[0002] Due to its advantages such as light weight, high brightness, low power consumption, fast response, high clarity, good flexibility and high luminous efficiency, OLED (Organic Light-Emitting Diode) display panels are widely used in display devices such as mobile phones, computers, and wearable devices.

[0003] In order to reduce the reflectivity of ambient light irradiated to the OLED display panel, a polarizer is often added to the OLED display panel, and the polarizer may cause the display brightness of the OLED display panel to be greatly reduced (by about 58%).

[0046] In the related art, a COE (Color Filter On Encapsulation Layer) structure is used to replace the polarizer, thereby improving the display brightness of the OLED display panel. The COE structure includes a color filter layer arranged on the encapsulation layer of the display panel, and the color filter layer includes a plurality of color blocks, such as a plurality of red color blocks, a plurality of blue color blocks, and a plurality of green color blocks. After the ambient light enters the OLED display panel, it is reflected by structures such as pixel units in the display panel to generate reflected light, and the reflected light passes through the encapsulation layer and then exits through a plurality of light-transmitting color blocks. Due to the large thickness of the encapsulation layer, diffraction occurs when the reflected light passes through a plurality of color blocks during transmission. Since the plurality of color blocks have different sizes and colors, the reflected light emitted through the plurality of color blocks also has different colors. The light intensity of the diffracted light of the reflected light at the color blocks of different colors may be different, so that the diffracted reflected light presents different colors on the surface of the OLED display panel, making it difficult to control the color presented on the surface of the OLED display panel.

[0047] For example, Figure 1 and Figure 2 As shown, Figure 1 and Figure 2The graph shows the change in diffracted light intensity after the reflected light is diffracted by the blue, green and red color blocks. The X-axis represents the radius corresponding to the diffraction position of the reflected light with the center of the display panel as the origin, the Y-axis represents the relative intensity of the diffracted light, the dashed line represents the intensity change curve of the blue light generated after the reflected light is diffracted by the blue color block, the dotted line represents the intensity change curve of the green light generated after the reflected light is diffracted by the green color block, and the solid line represents the intensity change curve of the red light generated after the reflected light is diffracted by the red color block. Figure 1 and Figure 2 It can be seen that the intensity of blue light decays the fastest, and the intensity of red light decays the slowest. And at a specific position of the display panel, the intensity of light of each color is different. For example, at a radius of 0.6 cm with the center of the display panel as the origin, the intensity of blue light is less than that of red light, and the intensity of blue light is greater than that of green light, which makes the light at this position merge to produce purple light. The light intensities of different colors of light at different positions are different, resulting in different colors of light at different positions of the display panel, making the color presented on the surface of the display panel difficult to control.

[0048] In order to achieve the control and adjustment of the color of the display panel surface after the ambient light irradiates the display panel, the embodiment of the present application provides a display panel, a method for manufacturing a display panel and a display device. The display panel, the method for manufacturing a display panel and the display device provided in the embodiment of the present application will be described in detail with reference to the accompanying drawings. Among them, the display panel can be an LCD (Liquid Crystal Display), an electroluminescent display panel or a photoluminescent display panel. In the case where the display panel is an electroluminescent display panel, the electroluminescent display panel can be an OLED (Organic Light-Emitting Diode) or a QLED (Quantum Dot Light Emitting Diodes). In the case where the display panel is a photoluminescent display panel, the photoluminescent display panel can be a quantum dot photoluminescent display panel.

