Beschreibung
Zusammenfassung:	The present invention is a liquid crystal composition having negative dielectric anisotropy containing one or two or more of compounds represented by General Formula (i), and is also a liquid crystal display element using the liquid crystal composition. The problem to be solved by the present invention is to provide a liquid crystal composition with a large refractive index anisotropy (Δn), a low rotational viscosity (γ1), a large elastic constant (K33), a high voltage holding ratio (VHR), and which has a negative dielectric anisotropy (Δε), and a liquid crystal display element which, when using the liquid crystal composition, has a high response speed with excellent display quality in which display defects such as drop marks, burn-in, and display unevenness are absent or suppressed.
