Abstract: A window includes a base layer and a hard coating layer on the base layer. The hard coating layer includes a first layer on the base layer and of a first thickness, and a second layer on the first layer and of a second thickness. The second layer includes an antistatic agent. The hard coating layer has a hardness reduction rate of 50 percent (%) or less expressed as follows. H = ( 1 - D 1 D 2 ) × 100 In the equation above, H is a hardness reduction rate (%) of a target layer, D1 is a hardness reduction rate measured from the target layer at a temperature of 60 degrees Celsius (° C.) with a relative humidity of 93%, and D2 is a hardness reduction rate measured from the target layer at a room temperature with a relative humidity of 30%.

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.
