OPTICAL ANISOTROPIC FILM AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Disclosed is an optical anisotropic film comprising at least one liquid crystalline compound. The at least one liquid crystalline compound develops a nematic or smectic phase, and has a birefringence index ?n (?) of the liquid crystal phase which satisfies the following formula (1) at a wavelength ?. In the optical anisotropic film, a molecule of the liquid crystalline compound is immobilized in an obliquely oriented state. Formula (1): ?n(450 nm)/?n(550 nm) < 1
