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.
