Abstract: An adhesive sheet including a first release film, a second release film disposed on the first release film, and an adhesive layer disposed between the first release film and the second release film, the adhesive layer including an upper surface facing the second release film, a lower surface facing the first release film, and a side surface extending from an edge of the lower surface to an edge of the upper surface. The side surface of the adhesive layer may be inclined with respect to a direction perpendicular to the upper surface and the lower surface.

Abstract: An optical clear resin includes a tetrahydrofuran (THF)-based oligomer having a glass transition temperature of about −50° C. or less, an acrylate-based monomer, and a photoinitiator. As the optical clear resin includes the tetrahydrofuran-based oligomer, the curing time of the optical clear resin is shortened and the modulus of elasticity of the optical clear resin is lowered.
