Patent ID: 7781964

Claim:
An organic electroluminescent device comprising: a substrate, at least a first surface of the substrate having conductivity; a common electrode; a first insulating film interposed between the substrate and the common electrode, the first insulating film including a portion of a first opening, a portion of a second opening; a semiconductor film interposed between the first insulating film and the common electrode, the semiconductor film receiving a current from the first surface of the substrate via the portion of a first opening; a second insulating film interposed between the semiconductor film and the common electrode, at least a part of the second insulating film being in contact with the first surface of the substrate via the portion of a second opening; a capacitance electrode interposed between the second insulating film and the common electrode, the capacitance electrode sandwiching the part of the second insulating film with the first surface of the substrate via the portion of a second opening; a gate electrode interposed between the second insulating film and the common electrode, the gate electrode overlapping the semiconductor film; an intermediate insulating film interposed between the capacitance electrode and the common electrode, the intermediate insulating film interposed between the gate electrode and the common electrode; a pixel electrode interposed between the intermediate insulating film and the common electrode, the pixel electrode receiving a current via the semiconductor film; a light-emitting layer interposed between the pixel electrode and the common electrode; and a power supply section supplying a current to the first surface of the substrate, the first insulating film interposed between the substrate and the power supply section.
