Abstract

A method for forming a thin-film layer pattern, a display substrate and a manufacturing method thereof, and a display device are provided. The method for forming the thin-film layer pattern comprises: forming a first thin-film layer to be patterned on a substrate; forming a first overcoat (OC) layer on a surface of the first thin-film layer; forming a first overcoat layer pattern by beam melting; and removing the first thin-film layer not covered by the first overcoat layer pattern to form a first thin-film layer pattern. The method adopts beam melting process and hence can improve the accuracy and the resolution of the display substrate, improve the product quality and reduce the manufacturing cost.
