Production method of orientation layer and production method of display substrate

Abstract

The invention discloses a production method of an orientation layer and a production method of a display substrate, and relates to the technical field of display. The production method of the orientation layer is used for forming the orientation layer on the integral display substrate so as to enable all liquid crystal molecules in a liquid crystal display device to be normally oriented. The production method of the orientation layer comprises: providing the display substrate on which a patterned structure is formed; covering wetting fluid on the integral display substrate, wherein the wetting fluid can be fused with orientation liquid; by a transfer roller, transferring the orientation liquid to the display substrate covered with the wetting fluid; curing the orientation liquid to form the orientation layer. The production method of the orientation layer, which is disclosed by the invention, is used for producing the orientation layer on the display substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing an alignment layer and a method for manufacturing a display substrate. Background technique [0002] Liquid crystal display devices have the advantages of low power consumption, low radiation, and thin bodies, and their applications are becoming more and more extensive. Wherein, the liquid crystal display device includes a display substrate, and an alignment layer is arranged on the display substrate, and the alignment layer is used to make the liquid crystal molecules in the liquid crystal display device have an initial alignment. [0003] In the prior art, the manufacturing process of the alignment layer includes: the first step, cleaning the display substrate; the second step, transferring the alignment liquid to the display substrate through the transfer roller; the third step, solidifying the alignment liquid on the display substrate, An alignmen...

AI Technical Summary

Problems solved by technology

[0004] However, the inventors of the present application found that the manufacturing process of the above-mentioned alignment layer has the following problems: due to the patterned structure on the display substrate, the transfer roller cannot contact the areas on both sides of the patterned structure on the display substrate, resulting in transfer The roller cannot transfer the alignment liquid to this area, so that the alignment layer cannot be formed in this area, and the liquid crystal molecules corresponding to this area cannot be aligned normally, and the display effect of the liquid crystal display device is not good.
