Abstract: A display device includes a display module including a first non-folding area, a second non-folding area, and a folding area disposed between the first and second non-folding areas which are arranged in a first direction, a first support disposed below the first non-folding area, a second support disposed below the second non-folding area, and a hinge including a biaxial rotation shaft disposed between the first support and the second support, the biaxial rotation shaft extending in a second direction intersecting the first direction. The folding area has a curvature radius in a range of about 1.5 mm to about 5.0 mm when the display module is folded by a rotation of the first support and the second support with respect to the biaxial rotation shaft.
