Semiconductor device and display device

Abstract

A semiconductor device includes: a first insulating film at least including silicon and nitrogen; a second insulating film disposed on an upper-layer side of the first insulating film and at least including silicon and oxygen; a semiconductor portion formed of part of a semiconductor film disposed on the upper-layer side of the second insulating film; a third insulating film disposed on the upper-layer side of the semiconductor film; and a first electrode formed of part of a first transparent electrode film disposed on the upper-layer side relative to the third insulating film, and disposed in such a manner as to at least partially overlap with part of the semiconductor portion in which a first contact hole that connects the semiconductor portion and the first electrode is provided at a position overlapping at least both the semiconductor portion and the first electrode in the third insulating film, and an opening is provided at a position overlapping at least part of the first contact hole in the second insulating film.
