ABSTRACT:
There is provided an optical film obtained by laminating a polarizing film protective layer and a retardation film comprising a liquid crystalline compound layer, a retardation film protective layer and a polymer film, wherein the retardation film protective layer comprising a cured product of a UV-curable resin composition is inserted between the polymer film and the liquid crystalline compound layer to control or block the migration to the liquid crystalline compound layer of a material present in the polymer film and affecting the optical properties of the liquid crystalline compound layer by migrating to the liquid crystalline compound layer, in such a manner that the protective layer side of the polarizing film and the liquid crystalline compound layer side of the retardation film are opposed to each other.
