Abstract: The nematic liquid crystal composition according to the present invention is used for, for example, producing a liquid crystal display element used in TN mode, OCB mode, ECB mode, IPS mode, or VA-IPS mode. The liquid crystal composition has a positive dielectric anisotropy and allows reductions in refractive-index anisotropy and nematic phase-isotropic liquid phase transition temperature and an increase in the lower limit temperature of a nematic phase to be suppressed. As a result, the liquid crystal composition has a sufficiently low viscosity without deteriorating the temperature range of a nematic phase. The liquid crystal composition allows high-speed response and high display quality to be realized, suppresses faulty display, and is suitably used as a practical liquid crystal composition.
