The light-emitting functional layer 03 includes a light-emitting unit 031 located in the opening and corresponding to the opening one by one. The shading functional layer is located on the side of the light-emitting functional layer 03 away from the substrate layer 01, and includes a plurality of shading modules 04. The multi-color filter functional layer 05 is located on the side of the shading module 04 away from the substrate layer 01. The multi-color filter functional layer 05 allows the light emitted by each light-emitting unit 031 to pass through. The multi-color filter functional layer 05 is purple, so that the display panel has a problem of purple hue, which seriously affects the user experience. Therefore, the present application provides a display panel and a display device to improve the problem of purple hue in the display effect.

[0049] like Figure 2 and Figure 3 As shown, according to an embodiment of the present application, a display panel 1 is proposed, which includes a substrate 11, a pixel defining layer 12, a light emitting layer 13 and a light regulating layer 14. The pixel defining layer 12 is located on one side of the substrate 11 and includes a plurality of pixel openings 121. The light emitting layer 13 is located on one side of the substrate 11 and includes a plurality of light emitting units, which are located in the pixel openings 121, and the plurality of light emitting units include a first light emitting unit 131, a second light emitting unit 132 and a third light emitting unit 133. The light regulating layer 14 is located on the side of the light emitting layer 13 away from the substrate 11, and includes a plurality of filter areas, including a first filter area 141, a second filter area 142 and a third filter area 143 corresponding to the first light emitting unit 131, the second light emitting unit 132 and the third light emitting unit 133 respectively. The light regulating layer 14 also includes a shading area 144 located between two adjacent filter areas, wherein the first filter area 141 includes a monochromatic filter portion 145, and the monochromatic filter portion 145 allows the light emitted by the first light emitting unit 131 to pass through; the second filter area 142, the third filter area 143 and the shading area 144 all include a multicolor filter portion 146, and the transmittance of the multicolor filter portion 146 to the light emitted by the second light emitting unit 132 and the third light emitting unit 133 is higher than the transmittance to the light emitted by the first light emitting unit 131; the shading area 144 also includes a monochromatic filter portion 145 stacked with the multicolor filter portion 146.

[0050] The display panel 1 provided in the present application includes a substrate 11, a pixel defining layer 12, a light emitting layer 13 and a light regulating layer 14. The pixel defining layer 12 is located on one side of the substrate 11 and includes a plurality of pixel openings 121. The light emitting layer 13 includes a plurality of light emitting units, and the light emitting units correspond to the pixel openings 121 one by one. The pixel openings 121 are used to define the light emitting units. The plurality of light emitting units include a first light emitting unit 131, a second light emitting unit 132 and a third light emitting unit 133. The light emitting colors of the first light emitting unit 131, the second light emitting unit 132 and the third light emitting unit 133 are different. Specifically, the light emitting color of each light emitting unit can be any one of red, green and blue. The display panel 1 also includes a light regulating layer 14, which is located on the side of the light emitting layer 13 away from the substrate 11, and is used to regulate the light emitting effect of the display panel 1. The light regulating layer 14 includes a first filter area 141, a second filter area 142, a third filter area 143 and a shading area 144. The first filter area 141 corresponds to the first light-emitting unit 131, is located at a side of the first light-emitting unit 131 away from the substrate 11, and the orthographic projection of the first light-emitting unit 131 on the substrate 11 is located within the orthographic projection of the first filter area 141 on the substrate 11; the second filter area 142 corresponds to the second light-emitting unit 132, is located at a side of the second light-emitting unit 132 away from the substrate 11, and the orthographic projection of the second light-emitting unit 132 on the substrate 11 is located within the orthographic projection of the second filter area 142 on the substrate 11; the third filter area 143 corresponds to the third light-emitting unit 133, is located at a side of the third light-emitting unit 133 away from the substrate 11, and the orthographic projection of the third light-emitting unit 133 on the substrate 11 is located within the orthographic projection of the third filter area 143 on the substrate 11. The light shielding area 144 is located between any two adjacent filter areas, and is used to improve the problem that the light emitted from the adjacent filter areas is prone to crosstalk.

