Description

Technical Field

[0001] This application belongs to the field of display technology, and particularly relates to a display panel and display device. Background Technology

[0002] With the continuous development of technology, the application scenarios of display panels are becoming increasingly widespread. Display panels are commonly used in devices such as mobile phones, computers, televisions, and wearable devices. In related technologies, to reduce the manufacturing difficulty and cost of display panels, and to thin them, the structural design of display panels still needs further improvement. Summary of the Invention

[0003] This application provides a display panel and a display device.

[0004] In a first aspect, embodiments of this application provide a display panel, comprising: a substrate; a pixel layer disposed on one side of the substrate, the pixel layer including a plurality of pixel units, each pixel unit including at least two sub-pixels with different colors; a color resist layer including at least two sub-color resist layers with different colors, the at least two sub-color resist layers being stacked on the side of the pixel layer away from the substrate, each sub-color resist layer including a light-transmitting opening and a color resist portion distributed around the light-transmitting opening, the light-transmitting opening of the sub-color resist layer being located on the side of the sub-pixel with a different color away from the substrate, the color resist portion including a filter portion and a functional portion disposed around the filter portion, the filter portion being located on the side of the sub-pixel with the same color away from the substrate, the functional portions of at least two sub-color resist layers with different colors being stacked to form a light-blocking structure, in two adjacent sub-color resist layers, the filter portion of the sub-color resist layer away from the substrate is located within the light-transmitting opening of the sub-color resist layer close to the substrate, and the refractive index of the sub-color resist layer close to the substrate is less than the refractive index of the sub-color resist layer away from the substrate.

[0005] Secondly, embodiments of this application provide a display device, which includes a display panel as described in the first aspect embodiment above.

[0006] An embodiment of this application provides a display panel including a substrate, a pixel layer, and a color resist layer. The pixel layer includes multiple pixel units, and each pixel unit includes at least two sub-pixels with different colors. The sub-pixels can be used to emit light to realize the display function of the display panel.

[0007] The color resist layer includes at least two sub-color resist layers of different colors. The sub-color resist layers can be used to filter light, and the different colors of the sub-color resist layers can be used to allow different colors of light to pass through. Each sub-color resist layer includes a light-transmitting opening and color resist portions distributed around the light-transmitting opening. The light-transmitting opening of the sub-color resist layer is located on the side of the sub-pixel that is different in color from itself and faces away from the substrate, so that the sub-color resist layer does not easily block the light emitted by the sub-pixel that is different in color from itself.

[0008] The color resist layer includes a filter sub-layer and functional sub-layers surrounding the filter sub-layer. The filter sub-layer is located on the side of the sub-pixel that is the same color as itself, facing away from the substrate, so that the filter sub-layer can be used to allow light emitted by the sub-pixel that is the same color as itself to pass through. At least two functional sub-layers of different colors of color resist are stacked to form a light blocking structure. Since the functional sub-layers participating in the formation of the light blocking structure are different colors, the light blocking structure has good light blocking ability and can be used to block stray light from escaping from the display panel.

[0009] In two adjacent sub-color resist layers, the filter portion of the sub-color resist layer farther from the substrate is located within the light-transmitting opening of the sub-color resist layer closer to the substrate. The refractive index of the sub-color resist layer closer to the substrate is less than that of the sub-color resist layer farther from the substrate. This allows a total internal reflection interface to be formed between the filter portion of the sub-color resist layer farther from the substrate and the sidewall of the light-transmitting opening of the sub-color resist layer closer to the substrate. This total internal reflection interface can be used to reflect light emitted from the sub-pixel at a large tilt angle, allowing more light to be emitted from the direction perpendicular to the plane of the substrate, thereby improving the forward light emission brightness of the display panel.

[0010] Since the color resist layer provided in this application embodiment can serve as a color resist structure for filtering light, a black matrix structure for blocking light, and a microlens structure for adjusting the light emission angle of sub-pixels, it eliminates the need to separately fabricate the color resist structure, black matrix structure, and microlens structure during the fabrication of the display panel. This reduces the fabrication steps of the display panel, significantly increases the fabrication difficulty of the display panel, reduces the fabrication cost of the display panel, and also significantly reduces the thickness of the display panel.

Detailed Implementation

[0014] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are intended only to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0017] With the continuous development of technology, the application scenarios of display panels are becoming increasingly widespread. Display panels are commonly used in devices such as mobile phones, computers, televisions, and wearable devices. In related technologies, to reduce the manufacturing difficulty and cost of display panels, and to thin them, the structural design of display panels still needs further improvement.

[0018] For example, in related technologies, in order to improve the display effect of the display panel, a layered color filter (CF) structure and a microlens panel (MLP) structure are often set in the display panel. Figure 1 This is a schematic diagram of the structure of a display panel as an example in related technologies, such as... Figure 1 As shown in the attached figures (the dashed arrows in the figures indicate the direction of light propagation), the color resist structure (CF) can be placed on the light-emitting side of the sub-pixels in the display panel. A black matrix (BM) structure is often placed around the CF. The BM can block stray light in the display panel, and the CF acts as a filter. Compared to a traditional polarizer (POL), the CF has higher light transmittance and improves the light emission effect of the display panel while reducing its power consumption. A microlens structure (MLP) can be placed above the color resist structure. The MLP can adjust the light emission angle of the light passing through the CF by utilizing the total internal reflection interface formed between the high-refractive-index material (HS) and the low-refractive-index material (LS), thereby improving the light emission from the forward viewing angle of the display panel, enhancing its light emission effect, and reducing its power consumption.

[0019] Based on the structure of display panels in related technologies, since the color resist structure (CF) and the microlens structure (MLP) are independent structures, it is impossible to efficiently and simultaneously fabricate the CF and MLP during the same process. Furthermore, the fabrication processes for the CF and MLP are complex, resulting in low fabrication efficiency and high costs. In addition, the CF and MLP are stacked, which hinders the reduction of display panel thickness.

[0020] To address the aforementioned technical problems, this application is provided. To better understand this application, the display panel and display device of embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] Figure 2 This is a schematic diagram of the structure of a display panel 10 provided in an embodiment of this application. Figure 3 This is a schematic diagram of the sub-pixel arrangement provided in an embodiment of this application. Figure 4 This is a partial cross-sectional view of a display panel 10 provided in an embodiment of this application. In the figure, the X direction can represent a first direction, the Y direction can represent a second direction, and the Z direction can represent a third direction. The first direction X, the second direction Y, and the third direction Z can intersect each other; for example, the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other.

[0022] like Figures 2 to 4 As shown, this application embodiment provides a display panel 10, including: a substrate 100; a pixel layer 200 disposed on one side of the substrate 100, the pixel layer 200 including a plurality of pixel units 201, each pixel unit 201 including at least two sub-pixels with different colors; and a color resist layer 500 including at least two sub-color resist layers 510 with different colors, the at least two sub-color resist layers 510 being stacked on the side of the pixel layer 200 away from the substrate 100, each sub-color resist layer 510 including a light-transmitting opening 510a and color resist portions 510b distributed around the light-transmitting opening 510a, the light-transmitting opening 510a of the sub-color resist layer 510 being located on the side of the sub-pixel with a different color from itself away from the substrate 100. The color resist portion 510b includes a filter sub-portion 510ba and a functional sub-portion 510bb surrounding the filter sub-portion 510ba. The filter sub-portion 510ba is located on the side of the sub-pixel with the same color as itself that is away from the substrate 100. At least two sub-color resist layers 510 with different colors have their functional sub-portions 510bb stacked to form a light blocking structure 500a. In two adjacent sub-color resist layers 510, the filter sub-portion 510ba of the sub-color resist layer 510 away from the substrate 100 is located in the light-transmitting opening 510a of the sub-color resist layer 510 close to the substrate 100, and the refractive index of the sub-color resist layer 510 close to the substrate 100 is less than the refractive index of the sub-color resist layer 510 away from the substrate 100.

[0023] Optionally, the display panel 10 provided in this application embodiment can be configured in various ways. For example, the display panel 10 provided in this application embodiment can be a display panel 10 that operates based on the Organic Light Emitting Diode (OLED) display principle or a display panel 10 that operates based on the Light Emitting Diode (LED) display principle. For ease of description, the following embodiments will be described using the display panel 10 provided in this application embodiment that operates based on the Organic Light Emitting Diode display principle as an example.

[0024] like Figure 2As shown, optionally, the display panel 10 may have a display area AA and a non-display area NA surrounding the display area AA. The display panel 10 in the display area AA can be used for light-emitting display, and the display panel 10 in the non-display area NA can be used for arranging circuits or wiring.

[0025] An embodiment of this application provides a display panel 10 including a substrate 100, a pixel layer 200, and a color resist layer 500.

[0026] Optionally, the first direction X and the second direction Y can be parallel to the plane where the substrate 100 is located, and the third direction Z can be perpendicular to the plane where the substrate 100 is located.

[0027] like Figure 3 As shown, the pixel layer 200 includes a plurality of pixel units 201, each pixel unit 201 including at least two sub-pixels with different colors, and the sub-pixels can be used to emit light to realize the display operation of the display panel 10.

[0028] Optionally, the pixel unit 201 includes a first sub-pixel 201a and a second sub-pixel 201b of different colors to facilitate color display of the display panel 10. Optionally, the pixel unit 201 also includes a third sub-pixel 201c of different colors from both the first sub-pixel 201a and the second sub-pixel 201b to further enhance the color display effect of the display panel 10.

[0029] For example, a single pixel unit 201 may include at least one first sub-pixel 201a, at least one second sub-pixel 201b, and at least one third sub-pixel 201c. The colors of the first sub-pixel 201a, the second sub-pixel 201b, and the third sub-pixel 201c may be different from each other. That is, the light emission color when the first sub-pixel 201a is lit, the light emission color when the second sub-pixel 201b is lit, and the light emission color when the third sub-pixel 201c is lit may be different, so as to realize the color display of the display panel 10.

[0030] Optionally, among the first sub-pixel 201a, the second sub-pixel 201b, and the third sub-pixel 201c, one can emit red light when illuminated, another can emit green light when illuminated, and the last can emit blue light when illuminated. Figure 3 The example shown is that the first sub-pixel 201a emits blue light when lit, the second sub-pixel 201b emits green light when lit, and the third sub-pixel 201c emits red light when lit, but this application is not limited to this.

