Abstract
The present invention provides a liquid crystal composition having positive dielectric anisotropy and containing at least one compound represented by general formula (LC0): and at least one compound represented by general formula (LC1):RA-ZA-Z-A-R  (LC1)The liquid crystal composition according to the present invention has refractive index anisotropy (Δn) adjusted to the desired level and a decrease in nematic phase-isotropic liquid phase transition temperature (T) and an increase in the nematic phase lower limit temperature are suppressed so as to achieve a sufficiently low viscosity (η) without degrading the nematic phase temperature range. When the liquid crystal composition of the present invention is used to produce a liquid crystal display device, a highly practical and highly reliable liquid crystal display device with high response speed and capacity for low-voltage drive is obtained.
