Abstract
A nematic liquid crystal composition of the present invention includes one or at least two compounds represented by general formula (I) as a first component; and one or at least two compounds represented by general formula (II) as a second component, wherein a dielectric 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.
