A retardation film comprising a transparent support, disposed on a surface thereof, an alignment layer and an optically anisotropic layer is disclosed. The transparent support and the optically anisotropic layer satisfy following relations: Re(DLC)<60 nm (1) (−0.5)×Re(TS)+40≰Re(DLC)≰(−0.5)×Re(TS)+80 (2) 0.5×Rth(TS)−10≰Re(DLC)≰0.5×Rth(TS)+30 (3) where Re(DLC) indicates retardation in plane of the optically anisotropic layer; Re(TS) indicates retardation in plane of the transparent support; and Rth(TS) indicates retardation along the thickness direction of the transparent support.
