Patent ID: 8435423

Claim:
A liquid crystal composition that has a nematic phase and comprises four components, wherein a first component is at least one compound selected from the group of compounds represented by formula (1), a second component is at least one compound selected from the group of compounds represented by formula (2), a third component is at least one compound selected from the group of compounds represented by formula (3), and a fourth component is at least one compound selected from the group of compounds represented by formula (4): wherein R 1 , R 2 , R 4 and R 5 are each independently alkyl having 1 to 12 carbons or alkenyl having 2 to 12 carbons; R 3 is 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; the ring A and the ring B are each independently 1,4-cyclohexylene, 1,4-phenylene, 2-fluoro-1,4-phenylene, 3-fluoro-1,4-phenylene, 3,5-difluoro-1,4-phenylene or tetrahydropyran-2,5-diyl; X 1 , X 2 , X 3 , X 4 and X 5 are each independently hydrogen or fluorine; and Y 1 , Y 2 and Y 3 are each independently fluorine, chlorine or trifluoromethoxy.