[0049] The embodiment of the first aspect of the present application provides a display panel 100, such as Figure 3 , Figure 4 and Figure 5As shown, the display panel 100 includes a base substrate 1 and a plurality of pixel units 10 located on one side of the base substrate 1, wherein the pixel unit 10 includes a plurality of pixels; the display panel 100 also includes an encapsulation layer 5, a color filter substrate 6 and a plurality of shading blocks 7, wherein the encapsulation layer 5 is located on a side of the plurality of pixel units 10 away from the base substrate 1 and covers the plurality of pixel units 10; the color filter substrate 6 is located on a side of the encapsulation layer 5 away from the base substrate 1, the color filter substrate 6 includes a black matrix layer 61 and a color filter layer 62, the black matrix layer 61 includes a plurality of first hollow areas 610 arranged at intervals, the color filter layer 62 includes a plurality of color resist blocks 620, the plurality of color resist blocks 620 fill the plurality of first hollow areas 610 and are arranged corresponding to the plurality of pixels included in the plurality of pixel units 10, the color resist block 620 corresponding to at least one pixel included in the pixel unit 10 includes a plurality of second hollow areas 6211 arranged at intervals; and the plurality of shading blocks 7 fill the plurality of second hollow areas 6211.

[0050] In the present application embodiment, Figure 4 As shown, the encapsulation layer 5 is disposed above the plurality of pixel units 10 and covers the plurality of pixel units 10 to encapsulate the structures such as the pixel units 10 below, thereby reducing the probability of failure of the plurality of pixel units 10 due to the entry of impurities such as water and oxygen into the pixel units 10. Optionally, the encapsulation layer 5 may be a thin film encapsulation layer, and the material of the encapsulation layer 5 includes silicon oxide, silicon oxynitride, and silicon nitride. Optionally, the encapsulation layer 5 may be a multi-layer structure. When the encapsulation layer 5 is a multi-layer structure, the encapsulation layer 5 may include two inorganic encapsulation layers and an organic encapsulation layer or a metal layer located within the two inorganic encapsulation layers to further enhance the encapsulation effect of the encapsulation layer 5.

[0051] In the present application embodiment, Figure 4As shown, the color filter substrate 6 is located above the encapsulation layer 5, and the color filter substrate 6 includes a black matrix layer 61 and a color filter layer 62. The black matrix layer 61 includes a plurality of first hollow areas 610 arranged at intervals, and the plurality of first hollow areas 610 are used to accommodate a plurality of color resist blocks 620. The other areas of the black matrix layer 61 except the plurality of first hollow areas 610 can be coated with an opaque black light-shielding dye. The black matrix layer 61 is used to reduce the probability of optical crosstalk between adjacent pixel units 10, reduce the reflectivity of the display panel 100, and improve the display effect of the display panel 100. The color filter layer 62 includes a plurality of color resist blocks 620, which fill the plurality of first hollow areas 610 and are arranged corresponding to the plurality of pixels, that is, along the direction perpendicular to the base substrate 1, the orthographic projection of each color resist block 620 on the base substrate 1 covers the orthographic projection of the corresponding pixel on the base substrate 1. The color resist blocks 620 are arranged corresponding to the pixels so that the light emitted by the light-emitting unit 3 included in the pixel can pass more through the color resist blocks 620, thereby improving the transmittance of the display panel 100 and further improving the display effect. The color of the color resist block 620 is also arranged corresponding to the color of the light-emitting unit 3, and the color resist block 620 may include a blue color resist block, a green color resist block or a red color resist block, which is not limited in the present application.

[0052] In the embodiment of the present application, a plurality of shading blocks 7 are light-proof structures. The shading blocks 7 can be made of light-proof materials, or light-proof dyes can be coated on the surface of the shading blocks 7 to make them light-proof, so as to achieve a light-shielding effect. The materials and manufacturing methods of the shading blocks 7 can be set according to actual needs, and the present application does not limit this. Optionally, the substrate substrate 1 can be a rigid substrate substrate, such as a glass substrate substrate. The substrate substrate 1 can also be a flexible substrate substrate, such as a polyimide substrate substrate, and the present application does not limit this.

