Problems solved by technology

[0004] However, the coating process (such as inkjet printing) of this alignment substrate (polyimide) is prone to defects such as pin holes or uneven coating (mura)
Furthermore, the polyimide after coating needs to be cured, and the polyimide is easy to absorb moisture
Therefore, the quality of the existing alignment substrate is not easy to control, thus affecting the process yield of the display panel

Abstract

The invention provides a manufacturing method of a display panel and a display device. The method comprises the following steps of: sputtering alignment layers on a substrate; forming a liquid crystal layer between the alignment layers to form a liquid crystal box; applying a voltage to the liquid crystal box; irradiating ultraviolet light on the liquid crystal box; and arranging the display panel on a backlight module. The quality of an alignment film of the display panel can be improved with the method.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for manufacturing a display panel and a display device. 【Background technique】 [0002] Liquid Crystal Displays (LCDs) have been widely used in various electronic products. Most of the LCDs are backlight LCDs, which are composed of a liquid crystal display panel and a backlight module. A liquid crystal display panel is composed of two transparent substrates and a liquid crystal sealed between the substrates. In particular, a liquid crystal display panel with multi-domain alignment manufactured by a polymer-stabilized alignment (PSA) process can have a wide viewing angle, a high aperture ratio, and a high contrast And the advantages of simple manufacturing process. [0003] In the PSA process, the liquid crystal between the two transparent substrates can be doped with reactive monomer (reactive monomer), which is mixed with the liquid crystal molecules,...
