Abstract
Disclosed is a liquid crystal composition characterized by containing 15% by mass or more of a compound having a terminal structure represented by the general formula (I) below. This liquid crystal composition has high dielectric constant anisotropy (ε) and low rotational viscosity (γ1), and is thus suitably used as a liquid crystal composition for IPS liquid crystal displays or low voltage-driven TN liquid crystal displays. (I) (In the above formula, Q represents a saturated or unsaturated alkyl group having 1-8 carbon atoms which may be substituted by a halogen atom.)
