Patent ID: 7871717

Claim:
An optical film, comprising: a transparent base; and an anti-reflection layer that is disposed on one main face of the transparent base, wherein the anti-reflection layer consists of a hard coating layer, and a low refractive index layer that is disposed on the hard coating layer in this order from the side of the transparent base, a thickness of the hard coating layer is 1 μm to 7 μm, the hard coating layer is formed using a resin containing an ionizing radiation setting resin, the hard coating layer contains a conductive metal oxide in an amount of at least 5 wt % and at most 30 wt % with respect to a total weight of the hard coating layer, wherein the conductive metal oxide is at least one selected from the group consisting of an antimony-tin oxide (ATO), an indium-tin oxide (ITO), a phosphorus-tin oxide (PTO), a zinc antimonite (ZnSb 2 O 6 ), and an antimony pentoxide (Sb 2 O 5 ), the hard coating layer is formed using a coating solution containing water in an amount of at least 0.3 wt % and at most 2.0 wt %, and a haze of the optical film is at most 0.8%.
