Abstract
An optical compensatory film of a laminated structure comprising a first optically anisotropic layer having an Re(550) of 20 to 100 nm wherein retardation at a wavelength of 550 nm is never 0 nm along any direction and the direction along which the absolute value of retardation at a wavelength of 550 nm reaches minimum does not exist along the normal direction of the layer or on the in-plane of the layer; and a second optically anisotropic layer having an Re(550) of 20 to 150 nm and an Rth(550) of 40 to 110 nm with Re(450) Re(550)<−3 nm and Rth(450)−Rth(550)>3 nm.
