Abstract:
A TFT in which a channel region is formed of an oxide semiconductor is provided. Threshold voltage shift due to holes photoexcited in the vicinity of a source electrode and a drain electrode is prevented so that reliability is enhanced. A lower semiconductor layer is partially provided between an oxide semiconductor layer and a gate insulating film. The lower semiconductor layer is present in at least one of a source overlapping region where the oxide semiconductor layer overlaps a source electrode and a drain overlapping region where the oxide semiconductor layer overlaps a drain electrode. In contrast, a region where the lower semiconductor layer is absent is provided between the source overlapping region and the drain overlapping region.

Claim (Index 1):
A thin film transistor comprising:\n a gate electrode; a gate insulating film that covers the gate electrode; an oxide semiconductor layer provided above the gate insulating film and opposed to the gate electrode with intermediation of the gate insulating film; a lower semiconductor layer partially provided between the oxide semiconductor layer and the gate insulating film so as to be opposed to the gate electrode; and a source electrode and a drain electrode that are provided above the oxide semiconductor layer and are brought into contact with the oxide semiconductor layer, wherein the lower semiconductor layer is present in at least one of a source overlapping region where the oxide semiconductor layer overlaps the source electrode and a drain overlapping region where the oxide semiconductor layer overlaps the drain electrode, and a region where the lower semiconductor layer is absent is provided between the source overlapping region and the drain overlapping region.
