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.

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 adhesive composition is disclosed that includes styrene, polybutadiene, sulfurous ester, isopropenyl toluene, and methylphenylacetylene. A cured product of the adhesive composition has a relative permittivity of at least about 2.0 but not more than about 2.5 wt %. Using the adhesive composition as an antenna film adhesive layer between a display panel and an antenna film or between a functional layer and the antenna film may provide a small thickness of the adhesive layer and improved reliability of a touch sensor and an antenna.
