Abstract
A film transferring method according to an embodiment of the present invention of transferring a film adhered to a substrate to a roller in a state that a first adhesion force between the roller and the film and a second adhesion force between the film and the substrate are substantially the same includes: a transporting step of transporting the substrate and the film of which a first adhesion surface formed on one surface is adhered to the substrate in a first direction; a close contacting step of closely contacting the front end of the second adhesion surface formed on the other surface of the film that is transported with the roller rotating in the first rotation direction; and a transferring step of peeling the film from the substrate and simultaneously transferring it to the roller by peeling the front adhesion surface of the first adhesion surface from the substrate, while simultaneously transferring the front end of the second adhesion surface to the roller and continuously transporting the substrate in the first direction, wherein a first weak adhesion force that is smaller than the second adhesion force is formed between the front adhesion surface and the substrate.
