    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.

  • Patent number: 11981597
    Abstract: A display module includes a display panel and a window. The window includes a base substrate and a plurality of functional layers. A central portion of the base substrate is flat, and an edge portion of the base substrate has a rounded shape. An upper portion of the edge portion of the window has the rounded shape and thus protrudes from a lower portion of the edge portion toward the outside. A first functional layer of the plurality of functional layers includes an acrylic-based material and/or an epoxy-based material, and a second functional layer of the plurality of functional layers includes a fluorine-based material.

  • 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.
