Abstract
A liquid crystal composition having a negative dielectric anisotropy that includes two components, wherein the first component is a specific two-ring compound having phenylene, two hydrogens of which are replaced by fluorine, and the second component is a specific four-ring compound having phenylene, one hydrogen of which is replaced by fluorine, and a liquid crystal display device including the composition.
