Abstract:
1. A method of manufacturing an electro-optical apparatus including a first thin-film transistor having a first gate electrode, a first gate insulating layer and a first active layer in a pixel region of a device substrate and a second thin-film transistor having a second gate electrode, a second gate insulating layer and a second active layer in a region other than the pixel region of the device substrate, the method comprising: simultaneously forming the first gate electrode and the second gate electrode; forming the first gate insulating layer and the second gate insulating layer; forming the first active layer and the second active layer; and thinning an insulating film which overlaps the second gate electrode at an upper layer side by etching to reduce the thickness of the second gate insulating layer to be smaller than that of the first gate insulating layer.