[0031] For example, the light emission color of the first sub-pixel 201a when it is lit can be red, the light emission color of the second sub-pixel 201b when it is lit can be green, and the light emission color of the third sub-pixel 201c when it is lit can be blue; or, the light emission color of the first sub-pixel 201a when it is lit can be red, the light emission color of the third sub-pixel 201c when it is lit can be green, and the light emission color of the second sub-pixel 201b when it is lit can be blue; or, the light emission color of the second sub-pixel 201b when it is lit can be red, the light emission color of the first sub-pixel 201a when it is lit can be green, and the light emission color of the third sub-pixel 201c when it is lit can be blue. Alternatively, the second sub-pixel 201b can be lit up in red, the third sub-pixel 201c can be lit up in green, and the first sub-pixel 201a can be lit up in blue; or, the third sub-pixel 201c can be lit up in red, the first sub-pixel 201a can be lit up in green, and the second sub-pixel 201b can be lit up in blue; or, the third sub-pixel 201c can be lit up in red, the second sub-pixel 201b can be lit up in green, and the first sub-pixel 201a can be lit up in blue.

[0032] Optionally, the pixel units 201 can be arranged in an array along the first direction X and the second direction Y, so that the display panel 10 can have better display uniformity. For example, the pixel units 201 can be arranged in rows along the first direction X, and the pixel units 201 can be arranged in columns along the second direction Y.

[0033] Optionally, this application does not limit the number of sub-pixels included in the pixel unit 201, nor the arrangement of each sub-pixel within the pixel unit 201. For example, the number of sub-pixels in the pixel unit 201 and the arrangement of each sub-pixel within the pixel unit 201 can be referred to... Figure 3 Configure as shown.

[0034] Optional, such as Figure 4 As shown, the pixel layer 200 may include an array layer 210, which may include multiple insulating layers 211 and multiple pixel circuits 212. The pixel circuits 212 may be arranged between adjacent insulating layers 211 or between the insulating layers 211 and the substrate 100.

[0035] Optionally, the pixel circuit 212 can be configured in various ways, such as 2T1C, 4T1C, 7T1C, 7T2C, 8T1C, 8T2C, etc. For example, the pixel circuit 212 may include a transistor 212a, a storage capacitor 212b, and connecting traces for connecting various devices. The transistor 212a may include a semiconductor 212aa, a gate 212ab, and source / drain electrodes 212ac. The storage capacitor 212b may include a first electrode 212ba and a second electrode 212bb.

[0036] Optionally, in the direction away from the substrate 100, the array layer 210 may include a first insulating layer 211a, a second insulating layer 211b, a third insulating layer 211c, and a fourth insulating layer 211d stacked sequentially. Semiconductor 212aa may be disposed between the first insulating layer 211a and the substrate 100. Gate 212ab and first electrode 212ba may be disposed between the second insulating layer 211b and the first insulating layer 211a. Second electrode 212bb may be disposed between the third insulating layer 211c and the second insulating layer 211b. Source and drain electrodes 212ac may be disposed between the fourth insulating layer 211d and the third insulating layer 211c.

[0037] Optionally, the pixel layer 200 may include a light-emitting unit 220, which may be disposed on the side of the array layer 210 facing away from the substrate 100. The light-emitting unit 220 may be connected to the pixel circuit 212, and a sub-pixel may include the light-emitting unit 220 and the pixel circuit 212 connected to each other. The pixel circuit 212 may be used to drive the light-emitting unit 220 to emit light, thereby realizing the emission of the sub-pixel. For example, a single light-emitting unit 220 may be electrically connected to a single pixel circuit 212 to form a single sub-pixel.

[0038] Optionally, in the direction away from the substrate 100, the light-emitting unit 220 may include a first electrode 221, a light-emitting layer 222, and a second electrode 223 stacked sequentially. The first electrode 221 and the second electrode 223 can serve as pixel electrodes of the display panel 10. One of the first electrode 221 and the second electrode 223 can serve as an anode, and the other as a cathode to drive the light-emitting layer 222 to emit light. This embodiment uses the first electrode 221 as the anode of the display panel 10 and the second electrode 223 as the cathode for illuminating the display panel 10. The pixel circuit 212 can be connected to the first electrode 221 to provide a driving current to the first electrode 221 to drive the light-emitting layer 222 to emit light.

[0039] Optionally, the light-emitting layer 222 may include a first common layer 222a, a second common layer 222c disposed on the side of the first common layer 222a facing away from the substrate 100, and a light-emitting structure 222b disposed between the first common layer 222a and the second common layer 222c. For example, the first common layer 222a may include at least a hole injection layer (HIL) and a hole transport layer (HTL), and the second common layer 222c may include at least an electron injection layer (EIL) and an electron transport layer (ETL).

[0040] Optionally, the second electrodes 223 of each sub-pixel can be electrically connected to each other, thereby facilitating control of the display panel 10. For example, the second electrodes 223 of each sub-pixel can be integrally formed. Optionally, the first common layer 222a of each sub-pixel can be integrally formed, and the second common layer 222c of each sub-pixel can be integrally formed, to facilitate the fabrication of the display panel 10.

[0041] Optionally, the materials of the light-emitting structures 222b of sub-pixels with different colors can be different. For example, the materials of the light-emitting structures 222b of the first sub-pixel 201a, the materials of the light-emitting structures 222b of the second sub-pixel 201b, and the materials of the light-emitting structures 222b of the third sub-pixel 201c can all be different, so as to achieve different light-emitting colors when the first sub-pixel 201a is lit, the light-emitting colors when the second sub-pixel 201b is lit, and the light-emitting colors when the third sub-pixel 201c is lit.

[0042] Optionally, the pixel layer 200 may also include a pixel definition layer 230, which is located on the side of the first electrode 221 away from the substrate 100. The pixel definition layer 230 encloses and forms a pixel opening 230a. The light-emitting layer 222 and the second electrode 223 are at least partially located within the pixel opening 230a. The pixel definition layer 230 can be used to divide the sub-pixels in the display panel 10.

[0043] Optionally, the first electrode 221 has a functional surface 221a that is exposed from the pixel opening 230a and connected to the light-emitting layer 222. The area where the light-emitting layer 222 contacts the functional surface 221a can be the main light-emitting area of ​​the light-emitting layer 222.

[0044] Optionally, the pixel definition layer 230 may be made of a transparent material or a light-absorbing material. When the pixel definition layer 230 is made of a light-absorbing material, it can be used to block metallic reflections in the underlying array layer 210, and it can also be used to block light emitted from sub-pixels at a large tilt angle, thereby better adjusting the light emission angle of the sub-pixels.

[0045] Optionally, light rays emitted by a subpixel with a large tilt angle can refer to light rays emitted by a subpixel with a large angle relative to the third direction Z.

[0046] Optionally, the display panel 10 may further include an encapsulation layer 300 disposed on the side of the pixel layer 200 facing away from the substrate 100. The encapsulation layer 300 can be used to encapsulate sub-pixels. For example, in the direction away from the substrate 100, the encapsulation layer 300 may include a first encapsulation layer 310, a second encapsulation layer 320, and a third encapsulation layer 330 stacked sequentially. The material of the first encapsulation layer 310 may include inorganic materials. The first encapsulation layer 310 can be prepared by chemical vapor deposition (CVD) to give it better encapsulation capabilities, thereby reducing the impact of moisture on the pixel layer 200. The material of the second encapsulation layer 320 may include organic materials. The second encapsulation layer 320 can be prepared using inkjet printing (IJP) technology, which allows the material of the second encapsulation layer 320 to have good flowability during the preparation of the display panel 10. This makes the surface of the second encapsulation layer 320 facing away from the substrate 100 relatively flat, facilitating the subsequent preparation of other devices on the encapsulation layer 300. The material of the third encapsulation layer 330 may include inorganic materials. The third encapsulation layer 330 can be prepared using chemical vapor deposition, giving the third encapsulation layer 330 good encapsulation capabilities.

[0047] Optionally, the color resist layer 500 can be positioned in various ways. As an example, the color resist layer 500 can be disposed between adjacent encapsulation layers 300 (not shown in the figure; for example, the color resist layer 500 can be disposed between the first encapsulation layer 310 and the second encapsulation layer 320; or, the color resist layer 500 can be disposed between the second encapsulation layer 320 and the third encapsulation layer 330); or, the color resist layer 500 can be disposed on the side of the encapsulation layer 300 facing away from the substrate 100 (for example, the color resist layer 500 can be disposed on the side of the third encapsulation layer 330 facing away from the substrate 100).

[0048] The color resist layer 500 includes at least two sub-color resist layers 510 of different colors. The sub-color resist layers 510 can be used to filter light, and the sub-color resist layers 510 of different colors can be used to allow light of different colors to pass through.

[0049] Optionally, the color of the sub-color blocking layer 510 may refer to the color of light that the sub-color blocking layer 510 allows to pass through. For example, the color blocking layer 500 may include a sub-color blocking layer 510 for allowing red light to pass through, which may also block the transmission of light of other color wavelengths besides red light; the color blocking layer 500 may include a sub-color blocking layer 510 for allowing green light to pass through, which may also block the transmission of light of other color wavelengths besides green light; the color blocking layer 500 may include a sub-color blocking layer 510 for allowing blue light to pass through, which may also block the transmission of light of other color wavelengths besides blue light.

[0050] Optionally, sub-color resist layers 510 of different colors can correspond to sub-pixels with different emission colors. For example, color resist layer 500 includes a first sub-color resist layer 511 and a second sub-color resist layer 512 stacked on the side of the first sub-color resist layer 511 facing away from the substrate 100. The first sub-color resist layer 511 has the same color as the first sub-pixel 201a, and the second sub-color resist layer 512 has the same color as the second sub-pixel 201b. In a further example, color resist layer 500 also includes a third sub-color resist layer 513 stacked on the side of the second sub-color resist layer 512 facing away from the substrate 100, and the third sub-color resist layer 513 has the same color as the third sub-pixel 201c.

