Substrate surface treatment method, substrate and liquid crystal display panel

Abstract

Disclosed by the present application are a substrate surface treatment method, a substrate, and a liquid crystal display panel, the method comprising: providing a substrate; providing a first solution of a compound containing a phosphate group, the first functional group of the compound containing the phosphate group being a rigid molecular group containing at least one from among a hydroxyl group, an amine group and a carboxyl group; immersing the substrate in the first solution to perform surface treatment on the substrate such that the surface of the substrate forms a molecular film layer containing the first functional group. By means of the method, the present application may improve the alignment uniformity of self-orienting liquid crystals and the surface of the substrate, and enhance liquid crystal alignment.

Description

technical field [0001] The invention relates to the technical field of display manufacturing, in particular to a substrate surface treatment method, a substrate and a liquid crystal display panel. Background technique [0002] In existing liquid crystal displays, self-orienting liquid crystals usually use small molecule material additives such as hydroxysilane to form hydrogen bonds with the substrate surface to achieve alignment of liquid crystals. However, the substrate surface after etching and high temperature treatment in the actual production process has a different surface Roughness, uneven dispersion of hydroxyl groups on the surface, etc., lead to weak alignment between the self-aligned liquid crystal and the surface of the substrate, and poor alignment of the liquid crystal. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a substrate surface treatment method, a substrate and a liquid crystal display pa...
