Substrate, manufacturing method and display panel

Abstract

The invention discloses a substrate, a manufacturing method and a display panel. The substrate comprises a substrate body and a black matrix formed on the substrate body; the black matrix at least comprises a first shading layer and a second shading layer; the first shading layer is located on one side of the substrate body; the second shading layer is located on one side, far away from the substrate body, of the first shading layer; the refraction index of the first shading layer is smaller than that of the second shading layer and is larger than that of the substrate body; the side, close tothe first shading layer, of the second shading layer is provided with a microstructure; the microstructure is a bulge facing the substrate body; and the raw materials of the black matrix at least include carbon black, bisphenol fluorene epoxy acrylate, propylene glycol methyl ether acetate, ethyl lactate and bis(2-methoxyethyl)ether, diethylene glycol methyl ethyl ether and an additive, wherein the additive at least comprises an organic silicon compound, a fluorine-substituted organic matter, acrylic resin and polyethylene resin. The reflectivity of the substrate can be remarkably reduced onthe premise that the display quality of a product is not influenced.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a substrate, a manufacturing method and a display panel. Background technique [0002] Liquid crystal display devices have the advantages of thinness, low power consumption and low radiation, and are widely used in various fields. However, the display device in the prior art has the problem of high reflectivity, and reflections will be formed on the light-emitting side of the display device, and the content displayed by the display device cannot be seen clearly under strong light. Therefore, it is usually required to reduce the reflectivity of the display device while maintaining the transmittance of the display device, so as to improve the display quality. [0003] In the existing technical solutions for reducing reflectivity, two layers of 1 / 4 wave plates are usually added to the structure of the display panel, such as adding a layer of 1 / 4 to the film layer ...

AI Technical Summary

Problems solved by technology

[0003] In the existing technical solutions for reducing reflectivity, two layers of 1 / 4 wave plates are usually added to the structure of the display panel, such as adding a layer of 1 / 4 to the film layer of the polarizer and the film layer of the color filter substrate. Although the wave plate can reduce the reflectivity, due to the addition of a 1 / 4 wave plate, the transmittance decreases, which affects the display quality
