ABSTRACT OF THE DISCLOSURE By using an optically anisotropic film having the optical axis substantially parallel to the normal line of the film and comprising a polymer of a liquid crystal oligomerhaving positive anisotropy of refractive index and showing nematic or smectic phase, or by lamining the optically anisotropic film and a trans- parent or semitransparent polymer film, or by combining the optically anisotropic film with a uniaxially oriented retardation film, it is possible to obtain a composite retardation plate with a large viewing angle, and this retardation plate can be applied to a liquid crystal display device.
