Abstract

The invention relates to the technical field of display, and provides an alignment film manufacturing method which comprises the steps: providing a substrate which comprises at least one display area; forming a photolysis layer capable of photolysis at the edge of the display area; coating the substrate with an alignment film, and forming a cutting line on the alignment film along the intersection of the photolysis layer and the display area, wherein the alignment film at least covers the display area and the photolysis layer, ; illuminating the photolysis layer to remove the photolysis layer; and cutting the alignment film along the cutting line to form a flat alignment film boundary. According to the alignment film manufacturing method provided by the invention, the reliability and the qualified rate of products can be improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method for manufacturing an alignment film. Background technique [0002] With the development of photoelectric display technology and semiconductor manufacturing technology, liquid crystal displays (Liquid Crystal Display, LCD) have become the mainstream of display devices. A liquid crystal display usually includes a thin film transistor (Thin Film Transistor, TFT) array substrate and a color filter (Color Filter, CF) substrate, and a liquid crystal layer (Liquid Crystal, LC) arranged between the TFT array substrate and the CF substrate, in order to make the LC have A certain orientation usually needs to coat a layer of alignment film (Polyimide, PI) on the CF substrate and TFT array substrate; however, the alignment film usually has a certain degree of fluidity, and it is easy to diffuse unevenly around the display area, resulting in product reliability. Sex is lo...
