Abstract
A thin film transistor substrate includes: a substrate; and a first thin film transistor and a second thin film transistor that are disposed on the substrate. The first thin film transistor includes a first gate electrode and a first oxide semiconductor layer that is used as a channel. The second thin film transistor includes a second gate electrode and a second oxide semiconductor layer that is used as a channel. The first oxide semiconductor layer includes a first oxide semiconductor material that is different in mobility from a second oxide semiconductor material that the second oxide semiconductor layer includes.