[0051] Optionally, in some embodiments of this application, a certain sub-color resist layer 510 is the same color as a certain sub-pixel. This can mean that a certain sub-color resist layer 510 can be used to allow light emitted by a certain sub-pixel to pass through, and the sub-color resist layer 510 can be used to block the transmission of at least some other colors of light besides the color of the light emitted by this sub-pixel. For example, the first sub-color resist layer 511 is the same color as the first sub-pixel 201a, which means that the first sub-color resist layer 511 can be used to allow light emitted by the first sub-pixel 201a to pass through, and the first sub-color resist layer 511 can be used to block the transmission of at least some other colors of light besides the color of the light emitted by the first sub-pixel 201a; the second sub-color resist layer 512 is the same color as the second sub-pixel 201b, which means that the second sub-color resist layer 512 can be used to allow light emitted by the second sub-pixel 201b to pass through, and the second sub-color resist layer 512 can be used to block the transmission of at least some other colors of light besides the color of the light emitted by the second sub-pixel 201b; the third sub-color resist layer 513 is the same color as the third sub-pixel 201c, which means that the third sub-color resist layer 513 can be used to allow light emitted by the third sub-pixel 201c to pass through, and the third sub-color resist layer 513 can be used to block the transmission of at least some other colors of light besides the color of the light emitted by the third sub-pixel 201c.

[0052] Each sub-color resist layer 510 includes a light-transmitting opening 510a and a color resist portion 510b distributed around the light-transmitting opening 510a. The light-transmitting opening 510a of the sub-color resist layer 510 is located on the side of the sub-pixel that is different from its own color and away from the substrate 100, so that the sub-color resist layer 510 is less likely to block the light emitted by the sub-pixel that is different from its own color.

[0053] Optionally, in some embodiments of this application, a light-transmitting opening 510a located on the side of a sub-pixel facing away from the substrate 100 can mean that the light-transmitting opening 510a is located on the side of the light-emitting unit 220 of a sub-pixel facing away from the substrate 100. Further, a light-transmitting opening 510a located on the side of a sub-pixel facing away from the substrate 100 can mean that the light-transmitting opening 510a is located on the side of the functional surface 221a of a sub-pixel facing away from the substrate 100.

[0054] For example, at least a portion of the light-transmitting opening 510a of the first sub-color resist layer 511 is located on the side of the second sub-pixel 201b away from the substrate 100 (for example, the orthographic projection of at least a portion of the light-transmitting opening 510a of the first sub-color resist layer 511 on the substrate 100 may at least partially overlap with the orthographic projection of the functional surface 221a of the second sub-pixel 201b on the substrate 100); at least a portion of the light-transmitting opening 510a of the first sub-color resist layer 511 is located on the side of the third sub-pixel 201c away from the substrate 100 (for example, at least a portion of the light-transmitting opening 510a of the first sub-color resist layer 511 is located on the side of the third sub-pixel 201c away from the substrate 100). The orthographic projection of the light-transmitting opening 510a of layer 511 onto the substrate 100 can at least partially overlap with the orthographic projection of the functional surface 221a of the third sub-pixel 201c onto the substrate 100; at least a portion of the light-transmitting opening 510a of the second sub-color resist layer 512 is located on the side of the first sub-pixel 201a away from the substrate 100 (for example, the orthographic projection of the light-transmitting opening 510a of the second sub-color resist layer 512 onto the substrate 100 can at least partially overlap with the orthographic projection of the functional surface 221a of the first sub-pixel 201a onto the substrate 100). (overlap); at least a portion of the light-transmitting opening 510a of the second sub-color resist layer 512 is located on the side of the third sub-pixel 201c away from the substrate 100 (for example, the orthographic projection of the light-transmitting opening 510a of at least a portion of the second sub-color resist layer 512 on the substrate 100 may at least partially overlap with the orthographic projection of the functional surface 221a of the third sub-pixel 201c on the substrate 100); at least a portion of the light-transmitting opening 510a of the third sub-color resist layer 513 is located on the side of the first sub-pixel 201a away from the substrate 100 (for example, at least a portion of the third sub-color resist layer 512... The orthographic projection of the light-transmitting opening 510a of the third sub-color resist layer 513 onto the substrate 100 may at least partially overlap with the orthographic projection of the functional surface 221a of the first sub-pixel 201a onto the substrate 100; the light-transmitting opening 510a of at least a portion of the third sub-color resist layer 513 is located on the side of the second sub-pixel 201b away from the substrate 100 (for example, the orthographic projection of the light-transmitting opening 510a of at least a portion of the third sub-color resist layer 513 onto the substrate 100 may at least partially overlap with the orthographic projection of the functional surface 221a of the second sub-pixel 201b onto the substrate 100).

[0055] The color resist portion 510b includes a filter sub-portion 510ba and a functional sub-portion 510bb disposed around the filter sub-portion 510ba. The filter sub-portion 510ba is located on the side of the sub-pixel with the same color as itself that is away from the substrate 100, so that the filter sub-portion 510ba can be used to allow light emitted by the sub-pixel with the same color as itself to pass through.

[0056] For example, the filter portion 510ba of the first sub-color resist layer 511 may be located on the side of the first sub-pixel 201a away from the substrate 100; the filter portion 510ba of the second sub-color resist layer 512 may be located on the side of the second sub-pixel 201b away from the substrate 100; and the filter portion 510ba of the third sub-color resist layer 513 may be located on the side of the third sub-pixel 201c away from the substrate 100.

[0057] Optionally, in a color resist portion 510b of a certain sub-color resist layer 510, the portion that does not overlap with the color resist portions 510b of other sub-color resist layers 510 can be a filter sub-portion 510ba, and the portion that overlaps with other sub-color resist layers 510 can be a functional sub-portion 510bb.

[0058] At least two sub-color resist layers 510 of different colors are stacked to form a light blocking structure 500a. Since the functional sub-color resist layers 510bb of different colors participate in forming the light blocking structure 500a, the light blocking structure 500a has a good light blocking ability. The light blocking structure 500a can be used to block stray light from being emitted outward from the display panel 10.

[0059] Optionally, the number of functional sub-units 510bb included in the light-blocking structure 500a can be configured in various ways. As an example, such as... Figure 4 As shown, the light blocking structure 500a can be formed by stacking two functional sub-parts 510bb with different colors (for example, a portion of the light blocking structure 500a can be formed by stacking the functional sub-parts 510bb of the first sub-color resist layer 511 and the functional sub-parts 510bb of the second sub-color resist layer 512; a portion of the light blocking structure 500a can be formed by stacking the functional sub-parts 510bb of the first sub-color resist layer 511 and the functional sub-parts 510bb of the third sub-color resist layer 513; a portion of the light blocking structure 500a can be formed by stacking the functional sub-parts 510bb of the second sub-color resist layer 512 and the functional sub-parts 510bb of the third sub-color resist layer 513). Figure 5 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application. As another example, such as... Figure 5 As shown, the light blocking structure 500a can be formed by stacking at least three functional sub-parts 510bb of different colors (for example, the light blocking structure 500a can be formed by stacking the functional sub-parts 510bb of the first sub-color blocking layer 511, the functional sub-parts 510bb of the second sub-color blocking layer 512, and the functional sub-parts 510bb of the third sub-color blocking layer 513).

[0060] For ease of description, the following embodiments will be described using the example of "the light blocking structure 500a being formed by stacking the functional sub-parts 510bb of the first sub-color resist layer 511, the functional sub-parts 510bb of the second sub-color resist layer 512, and the functional sub-parts 510bb of the third sub-color resist layer 513".

[0061] Optionally, a single light-transmitting opening 510a in the sub-color resist layer 510 can be located above a single sub-pixel, that is, a single light-transmitting opening 510a in the sub-color resist layer 510 can be set corresponding to a single sub-pixel.

[0062] Optionally, a portion of the light-transmitting opening 510a of the first sub-color resist layer 511 is located on the side of the second sub-pixel 201b facing away from the substrate 100; a portion of the light-transmitting opening 510a of the third sub-color resist layer 513 is located on the side of the second sub-pixel 201b facing away from the substrate 100 and overlaps with the light-transmitting opening 510a of the first sub-color resist layer 511; a portion of the light-transmitting opening 510a of the first sub-color resist layer 511 is located on the side of the third sub-pixel 201c facing away from the substrate 100; a portion of the light-transmitting opening 510a of the second sub-color resist layer 513 is located on the side of the third sub-pixel 201c facing away from the substrate 100; and a portion of the light-transmitting opening 510a of the second sub-color resist layer 513 is located on the side of the third sub-pixel 201c facing away from the substrate 100. The light-transmitting opening 510a of the third sub-pixel 201c is located on the side away from the substrate 100 and overlaps with the light-transmitting opening 510a of the first sub-color resist layer 511; the light-transmitting opening 510a of a portion of the second sub-color resist layer 512 is located on the side away from the substrate 100 of the first sub-pixel 201a, and the light-transmitting opening 510a of a portion of the third sub-color resist layer 513 is located on the side away from the substrate 100 of the first sub-pixel 201a and overlaps with the light-transmitting opening 510a of the second sub-color resist layer 512.

[0063] Optionally, in some embodiments of this application, the overlap of one light-transmitting opening 510a with another light-transmitting opening 510a may refer to the fact that the orthographic projections of the two light-transmitting openings 510a on the substrate 100 may at least partially overlap.

[0064] In two adjacent sub-color resist layers 510, by setting the filter portion 510ba of the sub-color resist layer 510 away from the substrate 100 within the light-transmitting opening 510a of the sub-color resist layer 510 close to the substrate 100, and by setting the refractive index of the sub-color resist layer 510 close to the substrate 100 to be less than that of the sub-color resist layer 510 away from the substrate 100, a total internal reflection interface can be formed between the sidewall of the filter portion 510ba of the sub-color resist layer 510 further away from the substrate 100 and the sidewall of the light-transmitting opening 510a of the sub-color resist layer 510 closer to the substrate 100. This total internal reflection interface can be used to reflect light emitted from the sub-pixel with a large tilt angle, so that more light can be emitted outward from the direction perpendicular to the plane of the substrate 100, thereby improving the forward light emission brightness of the display panel 10.

