Abstract
A nematic liquid crystal composition of the present invention includes 10 to 80% by mass of either one or at least two compounds represented by general formula (I) as a first component; and 20 to 70% by mass of either one or at least two compounds represented by general formula (II) as a second component, wherein a dielectric constant anisotropy is negative. The use of this nematic liquid crystal composition can provide a highly reliable liquid crystal display element capable of maintaining a high voltage-holding ratio even in a high temperature region, and achieving quick responsiveness without reducing the cell gap.
