Abstract:
1. A method of manufacturing a display device comprising: forming a first material layer comprising a metal over a first substrate; forming a second material layer comprising an organic material over the first material layer; forming an insulating film on the second material layer; forming a circuit including a thin film transistor including a channel formation region over the insulating film, wherein the formation of the circuit includes a laser crystallization of a semiconductor film for the channel formation region of the thin film transistor; forming a first electrode electrically connected to the thin film transistor; forming a light emitting layer over the first electrode; forming a second electrode over the light emitting layer; attaching a second substrate over the second electrode, wherein the second substrate is flexible; separating a structure including at least the circuit, the first electrode, the light emitting layer, the second electrode, and the second substrate from the first substrate; and attaching a flexible substrate to the structure after separating the structure so that the insulating film is located between the structure and the flexible substrate.
