An adhesive film and a method of fabricating a flexible display using the same are provided. The adhesive film includes: a support including a first surface disposed opposite to a flexible substrate for forming an image display element and a second surface disposed opposite to a support substrate for supporting the flexible substrate; a first adhesive material applied on the first surface of the support; and a second adhesive material applied on the second surface of the support and having a greater adhesive strength than the first adhesive material. The flexible substrate can be easily detached from the support substrate, so that the flexible display can be realized in various sizes and thicknesses using existing equipment without modification of mass-production equipment for realizing the flexible display.
