Abstract: In a method for manufacturing an active matrix substrate, forming of an underlayer inorganic insulating film includes applying a resist onto the underlayer inorganic insulating film, performing an ashing process of forming a surface having irregularities on a surface of the resist by a first ashing process, and, after the ashing process has been performed, roughening a surface of the underlayer inorganic insulating film by performing a second ashing process and an etching process on the underlayer inorganic insulating film. When forming a semiconductor film, a surface of at least a part of the semiconductor film is roughened following a rough surface of the underlayer inorganic insulating film.
