ABSTRACT:
Liquid crystal compositions which have excellent miscibility at low temperatures, a properly large optical anisotropy, and a small threshold voltage while satisfying various characteristics required of liquid crystal compositions for active matrix mode liquid crystal display devices. The compositions contain, as a first component, at least one compound expressed by any one of formulas ##STR1## and as a second component, at least one compound expressed by any one of formulas ##STR2## wherein R represents a straight chain alkyl group having 1 to 10 carbon atoms, X represents CF.sub.3 or OCF.sub.3, X.sup.2 represents fluorine or OCF.sub.3, each Y represents, independently of each other, a hydrogen or fluorine atom, and m is 1 or 2.
