Abstract: A photocurable composition includes: a photocurable oligomer; a photocurable monomer including a monofunctional (metha)acrylate monomer and a polyfunctional (metha)acrylate monomer; a functional raw material including an antioxidant and a surface additive; and a photoinitiator. The photocurable oligomer may include at least one of (metha)acrylate, polyester-based (metha)acrylate, epoxy (metha)acrylate, or urethane (metha)acrylate. The photocurable oligomer may be included in an amount of about 15 wt % to about 25 wt %, based on a total weight of the photocurable composition, and have a weight-average molecular weight of about 500 g/mol to about 10000 g/mol.
