Abstract:
1. A liquid crystal composition having a negative dielectric anisotropy comprising three components, wherein the first component is at least one compound selected from the group of compounds represented by Formulas (1-1) to (1-6), the second component is at least one compound selected from the group of compounds represented by Formula (2), and the third component is at least one compound selected from the group of compounds represented by Formulas (3-1) and (3-2): wherein R 1 and R 2 are each independently alkyl having 1 to 12 carbons, alkoxy having from 1 to 12 carbons, alkenyl having 2 to 12 carbons or alkenyl having 2 to 12 carbons, arbitrary hydrogen of which are replaced by fluorine; R 3 to R 5 are each independently alkyl having 1 to 12 carbons, alkoxy having from 1 to 12 carbons, alkenyl having 2 to 12 carbons or alkenyl having 2 to 12 carbons, arbitrary hydrogen of which are replaced by fluorine; X 1 and X 2 are each independently fluorine or chlorine, provided that at least one of X 1 and X 2 is fluorine; Z 1 and Z 2 are each independently a single bond, —CH 2 CH 2 — or —CH═CH—; Z 3 to Z 6 are each independently a single bond or —CH 2 CH 2 —; and ring A, ring B, ring C and ring D are each independently 1,4-cyclohexylene or 1,4-phenylene.
