1. A display device comprising:
a display module comprising a first non-folding area, a second non-folding area, and a folding area between the first and second non-folding areas; and
a folding set disposed on a first surface of the display module and defining a first rotation axis and a second rotation axis, which each extend in a first direction,
wherein the folding area and the first and second non-folding areas are arranged in a second direction crossing the first direction, and a first axis parallel to the second direction and overlapping a second surface of the display module opposite to the first surface of the display module and a second axis perpendicular to the surface of the display module at a center of the folding set are defined,
wherein a first coordinate of the second rotation axis is determined by an equation below:
(G/2)+T≤X≥(L/2),
wherein X denotes the first coordinate, G denotes a distance between the first non-folding area and the second non-folding area when the display module is folded, T denotes a thickness of the display module measured with respect to the second axis, and L denotes a length of the folding area with respect to the second direction, wherein when the display module is unfolded, the first and second rotation axes overlap a second surface of the display module opposite to the first surface of the display module, and when the display module is folded, the folding area is disposed above the first and second rotation axes.
