Patent ID: 7147530

Claim:
A method of manufacturing a display device comprising the steps of: forming a semiconductor film over a substrate; forming a first insulating film over the semiconductor film; forming a gate electrode over the first insulating film; forming a second insulating film over the gate electrode wherein the second insulating film has a contact hole; forming one of a source wiring and a drain wiring over the second insulating film wherein one of the source wiring and the drain wiring is electrically connected to the semiconductor film through the contact hole of the second insulating film; forming a third insulating film over one of the source wiring and the drain wiring; forming a fourth insulating film comprising a resin over the third insulating film; forming a fifth insulating film over the fourth insulating film; and forming an electroluminescence element over the fourth insulating film, said electroluminescence element comprising a first electrode formed in contact with the fifth insulating film, an electroluminescence layer formed over the first electrode by an ink jet method and a second electrode formed over the electroluminescence layer, wherein the electroluminescence layer is in contact with an upper surface of the fifth insulating film.
