Patent ID: 7033848

Claim:
A method of manufacturing a light emitting device, comprising: forming a thin film transistor on an insulating surface; forming a first insulating film comprising an inorganic material over the thin film transistor; forming a second insulating film comprising an organic material over the first insulating film by application; forming a third insulating film comprising an inorganic material over the second insulating film by sputtering; forming a conducting film over the third insulating film, the conductive film serving as a first electrode of a light emitting element; forming the first electrode from the conductive film by first etching using a mask; pattering the third insulating film by second etching to form a patterned third insulating film, thereby exposing portion of the second insulating film; forming a contact hole in the first insulating film, the second insulating film, and a gate insulating film of the thin film transistor wherein the contact hole is located in the exposed portion of the second insulating film; forming a wire in the contact hole wherein the wire is brought into contact with the thin film transistor and the first electrode; forming an organic compound layer over the first electrode; and forming a second electrode of the light emitting element over the organic compound layer.
