A display device may include a display panel including a folding area, first and second non-display areas, and first and second non-folding areas arranged in a first direction. A plurality of stress-relieving members are arranged in the first direction and are disposed on rear surfaces of the first and second non-display areas. The stress-relieving members may extend in a second direction crossing the first direction. First and second supporting members are disposed on rear surfaces of the first and second non-folding areas, respectively. When the display panel is folded along a folding axis overlapped with the folding area and extended in the second direction, the first and second non-display areas may be bent by surfaces of each of the stress-relieving members contacting each other, and a bending direction of each of the first and second non-display areas is opposite to a bending direction of the folding area.
