ABSTRACT:
An optical film according to the present invention comprises a transparent base, and an anti-reflection layer that is disposed on one main face of the transparent base. The anti-reflection layer includes 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. 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 the total weight of the hard coating layer. The hard coating layer is formed using a coating solution containing water in an amount of at least 0.05 wt % and at most 5.0 wt %.
