摘要： A foldable display device is capable of improving a strength of a folding area and substantially reducing or minimizing a dead space of a non-folding area. The foldable display device includes: a display panel including a folding area and a non-folding area, and having a front surface and a back surface that are opposite each other; a window adjacent the front surface of the display panel; an auxiliary layer adjacent the back surface of the display panel; a first adhesive layer between the display panel and the window; and a second adhesive layer between the display panel and the auxiliary layer. A width of the window at the folding area is greater than a width of the window at the non-folding area.

摘要： A window includes a folding portion foldable with respect to an imaginary folding axis extending in a first direction, a first non-folding portion, and a second non-folding portion spaced apart from the first non-folding portion in a second direction perpendicular to the first direction with the folding portion interposed therebetween. The folding portion includes a base portion and a plurality of protrusion portions disposed on the base portion and spaced apart from each other in the second direction. A width, in the first direction, of the folding portion is smaller than a width, in the first direction, of each of the first non-folding portion and the second non-folding portion.
