Abstract
A nematic liquid crystal composition of the present invention is used in liquid crystal display devices of the TN mode, OCB mode, ECB mode, IPS mode, or VA-IPS mode. The liquid crystal composition has positive dielectric anisotropy. Since the refractive index anisotropy and the nematic phase-isotropic liquid phase transition temperature are decreased and the increase in the lower limit temperature of the nematic phase is suppressed, the viscosity of the liquid crystal composition is sufficiently low without degrading the nematic phase temperature range. The liquid crystal composition also offers excellent features such as high-speed response, good display quality, and less display failures and is thus suitable as a practical liquid crystal composition.
