Abstract
An optically anisotropic layered body including a first optically anisotropic layer and a second optically anisotropic layer, wherein each of refractive indices of the second optically anisotropic layer, in-plane retardations of the first optically anisotropic layer, thickness direction retardations of the second optically anisotropic layer, in-plane retardations of the optically anisotropic layered body, NZ factors of the optically anisotropic layered body, and thickness direction retardations Rth of the optically anisotropic layered body satisfies specific relationships.
