Patent ID: 8907559

Claim:
A semiconductor device comprising: a display portion over a first substrate, the display portion comprising a first pixel and a second pixel, wherein each of the first pixel and the second pixel comprises: a transistor comprising a gate electrode, a gate insulating layer, a semiconductor layer, a source electrode, and a drain electrode; an interlayer insulating film over the transistor; a pixel electrode over the interlayer insulating film, the pixel electrode being electrically connected to one of the source electrode and the drain electrode; a first insulating layer over the interlayer insulating film, the first insulating layer covering an edge portion of the pixel electrode; an electroluminescent layer over the pixel electrode and the first insulating layer, the electroluminescent layer comprising a light-emitting layer; a cathode over the electroluminescent layer, wherein the electroluminescent layer in the first pixel includes iridium, and wherein the electroluminescent layer in the second pixel comprises a fluorescent material.
