Patent ID: 8476665

Claim:
A display device comprising: a substrate; a first wiring over the substrate; a second wiring over the substrate; a first transistor over the substrate, a gate electrode of the first transistor being electrically connected to the first wiring; a second transistor over the substrate, one of a source electrode and a drain electrode of the second transistor being electrically connected to the second wiring; an insulating film over the first transistor and the second transistor; a first electrode over the insulating film; a light emitting layer over the first electrode; and a second electrode over the light emitting layer, wherein the gate electrode of the first transistor is formed in a different layer from the first wiring, wherein one of a source electrode and a drain electrode of the first transistor is electrically connected to a gate electrode of the second transistor, and wherein the first wiring is parallel to the second wiring.
