The invention provides a low moisture permeability film which can provide an optical film with low moisture permeability and good brittleness, the optical film that a hard coat layer is further disposed on the low moisture permeability film and has low moisture permeability and good brittleness, a polarizing plate using the optical film, a liquid crystal display device using the polarizing plate and excellent in plate image quality in the high-temperature and high-humidity environment after a lapse of time, and a method of producing the low moisture permeability film. A low moisture permeability film has a layer formed by curing a curable composition on a substrate film. The curable composition includes the following (A) of 50 mass%-99 mass% and the following (B) of 1 mass%-30 mass% relative to the total solid components of the curable composition of 100 mass%: (A) at least one of a compound having an aliphatic hydrocarbon group and the ethylenically unsaturated double bonds, and a compound having a fluorine
