Patent ID: 8174016

Claim:
A semiconductor device comprising: a substrate; transistors each having a source electrode and a drain electrode provided on a surface of the substrate to be separated from each other, a semiconductor layer provided at least between the source electrode and the drain electrode, a gate insulator layer provided so as to cover a surface of the semiconductor layer opposite to the substrate, and a gate electrode provided on a surface of the gate insulator layer opposite to the semiconductor layer; an insulator layer provided on a surface of the gate insulator layer opposite to the semiconductor layer; and pixel electrodes each provided on a surface of the insulator layer opposite to the gate insulator layer and electrically connected to the corresponding source electrode or the corresponding drain electrode, wherein the insulator layer has through portions, each of which passes therethrough in the thickness direction with an increasing width from the corresponding pixel electrode side toward the gate insulator layer side, and the gate electrode is provided on the gate insulator layer around the bottom of the corresponding through portion.
