Abstract:
1. 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) and (2-2); and the third component is at least one compound selected from the group of compounds represented by Formulas (3-1), (3-2) and (3-3): wherein R 1 is alkenyl having approximately 2 to approximately 12 carbons, alkadienyl having approximately 4 to approximately 12 carbons, or alkenyl having approximately 2 to approximately 12 carbons, arbitrary hydrogen of which is replaced by fluorine; R 2 , R 3 and R 5 are each independently alkyl having approximately 1 to approximately 12 carbons, alkenyl having approximately 2 to approximately 12 carbons, or alkenyl having approximately 2 to approximately 12 carbons, arbitrary hydrogen of which is replaced by fluorine; R 4 is fluorine, alkyl having approximately 1 to approximately 12 carbons, or alkenyl having approximately 2 to approximately 12 carbons; R 6 is fluorine, chlorine, alkyl having approximately 1 to approximately 12 carbons, alkoxy having approximately 1 to approximately 12 carbons, or alkenyl having approximately 2 to approximately 12 carbons; Y 1 is fluorine or chlorine; Y 2 is fluorine or trifluoromethoxy; X 1 and X 5 are each independently hydrogen or fluorine; and X 2 , X 3 and X 4 are each independently hydrogen or fluorine, provided that at least one of X 2 , X 3 and X 4 is fluorine.
