Abstract
An optical coating structure includes a substrate, an anti-reflective coating layer, a base coating layer, an antibacterial coating layer, and a protective coating layer. The anti-reflective coating layer is disposed on the substrate. The anti-reflective coating layer covers the substrate. The base coating layer covers the anti-reflective coating layer. The antibacterial coating layer is disposed on the base coating layer, and the antibacterial coating layer is an interlayer. The protective coating layer covers the antibacterial coating layer. A super-hydrophobic coating layer or an anti-fingerprint coating layer may cover the protective coating layer.
