Optically-Anisotropic Film and Liquid-Crystal Display Device
摘要:
A novel optically-anisotropic film is disclosed. The film is formed of a composition comprising at least one discotic liquid-crystal compound having a ratio, α1, which is a ratio of birefringence at 400 nm to birefringence at 550 nm in a liquid-crystal state, of less than 1.25, in which the molecules of the liquid-crystal compound are fixed in an alignment state at a mean tilt angle ranging from 35 to 85°, wherein its in-plane retardation Re, as measured in a direction normal to a plane of the optically-anisotropic film for 50 nm wavelength light, falls within the range from 60 nm to 220 nm.
