Manufacturing method of display substrate, display substrate and display device

Abstract

The invention provides a manufacturing method of a display substrate, the display substrate and a display device. The method comprises the step of forming a black matrix; when forming the black matrix, a metal graph for manufacturing the black matrix is formed, wherein the metal graph is prepared from metalloid or metalloid alloy; the metal graph is treated through an alkaline solution so as to form the black matrix with rough surface. According to the method, the metal black matrix with the rough surface can be formed, so that the reflecting rate of a metal material can be reduced; in addition, the reflecting rate of the display panel to the outside light can be reduced; the display contrast ratio is increased, and the image quality is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a manufacturing method of a display substrate, a display substrate and a display device. Background technique [0002] Display devices such as liquid crystal display devices LCD and organic electroluminescent devices OLED have become a necessity in people's lives and are quietly changing people's lives. People's requirements for the resolution, color gamut, and brightness of display devices are also increasing. High, recently companies have developed products with a pixel density (PPI) of 500 or even 600PPI. [0003] In the prior art LCD display devices, the array substrate and the filter substrate are pasted together through a box-forming process. There will be a certain deviation between the patterns corresponding to the array substrate and the filter substrate when the box is formed, and the deviation will be This leads to problems such as a decrease in the aperture rati...

Problems solved by technology

[0003] In the prior art LCD display devices, the array substrate and the filter substrate are pasted together through a box-forming process, and there will be a certain deviation between the patterns corresponding to the array substrate and the filter substrate when the box is formed, and the deviation will be Causes problems such as lower aperture ratio and light leakage of LCD display devices

In addition, the higher the PPI of the LCD device, the more serious the decrease in the aperture ratio. At the same time, the brightness and color gamut of the product will decrease, and the energy consumption will increase.
