Abstract
Provided is a display device including a thin-film transistor and a capacitor element, the thin-film transistor includes: a first insulating film (IN) which is formed to cover an area where a gate electrode (GT) is formed; a second insulating film (IN) which is formed on the first insulating film, the second insulating film having an opening (OP) formed in the area in plan view; a semiconductor layer (SCLt) which is formed on the second insulating film to cross the opening, the semiconductor layer including high concentration areas (CN); a third insulating film (IN) which is formed on the semiconductor layer to expose apart of each of the high concentration areas; and a pair of electrodes (DT, ST) each having electrical connection to the part; and the capacitor element includes a dielectric film which is formed of the same layer and the same material as the third insulating film.
