 21 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 21As shown, the film layer containing the color resist unit 42 is located on the side of the film layer containing the black matrix 41 closer to the substrate 10; the color resist unit 42 includes at least three different color resist units. Figure 21 Only the first color resist unit 42-1 and the second color resist unit 42-2, which have different colors, are shown in the diagram. During the manufacturing of the display panel, a black matrix 41 is fabricated after the color resist unit 42. The light-blocking structure 30 includes the black matrix 41; wherein the first light-blocking structure 31 overlaps with the color resist unit 42; there are gaps between the color resist units 42 adjacent to the second light-blocking structure 32, and the second light-blocking structure 32 is located within the gaps; there are gaps between the color resist units 42 adjacent to the third light-blocking structure 33, and the third light-blocking structure 33 includes the portion located in the gap and the portion covering the color resist unit 42. This arrangement allows the height of the first light-blocking structure 31 to be higher than the height of the third light-blocking structure 33, and the height of the third light-blocking structure 33 to be higher than the height of the second light-blocking structure 32. By setting light-blocking structures with different heights, the light-blocking ability of each light-blocking structure is adjusted, so that the light-blocking ability of the first light-blocking structure 31 is greater than the light-blocking ability of the third light-blocking structure 33, and the light-blocking ability of the third light-blocking structure 33 is greater than the light-blocking ability of the second light-blocking structure 32. It can achieve a gradual reduction in the light-blocking degree of the light-emitting device by using the light-blocking structure 30 to transition from the first display area AA1 to the transition display area AAG and then to the second display area AA2. This reduces the brightness difference caused by different viewing angles when observing different display areas, so that when viewing the display panel, the human eye can perceive a gradual transition in brightness from the first display area AA1 to the transition display area AAG and then to the second display area AA2.

[0094] In some embodiments, Figure 22 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 22 As shown, the film layer containing the color resist unit 42 is located on the side of the film layer containing the black matrix 41 closer to the substrate 10; the light-blocking structure 30 includes the black matrix 41; wherein, both the first light-blocking structure 31 and the third light-blocking structure 33 overlap with the color resist unit 42; the width of the first light-blocking structure 31 is greater than the width of the third light-blocking structure 33. That is, the width of the black matrix 41 in the first light-blocking structure 31 is greater than the width of the black matrix 41 in the third light-blocking structure 33. In this embodiment, the height difference between the first light-blocking structure 31 and the third light-blocking structure 33 is not significant, or their heights are basically the same. By setting the widths of the first light-blocking structure 31 and the third light-blocking structure 33 to be different, the light-blocking ability of the first light-blocking structure 31 is greater than that of the third light-blocking structure 33.

[0095] In some embodiments, Figure 23 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 23As shown, the first light-emitting device 21 includes a first-color first light-emitting device 21-1; the second light-emitting device 22 includes a first-color second light-emitting device 22-1; the light-emitting color of the first-color first light-emitting device 21-1 and the light-emitting color of the first-color second light-emitting device 22-1 are the same; wherein, the critical emission angle of the first-color first light-emitting device 21-1 is θ1, and the critical emission angle of the first-color second light-emitting device 22-1 is θ2. That is to say, for light-emitting devices of the same color, the critical emission angle of the light-emitting device in the first display area AA1 is smaller than the critical emission angle of the light-emitting device in the second display area AA. The light-emitting colors of the first-color first light-emitting device 21-1 and the first-color second light-emitting device 22-1 are any one of red, green, and blue.

[0096] Based on the same inventive concept, this invention also provides another display panel. Figure 24 This is another schematic diagram of a display panel provided in an embodiment of the present invention, such as... Figure 24 As shown, the display panel includes a display area AA and a non-display area NA. The display area AA includes a first display area AA1 and a second display area AA2, with the second display area AA2 located between the first display area AA1 and the non-display area NA. The display panel includes a substrate 10, a light-emitting device layer 20, and a light-blocking structure 30.

[0097] The light-emitting device layer 20 is located on one side of the substrate 10. The light-emitting device layer 20 includes a plurality of light-emitting devices, including a first light-emitting device 21 and a second light-emitting device 22. The first light-emitting device 21 is located in the first display area AA1, and the second light-emitting device 22 is located in the second display area AA2.

[0098] The light-blocking structure 30 is located on the side of the light-emitting device layer 20 away from the substrate 10. The light-blocking structure 30 includes a first light-blocking structure 31 and a second light-blocking structure 32. The first light-blocking structure 31 is disposed adjacent to the first light-emitting device 21, and the second light-blocking structure 32 is disposed adjacent to the second light-emitting device 22.

[0099] The color resist layer 40 is located on the side of the light-emitting device layer 20 away from the substrate 10. The color resist layer 40 includes a black matrix 41 and a plurality of color resist units 42. The film layer containing the color resist units 42 is located on the side of the black matrix 41 away from the substrate 10. The color resist unit 42 includes at least three different colors. Figure 21 Only the first color resist unit 42-1 and the second color resist unit 42-2, which have different colors, are shown in the diagram.

[0100] The light-blocking structure 30 includes a black matrix 41 and a color resist section 43. The color resist section 43 includes a stacked structure composed of color resist units 42 of at least two colors. The width of the overlapping area of ​​each color resist unit 42 in the color resist section 43 is the width of the color resist section 43. Figure 24The diagram illustrates the overlapping of the edges of the first color resist unit 42-1 and the second color resist unit 42-2 to form a color resist portion 43. The width of the color resist portion 43 in the first light-blocking structure 31 is D4, and the width of the color resist portion 43 in the second light-blocking structure 32 is D5. Wherein, D4 is greater than D5.

[0101] In this embodiment of the invention, a color resist portion 43 is stacked on top of a black matrix 41, and the color resist portion 43 is formed by overlapping color resist units 42 of at least two colors. The color resist portion 43 can block light. Since the color resist portion 43 is located on the side of the black matrix 41 away from the substrate 10, in the light-blocking structure 30 including the color resist portion 43 and the black matrix 41, the width of the color resist portion 43 has a significant impact on the light-blocking capability of the light-blocking structure 30. When the thickness of the color resist portion 43 is basically the same, the light-blocking capability of the light-blocking structure can be adjusted by adjusting the width of the color resist portion 43. In this embodiment, both the first light-blocking structure 31 and the second light-blocking structure 32 are stacked structures consisting of a black matrix 41 and color resist units 42 of at least two colors. Therefore, the thicknesses of the first light-blocking structure 31 and the second light-blocking structure 32 are not significantly different. In this case, the width of the color resist portion 43 in the first light-blocking structure 31 is greater than the width of the color resist portion 43 in the second light-blocking structure 32, making the light-blocking capability of the first light-blocking structure 31 greater than that of the second light-blocking structure 32. The first light-blocking structure 31 reduces the amount of light emitted by the first light-emitting device 21 that can be directed towards the human eye, thereby balancing the brightness difference between the first display area AA1 and the second display area AA2 caused by different viewing angles. This reduces the brightness difference received by the human eye when observing the two areas, improving the problem of uneven visual brightness and enhancing the visual effect.
