Abstract:
A thin-film transistor having a protective insulation film covering said thin-film transistor and a pixel electrode provided on said protective insulation film in electrical connection with said thin-film transistor, comprising:a gate electrode provided on a substrate; a gate insulation film provided on said substrate so as to cover said gate electrode; a semiconductor layer provided on said gate insulation film so as to cover said gate electrode when viewed in a direction perpendicular to a principal surface of said substrate; a first ohmic electrode provided on said semiconductor layer so as to be located at a first side of said gate electrode when viewed in a direction perpendicular to said principal surface; a second ohmic electrode provided on said semiconductor layer so as to be located at a second, opposite side of said gate electrode when viewed in a direction perpendicular to said principal surface; said gate insulation film comprising: an insulation pattern formed on said gate electrode; and a pair of insulation films disposed on said substrate at both sides of a gate structure including said gate electrode and said insulation pattern, such that said pair of insulation films have respective surfaces continuing to a surface of said insulation pattern.
