A display device includes a display panel that may be folded with reference to at least one folding axis, a polarization layer disposed on the display panel, an adhesive layer disposed on the polarization layer, and a window disposed on the adhesive layer, and having one surface facing the adhesive layer. A 180 degree (°) peel adhesion of the adhesive layer to the one surface of the window may be about 493 gram-force per inch (gf/inch) to about 817 gf/inch under the conditions of a temperature of about 60 degrees Celsius (° C.) and a relative humidity of about 93 percent (%). Accordingly, the display device including the adhesive layer may exhibit good durability, and maintain the reliability thereof.
