Abstract: A display device includes a display panel rollable about a rolling axis extending in a first direction, and a support member facing the display panel and rollable together with the display panel. The support member includes a support layer defining an upper surface of the support member and a lower surface of the support member which is opposite to the upper surface and further from the display panel than the upper surface, and a plurality of support bars within the support layer and each extending in the first direction, the plurality of support bars being arranged in a second direction crossing the first direction. Within the support layer, each of the plurality of support bars is convexly curved toward the upper surface of the support member, along the first direction.
