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 (1-4), the second component is at least one compound selected from the group of compounds represented by Formulas (2-a) to (2-c), and the third component is at least one compound selected from the group of compounds represented by Formula (3): wherein R 1 , R 3 and R 5 are each independently alkyl having 1 to 12 carbons or alkenyl having 2 to 12 carbons; R 2 and R 4 are each independently alkyl having 1 to 12 carbons, alkenyl having 2 to 12 carbons or alkoxy having 1 to 12 carbons; R 6 is independently alkyl having 1 to 12 carbons, alkoxy having 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; ring A and ring B are each independently 1,4-cyclohexylene or 1,4-phenylene; Z 1 , Z 2 , Z 3 and Z 4 are each independently a single bond, —C 2 H 4 — or —CH 2 O—; and X 5 , X 6 , X 7 , X 8 , X 9 and X 10 are each independently fluorine or chlorine, provided that X 5 and X 6 are not simultaneously chlorine, X 7 and X 8 are not simultaneously chlorine, and X 9 and X 10 are not simultaneously chlorine.