[0051] In the display panel 1 provided in the present application, the first filter area 141 includes a monochrome filter portion 145, which only transmits light of one color. Specifically, the monochrome filter portion 145 allows the light emitted by the first light-emitting unit 131 to pass through, but does not allow the light emitted by the second light-emitting unit 132 and the third light-emitting unit 133 to pass through. Therefore, the light purity of the display panel 1 can be improved through the monochrome filter portion 145, and the reflectivity of the first filter area 141 to the light can be reduced, thereby improving the display effect. The second filter area 142, the third filter area 143 and the shading area 144 all include a multicolor filter portion 146. The transmittance of the multicolor filter portion 146 to the light emitted by the second light-emitting unit 132 and the third light-emitting unit 133 is higher than the transmittance to the light emitted by the first light-emitting unit 131, that is, a large amount of light emitted by the second light-emitting unit 132 and the third light-emitting unit 133 can pass through the multicolor filter portion 146, and only a small part of the light emitted by the first light-emitting unit 131 can pass through the multicolor filter portion 146, so that the second filter area 142 can reduce the reflectivity of light with the same color as the light emitted by the first light-emitting unit 131, and improve the light output purity of the display panel 1. The light shielding area 144 also includes a monochromatic filter 145 stacked with the multicolor filter 146. The multicolor filter 146 can intercept the light emitted by the first light emitting unit 131 to a certain extent, and the monochromatic filter 145 can intercept the light emitted by the second light emitting unit 132 and the third light emitting unit 133, so that the light shielding area 144 has the function of intercepting the light emitted by the first light emitting unit 131, the second light emitting unit 132 and the third light emitting unit 133 to improve the cross-light problem. In the display panel 1, by providing the light regulating layer 14, the reflectivity of the display panel 1 to the light can be reduced, and the purity of the light output can be improved, thereby improving the display effect. The light regulating layer 14 in the present application includes a monochromatic filter portion 145 and a multicolor filter portion 146. The monochromatic filter portion 145 is used to filter the light emitted by the first light-emitting unit 131, and the multicolor filter portion 146 is mainly used to filter the light emitted by the second light-emitting unit 132 and the third light-emitting unit 133. Compared with the multicolor filter functional layer having a high transmittance for the light emitted by the first light-emitting unit 131, the second light-emitting unit 132 and the third light-emitting unit 133, the light regulating layer 14 can improve the problem of purple hue in the display effect of the display panel 1 by separately designing parameters for the monochromatic filter portion 145 and the multicolor filter portion 146.

[0052] Specifically, the parameters of the monochromatic filter 145 and the multicolor filter 146 can be set according to the actual needs of the display panel 1 in combination with the parameters of other structures in the display panel 1. The parameters of the monochromatic filter 145 and the multicolor filter 146 mainly include thickness, transmittance, etc. The light regulation layer 14 provided in the present application can make the a value range of the hue of the display panel 1 be -2 to 0, and the b value range be -3 to 0, thereby effectively improving the problem of the hue of the display panel 1 being purple.

[0053] Specifically, the size of the monochromatic filter portion 145 along the thickness direction of the substrate 11 ranges from 2 μm to 4 μm; the size of the multicolor filter portion 146 along the thickness direction of the substrate 11 ranges from 2 μm to 4 μm. The size of the monochromatic filter portion 145 along the thickness direction of the substrate 11 and the size of the multicolor filter portion 146 along the thickness direction of the substrate 11 may be the same or different, and the specific size needs to be set according to actual needs.

[0054] Specifically, each light emitting unit can emit any one of red light, green light and blue light, the wavelength range of red light is 580nm-780nm; the wavelength range of green light is 480nm-580nm; the wavelength range of blue light is 380nm-480nm.

[0055] In a feasible implementation manner, the transmittance of the multi-color filter 146 to the light emitted by the first light-emitting unit 131 is less than or equal to 20%.

[0056] In the above embodiment, the transmittance of the multi-color filter portion 146 to the light emitted by the first light-emitting unit 131 is less than or equal to 20%, so that the light emitted by the first light-emitting unit 131 can be well intercepted, and the shading portion can further shadingly improve the light crosstalk problem between adjacent light-emitting units.

[0057] Specifically, the shading area 144 includes a multicolor filter portion 146 and a monochrome filter portion 145 stacked along the thickness direction of the substrate 11. Any one of the red light, green light and blue light can only mostly pass through one of the multicolor filter portion 146 and the monochrome filter portion 145, and cannot mostly pass through the other, thereby achieving a shading effect.

[0058] Specifically, when the specific parameters of different multicolor filters 146 are different, the transmittances of the light emitted by the first light-emitting unit 131 by the different multicolor filters 146 are different, and when the wavelengths of the light emitted by the first light-emitting unit 131 are different, the transmittances of the light emitted by the first light-emitting unit 131 by the multicolor filters 146 are different. The transmittance of the light emitted by the first light-emitting unit 131 by the multicolor filters 146 may be 1%, 3%, 4%, 8%, 9%, 10%, 15%, 16%, 19% or 20%.

