Patent ID: 8039853

Claim:
A light-emitting device comprising: a switching thin film transistor and a driving thin film transistor, each including an active layer and a gate electrode with a gate insulating film interposed therebetween; a source line and a connection wiring electrically connected to the active layer of the switching thin film transistor; a power supply line electrically connected to the active layer of the driving thin film transistor; an interlayer insulating film formed over the switching thin film transistor and the driving thin film transistor; a pixel electrode formed over and in contact with the interlayer insulating film, wherein the pixel electrode is electrically connected to the active layer of the driving thin film transistor; a light emitting layer formed over the pixel electrode; a counter electrode formed over the light emitting layer; and a conductive film formed over and in contact with the interlayer insulating film, wherein the conductive film overlaps the gate electrode of the switching thin film transistor.
