    Abstract: Provided is a thin film transistor capable of improving reliability in the thin film transistor including an oxide semiconductor layer. A thin film transistor including: a gate electrode; a gate insulating film formed on the gate electrode; an oxide semiconductor layer forming a channel region corresponding to the gate electrode on the gate insulating film; a channel protective film formed at least in a region corresponding to the channel region on the oxide semiconductor layer; and a source/drain electrode. A top face and a side face of the oxide semiconductor layer are covered with the source/drain electrode and the channel protective layer on the gate insulating film.