[0053] In the present application embodiment, Figure 4 As shown, when the reflected light generated by the ambient light reflected by the internal structure of the display panel 100 reaches the multiple color-resistance blocks 620, the reflected light is diffracted at the multiple color-resistance blocks 620 due to the shielding of the black matrix layer 61. Filling multiple light-shielding blocks 7 in the color-resistance block 620 corresponding to at least one pixel can adjust the size of the light-transmitting area in the color-resistance block 620, thereby adjusting the diffraction range of the reflected light at the color-resistance block 620 provided with the light-shielding blocks 7, and further adjusting the intensity of the diffracted light of the reflected light at the color-resistance block 620 provided with the light-shielding blocks 7, and can adjust the difference in the intensity of the diffracted light of the reflected light at the color-resistance blocks 620 of different colors and sizes, so as to adjust the intensity of the diffracted light after the reflected light is diffracted by different color-resistance blocks 620, so that the surface of the display panel 100 presents the desired color, such as white, yellow or color, etc., and realizes the control and adjustment of the color of the surface of the display panel 100 after the ambient light is irradiated to the display panel 100.

[0054] In some embodiments, the pixel unit 10 includes a first pixel and a second pixel, and the color filter layer 62 includes a first color block 621 corresponding to the first pixel, and a second color block 622 corresponding to the second pixel. Along the long side direction Y and / or the wide side direction X of the base substrate 1, the size of the first color block 621 is larger than the size of the second color block 622, and the first color block 621 includes a plurality of second hollow areas 6211 arranged at intervals.

[0055] In the embodiment of the present application, when the shapes of the first color block 621 and the second color block 622 are substantially rectangular, along the long side direction Y of the base substrate 1, the size of the first color block 621 is the length of the first color block 621, and the size of the second color block 622 is the length of the second color block 622. Along the wide side direction X of the base substrate 1, the size of the first color block 621 is the width of the first color block 621, and the size of the second color block 622 is the width of the second color block 622.

[0056] In the embodiment of the present application, a plurality of second hollow areas 6211 arranged at intervals are provided in the first color block 621, and the second hollow area 6211 is filled with a light shielding block 7. Filling a plurality of light shielding blocks 7 in the first color block 621 with a larger size can adjust the size of the light-transmitting area in the first color block 621, thereby adjusting the diffraction range of the reflected light at the first color block 621, and then adjusting the intensity of the diffracted light of the reflected light at the first color block 621, and can reduce the difference in the intensity of the diffracted light of the reflected light at the first color block 621 and the second color block 622, so that the intensity of the diffracted light after the reflected light is diffracted by different color blocks 620 is similar, so that the diffracted light after diffracting by different color blocks 620 can be more fused into white light, thereby increasing the color consistency of the surface of the display panel 100, realizing the control and adjustment of the color of the surface of the display panel 100 after the ambient light is irradiated to the display panel 100, improving the phenomenon of color separation of the display panel 100, and improving the display effect of the display panel 100.

[0057] Specifically, taking the diffraction range of the reflected light along the long side direction Y or the wide side direction X of the substrate 1 as a, the wavelength of the light emitted through the first color block 621 as λ, and the focal length of the inner lens structure of the display panel 100 as f as an example, the light intensity X of the light diffracted by the first color block 621 can be calculated according to the following formula:

[0058]

[0059] Since the focal length f of the display panel 100 is the same for the color blocks 620 of different colors, it can be known from the above formula (1) that the intensity X of the diffracted light after diffracting through the first color block 621 is only related to the diffraction range a. Therefore, in the embodiment of the present application, by adding a plurality of light shielding blocks 7 in the first color block 621, the diffraction range a can be adjusted, thereby adjusting the intensity of the diffracted light after diffracting through the first color block 621. For example, the intensity of the diffracted light through the first color block 621 is made the same or similar to the intensity of the diffracted light through the second color block 622, and the red, green and blue light of the same or similar intensity are fused to synthesize white light, so that the display panel 100 appears white as a whole, thereby improving the phenomenon of color separation of the display panel 100 and improving the display effect of the display panel 100.

