Abstract: A method of manufacturing a flexible display device includes forming a graphene adhesive layer on a carrier substrate, forming a flexible substrate on the graphene adhesive layer, forming a first barrier layer on the flexible substrate, forming a display element part on the first barrier layer, forming a protective film on the display element part, separating the flexible substrate from the carrier substrate, removing a remaining portion of the graphene adhesive layer from a surface of the flexible substrate, and forming a second barrier layer on the surface of the flexible substrate, after removing the remaining portion of the graphene adhesive layer from the surface of the flexible substrate.

Abstract: A method of manufacturing a flexible display apparatus includes: preparing a substrate; forming a first charge adhesive layer having a first charge on the substrate; forming a second charge adhesive layer having a second charge, which is opposite to the first charge, on the first charge adhesive layer; forming a first charge adhesive pattern and a second charge adhesive pattern by removing an edge of each of the first charge adhesive layer and the second charge adhesive layer; forming a flexible substrate on the substrate on which the first charge adhesive pattern and the second charge adhesive pattern are formed; forming a display unit on the flexible substrate; cutting the substrate, the first charge adhesive pattern, the second charge adhesive pattern, the flexible substrate, and the display unit along a cutting line; and separating the substrate and the flexible substrate.

Abstract: A method of manufacturing a flexible display apparatus includes forming a flexible substrate on a carrier substrate, forming a display on a central portion of the flexible substrate, forming a protection layer covering the display, within an area of the flexible substrate, such that an edge portion of the flexible substrate is exposed outside of the protection layer, cutting a first edge portion of the flexible substrate that is exposed outside of the protection layer, except for a second remaining portion of the flexible substrate that is exposed outside of the protection layer, applying suction to the second portion of the flexible substrate, and separating the carrier substrate from the flexible substrate.
