Abstract
Disclosed herein is an organic light-emitting display device having a first flexible substrate; a second flexible substrate; a plurality of organic light-emitting pixels on the first flexible substrate and between the first flexible substrate and the second flexible substrate; an encapsulation unit covering the pixels; and an adhesive layer on the encapsulation unit. The Young's modulus of the adhesive layer is equal to or larger than a value so that the first flexible substrate is not deformed by bending stress when it is rolled up.