[0060] In addition, since the viewing angle decay of the larger color block 620 is slower, the shading block 7 is filled in the larger first color block 621, and the shading block 7 can block the outgoing light of the light-emitting unit 3 in the display panel 100, thereby adjusting the luminous intensity of the outgoing light at different positions emitted through the encapsulation layer 5 and the first color block 621, so that the viewing angle decay degree of the color blocks 620 of different colors and sizes in the display panel 100 tends to be consistent, so that the front view brightness and the side view brightness of the display panel 100 are similar, thereby improving the color deviation of the display panel 100 at different viewing angles and improving the display effect of the display panel 100. Among them, the front view brightness is the brightness received by the human eye when the plane where the human eye is located is parallel to the plane where the display panel 100 is located, and the side view brightness is the brightness received by the human eye when the plane where the human eye is located is at an acute angle to the plane where the display panel 100 is located.

[0061] In some embodiments, along the long side direction Y and / or the wide side direction X of the base substrate 1, the size of the first color block 621 is larger than the size of the second color block 622, and a plurality of light shielding blocks 7 may be filled in the second color block 622. Taking the first color block 621 as a blue color block and the second color block 622 as a red color block as an example, adding a plurality of light shielding blocks 7 in the second color block 622 can reduce the diffraction range of the reflected light through the red color block, thereby increasing the light intensity of the diffracted light after diffraction through the second color block 622. Since the size of the blue color block is larger, adding a light shielding block 7 in the red color block can further increase the light intensity difference of the diffracted light through the red color block and the blue color block, thereby increasing the proportion of the light intensity of the red light, so that the overall color presented by the display panel 100 is roughly yellowish.

[0062] In the embodiment of the present application, the position and number of the shading blocks 7 can be adjusted according to actual needs, so that the display panel 100 can present the desired color, and the color of the surface of the display panel 100 can be controlled and adjusted after the ambient light is irradiated to the display panel 100.

[0063] In some embodiments, the pixel unit 10 further includes a third pixel, and the color filter layer 62 includes a third color block 623 arranged corresponding to the third pixel. Along the long side direction Y and / or the wide side direction X of the base substrate 1, the size of the second color block 622 is larger than the size of the third color block 623, and the second color block 622 includes a plurality of second hollow areas 6211 arranged at intervals. Among them, the plurality of light shielding blocks 7 fill the plurality of second hollow areas 6211.

[0064] In the present application embodiment, Figure 6 As shown, along the long side direction Y of the base substrate 1, the size of the first color block 621 is larger than the size of the second color block 622, the size of the second color block 622 is larger than the size of the third color block 623, and a plurality of shading blocks 7 are arranged in the first color block 621 and the second color block 622. By filling a plurality of light shielding blocks 7 in the first color block 621 and the second color block 622 with larger sizes, the sizes of the light-transmitting areas in the first color block 621 and the second color block 622 can be adjusted, thereby adjusting the diffraction range of the reflected light at the first color block 621 and the second color block 622, and further adjusting the intensity of the diffracted light of the reflected light at the first color block 621 and the second color block 622, which can further reduce the difference in the intensity of the diffracted light of the reflected light at the first color block 621, the second color block 622 and the third color block 623, so that the intensity of the diffracted light after the reflected light is diffracted by different color blocks 620 is similar, so that the diffracted light after diffracting by different color blocks 620 can be more integrated into white light, further increasing the color consistency of the surface of the display panel 100, improving the color separation phenomenon of the display panel 100, and improving the display effect of the display panel 100.

[0065] Among them, the number and distribution position of the shading blocks 7 in the first color block 621, and the number and distribution position of the shading blocks 7 in the second color block 622 can be set according to actual needs, such as determined according to the color and size of the first color block 621 and the second color block 622.

