Claim:
An optical film comprising: 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 by a roll to roll process, a surface of the optically anisotropic layer contains a fluorine-containing compound not forming any covalent bond with the binder of the optically anisotropic layer, a topmost surface of the optical film on the hard coat layer-formed side contains a fluorine- containing or silicone series compound being fixed by covalent bonding to the surface, the topmost surface properties of the optical film on the hard coat layer-formed side satisfy the following conditions: (1) Ra is 0.05 to 0.25 μm; (2) Rz is 0.4 to 3.0 μm; (3) Sm is 40 to 200 μm; (4) surface haze is 0.1 to 15; (5) internal haze is 0 to 28; and (6) total haze is 0.1 to 30; wherein Ra, Rz, and Sm represent, respectively, an arithmetic average roughness in a roughness curve profile of the topmost surface of the hard coat layer-formed side of the optical film, a ten point average roughness in the roughness curve, and a spacing between peaks in the roughness curve, wherein the optical film is wound up in a roll form, wherein the optically anisotropic layer containing a liquid crystalline compound is provided, directly or through an alignment layer, at one side of the transparent support and the hard coat layer is provided directly on the other side of the transparent support, and wherein a surface free energy of the optically anisotropic layer (Elc) and a surface free energy of the topmost surface of the optical film on the hard coat layer-formed side (Ehc) have a relationship of Ehc-Elc≦0.
