Patent ID: 8361569

Claim:
A liquid crystal composition that has a nematic phase and includes at least one compound selected from the group of compounds represented by formula (1) as a first component and at least one compound selected from the group of compounds represented by formula (2) as a second component, wherein the ratio of the first component is in the range of 3% by weight to 30% by weight, based on the total weight of the liquid crystal composition: wherein R 1 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 in which arbitrary hydrogen is replaced by fluorine; Z 1 and Z 2 are independently a single bond, ethylene or carbonyloxy; X 1 , X 2 , X 3 , X 4 , X 5 and X 6 are independently hydrogen or fluorine; and Y l is fluorine, chlorine or trifluoromethoxy.