[0065] For example, the filter portion 510ba of the second sub-color resist layer 512 is located in the light-transmitting opening 510a of the first sub-color resist layer 511 on the side of the second sub-pixel 201b away from the substrate 100. The refractive index of the second sub-color resist layer 512 is greater than that of the first sub-color resist layer 511, so that the light emitted by the second sub-pixel 201b can undergo total internal reflection on the side wall of the light-transmitting opening 510a of the first sub-color resist layer 511. This allows the light emitted by the second sub-pixel 201b to be concentrated into a larger amount of light emitted along the third direction Z, thereby improving the forward light emission brightness of the display panel 10.

[0066] Similarly, by way of example, the filter portion 510ba of the third sub-color resist layer 513 may be located within the light-transmitting opening 510a of the first sub-color resist layer 511 and the light-transmitting opening 510a of the second sub-color resist layer 512 on the side of the third sub-pixel 201c facing away from the substrate 100. When the refractive index of the third sub-color resist layer 513 is greater than the refractive index of the first sub-color resist layer 511, the light emitted by the third sub-pixel 201c can undergo total internal reflection at the sidewall of the light-transmitting opening 510a of the first sub-color resist layer 511; when the refractive index of the third sub-color resist layer 513 is greater than the refractive index of the second sub-color resist layer 512, the light emitted by the third sub-pixel 201c can undergo total internal reflection at the sidewall of the light-transmitting opening 510a of the second sub-color resist layer 512.

[0067] Optionally, in some embodiments of this application, a certain filter sub-section 510ba is located on the side of a sub-pixel facing away from the substrate 100. This can mean that the filter sub-section 510ba is located on the side of the light-emitting unit 220 of a sub-pixel facing away from the substrate 100. Further, the fact that a certain filter sub-section 510ba is located on the side of a sub-pixel facing away from the substrate 100 can mean that the filter sub-section 510ba is located on the side of the functional surface 221a of a sub-pixel facing away from the substrate 100.

[0068] Since the color resist layer 500 provided in this embodiment can serve as a color resist structure for filtering light, a black matrix structure for blocking light, and a microlens structure for adjusting the light emission angle of sub-pixels, it eliminates the need to separately fabricate the color resist structure, black matrix structure, and microlens structure during the fabrication of the display panel 10. This reduces the fabrication steps of the display panel 10, significantly increases the fabrication difficulty of the display panel 10, reduces the fabrication cost of the display panel 10, and also significantly reduces the thickness of the display panel 10.

[0069] Figure 6 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0070] like Figure 6As shown, optionally, the display panel 10 also includes an optically transparent adhesive layer 600 disposed on the side of the color resist layer 500 facing away from the substrate 100. The optically transparent adhesive layer 600 can be used to protect the color resist layer 500, and the optically transparent adhesive layer 600 has a small impact on blocking light passing through the color resist layer 500 below.

[0071] In some examples, a portion of the optically transparent adhesive layer 600 is located within the light-transmitting opening 510a, and the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the sub-color resist layer 510 surrounding the light-transmitting opening 510a where the optically transparent adhesive layer 600 is located. This allows a total internal reflection interface to be formed between the optically transparent adhesive layer 600 and the sidewall of the light-transmitting opening 510a around it, further reflecting the light emitted by the sub-pixels at a large tilt angle. This allows more light to be emitted from the direction perpendicular to the plane of the substrate 100, thereby improving the forward light emission brightness of the display panel 10.

[0072] For example, a portion of the optically transparent adhesive layer 600 is located within the light-transmitting opening 510a of the first sub-pixel 201a on the side opposite to the substrate 100 in the second sub-color resist layer 512. The refractive index of the optically transparent adhesive layer 600 is greater than that of the second sub-color resist layer 512, so that a total internal reflection interface can be formed between the optically transparent adhesive layer 600 and the sidewall of the light-transmitting opening 510a of the second sub-color resist layer 512, so that light emitted from the first sub-pixel 201a with a large tilt angle can be reflected.

[0073] Similarly, the relative positional relationship and refractive index relationship between the optically transparent adhesive layer 600 and the third sub-color resist layer 513 can be reasonably set so that a total internal reflection interface can be formed between the sidewall of the light-transmitting opening 510a of the optically transparent adhesive layer 600 and the third sub-color resist layer 513, thereby reflecting the light emitted by the first sub-pixel 201a or the second sub-pixel 201b with a large tilt angle. For example, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, and part of the optically transparent adhesive layer 600 is located in the light-transmitting opening 510a of the third sub-color resist layer 513 on the side of the first sub-pixel 201a facing away from the substrate 100; and / or, part of the optically transparent adhesive layer 600 is located in the light-transmitting opening 510a of the third sub-color resist layer 513 on the side of the second sub-pixel 201b facing away from the substrate 100.

[0074] For ease of description, the following embodiments will be described using the example that "part of the optically transparent adhesive layer 600 is located within the light-transmitting opening 510a of the second sub-color resist layer 512 and the third sub-color resist layer 513 on the side of the first sub-pixel 201a facing away from the substrate 100, and part of the optically transparent adhesive layer 600 is located within the light-transmitting opening 510a of the third sub-color resist layer 513 on the side of the second sub-pixel 201b facing away from the substrate 100".

[0075] In one embodiment of this application, the position of the sidewall of the light-transmitting opening 510a in each sub-color resist layer 510 can be reasonably set to adjust whether the light emitted by the sub-pixel will undergo total internal reflection at the sidewall of the light-transmitting opening 510a, thereby achieving the adjustment of the light emission angle of each sub-pixel.

[0076] Figure 7 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0077] like Figure 7 As shown, by way of example, the functional sub-part 510bb of the first sub-color resist layer 511 has a first side surface 511a facing the light-transmitting opening 510a of the first sub-color resist layer 511, the functional sub-part 510bb of the second sub-color resist layer 512 has a second side surface 512a facing the light-transmitting opening 510a of the second sub-color resist layer 512, and the functional sub-part 510bb of the third sub-color resist layer 513 has a third side surface 513a facing the light-transmitting opening 510a of the third sub-color resist layer 513. By reasonably setting the positions of the first side surface 511a, the second side surface 512a, and the third side surface 513a, it is possible to adjust whether the light emitted by the sub-pixel will undergo total internal reflection at the first side surface 511a, the second side surface 512a, and the third side surface 513a.

[0078] In some examples, the functional surface 221a corresponding to the second sub-pixel 201b has a first virtual connection DL1 between it and the first side surface 511a. When at least one first virtual connection DL1 extends through the light-transmitting opening 510a of the first sub-color resist layer 511 and is spaced apart from the pixel definition layer 230, the light emitted by the second sub-pixel 201b can propagate to the first side surface 511a through the pixel opening 230a with relatively little obstruction, thereby allowing the light emitted by the second sub-pixel 201b to undergo total internal reflection at the first side surface 511a. However, when none of the first virtual connections DL1 are spaced apart from the pixel definition layer 230, that is, when all the first virtual connections DL1 extend through the pixel definition layer 230, the light emitted by the second sub-pixel 201b cannot propagate to the first side surface 511a well due to the obstruction of the pixel definition layer 230, thus the first side surface 511a cannot reflect and gather the light of the second sub-pixel 201b well.

[0079] Similarly, in some examples, there is a second virtual connection DL2 between the functional surface 221a corresponding to the first sub-pixel 201a and the second side surface 512a. When at least one second virtual connection DL2 extends through the light-transmitting opening 510a of the second sub-color resist layer 512 and is spaced apart from the pixel definition layer 230, the light emitted by the first sub-pixel 201a can undergo total internal reflection at the second side surface 512a. However, when none of the second virtual connections DL2 are spaced apart from the pixel definition layer 230, that is, when all the second virtual connections DL2 extend through the pixel definition layer 230, the second side surface 512a cannot reflect and gather the light of the first sub-pixel 201a well due to the occlusion effect of the pixel definition layer 230.

[0080] In some examples, the functional surface 221a corresponding to the third sub-pixel 201c has a third virtual connection DL3 between it and the first side surface 511a. When at least one third virtual connection DL3 extends through the light-transmitting opening 510a of the first sub-color resist layer 511 and is spaced apart from the pixel definition layer 230, the light emitted by the third sub-pixel 201c can undergo total internal reflection at the first side surface 511a. However, when none of the third virtual connections DL3 are spaced apart from the pixel definition layer 230, that is, when all the third virtual connections DL3 extend through the pixel definition layer 230, the first side surface 511a cannot reflect and gather the light of the third sub-pixel 201c well due to the occlusion effect of the pixel definition layer 230.

[0081] In some examples, the functional surface 221a corresponding to the third sub-pixel 201c has a fourth virtual connection DL4 between it and the second side surface 512a. When at least one fourth virtual connection DL4 extends through the light-transmitting opening 510a of the second sub-color resist layer 512 and is spaced apart from the color resist portion 510b of the pixel definition layer 230 and the first sub-color resist layer 511, the light emitted by the third sub-pixel 201c can undergo total internal reflection at the second side surface 512a. However, when none of the fourth virtual connections DL4 can be spaced apart from the color resist portion 510b of the pixel definition layer 230 and the first sub-color resist layer 511, that is, when all the fourth virtual connections DL4 extend through the color resist portion 510b of the pixel definition layer 230 and / or the first sub-color resist layer 511, the second side surface 512a cannot reflect and gather the light of the third sub-pixel 201c well due to the blocking effect of the color resist portion 510b of the pixel definition layer 230 and the first sub-color resist layer 511.

[0082] In some examples, a fifth virtual connection DL5 is provided between the functional surface 221a corresponding to the first sub-pixel 201a and the third side surface 513a. When at least one fifth virtual connection DL5 extends through the light-transmitting opening 510a of the third sub-color resist layer 513 and is spaced apart from the color resist portion 510b of the pixel definition layer 230 and the second sub-color resist layer 512, the light emitted by the first sub-pixel 201a can undergo total internal reflection at the third side surface 513a. However, when none of the fifth virtual connections DL5 can be spaced apart from the color resist portion 510b of the pixel definition layer 230 and the second sub-color resist layer 512, that is, when all the fifth virtual connections DL5 extend through the color resist portion 510b of the pixel definition layer 230 and / or the second sub-color resist layer 512, the third side surface 513a cannot reflect and gather the light of the first sub-pixel 201a well due to the blocking effect of the color resist portion 510b of the pixel definition layer 230 and the second sub-color resist layer 512.