[0066] Optional, such as Figure 6 As shown, when the first color block 621 is a blue color block, the second color block 622 is a green color block, and the size of the blue color block along the long side direction Y of the base substrate 1 is larger than that of the green color block, the wavelength of the blue light diffracted by the blue color block is shorter, and the size of the blue color block is larger. In combination with the above formula (1), it can be seen that in order to make the light intensity of the diffracted light through the blue color block closer to the light intensity of the diffracted light through the green color block, it is necessary to reduce the diffraction range of the blue color block, so the number of light shielding blocks 7 in the blue color block can be greater than the number of light shielding blocks 7 in the green color block.

[0067] In addition, the first color block 621 can also be a blue color block, and the second color block 622 can be a red color block; or the first color block 621 can be a red color block, and the second color block 622 can be a green color block, which is not limited in the present application.

[0068] In some embodiments, such as Figure 5 As shown, the third color resist block 623 includes a plurality of second hollow areas 6211 arranged at intervals, and the number of the plurality of second hollow areas 6211 in the third color resist block 623 is less than the number of the second hollow areas 6211 in the second color resist block 622 .

[0069] In the embodiment of the present application, the number of light shielding blocks 7 in the third color blocking block 623 may be less than the number of light shielding blocks 7 in the second color blocking block 622. Figure 5 As shown, along the long side direction Y of the base substrate 1, the size of the first color block 621 is larger than the size of the second color block 622, the size of the second color block 622 is larger than the size of the third color block 623, and a plurality of shading blocks 7 are arranged in the first color block 621, the second color block 622 and the third color block 623.

[0070] A plurality of light shielding blocks 7 are provided in the first color blocking block 621, the second color blocking block 622 and the third color blocking block 623, so as to synchronously adjust the size of the light-transmitting area in the first color blocking block 621, the second color blocking block 622 and the third color blocking block 623, thereby synchronously adjusting the diffraction range of the reflected light at the first color blocking block 621, the second color blocking block 622 and the third color blocking block 623, adjusting the light intensity of the diffracted light of the reflected light at the first color blocking block 621, the second color blocking block 622 and the third color blocking block 623, and thus making the reflected light pass through the first color blocking block 621, the second color blocking block 622 and the third color blocking block The light intensity of the diffracted light after the color block 623 approaches the same light intensity value, which can further reduce the difference in the light intensity of the diffracted light of the reflected light at the first color block 621, the second color block 622 and the third color block 623, so that the light intensity of the diffracted light of the reflected light after diffracting through different color blocks 620 is similar, so that the diffracted light after diffracting through different color blocks 620 can be more fused into white light, further increasing the color consistency of the surface of the display panel 100, improving the color separation phenomenon of the display panel 100, and improving the display effect of the display panel 100. In addition, since the size of the third color block 623 along the long side direction Y of the base substrate 1 is small, the number of light shielding blocks 7 in the third color block 623 is less than the number of light shielding blocks 7 in the second color block 622, which can make the light intensity of the diffracted light through the third color block 623 change less, and further reduce the difference in the light intensity of the diffracted light of the reflected light at the first color block 621, the second color block 622 and the third color block 623.

[0071] The number and distribution position of the light-shielding blocks 7 in the first color-blocking block 621, the number and distribution position of the light-shielding blocks 7 in the second color-blocking block 622, and the number and distribution position of the light-shielding blocks 7 in the third color-blocking block 623 can all be set according to actual needs, such as according to the colors and sizes of the first color-blocking block 621, the second color-blocking block 622, and the third color-blocking block 623. In one example, the first color-blocking block 621 is a blue color-blocking block, the second color-blocking block 622 is a red color-blocking block, and the third color-blocking block 623 is a green color-blocking block. In another example, the first color-blocking block 621 is a blue color-blocking block, the second color-blocking block 622 is a green color-blocking block, and the third color-blocking block 623 is a red color-blocking block.

