  • Patent number: 11891467
    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.
