Patent ID: 8508682

Claim:
A method for manufacturing a display device, the method comprising the steps of: forming a metal film and a metal oxide film over a first substrate; forming a peel-off layer over the metal film and the metal oxide film, the peel-off layer comprising a transistor, a first electrode in electrical contact with one of a source and a drain of the transistor, and an insulating layer; forming a water-soluble resin over the peel-off layer; fixing a tape over the water-soluble resin, the tape having a feature of deterioration in adhesiveness by being irradiated with an ultraviolet ray; separating the first substrate from the peel-off layer by using a physical means; fixing a second substrate under the peel-off layer by using an adhesive; irradiating an ultraviolet ray to the tape; separating the tape from the water-soluble resin; removing the water-soluble resin by using water; forming a light emitting layer on the peel-off layer by evaporation; forming a second electrode on the light emitting layer; forming a sealing film over the second electrode.
