Patent ID: 7470456

Claim:
A liquid crystal composition having a nematic phase comprising three components, wherein the first component is at least one compound selected from the group of compounds represented by Formula (1), the second component is at least one compound selected from the group of compounds represented by Formulas (2-1) to (2-3), and the third component is at least one compound selected from the group of compounds represented by Formula (3): wherein R 1 is alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons, alkoxyalkyl having 2 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 2 , R 3 and R 5 are each independently alkyl 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; R 4 is fluorine, alkyl having 1 to 12 carbons or alkenyl having 2 to 12 carbons; R 6 is fluorine, chlorine, alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons or alkenyl having 2 to 12 carbons; R 7 and R 8 are each independently alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons, alkenyl having 2 to 12 carbons, alkadienyl having 4 to 12 carbons or alkenyl having 2 to 12 carbons, arbitrary hydrogen of which are replaced by fluorine; Y 1 is fluorine, —OCF 3 or —OCHF 2 ; and X 1 , X 2 , X 3 , X 4 , X 5 and X 6 are each independently hydrogen or fluorine, provided that at least one of X 4 , X 5 and X 6 is fluorine.
