Abstract
An optical multilayer structure including a hard coating layer, a low-reflective adhesion reinforcement layer, and a water repellent layer on a substrate layer. The optical multilayer structure includes a structure in which a hard coating layer, a low-reflective adhesion reinforcement 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 high wear resistance and water contact angle simultaneously.