[0059] In a possible implementation, Figure 4 As shown, the first light-emitting unit 131 is a green light-emitting unit, and the material of the monochrome filter portion 145 includes colloid and green dye; the second light-emitting unit 132 is a blue light-emitting unit, the third light-emitting unit 133 is a red light-emitting unit, and the material of the multicolor filter portion 146 includes colloid, red dye and blue dye. The transmittance of the multicolor filter portion 146 to the light emitted by the second light-emitting unit 132 is in the range of 60%-65%, and the transmittance of the multicolor filter portion 146 to the light emitted by the third light-emitting unit 133 is in the range of 60%-70%.

[0060] In the above embodiment, when the color of the light emitted by the first light emitting unit 131 is green, the monochromatic filter 145 is a green filter for filtering green light, and the material of the monochromatic filter 145 includes colloid and green dye, and the monochromatic filter 145 has a higher transmittance to green light. Specifically, the transmittance of the monochromatic filter 145 to green light can range from 40% to 70%, thereby reducing the power consumption of the display panel 1. The second light emitting unit 132 is a blue light emitting unit for emitting blue light, and the third light emitting unit 133 is a red light emitting unit for emitting red light. The material of the multicolor filter 146 includes colloid, red dye and blue dye, so the transmittance of the multicolor filter 146 to red light and blue light is higher than the transmittance to green light.

[0061] Specifically, the transmittance of the multicolor filter 146 to the light emitted by the second light emitting unit 132 is in the range of 60%-65%, the transmittance of the multicolor filter 146 to the light emitted by the third light emitting unit 133 is in the range of 60%-70%, and the transmittance of the multicolor filter 146 to the light emitted by the first light emitting unit 131 is less than or equal to 20%. Therefore, the transmittance of the multicolor filter 146 to the light emitted by the second light emitting unit 132 and the third light emitting unit 133 is high, and the transmittance to the light emitted by the first light emitting unit 131 is low, so that when the multicolor filter 146 and the monochromatic filter 145 are stacked, a light shielding function can be achieved. In addition, the transmittance of the multicolor filter 146 to the light emitted by the second light emitting unit 132 and the third light emitting unit 133 is high, which can further reduce the power consumption of the display panel 1.

[0062] In another possible implementation, if Figure 5 As shown, the first light-emitting unit 131 is a blue light-emitting unit, and the material of the monochrome filter portion 145 includes colloid and blue dye; the second light-emitting unit 132 is a red light-emitting unit, the third light-emitting unit 133 is a green light-emitting unit, and the material of the multicolor filter portion 146 includes colloid, red dye and green dye. The transmittance of the multicolor filter portion 146 to the light emitted by the second light-emitting unit 132 is in the range of 60%-70%, and the transmittance of the multicolor filter portion 146 to the light emitted by the third light-emitting unit 133 is in the range of 55%-60%.

[0063] In the above embodiment, when the color of the light emitted by the first light emitting unit 131 is blue, the monochromatic filter 145 is a blue filter for filtering blue light, and the material of the monochromatic filter 145 includes colloid and blue dye, and the monochromatic filter 145 has a high transmittance to blue light. Specifically, the transmittance of the monochromatic filter 145 to blue light is in the range of 45-85%, thereby reducing the power consumption of the display panel 1. The second light emitting unit 132 is a red light emitting unit for emitting red light, and the third light emitting unit 133 is a green light emitting unit for emitting green light. The material of the multicolor filter 146 includes colloid, red dye and green dye, so the transmittance of the multicolor filter 146 to red light and green light is higher than the transmittance to blue light.

[0064] Specifically, the transmittance of the multicolor filter 146 to the light emitted by the second light emitting unit 132 is in the range of 60%-70%, the transmittance of the multicolor filter 146 to the light emitted by the third light emitting unit 133 is in the range of 55%-60%, and the transmittance of the multicolor filter 146 to the light emitted by the first light emitting unit 131 is less than or equal to 20%. Therefore, the transmittance of the multicolor filter 146 to the light emitted by the second light emitting unit 132 and the third light emitting unit 133 is high, and the transmittance to the light emitted by the first light emitting unit 131 is low, so that when the multicolor filter 146 and the monochromatic filter 145 are stacked, a light shielding function can be achieved. In addition, the transmittance of the multicolor filter 146 to the light emitted by the second light emitting unit 132 and the third light emitting unit 133 is high, which can further reduce the power consumption of the display panel 1.

