Abstract: To provide an optically-compensatory film that can improve the contrast, to provide a polarizing plate and a liquid crystal display including the optically-compensatory film and a method of producing the optically-compensatory film. An optically-compensatory film including a transparent support; and at least one optically anisotropic layer including a liquid crystal composition containing liquid crystal compounds, in the transparent support; wherein when the optically-compensatory film is disposed between two polarizing plates in a cross nicol state, degree of depolarization as seen from the front face is 0.000022 or less, and degree of depolarization as seen from a polar angle of 50° from an absorption axis direction of one of the polarizing plates is 0.00077 or less.
