Patent ID: 7767276

Claim:
A liquid crystal composition, comprising: a first class comprising a fluorine-containing compound represented by chemical formula (I), and a second class comprising a first sub-class and a second sub-class, each of the first sub-class and the second sub-class comprising at least one of neutral liquid crystal compounds represented by chemical formula (III), chemical formula (IV), and chemical formula (V), wherein: each of W 1 and W 2 is a hydrogen atom or a fluorine atom, independently and at least one of W 1 and W 2 comprises a fluorine atom; each of A and B comprises at least one selected from the group consisting of a chain or ring alkyl group and a chain or ring alkoxy group; and the neutral liquid crystal compounds represented by chemical formula (III), chemical formula (IV), and chemical formula (V) comprise R 1 to R 6 as terminal groups, wherein each of R 1 to R 6 is one of a C 1 to C 12 alkyl group, alkoxy group, and alkenyl group; wherein the at least one neutral liquid crystal compound of the first sub-class does not have an alkenyl group as either terminal group thereof, and the at least one neutral liquid crystal compound of the second sub-class has an alkenyl group as a terminal group thereof, the second sub-class being contained at less than 7 wt % of the total content of the first and second classes, and wherein: the first class further comprises a fluorine-containing compound represented by chemical formula (II); wherein: each of W 1 , W 2 , and W 3 is a hydrogen atom or a fluorine atom, independently and at least one of W 1 , W 2 , and W 3 comprises a fluorine atom; and each of C and D comprises at least one selected from the group consisting of a chain or ring alkyl group and a chain or ring alkoxy group.
