Patent ID: 8309963

Claim:
An organic luminescence transistor device comprising a substrate, an assistance electrode layer provided on a side of an upper surface of the substrate, an insulation film provided on a side of an upper surface of the assistance electrode layer, a first electrode provided locally on a side of an upper surface of the insulation film, the first electrode covering an area of a predetermined size, an electric-charge-injection inhibiting layer provided on an upper surface of the first electrode, the electric-charge-injection inhibiting layer having a shape larger than that of the first electrode in a plan view, the electric-charge-injection inhibiting layer being made of a material that inhibits both holes and electrons from being transported therethrough, an electric-charge injection layer provided on the side of an upper surface of the insulation film at an area not provided with the first electrode or the electric-charge-injection inhibiting layer, a luminescent layer provided on an upper surface of the electric-charge-injection inhibiting layer and on an upper surface of the electric-charge injection layer, and a second electrode layer provided on a side of an upper surface of the luminescent layer.