[0083] In some examples, a sixth virtual connection DL6 is provided between the functional surface 221a corresponding to the second sub-pixel 201b and the third side surface 513a. When at least one sixth virtual connection DL6 extends through the light-transmitting opening 510a of the third sub-color resist layer 513 and is spaced apart from the color resist portion 510b of the pixel definition layer 230 and the first sub-color resist layer 511, the light emitted by the second sub-pixel 201b can undergo total internal reflection at the third side surface 513a. However, when none of the sixth virtual connections DL6 can be spaced apart from the color resist portion 510b of the pixel definition layer 230 and the first sub-color resist layer 511, that is, when all the sixth virtual connections DL6 extend through the color resist portion 510b of the pixel definition layer 230 and / or the first sub-color resist layer 511, the third side surface 513a cannot reflect and gather the light of the second sub-pixel 201b well due to the blocking effect of the color resist portion 510b of the pixel definition layer 230 and the first sub-color resist layer 511.

[0084] In some embodiments of this application, the parameters and size of the color resist layer 500 can be adjusted according to the light emission characteristics of different color sub-pixels, so that the light emitted by each sub-pixel has high display uniformity in the filtering and reflection effect of the color resist layer 500, and has low differences in brightness attenuation and viewing angle color deviation, thereby improving the display effect of the display panel 10.

[0085] For example, the parameters and dimensions of the color resist layer 500 can be adjusted according to the size of the light-emitting area of ​​different color sub-pixels. Specifically, the orthographic projection of the pixel opening 230a corresponding to the first sub-pixel 201a onto the substrate 100 has a first area, the orthographic projection of the pixel opening 230a corresponding to the second sub-pixel 201b onto the substrate 100 has a second area, and the orthographic projection of the pixel opening 230a corresponding to the third sub-pixel 201c onto the substrate 100 has a third area. The first, second, and third areas can be different, resulting in differences in the size of the light-emitting areas of the first sub-pixel 201a, the second sub-pixel 201b, and the third sub-pixel 201c. Since sub-pixels with larger light-emitting areas tend to have smaller brightness attenuation and viewing angle color shift, ... Subpixels with smaller light-emitting areas tend to have greater brightness attenuation and viewing angle distortion. Therefore, the parameters and size of the color resist layer 500 above each subpixel can be set according to the size of the light-emitting area of ​​different subpixels. This allows the color resist layer 500 to have a stronger reflection and focusing effect on the light emitted by subpixels with larger light-emitting areas, and a weaker reflection and focusing effect on the light emitted by subpixels with smaller light-emitting areas. This effectively balances the differences in brightness attenuation and viewing angle distortion between subpixels with different light-emitting area sizes, resulting in better display uniformity of the display panel 10 when viewed from different angles.

[0086] In some embodiments, there is a first difference between the refractive index of the first sub-color resist layer 511 and the refractive index of the second sub-color resist layer 512, a second difference between the refractive index of the second sub-color resist layer 512 and the refractive index of the optically transparent adhesive layer 600, a third difference between the refractive index of the third sub-color resist layer 513 and the refractive index of the optically transparent adhesive layer 600, a fourth difference between the refractive index of the third sub-color resist layer 513 and the refractive index of the first sub-color resist layer 511, and a fifth difference between the refractive index of the third sub-color resist layer 513 and the refractive index of the second sub-color resist layer 512, wherein at least two of the first, second, third, fourth, and fifth differences are different.

[0087] By setting at least two of the first, second, third, fourth, and fifth differences to be different, at least two of the following effects are made to differ: the total internal reflection effect at the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512; the total internal reflection effect at the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600; the total internal reflection effect at the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600; the total internal reflection effect at the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511; and the total internal reflection effect at the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512. This is beneficial for achieving different reflective effects of the color resist layer 500 above different sub-pixels based on their light emission characteristics, thereby helping to balance the differences in brightness attenuation and viewing angle bias between sub-pixels of different sizes.

[0088] Optionally, when the refractive index of the third sub-color resist layer 513 is greater than the refractive index of the second sub-color resist layer 512, and the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, the second difference is greater than the third difference, the second difference is greater than the fifth difference, and the second difference is equal to the sum of the third difference and the fifth difference; the fourth difference is greater than the first difference, the fourth difference is greater than the fifth difference, and the fourth difference is equal to the sum of the first difference and the fifth difference.

[0089] In some examples, when the first area is greater than the second area, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the second sub-color resist layer 512, and the second difference is greater than the first difference; and / or, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, and the third difference is greater than the first difference.

[0090] In this example, when the first area is larger than the second area, the first sub-pixel 201a can have a smaller degree of brightness attenuation and viewing angle deviation compared to the second sub-pixel 201b. Therefore, by setting the second difference to be greater than the first difference, the total internal reflection capability of the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a is stronger than the total internal reflection capability of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b. Similarly, by setting the third difference to be greater than the first difference, the total internal reflection capability of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the first sub-pixel 201a is stronger than the total internal reflection capability of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b. Therefore, by setting the second difference to be greater than the first difference and / or the third difference to be greater than the first difference, it is beneficial to improve the reflection and focusing effect of the color resist layer 500 on the light emitted by the first sub-pixel 201a, and to prevent the reflection and focusing effect of the color resist layer 500 on the light emitted by the second sub-pixel 201b from being too strong. This can better balance the difference in brightness attenuation and the difference in viewing angle between the first sub-pixel 201a and the second sub-pixel 201b.

[0091] In some examples, when the first area is greater than the third area, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the second sub-color resist layer 512, and the second difference is greater than the fourth difference; and / or, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, and the third difference is greater than the fourth difference; and / or, the refractive index of the third sub-color resist layer 513 is greater than the refractive index of the second sub-color resist layer 512, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the second sub-color resist layer 512, and the second difference is greater than the fifth difference; and / or, the refractive index of the third sub-color resist layer 513 is greater than the refractive index of the second sub-color resist layer 512, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, and the third difference is greater than the fifth difference.

[0092] In this example, when the first area is larger than the third area, the first sub-pixel 201a can have a smaller degree of brightness attenuation and viewing angle deviation compared to the third sub-pixel 201c. Therefore, by setting the second difference to be greater than the fourth difference, the total internal reflection capability of the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511 above the third sub-pixel 201c. Similarly, by setting the third difference to be greater than the fourth difference, the total internal reflection capability of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the first sub-pixel 201a is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511 above the third sub-pixel 201c. By setting the second difference value to be greater than the fifth difference value, the total internal reflection capability of the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c. Similarly, by setting the third difference value to be greater than the fifth difference value, the total internal reflection capability of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the first sub-pixel 201a.

[0093] Therefore, when the first area is larger than the third area, by reasonably setting the second, third, fourth and fifth differences, it is beneficial to improve the reflection and focusing effect of the color resist layer 500 on the light emitted by the first sub-pixel 201a, and to prevent the reflection and focusing effect of the color resist layer 500 on the light emitted by the third sub-pixel 201c from being too strong. In this way, the difference in brightness attenuation and the difference in viewing angle between the first sub-pixel 201a and the third sub-pixel 201c can be better balanced.

[0094] In some examples, when the second area is larger than the first area, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the second sub-color resist layer 512, and the first difference is greater than the second difference; and / or, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, and the first difference is greater than the third difference.

[0095] In this example, when the second area is larger than the first area, the second sub-pixel 201b can have a smaller degree of brightness attenuation and viewing angle deviation compared to the first sub-pixel 201a. Therefore, by setting the first difference to be greater than the second difference, the total internal reflection capability of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the first sub-pixel 201a is stronger than the total internal reflection capability of the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a. Similarly, by setting the first difference to be greater than the third difference, the total internal reflection capability of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the first sub-pixel 201a. Therefore, by setting the first difference to be greater than the second difference and / or the first difference to be greater than the third difference, it is beneficial to improve the reflection and focusing effect of the color resist layer 500 on the light emitted by the second sub-pixel 201b, and to prevent the reflection and focusing effect of the color resist layer 500 on the light emitted by the first sub-pixel 201a from being too strong, thereby better balancing the difference in brightness attenuation and the difference in viewing angle between the first sub-pixel 201a and the second sub-pixel 201b.

[0096] In some examples, when the second area is larger than the third area, the refractive index of the third sub-color resist layer 513 is greater than the refractive index of the second sub-color resist layer 512, and the first difference is greater than the fifth difference; and / or, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, and the third difference is greater than the fourth difference; and / or, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, the refractive index of the third sub-color resist layer 513 is greater than the refractive index of the second sub-color resist layer 512, and the third difference is greater than the fifth difference.

[0097] In this example, when the second area is larger than the third area, the second sub-pixel 201b can have a smaller degree of brightness attenuation and viewing angle deviation compared to the third sub-pixel 201c. Therefore, by setting the first difference to be greater than the fifth difference, the total internal reflection capability of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the third sub-pixel 201c is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511 above the third sub-pixel 201c. Similarly, by setting the third difference to be greater than the fourth difference, the total internal reflection capability of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511 above the third sub-pixel 201c. By setting the third difference to be greater than the fifth difference, the total internal reflection capability of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c.

[0098] Therefore, when the second area is larger than the third area, by reasonably setting the first difference, the third difference, the fourth difference, and the fifth difference, it is beneficial to improve the reflection and focusing effect of the color resist layer 500 on the light emitted by the second sub-pixel 201b, and to prevent the reflection and focusing effect of the color resist layer 500 on the light emitted by the third sub-pixel 201c from being too strong. In this way, the difference in brightness attenuation and viewing angle bias between the second sub-pixel 201b and the third sub-pixel 201c can be better balanced.

[0099] Optionally, when the second area is greater than the third area, there are several ways to set the relationship between the first difference and the third difference. For example, when the second area is greater than the third area, the first difference can be greater than the third difference; or, the first difference can be equal to the third difference; or, the first difference can be less than the third difference.

[0100] In some examples, when the third area is larger than the first area, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the second sub-color resist layer 512, and the fourth difference is greater than the second difference; and / or, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, and the fourth difference is greater than the third difference; and / or, the refractive index of the third sub-color resist layer 513 is greater than the refractive index of the second sub-color resist layer 512, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, and the fifth difference is greater than the third difference.

