Patent ID: 8717269

Claim:
A semiconductor device comprising: a first pixel over a substrate, wherein the first pixel comprises: a gate electrode over the substrate; a first insulating layer over the gate electrode; a semiconductor layer over the first insulating layer; a second insulating layer over the semiconductor layer; a source electrode over the second insulating layer, the source electrode electrically connected to the semiconductor layer; a drain electrode over the second insulating layer, the drain electrode electrically connected to the semiconductor layer; a first electrode electrically connected to one of the source electrode and the drain electrode; a third insulating layer over the first electrode; an electroluminescent layer over the first electrode and the third insulating layer; a second electrode over the electroluminescent layer and the third insulating layer; and a color filter arranged so that light emitted from the electroluminescent layer enters; a second pixel over the substrate; a third pixel over the substrate; a fourth pixel over the substrate; a first line electrically connected to the first pixel and the second pixel, wherein the first line is electrically connected to the other one of the source electrode and the drain electrode; a second line electrically connected to the first line; and a third line electrically connected to the third pixel and the fourth pixel and electrically connected to the second line, wherein the second line intersects with the first line and the third line.
