Abstract

This application relates to the field of display technology, and provides a method for manufacturing an alignment film, including: providing a substrate, the substrate including at least one display area; forming a photodecomposable photolytic layer at the edge of the display area; coating an alignment film on the substrate , the alignment film covers at least the display area and the photolytic layer, and forms a cutting line on the alignment film along the intersection of the photolytic layer and the display area; illuminates the photolytic layer to remove the photolytic layer; cuts the alignment film along the cutting line to form Flat alignment film border. According to the manufacturing method of the alignment film provided in the present application, the reliability and yield of the product can be improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a method for fabricating an alignment film. Background technique [0002] With the development of optoelectronic display technology and semiconductor manufacturing technology, a liquid crystal display (Liquid Crystal Display, LCD) has now become the mainstream of display devices. A liquid crystal display usually includes a thin film transistor (Thin FilmTransistor, TFT) array substrate and a color filter (Color Filter, CF) substrate, and a liquid crystal layer (Liquid Crystal, LC) disposed between the TFT array substrate and the CF substrate. With a certain orientation, it is usually necessary 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 fluidity, and it is easy to spread unevenly around the display area, resulting in product reliability. low sex. [0003] In the ...
