摘要： A laminate includes a substrate, a self-healing layer on the substrate and having a thickness of greater than or equal to about 50 micrometers, a protective layer between the substrate and the self-healing layer, and a surface layer on the self-healing layer and having a thickness of about 20 nanometers to about 300 nanometers, wherein the self-healing layer has a first elastic modulus and the protective layer has a second elastic modulus, wherein the second elastic modulus is about 1.2 times to about 50 times greater than the first elastic modulus, and wherein the surface layer has a friction coefficient of less than or equal to about 1.
