Patent ID: 8803140

Claim:
A light emitting device comprising: a transistor over a substrate, the transistor comprising: a first electrode; a first insulating film over the first electrode; a semiconductor film overlapping with the first electrode with the first insulating film therebetween; a second insulating film over the semiconductor film; a second electrode overlapping with the semiconductor film with the second insulating film therebetween; and a third insulating film over the second electrode; an organic light emitting diode over the third insulating film, the organic light emitting diode including an anode, an organic light emitting layer and a cathode; a fourth insulating film on and in contact with the organic light emitting diode; a first film comprising silicon nitride over the fourth insulating film; and a second film comprising silicon nitride over the first film, wherein the organic light emitting diode emits white light.
