Abstract: A resin composition of an embodiment may include at least one oligomer, a plurality of monofunctional acrylate monomers, and at least one photoinitiator. The plurality of monofunctional acrylate monomers may include first to third acrylate monomers. The first monofunctional acrylate monomer includes a hydroxy group, and may have a weight of 5 wt % to 20 wt % based on the total weight of the resin composition. The second monofunctional acrylate monomer includes a branched alkyl group having 10 to 20 carbon atoms, and may have a weight of 25 wt % to 40 wt % based on the total weight of the resin composition. The third monofunctional acrylate monomer includes a non-aromatic ring group, and may have a weight of 20 wt % to 30 wt % based on the total weight of the resin composition. Accordingly, the resin composition of an embodiment may exhibit suitable discharge stability, and may exhibit suitable adhesion reliability.

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.