[0101] In this example, when the third area is larger than the first area, the third sub-pixel 201c can have a smaller degree of brightness attenuation and viewing angle deviation compared to the first sub-pixel 201a. Therefore, by setting the fourth difference to be greater than the second difference, the total internal reflection capability of the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a is stronger than the total internal reflection capability of the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a. Similarly, by setting the fourth difference to be greater than the third difference, the total internal reflection capability of the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511 above the third sub-pixel 201c is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the first sub-pixel 201a. By setting the fifth difference to be greater than the third difference, the total internal reflection capability of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 located above the third sub-pixel 201c is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the optical transparent adhesive layer 600 above the first sub-pixel 201a.

[0102] Therefore, when the third area is larger than the first area, by reasonably setting the second, third, fourth and fifth differences, it is beneficial to improve the reflection and focusing effect of the color resist layer 500 on the light emitted by the third sub-pixel 201c, and to prevent the reflection and focusing effect of the color resist layer 500 on the light emitted by the first sub-pixel 201a from being too strong. In this way, the difference in brightness attenuation and the difference in viewing angle between the first sub-pixel 201a and the third sub-pixel 201c can be better balanced.

[0103] In some examples, when the third area is greater than the second area, the fourth difference is greater than the first difference; and / or, the refractive index of the third sub-color resist layer 513 is greater than the refractive index of the second sub-color resist layer 512, and the fifth difference is greater than the first difference; and / or, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, and the fourth difference is greater than the third difference; and / or, the refractive index of the optically transparent adhesive layer 600 is greater than the refractive index of the third sub-color resist layer 513, the refractive index of the third sub-color resist layer 513 is greater than the refractive index of the second sub-color resist layer 512, and the fifth difference is greater than the third difference.

[0104] In this example, when the third area is larger than the second area, the third sub-pixel 201c can have a smaller degree of brightness attenuation and viewing angle deviation compared to the second sub-pixel 201b. Therefore, by setting the fourth difference to be greater than the first difference, the total internal reflection capability of the interface between the first sub-color resist layer 511 and the first sub-color resist layer 511 above the second sub-pixel 201b is stronger than the total internal reflection capability of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b. Similarly, by setting the fifth difference to be greater than the first difference, the total internal reflection capability of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c is stronger than the total internal reflection capability of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b. By setting the fourth difference value to be greater than the third difference value, the total internal reflection capability of the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511, located above the third sub-pixel 201c, is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b. By setting the fifth difference value to be greater than the third difference value, the total internal reflection capability of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512, located above the third sub-pixel 201c, is stronger than the total internal reflection capability of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b.

[0105] Therefore, when the third area is larger than the second area, by reasonably setting the first difference, the third difference, the fourth difference, and the fifth difference, it is beneficial to improve the reflection and focusing effect of the color resist layer 500 on the light emitted by the third sub-pixel 201c, and to prevent the reflection and focusing effect of the color resist layer 500 on the light emitted by the second sub-pixel 201b from being too strong. In this way, the difference in brightness attenuation and viewing angle bias between the second sub-pixel 201b and the third sub-pixel 201c can be better balanced.

[0106] Optionally, when the third area is greater than the second area, there are multiple ways to set the relationship between the first difference and the third difference. For example, when the third area is greater than the second area, the first difference can be greater than the third difference; or, the first difference can be equal to the third difference; or, the first difference can be less than the third difference.

[0107] In some embodiments, at least two of the thicknesses of the functional sub-parts 510bb of the first sub-color resist layer 511, the functional sub-parts 510bb of the second sub-color resist layer 512, and the functional sub-parts 510bb of the third sub-color resist layer 513 are different.

[0108] By setting at least two of the thicknesses of the functional sub-parts 510bb of the first sub-color resist layer 511, the second sub-color resist layer 512, and the third sub-color resist layer 513 to be different, at least two of the dimensions of the first side surface 511a of the first sub-color resist layer 511 in the third direction Z, the dimensions of the second side surface 512a of the second sub-color resist layer 512 in the third direction Z, and the dimensions of the third side surface 513a of the third sub-color resist layer 513 in the third direction Z can be different, making the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 reflective. The light intensity, the amount of light reflected at the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600, the amount of light reflected at the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600, the amount of light reflected at the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511, and the amount of light reflected at the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 are different. This is beneficial for the color resist layer 500 above different sub-pixels to have different reflective effects according to the light emission characteristics of different color sub-pixels, thereby helping to balance the differences in brightness attenuation and viewing angle color deviation between sub-pixels of different sizes.

[0109] Figure 8 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0110] Please see Figure 8 In some examples, when the first area is larger than the second area, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512 is greater than the thickness of the functional sub-part 510bb of the first sub-color resist layer 511; and / or, the thickness of the color resist portion 510b of the third sub-color resist layer 513 is greater than the thickness of the functional sub-part 510bb of the first sub-color resist layer 511; and / or, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512 is greater than the thickness of the functional sub-part 510bb of the third sub-color resist layer 513.

[0111] In this example, when the first area is larger than the second area, the first sub-pixel 201a can have a smaller degree of brightness attenuation and viewing angle deviation compared to the second sub-pixel 201b. Therefore, by setting the thickness of the functional sub-part 510bb of the second sub-color resist layer 512 to be greater than the thickness of the functional sub-part 510bb of the first sub-color resist layer 511, the size of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b in the third direction Z is larger than the size of the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a in the third direction Z. This makes it easier for more light emitted from the first sub-pixel 201a to be reflected at the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a. Similarly, by setting the thickness of the color resist portion 510b of the third sub-color resist layer 513 to be greater than the thickness of the functional portion 510bb of the first sub-color resist layer 511, the size of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the first sub-pixel 201a in the third direction Z. This makes it easier for more light emitted from the first sub-pixel 201a to be reflected at the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the first sub-pixel 201a. By setting the thickness of the functional sub-section 510bb of the second sub-color resist layer 512 to be greater than the thickness of the functional sub-section 510bb of the third sub-color resist layer 513, the size of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b in the third direction Z is larger than the size of the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a in the third direction Z. This makes it easier for more light emitted from the first sub-pixel 201a to be reflected at the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a.

[0112] Therefore, when the first area is larger than the second area, by reasonably setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512, and the thickness of the functional sub-part 510bb of the third sub-color resist layer 513, it is beneficial to improve the reflection and focusing effect of the color resist layer on the light emitted by the first sub-pixel 201a, and to prevent the reflection and focusing effect of the color resist layer 500 on the light emitted by the second sub-pixel 201b from being too strong. In this way, the brightness attenuation difference and viewing angle difference between the first sub-pixel 201a and the second sub-pixel 201b can be better balanced.

[0113] Figure 9This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0114] Please see Figure 9 In some examples, when the first area is larger than the third area, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512 is greater than the thickness of the functional sub-part 510bb of the first sub-color resist layer 511; and / or, the thickness of the functional sub-part 510bb of the third sub-color resist layer 513 is greater than the thickness of the functional sub-part 510bb of the first sub-color resist layer 511; and / or, the thickness of the functional sub-part 510bb of the third sub-color resist layer 513 is greater than the thickness of the functional sub-part 510bb of the second sub-color resist layer 512.

[0115] In this example, when the first area is larger than the third area, the first sub-pixel 201a can have a smaller degree of brightness attenuation and viewing angle deviation compared to the third sub-pixel 201c. Therefore, by setting the thickness of the functional sub-part 510bb of the second sub-color resist layer 512 to be greater than the thickness of the functional sub-part 510bb of the first sub-color resist layer 511, the size of the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511 above the third sub-pixel 201c in the third direction Z is larger than the size of the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a in the third direction Z. This makes it easier for more light emitted from the first sub-pixel 201a to be reflected at the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a. Similarly, by setting the thickness of the functional sub-part 510bb of the third sub-color resist layer 513 to be greater than the thickness of the functional sub-part 510bb of the first sub-color resist layer 511, the size of the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511 above the third sub-pixel 201c in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the first sub-pixel 201a in the third direction Z. This makes it easier for more light emitted from the first sub-pixel 201a to be reflected at the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the first sub-pixel 201a. By setting the thickness of the functional sub-section 510bb of the third sub-color resist layer 513 to be greater than the thickness of the functional sub-section 510bb of the second sub-color resist layer 512, the size of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the first sub-pixel 201a in the third direction Z. This makes it easier for more light emitted from the first sub-pixel 201a to be reflected at the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the first sub-pixel 201a.

[0116] Therefore, when the first area is larger than the third area, by reasonably setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512, and the thickness of the functional sub-part 510bb of the third sub-color resist layer 513, it is beneficial to improve the reflection and focusing effect of the color resist layer on the light emitted by the first sub-pixel 201a, and to prevent the reflection and focusing effect of the color resist layer 500 on the light emitted by the third sub-pixel 201c from being too strong. In this way, the brightness attenuation difference and viewing angle difference between the first sub-pixel 201a and the third sub-pixel 201c can be better balanced.

[0117] Figure 10 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0118] Please see Figure 10 In some examples, when the second area is larger than the first area, the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 is greater than the thickness of the functional sub-part 510bb of the second sub-color resist layer 512; and / or, the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 is greater than the thickness of the functional sub-part 510bb of the third sub-color resist layer 513; and / or, the thickness of the functional sub-part 510bb of the third sub-color resist layer 513 is greater than the thickness of the functional sub-part 510bb of the second sub-color resist layer 512.

[0119] In this example, when the second area is larger than the first area, the second sub-pixel 201b can have a smaller degree of brightness attenuation and viewing angle deviation compared to the first sub-pixel 201a. Therefore, by setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 to be greater than the thickness of the functional sub-part 510bb of the second sub-color resist layer 512, the size of the interface between the second sub-color resist layer 512 above the first sub-pixel 201a and the optically transparent adhesive layer 600 in the third direction Z is larger than the size of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b in the third direction Z. This makes it easier for more light emitted from the second sub-pixel 201b to be reflected at the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b. Similarly, by setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 to be greater than the thickness of the functional sub-part 510bb of the third sub-color resist layer 513, the size of the interface between the third sub-color resist layer 513 and the optical transparent adhesive layer 600 above the first sub-pixel 201a in the third direction Z is larger than the size of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b in the third direction Z. This makes it easier for more light emitted from the second sub-pixel 201b to be reflected at the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b. By setting the thickness of the functional sub-section 510bb of the third sub-color resist layer 513 to be greater than the thickness of the functional sub-section 510bb of the second sub-color resist layer 512, the size of the interface between the second sub-color resist layer 512 and the optically transparent adhesive layer 600 above the first sub-pixel 201a in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b in the third direction Z. This makes it easier for more light emitted from the second sub-pixel 201b to be reflected at the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b.

