Abstract: A display device may include a window, a display panel, and an adhesive resin layer. The window may include a front surface portion and a curved portion, which is extended from the front surface portion and is bent with a curvature. The display panel may be combined with the window, and may include a first region corresponding to the front surface portion and a second region corresponding to the curved portion. The adhesive resin layer may be interposed between the window and the display panel to fasten the display panel to a rear surface of the window. The adhesive resin layer may include a first attachment portion corresponding to the front surface portion and a second attachment portion corresponding to the curved portion, and a thickness of the second attachment portion may be different from a first thickness of the first attachment portion.

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.
