Abstract:
1. A semiconductor device comprising: a substrate having a metal surface; a base insulating film formed on the substrate having the metal surface; a switching thin film transistor and a current controlling thin film transistor, both formed on the base insulating film in a pixel unit, wherein each of the thin film transistors comprises a semiconductor layer and a gate electrode with a gate insulating film interposed therebetween; an interlayer insulating film formed over the switching thin film transistor and the current controlling thin film transistor, wherein a portion of the interlayer insulating film is removed so as to expose a portion of the base insulating film; a metal wiring formed on the exposed portion of the base insulating film; and a storage capacitor comprising a portion of the substrate having the metal surface, the exposed portion of the base insulating film, and the metal wiring.
