a light shielding layer 5 located on the side of the color resist layer 3 and the dielectric layer 4 away from the first substrate 1, wherein the light shielding layer 5 has a light shielding portion 501 and a plurality of hollow portions 502;
in a first direction X, the dielectric layer 4 and the color resist layer 3 have at least one refractive interface, and the refractive interface at least partially overlaps with the light shielding portion 501 of the light shielding layer 5, and is configured to guide at least part of the light emitted directly below the light shielding portion 501 to the hollow portion 502 for emission, where the first direction X is perpendicular to the plane of the display panel.
It should be noted that, in this embodiment of the application, the light-shielding portion of the light-shielding layer corresponds to the non-opening area of the display panel, the hollow portion of the light-shielding layer corresponds to the opening area of the display panel, when the display panel displays a screen, the opening area of the display panel is used for transmitting light, and no light is emitted from the non-opening area of the display panel.
Therefore, in the display panel provided in the embodiment of the present application, the display panel includes a color resistance layer and a dielectric layer between the first substrate and the second substrate, and in a direction perpendicular to a plane of the display panel, the dielectric layer and the color resistance layer have at least one refraction interface, the refraction interface at least partially overlaps with the light-shielding portion of the light-shielding layer, and is used for guiding at least part of the light emitted to a position right below the light-shielding portion to the hollow-out portion to be emitted, so that the display panel can guide at least part of the light emitted to the light-shielding portion of the light-shielding layer to the hollow-out portion of the light-shielding layer to be emitted, that is, at least part of the light emitted to the non-opening area of the display panel to be emitted to the opening area of the display panel, so as to increase the amount of the light emitted from the opening area of the display panel and improve the display brightness of the opening area of the display panel, and finally, the display brightness of the display panel is improved.
Optionally, on the basis of the foregoing embodiment, in an embodiment of the present application, the display panel is a liquid crystal display panel, and in this embodiment, as shown in fig. 2, the display panel further includes: a liquid crystal layer 6 between the first substrate 1 and the second substrate 2.
On the basis of the above embodiment, in an embodiment of the present application, as shown in fig. 1, the display panel further includes: a plurality of support columns 7 between the first substrate 1 and the second substrate 2 for supporting a distance between the first substrate 1 and the second substrate 2 so that the liquid crystal layer 6 can be accommodated between the first substrate 1 and the second substrate 2.
It should be noted that, with the development of display technology, more and more curved display panels are applied to daily work and life of people to improve the display quality of large-sized display panels. However, in practical application, the large-size curved-surface display screen has a light leakage phenomenon and a color crosstalk phenomenon, which affect user experience, and particularly, the light leakage phenomenon and the color crosstalk phenomenon are more significant for the large-size curved-surface liquid crystal display panel.
The liquid crystal display device comprises a first substrate, a second substrate and a liquid crystal layer, wherein the first substrate is provided with a plurality of display pixels on one side facing the liquid crystal layer, gaps are formed between opening areas corresponding to adjacent display pixels, the second substrate is provided with a colored resistance layer and a light shielding layer on one side facing the liquid crystal layer, the colored resistance layer is provided with a plurality of color resistance units and corresponds to the display pixels one by one, the light shielding layer is provided with a light shielding part and a plurality of hollow parts, the hollow parts correspond to the color resistance units one by one, and the light shielding part is used for shielding the gaps between the opening areas corresponding to the adjacent display pixels.
When the curved liquid crystal display panel is manufactured, a flat liquid crystal display panel is usually manufactured first, and then the flat liquid crystal display panel is bent to obtain the curved liquid crystal display panel. In the process of bending a flat liquid crystal display panel to obtain a curved liquid crystal display panel, the relative positions of each display pixel and each color resistor unit are dislocated due to bending.
The display panel comprises an A display pixel, a B display pixel and a C display pixel, the color resistance layer comprises an A color resistance unit, a B color resistance unit and a C color resistance unit, wherein the A display pixel corresponds to the A color resistance unit, the B display pixel corresponds to the B color resistance unit, the C display pixel corresponds to the C color resistance unit, for example, in the process of bending the planar liquid crystal display panel to obtain the curved liquid crystal display panel, the relative positions of the display pixels and the color resistance units can be staggered due to bending, so that part of light transmitted by the A display pixel region, which should be transmitted to the A color resistance unit, is transmitted to the B color resistance unit, color crosstalk is generated, the quality of a display picture is influenced, and further the user experience is influenced.
In addition, in the process of bending the planar liquid crystal display panel to obtain the curved liquid crystal display panel, the relative positions between each display pixel and each light shielding part are also dislocated due to bending, so that light emitted to the light shielding parts from the outside is emitted to the metal wires on the first substrate corresponding to the light shielding parts through the hollow parts and is reflected by the metal wires to be emitted from the display surface of the display panel, and therefore light is transmitted in an area which should be in a dark state, a light leakage phenomenon is generated, and the contrast of the curved liquid crystal display panel is affected.
Therefore, in an optional embodiment of the present application, as shown in fig. 2, the color resistance layer 3, the dielectric layer 4, and the light shielding layer 5 are located at one side of the liquid crystal layer 6 facing the first substrate 1, so as to reduce a distance between the color resistance layer 3, the light shielding layer 5, and the first substrate 1, thereby reducing a misalignment degree between the color resistance unit and the corresponding display pixel and a misalignment degree between the hollow portion and the corresponding display pixel in a process of bending the flat liquid crystal display panel to obtain a curved liquid crystal display panel, alleviating a color crosstalk phenomenon and a light leakage phenomenon of the curved liquid crystal display panel, and improving user experience.