[0065] In another possible implementation, Figure 5As shown, the first light-emitting unit 131 is a red light-emitting unit, and the material of the monochrome filter portion 145 includes colloid and red dye; the second light-emitting unit 132 is a blue light-emitting unit, the third light-emitting unit 133 is a green light-emitting unit, and the material of the multicolor filter portion 146 includes colloid, blue dye and blue dye. The transmittance of the multicolor filter portion 146 to the light emitted by the second light-emitting unit 132 is in the range of 60%-65%, and the transmittance of the multicolor filter portion 146 to the light emitted by the third light-emitting unit 133 is in the range of 55%-60%.

[0066] In the above embodiment, when the color of the light emitted by the first light emitting unit 131 is red, the monochromatic filter 145 is a red filter for filtering red light, and the material of the monochromatic filter 145 includes colloid and red dye, and the monochromatic filter 145 has a higher transmittance to red light. Specifically, the transmittance of the monochromatic filter 145 to red light is in the range of 45-85%, thereby reducing the power consumption of the display panel 1. The second light emitting unit 132 is a blue light emitting unit for emitting blue light, and the third light emitting unit 133 is a green light emitting unit for emitting green light. The material of the multicolor filter 146 includes colloid, blue dye and green dye, so the transmittance of the multicolor filter 146 to blue light and green light is higher than the transmittance to red light.

[0067] Specifically, the transmittance of the multicolor filter 146 to the light emitted by the second light emitting unit 132 is in the range of 60%-65%, the transmittance of the multicolor filter 146 to the light emitted by the third light emitting unit 133 is in the range of 55%-60%, and the transmittance of the multicolor filter 146 to the light emitted by the first light emitting unit 131 is less than or equal to 20%. Therefore, the transmittance of the multicolor filter 146 to the light emitted by the second light emitting unit 132 and the third light emitting unit 133 is high, and the transmittance to the light emitted by the first light emitting unit 131 is low, so that when the multicolor filter 146 and the monochromatic filter 145 are stacked, a light shielding function can be achieved. In addition, the transmittance of the multicolor filter 146 to the light emitted by the second light emitting unit 132 and the third light emitting unit 133 is high, which can further reduce the power consumption of the display panel 1.

Specifically, when CI Pigment Red is used, any one of the numbers 48: 1, 122, 177, 224, 242, 269, 254, 291, 295, and 296 may be used. The color of the blue dye may be one of CI pigment blue, CI solvent blue, CI acid blue, CI direct blue, CI disperse blue, CI basic blue, and CI medium blue in the Colour Index (CI).

Specifically, when CI Pigment Blue is used, any one of numbers 7, 10, 36, 37, 38, 42, 58, 59, 62, 63, 64, 65, and 66 may be used.

[0069] In a possible implementation, Figures 4 to 6 As shown, the first filter region 141 further includes a transparent flat portion 147 stacked with the monochromatic filter portion 145 , and the second filter region 142 and the third filter region 143 further include a transparent flat portion 147 stacked with the multicolor filter portion 146 .

[0070] In the above embodiment, the step difference between the film layers is reduced by providing a transparent flat portion 147 in the light regulating layer 14. Specifically, since the light shielding area 144 includes a multicolor filter portion 146 and a monochromatic filter portion 145 stacked along the thickness direction of the substrate 11, the thickness of the light shielding area 144 is relatively thick. By providing a transparent flat portion 147 in the first filter area 141, the second filter area 142, and the third filter area 143, the step difference between the light shielding area 144 and the first filter area 141, the step difference between the light shielding area 144 and the second filter area 142, and the step difference between the light shielding area 144 and the third filter area 143 can be reduced, thereby improving the flatness of the surface of the light regulating layer 14 on the side away from the substrate 11, thereby helping to improve the preparation yield of subsequent film layers.

[0071] In the above embodiment, the monochromatic filter portion 145 in the first filter region 141 may be located on the side of the transparent flat portion 147 away from the substrate 11, or the monochromatic filter portion 145 in the first filter region 141 may be located on the side of the transparent flat portion 147 close to the substrate 11. The multicolor filter portion 146 in the second filter region 142 may be located on the side of the transparent flat portion 147 away from the substrate 11, or the multicolor filter portion 146 in the second filter region 142 may be located on the side of the transparent flat portion 147 close to the substrate 11. The multicolor filter portion 146 in the third filter region 143 may be located on the side of the transparent flat portion 147 away from the substrate 11, or the multicolor filter portion 146 in the third filter region 143 may be located on the side of the transparent flat portion 147 close to the substrate 11. In the light shielding area 144 , the multicolor filter portion 146 may be located on a side of the monochromatic filter portion 145 close to the substrate 11 , or the multicolor filter portion 146 may be located on a side of the monochromatic filter portion 145 far from the substrate 11 .

