Abstract: A display device includes a display module and a folding set disposed below the display module and defining a first rotation axis and a second rotation axis, which each extend in the first direction. Here, a first axis parallel to the second direction and overlapping a first surface of the display module and a second axis perpendicular to the first surface of the display module at a center of the folding set are defined. Also, a first coordinate of the second rotation axis is determined by an equation (G/2)+T≤X≤(L/2). Here, X denotes the first coordinate, G denotes a distance between the first non-folding area and the second non-folding area of the display module, T denotes a thickness of the display module measured with respect to the second axis, and L denotes a length of the folding area.
