Patent ID: 8008670

Claim:
A light emitting device comprising: a semiconductor layer of a transistor formed over a substrate; a first electrode electrically connected to the semiconductor layer of the transistor; a first insulating film formed over the first electrode; a light emitting layer formed over the first insulating film; a second insulating film formed over the light emitting layer; a second electrode formed over the second insulating film; and a first carrier supply layer and a second carrier supply layer interposed between the first and second insulating films, wherein the light emitting layer is directly in contact with upper and side surfaces of the first and second carrier supply layers, wherein the light emitting layer includes a base material and an additive material, wherein the first and second carrier supply layers comprise a semiconductor material including at least one of an n-type impurity element and a p-type impurity element, and wherein the semiconductor layer of the transistor includes a metal oxide.
