METHOD OF MANUFACTURING TRANSPARENT FLEXIBLE DISPLAY DEVICE AND TRANSPARENT FLEXIBLE DISPLAY DEVICE MANUFACTURED USING THE METHOD

摘要

A method of manufacturing a transparent flexible display device includes forming a protection layer on a first surface of a transparent substrate, forming a transparent polymer layer on the protection layer, forming an amorphous silicon pattern on the transparent polymer layer, irradiating a first laser on the amorphous silicon pattern to dehydrogenate the amorphous silicon pattern, irradiating a second laser on the dehydrogenated amorphous silicon pattern to form a polycrystalline silicon pattern, forming a metal pattern on the polycrystalline silicon pattern, forming a display element electrically connected to the metal pattern, and irradiating a third laser on a second surface of the transparent substrate to separate the transparent polymer layer from the protection layer.
