Abstract:
A method of manufacturing an active-matrix substrate comprising:a first step of forming a semiconductor layer on an insulating substrate, said semiconductor layer having a specific shape; a second step of forming a gate insulating film on the semiconductor layer; a third step of forming a metal film on the gate insulating film; a fourth step of making openings in a first area and second area of the metal film, said first area overlapping the semiconductor layer and said second area not overlapping the semiconductor layer; a fifth step of injecting impurities into the semiconductor layer through the openings made in the first area of the metal film, thereby forming a source region and a drain region in the semiconductor layer; and a sixth step of removing some parts of the metal film, including the second area having the openings, thereby forming gate lines and auxiliary capacitance lines.
