Abstract: A display device includes a display part including a first non-folding area, a second non-folding area, and a folding area between the first non-folding area and the second non-folding area, the folding area being foldable with respect to a folding axis, a window disposed on the display part, and an adhesive layer disposed between the display part and the window, the adhesive layer including a first adhesive material and a second adhesive material having an elongation rate greater than an elongation rate of the first adhesive material. The first adhesive material has a planar area greater than a planar area of the second adhesive material in each of the first non-folding area and the second non-folding area, and the second adhesive material has a planar area greater than a planar area of the first adhesive material in the folding area.
