Abstract
An optical multilayer structure including a hard coating layer, an adhesion reinforcement layer, a low refractive layer, and a water repellent layer on a substrate layer. The optical multilayer structure includes a structure in which a hard coating layer, an adhesion reinforcement layer including an alkoxysilane-based compound having a functional group, a low refractive layer including a siloxane-based compound, and a water repellent layer including an alkoxysilane-based compound containing a fluorine atom are laminated on a substrate layer, thereby having both high wear resistance and water contact angle.
