Abstract:
A thin film transistor comprising:a first insulating film having a first and a second surface; an active layer positioned on a portion of said first surface of said first insulating film; a second insulating film positioned on said active layer and on said first surface of said first insulating film; a first gate electrode having a first area positioned on said second surface of said first insulating film; a second gate electrode positioned an said second insulating film, said second gate electrode having a second area less than or greater than said first area of said first gate electrode; and a first conductor connected to said first gate electrode for selectively applying a first voltage to said first gate electrode and operate said transistor in conjunction with or independent of said second gate electrode; and a second conductor connected to said second gate electrode for selectively applying a second voltage to said second gate electrode and operate said transistor in conjunction with or independent of said first gate electrode.
