ABSTRACT:
A liquid crystal composition and a liquid crystal display including the liquid crystal composition that includes a first class containing a fluorine-containing liquid crystal compound represented by Formula I (n=1, 2, or 3), and a second class containing at least one neutral liquid crystal compound represented by Formulae III, IV, and V. In Formula I, W1and W2are each independently selected from the group consisting of —F, —CF3, —CF2H, —OCF3, and —OCF2H, the liquid crystal compounds represented by Formulae I, III, IV, and V have R1, R2, and R5to R10that are any one of a hydrogen atom, and an alkyl group, an alkoxy group, and an alkenyl group having 1 to 12 carbon atoms as terminal groups, and a first sub-class has a content of 6 wt % or less based on a total content of the first class and the second class, with the proviso that a liquid crystal compound of the first class having n=1 is the first sub-class and a liquid crystal compound of the first class having n=2 or 3 is a second sub-class.