[0120] Therefore, when the second area is larger than the first area, by reasonably setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512, and the thickness of the functional sub-part 510bb of the third sub-color resist layer 513, it is beneficial to improve the reflection and focusing effect of the color resist layer on the light emitted by the second sub-pixel 201b, and to prevent the reflection and focusing effect of the color resist layer 500 on the light emitted by the first sub-pixel 201a from being too strong. In this way, the brightness attenuation difference and viewing angle difference between the first sub-pixel 201a and the second sub-pixel 201b can be better balanced.

[0121] Figure 11This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0122] Please see Figure 11 In some examples, when the second area is larger than the third area, the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 is greater than the thickness of the functional sub-part 510bb of the second sub-color resist layer 512; and / or, the thickness of the functional sub-part 510bb of the third sub-color resist layer 513 is greater than the thickness of the functional sub-part 510bb of the first sub-color resist layer 511; and / or, the thickness of the functional sub-part 510bb of the third sub-color resist layer 513 is greater than the thickness of the functional sub-part 510bb of the second sub-color resist layer 512.

[0123] In this example, when the second area is larger than the third area, the second sub-pixel 201b can have a smaller degree of brightness attenuation and viewing angle deviation compared to the third sub-pixel 201c. Therefore, by setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 to be greater than the thickness of the functional sub-part 510bb of the second sub-color resist layer 512, the size of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c in the third direction Z is larger than the size of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b in the third direction Z. This makes it easier for more light emitted from the second sub-pixel 201b to be reflected at the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b. Similarly, by setting the thickness of the functional sub-part 510bb of the third sub-color resist layer 513 to be greater than the thickness of the functional sub-part 510bb of the first sub-color resist layer 511, the size of the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511 above the third sub-pixel 201c in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b in the third direction Z. This makes it easier for more light emitted from the second sub-pixel 201b to be reflected at the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b. By setting the thickness of the functional sub-section 510bb of the third sub-color resist layer 513 to be greater than the thickness of the functional sub-section 510bb of the second sub-color resist layer 512, the size of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b in the third direction Z. This makes it easier for more light emitted from the second sub-pixel 201b to be reflected at the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b.

[0124] Therefore, when the second area is larger than the third area, by reasonably setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512, and the thickness of the functional sub-part 510bb of the third sub-color resist layer 513, it is beneficial to improve the reflection and focusing effect of the color resist layer on the light emitted by the second sub-pixel 201b, and to prevent the reflection and focusing effect of the color resist layer 500 on the light emitted by the third sub-pixel 201c from being too strong. In this way, the brightness attenuation difference and viewing angle difference between the second sub-pixel 201b and the third sub-pixel 201c can be better balanced.

[0125] Figure 12 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application. Please see Figure 12 In some examples, when the third area is larger than the first area, the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 is greater than the thickness of the functional sub-part 510bb of the second sub-color resist layer 512; and / or, the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 is greater than the thickness of the functional sub-part 510bb of the third sub-color resist layer 513; and / or, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512 is greater than the thickness of the functional sub-part 510bb of the third sub-color resist layer 513.

[0126] In this example, when the third area is larger than the first area, the third sub-pixel 201c can have a smaller degree of brightness attenuation and viewing angle deviation compared to the first sub-pixel 201a. Therefore, by setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 to be greater than the thickness of the functional sub-part 510bb of the second sub-color resist layer 512, the size of the interface between the second sub-color resist layer 512 above the first sub-pixel 201a and the optically transparent adhesive layer 600 in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 above the third sub-pixel 201c and the first sub-color resist layer 511 in the third direction Z. This makes it easier for more light emitted from the third sub-pixel 201c to be reflected at the interface between the third sub-color resist layer 513 above the third sub-pixel 201c and the first sub-color resist layer 511. Similarly, by setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 to be greater than the thickness of the functional sub-part 510bb of the third sub-color resist layer 513, the size of the interface between the third sub-color resist layer 513 and the optical transparent adhesive layer 600 above the first sub-pixel 201a in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511 above the third sub-pixel 201c in the third direction Z. This makes it easier for more light emitted from the third sub-pixel 201c to be reflected at the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511 above the third sub-pixel 201c. By setting the thickness of the functional sub-section 510bb of the second sub-color resist layer 512 to be greater than the thickness of the functional sub-section 510bb of the third sub-color resist layer 513, the size of the interface between the third sub-color resist layer 513 and the optical transparent adhesive layer 600 above the first sub-pixel 201a in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c in the third direction Z. This makes it easier for more light emitted from the third sub-pixel 201c to be reflected at the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c.

[0127] Therefore, when the third area is larger than the first area, by reasonably setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512, and the thickness of the functional sub-part 510bb of the third sub-color resist layer 513, it is beneficial to improve the reflection and focusing effect of the color resist layer on the light emitted by the third sub-pixel 201c, and to prevent the reflection and focusing effect of the color resist layer 500 on the light emitted by the first sub-pixel 201a from being too strong. In this way, the brightness attenuation difference and viewing angle difference between the first sub-pixel 201a and the third sub-pixel 201c can be better balanced.

[0128] Figure 13This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0129] Please see Figure 13 In some examples, when the third area is larger than the second area, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512 is greater than the thickness of the functional sub-part 510bb of the first sub-color resist layer 511; and / or, the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 is greater than the thickness of the functional sub-part 510bb of the third sub-color resist layer 513; and / or, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512 is greater than the thickness of the functional sub-part 510bb of the third sub-color resist layer 513.

[0130] In this example, when the third area is larger than the second area, the third sub-pixel 201c can have a smaller degree of brightness attenuation and viewing angle deviation compared to the second sub-pixel 201b. Therefore, by setting the thickness of the functional sub-part 510bb of the second sub-color resist layer 512 to be greater than the thickness of the functional sub-part 510bb of the first sub-color resist layer 511, the size of the interface between the first sub-color resist layer 511 and the second sub-color resist layer 512 above the second sub-pixel 201b in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c in the third direction Z. This makes it easier for more light emitted from the third sub-pixel 201c to be reflected at the interface between the third sub-color resist layer 513 and the first sub-color resist layer 511 above the third sub-pixel 201c. Similarly, by setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511 to be greater than the thickness of the functional sub-part 510bb of the third sub-color resist layer 513, the size of the interface between the third sub-color resist layer 513 above the second sub-pixel 201b and the optically transparent adhesive layer 600 in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 above the third sub-pixel 201c and the first sub-color resist layer 511 in the third direction Z. This makes it easier for more light emitted from the third sub-pixel 201c to be reflected at the interface between the third sub-color resist layer 513 above the third sub-pixel 201c and the first sub-color resist layer 511. By setting the thickness of the functional sub-section 510bb of the second sub-color resist layer 512 to be greater than the thickness of the functional sub-section 510bb of the third sub-color resist layer 513, the size of the interface between the third sub-color resist layer 513 and the optically transparent adhesive layer 600 above the second sub-pixel 201b in the third direction Z is larger than the size of the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c in the third direction Z. This makes it easier for more light emitted from the third sub-pixel 201c to be reflected at the interface between the third sub-color resist layer 513 and the second sub-color resist layer 512 above the third sub-pixel 201c.

[0131] Therefore, when the third area is larger than the second area, by reasonably setting the thickness of the functional sub-part 510bb of the first sub-color resist layer 511, the thickness of the functional sub-part 510bb of the second sub-color resist layer 512, and the thickness of the functional sub-part 510bb of the third sub-color resist layer 513, it is beneficial to improve the reflection and focusing effect of the color resist layer 500 on the light emitted by the third sub-pixel 201c, and to prevent the reflection and focusing effect of the color resist layer on the light emitted by the second sub-pixel 201b from being too strong. In this way, the brightness attenuation difference and viewing angle difference between the second sub-pixel 201b and the third sub-pixel 201c can be better balanced.

Figure 15 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application. Figure 16 This is a partial cross-sectional view of a display panel 10 provided in another embodiment of this application.

[0133] Please see Figures 14 to 16 Optionally, the pixel opening 230a corresponding to the first sub-pixel 201a has a first orthographic projection on the substrate, the light-transmitting opening 510a of the second sub-color resist layer 512 corresponding to the first sub-pixel 201a has a second orthographic projection on the substrate, the light-transmitting opening 510a of the third sub-color resist layer 513 corresponding to the first sub-pixel 201a has a third orthographic projection on the substrate, and there is a first spacing S1 between the edge of the first orthographic projection and the edge of the second orthographic projection, and / or there is a first spacing S1 between the edge of the second orthographic projection and the edge of the third orthographic projection.

[0135] The pixel opening 230a corresponding to the third sub-pixel 201c has a seventh orthographic projection on the substrate, the light-transmitting opening 510a of the first sub-color resist layer 511 corresponding to the third sub-pixel 201c has an eighth orthographic projection on the substrate, the light-transmitting opening 510a of the second sub-color resist layer 512 corresponding to the third sub-pixel 201c has a ninth orthographic projection on the substrate, and there is a third spacing S3 between the edge of the seventh orthographic projection and the edge of the eighth orthographic projection, and / or there is a third spacing S3 between the edge of the eighth orthographic projection and the edge of the ninth orthographic projection.

