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.
