Claim Text:
1. A semiconductor device comprising: a semiconductor layer over an insulating surface; a conductive layer electrically connected to the semiconductor layer; a first insulating layer over the conductive layer; a pixel electrode on the first insulating layer, the pixel electrode electrically connected to the conductive layer through a contact hole in the first insulating layer; a second insulating layer over the first insulating layer, the second insulating layer overlapping an end portion of the pixel electrode; an EL layer over the pixel electrode; a second electrode over the EL layer; an auxiliary wiring between the first insulating layer and the second electrode; and a light-shielding layer over the second electrode, wherein the auxiliary wiring is in contact with the second insulating layer, wherein the EL layer does not overlap the pixel electrode in a region, wherein the auxiliary wiring is in contact with the second electrode in the region, and wherein the light-shielding layer overlaps the auxiliary wiring.
