Adhesive member and display device including the same
Abstract:
An adhesive member includes a polymer derived from a resin composition. The resin composition includes at least one (meth)acrylate monomer, at least one urethane (meth)acrylate oligomer, and at least one photoinitiator. The adhesive member has a glass transition temperature in a range of about −70° C. to about −30° C., a 180° peel force of about 800 gf/25 mm or greater at a temperature of 25° C., and a deformation recovery rate in a range of about 75% to about 100% at temperatures of −20° C. and 60° C. The deformation recovery rate satisfies the following equation: X2=[1−(X1/25)]×100%, where X1 denotes a shear strain measured 600 seconds after removing a shear stress applied in a way such that the adhesive member has a shear strain of 25% at the temperatures of −20° C. and 60° C., and X2 denotes the deformation recovery rate.
