An object of the present invention is to provide a retardation film having excellent front contrast. A retardation film having an optically anisotropic layer in which a rod-like liquid crystal is vertically aligned and fixed on a transparent film, the optically anisotropic layer having a carboxyl group and a sulfone. Scattered light of a film containing a fluorine-based compound having at least one group selected from an acid group, a phosphoric acid group or a salt thereof, or an OH group, and the transparent film having an incident light of 90 ° in a scattered light profile of a goniophotometer In the intensity measurement, in the case of measuring the scattered light intensity at a position of 130 ° from the light source, the difference in scattered light intensity between the case where the film slow axis is installed horizontally on the sample stage and the case where the film is installed vertically, A retardation film characterized by being 0.05 or less.
