DISPLAY DEVICE

Abstract:

A display device including a display panel, a variable adhesive layer disposed on the display panel and a cover member disposed on the variable adhesive layer is provided. The variable adhesive layer includes a block copolymer and a plasticizer mixture, and the plasticizer mixture has a low critical solution temperature (LCST) of 60.degree. C. to 80.degree. C. The plasticizer mixture is phase-separated into two phases at a temperature equal to or higher than the low critical solution temperature, thereby significantly lowering adhesion of the variable adhesive layer. Accordingly, the display device of the present disclosure has excellent adhesion reliability and provides an advantage of easy reworking since the adhesion significantly decreases at a temperature equal to or higher than the low critical solution temperature. In addition, the display device has excellent folding characteristics due to the presence of the plasticizers.
