Optical anisotropic film |
| abstract |
An optically anisotropic film having an optical rotatory action and having a small wavelength dependency of the optical rotatory action in the visible light region is provided. An optically anisotropic film containing a liquid crystal compound that expresses a nematic phase or a smectic phase and has a birefringence Δn (λ) at a wavelength λ of the liquid crystal phase satisfies the following formula (1): In the optically anisotropic film, the molecules of the liquid crystal compound are fixed in an alignment state twisted in the thickness direction of the film. Formula (1) Δn (450 nm) / Δn (550 nm) <1 [Selection figure] None |
