    Abstract: A display device includes a display module extending in a first direction, a supporting portion disposed under the display module and which supports a part of the display module, a first driving part connected to a first end of the display module to roll and unroll the display module, a connecting portion connected to a second end of the display module, and a second driving part connected to the connecting portion to roll and unroll the connecting portion. The second driving part unrolls the connecting portion when the first driving part rolls the display module, and the second driving part rolls the connecting portion when the first driving part unrolls the display module.

    Abstract: 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.
