Abstract:
An optically anisotropic film is formed of a liquid crystal composition including a liquid crystal compound and has a liquid crystal alignment pattern in which a direction of an optical axis derived from the liquid crystal compound changes while continuously rotating in at least one in-plane direction of the optically anisotropic film, and the optically anisotropic film satisfies predetermined requirements.
