Abstract:
An optical film having: a hard coat layer; an optically anisotropic layer; and a transparent support, wherein the optically anisotropic layer contains a liquid crystalline compound and a binder, the hard coat layer, the transparent support, and the optically anisotropic layer are laminated in this order, a surface of the optically anisotropic layer contains a fluorine-containing compound not forming covalent bond with the binder of the optically anisotropic layer, a surface of the optical film on the hard coat layer-formed side contains a fluorine-containing or silicone series compound being fixed by covalent bond, and a topmost surface properties of the optical film on hard coat layer-formed side satisfies the specific conditions.
