Abstract:
1. A liquid crystal composition comprising: a first class comprising a fluorine-containing liquid crystal compound represented by Formula I, where (n=1, 2, or 3), and a second class comprising at least one neutral liquid crystal compound represented by Formulae III, IV, and V: wherein W 1 and W 2 are independently one selected from the group consisting of —F, —CF 3 , —CF 2 H, —OCF 3 , and —OCF 2 H, the liquid crystal compounds represented by Formulae I, III, IV, and V have R a first sub-class or a second sub-class, the first sub-class has n=1 and a content of about 6 wt % or less based on the total content of the first class and the second class, the second sub-class having n=2 or 3, and a third sub-class or a fourth sub-class, the fourth sub-class having the alkenyl group in the terminal groups of the second class and having a content of about 7 wt% or less based on the total content of the first class and the second class, and the third sub-class not having the alkenyl group in the terminal groups of the second class.
