1. A method for manufacturing a flexible display device, the method comprising:
forming a heat generator on a carrier substrate; forming a flexible substrate on a first surface of the heat generator, the flexible substrate being smaller than the heat generator such that at least first and second opposing ends of the heat generator extend beyond the flexible substrate, the heat generator having a surface area overlapping the flexible substrate greater than a surface area of the flexible substrate; forming a thin film transistor on the flexible substrate; forming a light emitting element connected to the thin film transistor; and separating the flexible substrate from the heat generator by applying heat to the flexible substrate, applying the heat including generating uniform heat over the whole heat generator by supplying a voltage to the first surface of the heat generator, wherein separating the flexible substrate from the heat generator includes applying the heat that provides an interface temperature between the heat generator and the flexible substrate that is greater than a melting point of the flexible substrate so that a part of the flexible substrate is decomposed by the heat.
