Abstract: A display device includes a display panel including a folding area and non-folding areas respectively extending from the folding area along a first direction; and a folding member which is foldable together with the display panel, the folding member including: a film layer corresponding to each of the folding area and the non-folding areas of the display panel, the film layer defining a storage space in which a fluid is disposed; and a pair of roller members each in slidable contact with the film layer, each of the pair of roller members slidable along the first direction. Unfolding of the display device moves each of the pair of roller members along the first direction toward the folding area, and folding of the display device moves each of the pair of roller members along the first direction away from the folding area.
