Abstract: Provided is a liquid crystal composition having a positive dielectric anisotropy, the liquid crystal composition containing two or more compounds selected from compounds represented by general formula (LC0-1) to general formula (LC0-3), and one or more compounds selected from groups of compounds represented by general formula (LC1) to general formula (LC5). The liquid crystal composition has features of a large Δ∈ and a low viscosity, and provides a practical, highly reliable liquid crystal display element that can realize low-voltage driving and high-speed response. The liquid crystal composition is useful for an active matrix driving liquid crystal display element. The liquid crystal composition can be applied to a liquid crystal display element of an IPS mode or the like.

Abstract: The present invention relates to a nematic liquid crystal composition useful as an electro-optic liquid crystal display material and having a positive dielectric anisotropy (Δ∈). The liquid crystal composition has refractive index anisotropy (Δn) adjusted to a desired level, a sufficiently low viscosity (η), and a positive dielectric anisotropy (Δ∈) while degradation of the temperature range of the nematic phase is avoided by suppressing the decrease in nematic phase-isotropic liquid phase transition temperature (Tni) and the increase in lower limit temperature of the nematic phase. The liquid crystal composition contains one or more compounds selected from compounds represented by general formula (LC0) and one or more compounds selected from a group of compounds represented by general formula (LC1) to general formula (LC5).
