A pre-laid polymer waterproof rolling material, which comprises a sheet-like polymer carrier, a hot-melt pressure-sensitive adhesive layer on the sheet-like polymer carrier, and a plurality of anti-sticking particles on the hot-melt pressure-sensitive adhesive layer, wherein the particle size of the anti-sticking particles is smaller than the thickness of the hot-melt pressure-sensitive adhesive layer; the surface of the anti-sticking particles is coated with an organic layer; and the anti-sticking particles are connected with the hot-melt pressure-sensitive adhesive layer by means of the organic layer; the organic layer comprises the following components: a solvent, a polyurethane resin, a pigment, a filler, a cross-linking agent, an antioxidant, an anti-ultraviolet agent and a thickener. The anti-sticking particles will not shed during transportation and will not be trapped into the hot-melt pressure-sensitive adhesive layer, such that the hot-melt pressure-sensitive adhesive layer is exposed to the outside.

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° C. to 80° 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.

An adhesive sheet comprising a hot-melt adhesive layer. The hot-melt type adhesive layer comprises a modified polymer (A) to which a cross-linkable group is bonded and a polyolefin (B). The adhesive sheet can adhere to various adherends and the adhesive becomes less likely to squeeze out from an adherend in thermal fusion bonding and sealing of the adherend. In a laminate comprising the adhesive sheet the adhesive layer does not squeeze out from the adherend without being affected by the material of the adherend.
