Abstract: A protective window includes a flexible base film and a hard coating layer disposed on the flexible base film. The hard coating layer includes a silicone leveling agent and an inorganic antistatic agent. The coating layer includes an upper area and a lower area disposed between the upper area and the flexible base film, and a density of the inorganic antistatic agent in the lower area is greater than a density of the inorganic antistatic agent in the upper area.

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.