[0072] Specifically, in order to simplify the preparation process and reduce the number of masking times, the light regulating layer 14 can be prepared by the following three preparation methods.

[0073] The first implementation method includes: Figures 4 to 6 As shown, a transparent flat layer is first prepared and patterned, the portion of the transparent flat layer located in the light-shielding area 144 is removed, and the portion of the transparent flat layer located in the first filter area 141, the second filter area 142 and the third filter area 143 is retained to form a transparent flat portion 147. Then a monochromatic filter layer is prepared and patterned, the portion of the monochromatic filter layer located in the second filter area 142 and the third filter area 143 is removed, and the portion of the monochromatic filter layer located in the first filter area 141 and the light-shielding area 144 is retained to form a monochromatic filter portion 145.

[0074] In this embodiment, if Figures 4 to 6 As shown, the light regulating layer 14 includes a first regulating layer 148 and a second regulating layer 149 stacked in a direction away from the substrate 11, the first regulating layer 148 includes a monochrome filter portion 145 located in the shading area 144 and a transparent flat portion 147 located outside the shading area 144; the second regulating layer 149 includes a monochrome filter portion 145 located in the first filter area 141 and a multicolor filter portion 146 located outside the first filter area 141.

[0075] That is, in the first filter area 141, the monochromatic filter portion 145 is located on the side of the transparent flat portion 147 away from the substrate 11; in the light shielding area 144, the multicolor filter portion 146 is located on the side of the monochromatic filter portion 145 away from the substrate 11; in the second filter area 142, the multicolor filter portion 146 is located on the side of the transparent flat portion 147 away from the substrate 11; in the third filter area 143, the multicolor filter portion 146 is located on the side of the transparent flat portion 147 away from the substrate 11. The multicolor filter portion 146 in the second filter area 142 is integrally formed with the multicolor filter portion 146 in the adjacent light shielding area 144, and the multicolor filter portion 146 in the third filter area 143 can be integrally formed with the multicolor filter portion 146 in the adjacent light shielding area 144.

[0076] In this embodiment, the number of patterned masks is small, thereby simplifying the preparation process and saving preparation costs.

[0077] In the above embodiment, the surface of the transparent flat portion 147 facing away from the substrate 11 may be flush with the surface of the monochromatic filter portion 145 facing away from the substrate 11 , so as to improve the flatness of the first regulating layer 148 .

[0078] The second implementation method includes: Figure 7 As shown, a transparent flat layer is first prepared and patterned, the portion of the transparent flat layer located in the light-shielding area 144 is removed, and the portion of the transparent flat layer located in the first filter area 141, the second filter area 142 and the third filter area 143 is retained to form a transparent flat portion 147. Then a multicolor filter layer is formed and patterned, the portion of the multicolor filter layer located in the first filter area 141 is removed, and the portion of the multicolor filter layer located in the light-shielding area 144, the second filter area 142 and the third filter area 143 is retained to form a multicolor filter portion 146. Then a monochromatic filter layer is prepared and patterned, the portion of the monochromatic filter layer located in the second filter area 142 and the third filter area 143 is removed, and the portion of the monochromatic filter layer located in the first filter area 141 and the light-shielding area 144 is retained to form a monochromatic filter portion 145.

[0079] In this embodiment, if Figure 7 As shown, the light regulating layer 14 includes a first regulating layer 148 and a second regulating layer 149 stacked in a direction away from the substrate 11, the first regulating layer 148 includes a multicolor filter portion 146 located in the shading area 144 and a transparent flat portion 147 located outside the shading area 144; the second regulating layer 149 includes a monochrome filter portion 145 located in the first filter area 141 and the shading area 144 and a multicolor filter portion 146 located in the second filter area 142 and the third filter area 143.

[0080] That is, in the first filter area 141, the monochromatic filter portion 145 is located on the side of the transparent flat portion 147 away from the substrate 11; in the light shielding area 144, the monochromatic filter portion 145 is located on the side of the multicolor filter portion 146 away from the substrate 11; in the second filter area 142, the multicolor filter portion 146 is located on the side of the transparent flat portion 147 away from the substrate 11; in the third filter area 143, the multicolor filter portion 146 is located on the side of the transparent flat portion 147 away from the substrate 11. The monochromatic filter portion 145 in the first filter area 141 and the monochromatic filter portion 145 in the adjacent light shielding area 144 can be integrally formed.

