An optical adhesive composition includes a urethane (meth)acrylate resin having at least one hydroxyl group and at least one vinyl group, the urethane (meth)acrylate resin having a curing contraction ratio expressed by Equation 1 of about 0 to about 3%; and an adhesion of about 30 to about 80 kgf: Curing contraction ratio (%)=(A−B)/A×100,  [Equation 1] where A is a specific gravity of the optical adhesive composition before curing, and B is a specific gravity of the solid optical adhesive composition after curing.