[0072] In some embodiments, the first color block 621 is a blue color block, the second color block 622 is a green color block, and the third color block 623 is a red color block.

[0073] In the present application embodiment, Figure 5 As shown, the first color block 621 is a blue color block, the second color block 622 is a green color block, and the third color block 623 is a red color block, and the size of the blue color block along the long side direction Y of the substrate 1 is larger than that of the green color block, and the size of the green color block along the long side direction Y of the substrate 1 is larger than that of the red color block, the number of light-shielding blocks 7 in the red color block is smaller than the number of light-shielding blocks 7 in the green color block, and the number of light-shielding blocks 7 in the green color block may also be smaller than the number of light-shielding blocks 7 in the blue color block. Specifically, since the size of the blue color block along the long side direction Y is larger than that of the green color block, and the size of the green color block is larger than that of the red color block, and the wavelength of the blue light after diffraction through the blue color block is smaller than the wavelength of the green light after diffraction through the green color block, and the wavelength of the green light is smaller than the wavelength of the red light after diffraction through the red color block, it can be seen from the above formula (1) that the number of light shielding blocks 7 in the blue color block is larger than the number of light shielding blocks 7 in the green color block, and the number of light shielding blocks 7 in the green color block is larger than the number of light shielding blocks 7 in the red color block, so that the light intensity of the diffracted light through the blue color block can be closer to the light intensity of the diffracted light through the green color block and the light intensity of the diffracted light through the red color block, so that the diffracted light after diffraction through different color blocks 620 can be more fused into white light, further increasing the color consistency of the surface of the display panel 100, improving the color separation phenomenon of the display panel 100, and improving the display effect of the display panel 100.

[0074] In some embodiments, the pixel unit 10 includes a first pixel and a second pixel, the color film layer 62 includes a first color block 621 corresponding to the first pixel, and a second color block 622 corresponding to the second pixel, the wavelength of the first light emitted through the first color block 621 is greater than the wavelength of the second light emitted through the second color block 622, and the second color block 622 includes a plurality of second hollow areas 6211 arranged at intervals.

[0075] In the embodiment of the present application, the first pixel may be a red pixel, the second pixel may be a green pixel, the first color block 621 is a red color block, and the second color block 622 is a green color block. The light emitted through the red color block is red light, and the light emitted through the green color block is green light, and the wavelength of red light is greater than that of green light. According to formula (1), when the size of the first color block 621 and the second color block 622 are similar, the light intensity of the light diffracted by the first color block 621 is greater than the light intensity of the light diffracted by the second color block 622. Therefore, filling a plurality of light shielding blocks 7 in the second color block 622 can reduce the diffraction range of the light passing through the second color block 622, thereby increasing the intensity of the diffracted light passing through the second color block 622, and reducing the difference in the intensity of the diffracted light of the reflected light at the first color block 621 and the second color block 622, so that the intensity of the diffracted light after the reflected light is diffracted by different color blocks 620 is similar, so that the diffracted light after diffracting by different color blocks 620 can be more fused into white light, thereby increasing the color consistency of the surface of the display panel 100, realizing the control and adjustment of the color of the surface of the display panel 100 after the ambient light is irradiated to the display panel 100, and improving the color separation phenomenon of the display panel 100.

[0076] Furthermore, the pixel unit 10 also includes a third pixel, the color film layer 62 includes a third color block 623 corresponding to the third pixel, the wavelength of the second light emitted through the second color block 622 is greater than the wavelength of the third light emitted through the third color block 623, and the second color block 622 includes a plurality of second hollow areas 6211 arranged at intervals. The first color block 621 may be a red color block, the second color block 622 may be a green color block, and the third color block 623 may be a blue color block. Since the wavelength of blue light emitted through the third color block 623 is the smallest, when the sizes of the first color block 621, the second color block 622, and the third color block 623 are approximately equal, it can be seen from formula (1) that the intensity of light diffracted through the third color block 623 is the smallest. Therefore, adding a shading block 7 to the first color block 621 and the second color block 622 can make the intensity of diffracted light after the reflected light is diffracted through different color blocks 620 similar, so that the diffracted light after diffracting through different color blocks 620 can be more integrated into white light, further increasing the color consistency of the surface of the display panel 100.

