Provided are a method for manufacturing a flexible display apparatus, which allows for easy separation of a flexible substrate from its supporting carrier as well as allowing easy handling of the flexible substrate during processing of the flexible substrate while it is on its supporting carrier. Also provided is a flexible display apparatus manufactured by the method. The method includes forming an adhesive layer including a metallic tin where the adhesive layer is disposed on a supportive carrier and disposing a flexible substrate on the adhesive layer such that the flexible substrate is affixed to the supporting carrier with the adhesive layer interposed therebetween. The method further includes separating the flexible substrate from the carrier by transformatively stressing (disintegration-wise stressing) the adhesive layer for example by means of temperature lowering.
