Embodiment 1

[0026] figure 1 A schematic diagram showing the structure of the display substrate in this embodiment, figure 2 express figure 1 Section along A-A Figure 1 , image 3 express figure 1 Section along B-B Figure 1 , Figure 4 express figure 1 Section along A-A Figure II , Figure 5 express figure 1 Section along B-B Figure II .

[0027] combine Figure 1-Figure 5 As shown, a display substrate is provided in this embodiment, and the display substrate includes a black matrix 1, and the surface of the black matrix 1 close to the display side is uneven, so as to reduce the light reflected by the black matrix 1 to the display side and reduce the brightness of the display panel. Reflectivity reduces the impact on the contrast of the display screen and improves the quality of the display screen.

[0028] The display substrate may be a color filter substrate or a COA array substrate.

[0029] The technical solution of the present invention is especially suitable for th...

Embodiment 2

[0046] This embodiment provides a display device, including the display substrate in Embodiment 1. Since the reflectivity of the black matrix is ​​reduced, the specular reflection effect of the black matrix is ​​reduced, and the quality of the display image is improved.

[0047] The display device may specifically be any product or component with a display function such as a display panel, electronic paper, a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, and the like.

Embodiment 3

[0049] Based on the same inventive idea as the technical solution in Embodiment 1, this embodiment provides a method for manufacturing a display substrate, the method includes a step of forming a black matrix, and the step of forming a black matrix includes:

[0050] An uneven structure is formed on the surface of the black matrix near the display side.

[0051] The black matrix prepared by the above manufacturing method has an uneven surface, which effectively reduces the light reflected to the display side, ensures the contrast of the display substrate, and improves the quality of the display screen.

[0052] Wherein, the step of forming the black matrix includes the step of forming a first sublayer, the surface of the first sublayer is uneven, and is used to provide the black matrix with an uneven surface.

[0053] The first sub-layer can be made of metallic material or insulating material.

[0054] Further, the step of forming the black matrix also includes:

[0055] For...

Abstract

The invention relates to the technical field of display, and discloses a display substrate and a manufacturing method thereof and a display device. The manufacturing method comprises: forming an uneven structure at the surface of a black matrix, and enabling the surface, close to a display side, of the black matrix to be uneven, so that when the method is applied to the display device, light reflected to the display side from the black matrix is reduced, a reflection ratio of a display panel is reduced, influence on a contrast of a display picture is reduced and quality of the display picture is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] The main body of the existing liquid crystal display device (Liquid Crystal Display Device, referred to as "LCD") is a display panel, and the display panel is formed by pasting the array substrate and the color filter substrate through a box-forming process. There will be a certain deviation between the color filter substrates, which will lead to problems such as a decrease in the aperture ratio of the LCD display device and light leakage. Moreover, the higher the PPI of the LCD device, the more serious the reduction in the aperture ratio. At the same time, the brightness and color gamut of the product will decrease, and the energy consumption will increase. [0003] In order to eliminate the deviation between the array substrate and the color filter substrate, increase the ...
