Abstract: A display device may include a first non-folding region, a second non-folding region, and a folding region. The display device may include a display member including a display module, a supporting member supporting the display member, an adhesion member disposed between the display member and the supporting member, and a compensation member attached to one of top and bottom surfaces of the adhesion member and overlapped with the folding region. Thus, it may be possible to provide a display device configured to reduce a stress, which is exerted on a folding region when it is in a folded state, and to prevent the folding region from being deformed to a bent shape when it is in an unfolded state.
