Provided is an optical film with excellent hardness and low moisture permeability, which is favorable as a polarizing plate protection film. Also provided are a polarizing plate showing low deterioration by moisture absorption, and a liquid crystal display device. Furthermore, provided is a method for producing an optical film with excellent hardness and low moisture permeability. The optical film (the polarizing plate protection film) (110) is an optical film comprising a hard coating layer (112) on a substrate (111), and the hard coating layer (112) is formed by curing, on the substrate, a composition composed of epoxide represented by chemical formula 1, a bisphenol compound, and an optical cation polymerization initiator. |