[0136] Optionally, the first orthographic projection can be the orthographic projection of the inner wall surface of the pixel opening 230a corresponding to the first sub-pixel 201a onto the substrate 100 and the projection area formed therein; the second orthographic projection can be the orthographic projection of the inner wall surface of the light-transmitting opening 510a of the second sub-color resist layer 512 corresponding to the first sub-pixel 201a onto the substrate 100 and the projection area formed therein; the third orthographic projection can be the orthographic projection of the inner wall surface of the light-transmitting opening 510a of the third sub-color resist layer 513 corresponding to the first sub-pixel 201a onto the substrate 100 and the projection area formed therein; the fourth orthographic projection can be the orthographic projection of the inner wall surface of the pixel opening 230a corresponding to the second sub-pixel 201b onto the substrate 100 and the projection area formed therein; and the fifth orthographic projection can be the light-transmitting opening 510a of the first sub-color resist layer 511 corresponding to the second sub-pixel 201b. The first orthographic projection of the inner wall surface of 0a onto the substrate 100 and the projection area it encloses; the sixth orthographic projection can be the orthographic projection of the inner wall surface of the light-transmitting opening 510a of the third sub-color resist layer 513 corresponding to the second sub-pixel 201b onto the substrate 100 and the projection area it encloses; the seventh orthographic projection can be the orthographic projection of the inner wall surface of the pixel opening 230a corresponding to the third sub-pixel 201c onto the substrate 100 and the projection area it encloses; the eighth orthographic projection can be the orthographic projection of the inner wall surface of the light-transmitting opening 510a of the first sub-color resist layer 511 corresponding to the third sub-pixel 201c onto the substrate 100 and the projection area it encloses; the ninth orthographic projection can be the orthographic projection of the inner wall surface of the light-transmitting opening 510a of the second sub-color resist layer 512 corresponding to the third sub-pixel 201c onto the substrate 100 and the projection area it encloses.

[0137] Optionally, the distance between the edge of the first orthographic projection and the edge of the second orthographic projection, and the distance between the edge of the second orthographic projection and the edge of the third orthographic projection, may be equal or unequal; the distance between the edge of the fourth orthographic projection and the edge of the fifth orthographic projection, and the distance between the edge of the fifth orthographic projection and the edge of the sixth orthographic projection, may be equal or unequal; the distance between the edge of the seventh orthographic projection and the edge of the eighth orthographic projection, and the distance between the edge of the eighth orthographic projection and the edge of the ninth orthographic projection, may be equal or unequal.

[0138] In some embodiments, at least two of the first spacing S1, the second spacing S2, and the third spacing S3 are different, such that at least two of the reflection effects of light emitted from the first sub-pixel 201a, the second sub-pixel 201b, and the third sub-pixel 201c on the color resist layer 500 are different. This is beneficial for the color resist layer 500 above different sub-pixels to have different reflective effects based on the light emission characteristics of different color sub-pixels, thereby helping to balance the differences in brightness attenuation and viewing angle bias between sub-pixels of different sizes.

[0139] Optionally, the area of ​​the first orthographic projection is the first area, the area of ​​the fourth orthographic projection is the second area, and the area of ​​the seventh orthographic projection is the third area.

[0140] Please see Figure 14 In some examples, when the first area is greater than the second area, the first spacing S1 is less than the second spacing S2.

[0141] Optionally, the first spacing S1 being less than the second spacing S2 can refer to the spacing between the edges of the first orthographic projection and the second orthographic projection, which is less than the spacing between the edges of the fourth orthographic projection and the fifth orthographic projection; and / or, the first spacing S1 being less than the second spacing S2 can refer to the spacing between the edges of the first orthographic projection and the second orthographic projection, which is less than the spacing between the edges of the fifth orthographic projection and the sixth orthographic projection; and / or, the first spacing S1 being less than the second spacing S2 can refer to the spacing between the edges of the second orthographic projection and the third orthographic projection, which is less than the spacing between the edges of the fourth orthographic projection and the fifth orthographic projection; and / or, the first spacing S1 being less than the second spacing S2 can refer to the spacing between the edges of the second orthographic projection and the third orthographic projection, which is less than the spacing between the edges of the fifth orthographic projection and the sixth orthographic projection.

[0142] In this example, when the first area is larger than the second area, the first sub-pixel 201a can have a smaller degree of brightness attenuation and viewing angle deviation compared to the second sub-pixel 201b. Therefore, by setting the first spacing S1 to be smaller than the second spacing S2, the light-transmitting openings 510a of the second sub-color resist layer 512 and the third sub-color resist layer 513 above the first sub-pixel 201a can have smaller sizes, and the light-transmitting openings 510a of the first sub-color resist layer 511 and the third sub-color resist layer 513 above the second sub-pixel 201b can have larger sizes. This is beneficial for improving the reflection and focusing effect of the color resist layer 500 on the light emitted from the first sub-pixel 201a, and also prevents the reflection and focusing effect of the color resist layer on the light emitted from the second sub-pixel 201b from being too strong. Thus, it can better balance the difference in brightness attenuation and viewing angle deviation between the first sub-pixel 201a and the second sub-pixel 201b.

[0143] Please continue reading. Figure 14 In some examples, when the first area is greater than the third area, the first spacing S1 is less than the third spacing S3.

[0144] Optionally, the first spacing S1 being less than the third spacing S3 can refer to the spacing between the edge of the first orthographic projection and the edge of the second orthographic projection, which is less than the spacing between the edge of the seventh orthographic projection and the edge of the eighth orthographic projection; and / or, the first spacing S1 being less than the second spacing S2 can refer to the spacing between the edge of the first orthographic projection and the edge of the second orthographic projection, which is less than the spacing between the edge of the eighth orthographic projection and the edge of the ninth orthographic projection; and / or, the first spacing S1 being less than the third spacing S3 can refer to the spacing between the edge of the second orthographic projection and the edge of the third orthographic projection, which is less than the spacing between the edge of the seventh orthographic projection and the edge of the eighth orthographic projection; and / or, the first spacing S1 being less than the third spacing S3 can refer to the spacing between the edge of the second orthographic projection and the edge of the third orthographic projection, which is less than the spacing between the edge of the eighth orthographic projection and the edge of the ninth orthographic projection.

[0145] In this example, when the first area is larger than the third area, the first sub-pixel 201a can have a smaller degree of brightness attenuation and viewing angle deviation compared to the third sub-pixel 201c. Therefore, by setting the first spacing S1 to be smaller than the third spacing S3, the light-transmitting openings 510a of the second sub-color resist layer 512 and the third sub-color resist layer 513 above the first sub-pixel 201a can have smaller sizes, and the light-transmitting openings 510a of the first sub-color resist layer 511 and the second sub-color resist layer 512 above the third sub-pixel 201c can have larger sizes. This is beneficial to improving the reflection and focusing effect of the color resist layer 500 on the light emitted by the first sub-pixel 201a, and to prevent the reflection and focusing effect of the color resist layer on the light emitted by the third sub-pixel 201c from being too strong. Thus, it is possible to better balance the difference in brightness attenuation and viewing angle deviation between the first sub-pixel 201a and the third sub-pixel 201c.

[0146] Please see Figure 15 In some examples, when the second area is greater than the first area, the second spacing S2 is less than the first spacing S1.

[0147] Optionally, the second spacing S2 being less than the first spacing S1 can refer to the spacing between the edge of the fourth orthographic projection and the edge of the fifth orthographic projection, which is less than the spacing between the edge of the first orthographic projection and the edge of the second orthographic projection; and / or, the second spacing S2 being less than the first spacing S1 can refer to the spacing between the edge of the fifth orthographic projection and the edge of the sixth orthographic projection, which is less than the spacing between the edge of the first orthographic projection and the edge of the second orthographic projection; and / or, the second spacing S2 being less than the first spacing S1 can refer to the spacing between the edge of the fourth orthographic projection and the edge of the fifth orthographic projection, which is less than the spacing between the edge of the second orthographic projection and the edge of the third orthographic projection; and / or, the second spacing S2 being less than the first spacing S1 can refer to the spacing between the edge of the fifth orthographic projection and the edge of the sixth orthographic projection, which is less than the spacing between the edge of the second orthographic projection and the edge of the third orthographic projection.

[0148] In this example, when the second area is larger than the first area, the second sub-pixel 201b can have a smaller degree of brightness attenuation and viewing angle deviation compared to the first sub-pixel 201a. Therefore, by setting the second spacing S2 to be smaller than the first spacing S1, the light-transmitting openings 510a of the first sub-color resist layer 511 and the third sub-color resist layer 513 above the second sub-pixel 201b can have smaller sizes, and the light-transmitting openings 510a of the second sub-color resist layer 512 and the third sub-color resist layer 513 above the first sub-pixel 201a can have larger sizes. This is beneficial to improving the reflection and focusing effect of the color resist layer 500 on the light emitted by the second sub-pixel 201b, and also prevents the reflection and focusing effect of the color resist layer on the light emitted by the first sub-pixel 201a from being too strong. Thus, it can better balance the difference in brightness attenuation and viewing angle deviation between the first sub-pixel 201a and the second sub-pixel 201b.

[0149] Please continue reading. Figure 15 In some examples, when the second area is greater than the third area, the second spacing S2 is less than the third spacing S3.

[0151] In this example, when the second area is larger than the third area, the second sub-pixel 201b can have a smaller degree of brightness attenuation and viewing angle deviation compared to the third sub-pixel 201c. Therefore, by setting the second spacing S2 to be smaller than the third spacing S3, the light-transmitting openings 510a of the first sub-color resist layer 511 and the third sub-color resist layer 513 above the second sub-pixel 201b can have smaller sizes, and the light-transmitting openings 510a of the first sub-color resist layer 511 and the second sub-color resist layer 512 above the third sub-pixel 201c can have larger sizes. This is beneficial for improving the reflection and focusing effect of the color resist layer 500 on the light emitted by the second sub-pixel 201b, and also prevents the reflection and focusing effect of the color resist layer on the light emitted by the third sub-pixel 201c from being too strong. Thus, it can better balance the difference in brightness attenuation and viewing angle deviation between the second sub-pixel 201b and the third sub-pixel 201c.

[0152] Please see Figure 16 In some examples, when the third area is greater than the first area, the third spacing S3 is less than the first spacing S1.

[0154] In this example, when the third area is larger than the first area, the third sub-pixel 201c can have a smaller degree of brightness attenuation and viewing angle deviation compared to the first sub-pixel 201a. Therefore, by setting the third spacing S3 to be smaller than the first spacing S1, the light-transmitting openings 510a of the first sub-color resist layer 511 and the second sub-color resist layer 512 above the third sub-pixel 201c can have smaller sizes, and the light-transmitting openings 510a of the second sub-color resist layer 512 and the third sub-color resist layer 513 above the first sub-pixel 201a can have larger sizes.

Thus, it can better balance the difference in brightness attenuation and viewing angle deviation between the first sub-pixel 201a and the third sub-pixel 201c.

[0155] Please continue reading. Figure 16 In some examples, when the third area is greater than the second area, the third spacing S3 is less than the second spacing S2.