[0081] In this embodiment, the number of patterned masks is small, thereby simplifying the preparation process and saving preparation costs.

[0082] In the above embodiment, the surface of the transparent flat portion 147 facing away from the substrate 11 may be flush with the surface of the multi-color filter portion 146 facing away from the substrate 11 , so as to improve the flatness of the first regulating layer 148 .

[0083] The third implementation method includes: Figure 8 As shown, a monochromatic filter layer is first prepared and patterned, the portion of the monochromatic filter layer located in the second filter region 142 and the third filter region 143 is removed, and the portion of the monochromatic filter layer located in the first filter region 141 and the light-shielding region 144 is retained to form a monochromatic filter portion 145. Then, a transparent flat layer is prepared and patterned, the portion of the transparent flat layer located in the light-shielding region 144 is removed, and the portion of the transparent flat layer located in the first filter region 141, the second filter region 142, and the third filter region 143 is retained to form a transparent flat portion 147. Then, a multicolor filter layer is formed and patterned, the portion of the multicolor filter layer located in the first filter region 141 is removed, and the portion of the multicolor filter layer located in the light-shielding region 144, the second filter region 142, and the third filter region 143 is retained to form a multicolor filter portion 146.

[0084] In this embodiment, if Figure 8 As shown, the light regulating layer 14 includes a first regulating layer 148 and a second regulating layer 149 which are stacked in a direction away from the substrate 11. The first regulating layer 148 includes a monochromatic filter portion 145 located in the shading area 144 and the first filter area 141, and a transparent flat portion 147 located outside the shading area 144 and the first filter area 141; the second regulating layer 149 includes a multicolor filter portion 146 located in the second filter area 142, the third filter area 143 and the shading area 144, and a transparent flat portion 147 located in the first filter area 141.

[0085] That is, in the first filter area 141, the transparent flat portion 147 is located at the side of the monochromatic filter portion 145 away from the substrate 11; in the light shielding area 144, the multicolor filter portion 146 is located at the side of the monochromatic filter portion 145 away from the substrate 11; in the second filter area 142, the multicolor filter portion 146 is located at the side of the transparent flat portion 147 away from the substrate 11; in the third filter area 143, the multicolor filter portion 146 is located at the side of the transparent flat portion 147 away from the substrate 11. The multicolor filter portion 146 in the second filter area 142 is integrally formed with the multicolor filter portion 146 in the adjacent light shielding area 144, the multicolor filter portion 146 in the third filter area 143 can be integrally formed with the multicolor filter portion 146 in the adjacent light shielding area 144, and the monochromatic filter portion 145 in the first filter area 141 can be integrally formed with the monochromatic filter portion 145 in the adjacent light shielding area 144.

[0086] In this embodiment, the number of patterned masks is small, thereby simplifying the preparation process and saving preparation costs.

[0087] In the above embodiment, the transparent flat portion 147 located in the first filter area 141 can be prepared using two preparation processes together with the transparent flat portion 147 located in the second filter area 142 and the third filter area 143, so that during the preparation, the surface of the transparent flat portion 147 located in the first regulating layer 148 facing away from the substrate 11 is flush with the surface of the monochromatic transparent portion facing away from the substrate 11, and the thickness of the transparent flat portion 147 located in the second regulating layer 149 is the same as the thickness of the multi-color filter portion 146, thereby improving the uniformity of the film thickness of the light regulating layer 14.

[0088] In a possible implementation, Fig. 9 As shown, the first filter zone 141 also includes a transparent flat portion 147 stacked with the monochromatic filter portion 145, the second filter zone 142 includes at least two layers of multicolor filter portions 146 stacked along the thickness direction of the substrate 11, and the third filter zone 143 includes two layers of multicolor filter portions 146 stacked along the thickness direction of the substrate 11.

[0089] In the above embodiment, the first filter region 141 further includes a transparent flat portion 147 stacked with the monochromatic filter portion 145 to reduce the thickness difference between the first filter region 141 and the light shielding region 144. The second filter region 142 includes at least two layers of multicolor filter portions 146 stacked along the thickness direction of the substrate 11, and the third filter region 143 includes two layers of multicolor filter portions 146 stacked along the thickness direction of the substrate 11 to reduce the difference between the second filter region 142 and the light shielding region 144 and the difference between the third filter region 143 and the light shielding region 144.

