Abstract

The present invention provides a liquid crystal composition including at least one compound represented by General Formula (1), at least one compound represented by General Formula (2), and at least one compound represented by General Formula (LC1). The liquid crystal composition of the present invention has high refractive index anisotropy (Δn) and sufficiently low viscosity (η), achieves a wide nematic phase temperature range by suppressing a decrease in nematic phase-isotropic liquid phase transition temperature (T), and exhibits high compatibility. By using the liquid crystal composition of the present invention in a liquid crystal display element, a liquid crystal display element having a high response speed and high practical reliability can be obtained.
