Claim Text:
1. A display device comprising: a first wiring; a second wiring; a first transistor comprising a first gate electrode, a gate insulating film over the first gate electrode, and a first semiconductor layer comprising a first LDD region over the gate insulating film; a second transistor comprising a second gate electrode, the gate insulating film over the second gate electrode, and a second semiconductor layer comprising a second LDD region over the gate insulating film; 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 a part of the first LDD region overlaps with the first gate electrode, wherein a part of the second LDD region overlaps with the second gate electrode, wherein the first gate electrode is electrically connected to the first wiring, wherein one of a source electrode and a drain electrode of the second transistor is electrically connected to the second wiring, wherein the first gate electrode 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 the second gate electrode, and wherein the first wiring is parallel to the second wiring.
