Abstract
A laminate is provided from which a larger number of members suitable for head-mounted displays can be cut while suppressing ghosting. The laminate includes a first optically anisotropic film and a second optically anisotropic film. An average orientation of directions in which optical anisotropy of the first film is largest defines a first average orientation, and an average orientation of directions in which optical anisotropy of the second film is largest defines a second average orientation. A maximum deviation from the first average orientation is 0.5°-5.0°. An angle α between the first and second average orientations satisfies 10°<α<80°. An angle β between anisotropy directions of the films satisfies 0°<|β−α<1°.