[0090] In the above embodiment, by respectively providing a multi-layer stacked multi-color filter portion 146 on the second filter layer and the third filter layer, the thickness range of the multi-color filter portion 146 can be increased to further enhance the light control capability.

[0091] In a possible implementation, Figure 8 and Fig. 9 As shown, the outer boundary of the orthographic projection of the shading area 144 on the substrate 11 is located within the outer boundary of the pixel defining layer 12 on the substrate 11, and the distance between the outer boundary of the orthographic projection of the shading area 144 on the substrate 11 and the outer boundary of the pixel defining layer 12 on the substrate 11 is D, 1μm≤D≤8μm.

[0092] In the above embodiment, the outer boundary of the orthographic projection of the light shielding area 144 on the substrate 11 is located within the outer boundary of the pixel defining layer 12 on the substrate 11, that is, the orthographic projection of the light shielding area 144 on the substrate 11 is located within the orthographic projection of the pixel defining layer 12 on the substrate 11, and the outer boundary of the orthographic projection of the light shielding area 144 on the substrate 11 does not overlap with the outer boundary of the orthographic projection of the pixel defining layer 12 on the substrate 11. This can prevent the light shielding area 144 from blocking the pixel opening 121 and affecting the light emitting area of ​​the light emitting unit.

[0093] Specifically, the distance between the outer boundary of the orthographic projection of the light shielding area 144 on the substrate 11 and the outer boundary of the pixel defining layer 12 on the substrate 11 is D, 1μm≤D≤8μm, and due to the limitation of the manufacturing process precision, the value of D fluctuates within the range of 1μm-8μm. D can be specifically 1μm, 2μm, 3μm, 4μm, 5μm, 6μm, 7μm or 8μm.

[0094] In a possible implementation, Figure 8 , Fig. 9 As shown, the display panel 1 further includes a touch layer 15 , which is located between the light-emitting layer 13 and the light-regulating layer 14 . The touch layer 15 includes a metal pattern portion, and the orthographic projection of the shading area 144 on the substrate 11 covers the orthographic projection of the metal pattern portion on the substrate 11 .

[0095] In the above embodiment, the display panel 1 is a touch display panel 1, and the touch layer 15 is located between the light-emitting layer 13 and the light regulating layer 14. The metal pattern portion in the touch layer 15 is shielded by the shading area 144 in the light regulating layer 14, thereby reducing the probability of light being reflected by the metal pattern portion, that is, reducing the reflectivity of the touch layer 15 and the display panel 1, thereby improving the performance of the display panel 1.

[0096] Specifically, when the display panel 1 is in a dark state, in order to ensure the dark state effect, it is necessary to reduce the reflectivity of the display panel 1 to external light. By shielding the metal pattern portion with the shielding area, the probability of external light irradiating the metal pattern portion can be reduced, thereby reducing the reflectivity of the display panel 1.

[0097] In a possible implementation, Figure 8 , Fig. 9 and Fig.10 As shown, the touch layer 15 includes a first metal layer 151 and a second metal layer 152 stacked in a direction away from the substrate 11, the first metal layer 151 includes a first touch trace 153, the second metal layer 152 includes a touch electrode 154 and a second touch trace 155, and the metal pattern portion includes the first touch trace 153, the touch electrode 154 and the second touch trace 155.

[0098] In the above embodiment, the touch layer 15 includes a first metal layer 151 and a second metal layer 152. The first metal layer 151 and the second metal layer 152 have a high reflectivity to light, so that they are easy to reflect light and affect the display effect of the display panel 1. The touch electrodes 154 include first touch electrodes 1541 and second touch electrodes 1542 arranged in an array. The first touch electrodes 1541 adjacent to each other in the column direction are connected by first touch wires 153 extending along the column direction, and the second touch electrodes 1542 adjacent to each other in the row direction are connected by second touch wires 155 extending along the row direction.

[0099] Specifically, the first touch electrode 1541 and the second touch electrode 1542 are both in a mesh structure, the mesh structure includes a metal entity portion and a hollow portion enclosed by the metal entity portion, and the orthographic projection of the mesh structure on the substrate 11 includes the orthographic projection of the metal entity portion on the substrate 11. The orthographic projection of the metal pattern portion on the substrate 11 is located within the orthographic projection of the light shielding area 144 on the substrate 11, including: the orthographic projection of the metal entity portion on the substrate 11 is located within the orthographic projection of the light shielding area 144 on the substrate 11, the orthographic projection of the first touch wiring 153 on the substrate 11 is located within the orthographic projection of the light shielding area 144 on the substrate 11, and the orthographic projection of the second touch wiring 155 on the substrate 11 is located within the orthographic projection of the light shielding area 144 on the substrate 11.

