Abstract

A thin film transistor includes a gate electrode, a channel layer, a source electrode, and a drain electrode. The channel layer is made of an amorphous oxide semiconductor. The channel layer includes one high oxygen ion concentration region, or two high oxygen ion concentration regions one above the other. An oxygen ion density of each high oxygen ion concentration region is in a range of from about 1×10to about 1×10per cubic centimeter. A thin film transistor substrate and a method of manufacturing the thin film transistor substrate are also provided.
