METHOD FOR MANUFACTURING THIN FILM LAYER PATTERN, DISPLAY SUBSTRATE, METHOD FOR MANUFACTURING DISPLAY SUBSTRATE, AND DISPLAY DEVICE

摘要

A method for manufacturing a thin film layer pattern, a display substrate, a method for manufacturing the display substrate, and a display device. The method for manufacturing the thin film layer pattern comprises: forming on a substrate (10) a first thin film layer (11) to be patterned; forming a first covering layer (20) on the surface of the first thin film layer (11); forming a first covering layer pattern (201) by means of beam melting; and then removing the first thin film layer (11) not covered by the first covering layer pattern (201), so as to form a first thin film layer pattern (101). The method can, by means of the beam melting technique, enhance precision and resolution of the display substrate, improve product quality and reduce production cost.
