Claim Text:
1. A method of manufacturing a flexible display device, the method comprising: forming a buffer layer on a base substrate, wherein the buffer layer is transparent and has an optical bandgap of about 3.0 eV to about 4.0 eV; forming a flexible substrate on the buffer layer; forming display elements on the flexible substrate; forming a seal pattern between the flexible substrate and another flexible substrate opposing to the flexible substrate; hardening the seal pattern using an ultra-violet (UV) ray, while simultaneously injecting a liquid crystal layer between the flexible substrate and the another flexible substrate; and to ablating the buffer layer by a laser to completely remove the buffer layer from the flexible substrate and to detach the flexible substrate from the base substrate.
