Abstract
A foldable display device is disclosed. The foldable display device includes a display panel including a folding area and a non-folding area, a back plate unit, and a plurality of adhesive layers disposed between the display panel and the back plate unit and between the back plate units. Some of the plurality of adhesive layers includes a first adhesive part and a second adhesive part having different adhesiveness. Therefore, an adhesiveness of the plurality of adhesive layers is controlled to reduce the stress generated at the time of folding the foldable display device.
