Patent ID: 7714950

Claim:
A method for manufacturing a display device comprising: forming a metal film over a first substrate; forming a semiconductor element over the metal film; forming a first electrode electrically connected to the semiconductor element; forming an insulating film covering an end of the first electrode; forming a light emitting layer over the first electrode; forming a second electrode over the light emitting layer; forming an ultraviolet (UV) protective film on the second electrode; fixing a second substrate over the UV protective film using a first adhesive; separating the metal film and the first substrate; and separating the first adhesive and the second substrate, and fixing a third substrate under the semiconductor element using a second adhesive, wherein separating the first adhesive and the second substrate, and fixing the third substrate are conducted at the same time by radiating an ultraviolet ray and heating; wherein a metal oxide film is formed in contact with the metal film.
