Abstract:
A display device in which a thin film transistor is disposed on an insulative substrate, said thin film transistor comprising:a first gate electrode; a gate insulating film; a semiconductor film which is formed on said gate insulating film and which has a channel; a insulating film; a display electrode connected to a source which is formed in said semiconductor film, said display electrode being elongated so as to extend above said channel of said thin film transistor, wherein a second gate electrode formed between said first gate electrode and said display electrode; a light emitting layer formed on said display electrode, wherein said display electrode is an electrode used in an organic electro luminescent device; and at least one pixel, wherein each pixel comprises the thin transistor and a second thin film transistor, wherein the display electrode is extended above the thin film transistor but not extended above said second thin film transistor.
