A semiconductor having an active layer; a gate insulating film in contact with the semiconductor; a gate electrode opposite to the active layer through the gate insulating film; a first nitride insulating film formed over the active layer; a photosensitive organic resin film formed on the first nitride insulating film; a second nitride insulating film formed on the photosensitive organic resin film; and a wiring provided on the second, nitride insulating film. A first opening portion is provided in the photosensitive organic resin film, an inner wall surface of the first opening portion is covered with the second nitride insulating film, a second opening portion is provided in a laminate including the gate insulating film, the first nitride insulating film, and the second nitride insulating film inside the first opening portion, and the semiconductor is connected with the wiring through the first opening portion and the second opening portion.
