A resin composition including at least one of a monofunctional (meth)acrylate having an imide ring structure or a monomer having a 2-pyrrolidone skeleton and a radical curable group in an amount of about 0.1 weight percent to about 5 weight percent based on the total weight of the resin composition, wherein the resin composition has a viscosity of about 5 millipascal seconds to less than about 50 millipascal seconds at 25° C., and wherein a glass transition temperature of the resin composition after being cured satisfies a value of about −50° C. to less than about 0° C. 1. A resin composition comprising:at least one of a monofunctional (meth)acrylate having an imide ring structure or a monomer having a 2-pyrrolidone skeleton and a radical curable group in an amount of about 0.1 weight percent to about 5 weight percent based on the total weight of the resin composition,wherein the resin composition has a viscosity of about 5 millipascal seconds to less than about 50 millipascal seconds at 25° C., andwherein a glass transition temperature of the resin composition after being cured is about −50° C. to less than about 0° C.2. The resin composition of claim 1 , wherein a 180° peel strength of the resin composition after being cured on glass or a polyimide film is about 1000 gram-force per 25 millimeter.3. The resin composition of claim 1 , further comprising a urethane (meth)acrylate oligomer claim 1 ,wherein the urethane (meth)acrylate oligomer is present in an amount of about 2 weight percent to about 15 weight percent based on the total weight of the resin composition.4. The resin composition of claim 1 , wherein the monofunctional (meth)acrylate of the resin composition comprises:at least one (meth)acrylate monomer having a molecular weight of about 1 to about 500 grams per mole, andat least one (meth)acrylate oligomer having a weight average molecular weight of about 6000 grams per mole or greater.5. The resin composition of claim 1 , further comprising an organic ...
