METHOD FOR MANUFACTURING THIN FILM TRANSISTOR, THIN FILM TRANSISTOR MANUFACTURE BY THE METHOD, AND DISPLAY DEVICE INCLUDING THIN FILM TRANSISTOR

摘要

PROBLEM TO BE SOLVED: To simplify a patterning process while improving the level of pattern precision of an organic semiconductor layer. SOLUTION: The method for manufacturing a thin film transistor comprises a step for forming an organic insulating film on a substrate, forming a bank including first and second concave portions and a third concave portion formed on the first and second concave portions in the organic insulating film, forming a source electrode and a drain electrode in the first and second concave portions, and forming an active layer that comes into contact with the source electrode and the drain electrode in the third concave portion.
