Abstract: A display device includes a flexible substrate including a folding area, a non-folding area adjacent to the folding area along a first direction, and a first surface in both the folding area and the non-folding area, a light-emitting element layer on the flexible substrate, and a support which faces the light-emitting layer with the flexible substrate therebetween, forms an interface with the first surface of the flexible substrate and is bendable together with the flexible substrate. The support includes a first support corresponding to the folding area, a second support corresponding to the non-folding area, and a through hole extended through the support. The through hole is extended through the first support, and a first portion of the first surface of the flexible substrate is exposed to outside the support by the through hole in the first support.
