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.
