Patent ID: 6853004

Claim:
An organic electroluminesence display device comprising: a resin substrate; an insulating film comprising a nitride on the resin substrate; and a thin film transistor formed over the insulating film, said thin film transistor comprising: a crystalline semiconductor layer formed over the insulating film and including at least a channel region, source and drain regions and a pair of lightly doped regions between the channel region and said source and drain regions; a gate insulator formed on the crystalline semiconductor layer; and a gate electrode formed over the channel region with the gate insulator interposed therebetween wherein boundaries between said channel region and said pair of lightly doped regions are aligned with side edges of the gate electrode, an interlayer insulating film comprising an organic resin over the thin film transistor; and an electroluminescent element electrically connected to said thin film transistor, said electroluminescent element having a light emitting layer comprising an organic material.
