ORGANIC THIN FILM TRANSISTOR ARRAY SUBSTRATE, METHOD FOR MANUFACTURING SAME, AND DISPLAY DEVICE

摘要

There are provided an organic thin film transistor array substrate and a method for manufacturing the same which increases the manufacturing efficiency of the organic thin film transistor array substrate. In the method, a pattern layer (3) of pixel electrode, and a pattern layer (2a) of source electrode and data line and a pattern layer (2b) of drain electrode, which are located above the pattern layer (3) of pixel electrode, are formed on a substrate through one patterning process; an organic semiconductor layer (4) that covers the pattern layer (2a) of source electrode and data line and the pattern layer (2b) of drain electrode and a gate insulating layer (5) that covers the organic semiconductor layer (4) are formed through one patterning process; and a pattern layer (7) of gate electrode and gate line is formed through one patterning process on the substrate formed with the gate insulating layer (5).