[0077] In addition, a light shielding block 7 may be added to the third color block 623 corresponding to the smallest wavelength to synchronously adjust the light intensity of the light passing through the first color block 621, the second color block 622, and the third color block 623. The position and number of the light shielding blocks 7 in each color block 620 may be adjusted according to actual needs, such as adjusting according to the color that the display panel 100 needs to present, and the present application does not limit this.

[0078] In some embodiments, Figure 4 and Figure 5 As shown, a plurality of light shielding blocks 7 are manufactured on the same layer as the black matrix layer 61 .

[0079] In the embodiment of the present application, the plurality of light shielding blocks 7 and the black matrix layer 61 are made in the same layer, that is, the plurality of light shielding blocks 7 and the black matrix layer 61 can be made of the same material and formed after patterning using the same mask, which can simplify the production process of the plurality of light shielding blocks 7 and the black matrix layer 61, reduce the complexity of the production process, and reduce the production cost of the display panel 100. Optionally, the material of the black matrix layer 61 and the plurality of light shielding blocks 7 can be chromium or carbon black. Specifically, the preparation process of the plurality of light shielding blocks 7 and the black matrix layer 61 can be to form a black matrix layer 61 on the side of the encapsulation layer 5 away from the base substrate 1, expose and develop the black matrix layer 61 through a first mask, and then etch to form a plurality of first hollow areas 610 and a plurality of light shielding blocks 7 placed in the first hollow areas 610.

[0080] In some embodiments, Figure 6 and Figure 7 As shown, the first color block 621 is rectangular, and along the long side direction of the first color block 621, the size of the first color block 621 is larger than the sizes of the second color block 622 and the third color block 623, and along the long side direction of the first color block 621, the first color block 621 includes a first end area 6201, a middle area 6202 and a second end area 6203, the number of light-shielding blocks 7 located in the first end area 6201 is larger than the number of light-shielding blocks 7 located in the middle area 6202, and the number of light-shielding blocks 7 located in the second end area 6203 is larger than the number of light-shielding blocks 7 located in the middle area 6202.

[0081] In the embodiment of the present application, along the long side direction of the first color block 621, the number of shading blocks 7 in the first end area 6201 and the second end area 6203 is greater than the number of shading blocks 7 located in the middle area 6202, which can reduce the directionality problem of reflected light caused by the different lengths of the long side and the wide side of the first color block 621, and can adjust the problem of inconsistent viewing angle decay in the long side direction and the viewing angle decay in the short side direction of the first color block 621, so that the long side direction and the short side direction of the first color block 621 have the same degree of viewing angle decay, thereby reducing the probability of color deviation of the display panel 100 and improving the display effect of the display panel 100.

[0082] Optional, such as Figure 6 As shown, the number of shading blocks 7 in the first end area 6201 can be 3, the number of shading blocks 7 in the middle area 6202 can be 1, and the number of shading blocks 7 in the second end area 6203 can be 3, so that the long side direction and the short side direction of the first color block 621 have the same degree of viewing angle decay.

[0083] Optionally, the distribution number of shading blocks 7 in the second color block 622 and the third color block 623 can also be adjusted according to the size of the second color block 622 and the third color block 623, so as to adjust the degree of viewing angle decay in the long side direction and the viewing angle decay in the short side direction of the second color block 622 and the third color block 623. By adjusting the viewing angle decay in different directions in a single color block 620 through the shading block 7, the viewing angle decay in different directions of the display panel 100 as a whole can be adjusted, thereby further reducing the probability of color deviation of the display panel 100 and improving the display effect of the display panel 100.
