Abstract: A display device includes: a display panel; a window disposed on the display panel; a window protection layer disposed on the window; and a first adhesive layer disposed between the window and the window protection layer; wherein the first adhesive layer has a creep value of about 38.1876% to about 40.4371% at a temperature of about 25° C. when a stress of about 2,000 Pa is applied to the first adhesive layer for about 10 minutes, the first adhesive layer has a storage modulus of about 0.0317 MPa to about 0.0348 MPa, a loss modulus of about 0.0108 MPa to about 0.0120 MPa, and a tan delta value of about 0.3354 to about 0.3480 at the temperature of about 25° C. when a frequency of about 1 Hz and an axial force of about 1.0 N are applied and the first adhesive layer maintains a strain of about 1%, and the tan delta value is defined by dividing the loss modulus by the storage modulus.

Abstract: 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.
