Abstract: A display device includes a display module including non-folding areas arranged with each other in a first direction and a folding area between the adjacent non-folding areas, a hinge under the display module and configured to fold the display module with respect to the folding area, a supporter between the non-folding areas and the hinge, and a guide portion connected to the supporter and configured to be inserted into a guide groove defined in the hinge. A length in the first direction of the guide groove is obtained utilizing a length of an arc of the folding area when the display module is folded.
