Abstract
It is an object to provide a technique capable of suppressing a damage on a semiconductor channel layer due to a process of forming a source electrode and a drain electrode and also suppressing a short channel effect. A thin film transistor includes a gate electrode, a first insulating film, a source electrode, a drain electrode, a second insulating film, and a semiconductor channel layer that includes an oxide semiconductor. The second insulating film is disposed on the first insulating film, the source electrode, and the drain electrode. The semiconductor channel layer is electrically connected to the source electrode and the drain electrode via a first contact hole and a second contact hole provided in the second insulating film.