[0100] In the above embodiment, by setting the orthographic projection of the metal pattern portion on the substrate 11 within the orthographic projection of the shading area 144 on the substrate 11, the shading area 144 can effectively block the external light incident into the display panel 1 from continuing to be incident on the metal pattern portion, thereby reducing the reflectivity of the metal pattern portion to light.

[0101] Specifically, the portion of the light shielding layer located at the first regulating layer 148 may directly contact the surface of the touch layer 15 which is away from the substrate 11 , thereby further reducing the probability of light being incident on the metal pattern portion.

[0102] In a possible implementation, Figures 3 to 9 As shown, the display panel 1 includes a plurality of first electrodes 16 located on the surface of the side of the substrate 11 facing the light-emitting layer 13, and the plurality of first electrodes 16 are arranged at intervals. The display panel 1 also includes a second electrode 17 and an encapsulation layer 18 sequentially arranged on the side of the light-emitting layer 13 away from the substrate 11. The encapsulation layer 18 may include a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer stacked in a direction away from the substrate 11, wherein the material of the first encapsulation layer and the third encapsulation layer may include an inorganic material, and the inorganic material has a good performance layer for isolating water and oxygen, and can play a good encapsulation role. The material of the second encapsulation layer may include an organic material, and the organic material has a strong fluidity, and can play a good flattening role.

[0103] In a possible implementation, Figures 3 to 9 As shown, the pixel defining layer 12 is made of black organic material.

[0104] In a possible implementation, Fig.11 As shown, in order to improve the problem of the purple hue of the display panel 1, the color of the pixel defining layer 12 can also be changed, and a green organic material can be used to form a green pixel defining layer 12, so that the reflectivity of the display panel 1 to green can be increased to neutralize the purple, so that the final hue of the display panel 1 is improved.

[0105] In a possible implementation, Fig.12 As shown, the display panel 1 includes a substrate 11, a pixel defining layer 12, a light emitting layer 13 and a light regulating layer 14. The pixel defining layer 12 is located on one side of the substrate 11 and includes a plurality of pixel openings 121. The light emitting layer 13 is located on one side of the substrate 11 and includes a plurality of light emitting units, which are located in the pixel openings 121. The plurality of light emitting units include a first light emitting unit 131, a second light emitting unit 132 and a third light emitting unit 133. The light regulating layer 14 is located on the side of the light emitting layer 13 away from the substrate 11, and includes a light shielding portion 140 and a multicolor filter portion 146. The orthographic projection of the light shielding portion 140 on the substrate 11 is located in the orthographic projection of the pixel defining layer 12 on the substrate 11. The multicolor filter portion 146 corresponds to the light emitting unit, and the multicolor filter portion 146 allows the light emitted by the first light emitting unit 131, the second light emitting unit 132 and the third light emitting unit 133 to pass through. The pixel defining layer 12 is made of green material.

[0106] Specifically, the light regulating layer 14 includes a plurality of filter areas, including a first filter area 141, a second filter area 142, and a third filter area 143 corresponding to the first light emitting unit 131, the second light emitting unit 132, and the third light emitting unit 133, respectively. The multicolor filter portion 146 is disposed in each of the first filter area 141, the second filter area 142, and the third filter area 143. The light regulating layer 14 also includes a shading area 144 located between two adjacent filter areas, and the shading portion 140 is located in the shading area 144. The shading area 144 may also include the multicolor filter portion 146, and the multicolor filter portion 146 may be located on the side of the shading portion 140 facing away from the substrate 11. The material of the multicolor filter portion 146 may include organic glue and red dye, green dye, and blue dye, and the organic glue may include acrylic colloid.

[0107] Specifically, since the organic glue has strong fluidity, the multi-color filter portion 146 arranged in an entire layer can be prepared after the light shielding portion 140 is prepared, thereby improving the strength of the surface of the light regulating layer 14 facing away from the substrate 11 .

[0108] In a possible implementation, Fig.12 and Fig.13 As shown, the material of the light shielding portion 140 can be a black organic material or a green organic material.

[0109] Specifically, Fig.13 As shown, when the material of the light shielding portion 140 is a green organic material, the pixel defining layer 12 can be made of a black material, specifically a black organic material. At this time, the green light shielding portion 140 can increase the reflectivity of the display panel 1 to green to neutralize the purple, so that the final hue of the display panel 1 is improved.
