Abstract: Provided is a resin composition including at least one (meth)acrylate monomer, a urethane (meth)acrylate oligomer, and at least one photo initiator. The urethane (meth)acrylate oligomer includes a phosphate ester group and is represented by Formula 1. Accordingly, the resin composition may exhibit satisfactory compatibility before curing and may exhibit excellent adhesion after curing.

Abstract: A resin composition may include at least one urethane (meth)acrylate oligomer, at least one (meth)acrylate monomer, and at least one photoinitiator. The urethane (meth)acrylate oligomer may include a first urethane (meth)acrylate oligomer derived from a phosphate ester-containing polyol represented by Formula 1, and the first urethane (meth)acrylate oligomer may have a number-average molecular weight of about 805 to about 955. Accordingly, the resin composition may exhibit the characteristics of a low viscosity before being cured, and excellent or suitable shear modulus and peel strength after being cured.
