Abstract
An optically anisotropic layered body including a first optically anisotropic layer and a second optically anisotropic layer, wherein in-plane retardations Re(H450), Re(H550), Re(H590), and Re(H650) of the first optically anisotropic layer at wavelengths of 450 nm, 550 nm, 590 nm, and 650 nm, respectively, and in-plane retardations Re(Q450), Re(Q550), Re(Q590), and Re(Q650) of the second optically anisotropic layer at wavelengths of 450 nm, 550 nm, 590 nm, and 650 nm, respectively, satisfy specific requirements.
