Patent ID: 8643801

Claim:
A display device, comprising: a substrate; a display element provided on said substrate; a thin film transistor provided on said substrate, and having a first semiconductor oxide film including a source region and a drain region on both sides of a channel region, said first semiconductor oxide film having first low resistance areas each of whose oxygen concentration is lower than that of said channel region in at least parts of said source region and said drain region in a depth direction from upper surfaces of said source region and said drain region; a second semiconductor oxide film provided in an area, of said substrate, other than the area in which said thin film transistor is provided, and having a second low resistance area whose oxygen concentration is lower than that of said channel region in at least a part in the depth direction from the upper surface; and a high resistance film covering said thin film transistor, said second semiconductor oxide film, and said substrate, made of a metallic oxide, having a first translucent area in an area contacting said first low resistance area, and having a second translucent area in an area contacting said second low resistance area.
