Abstract:
1. A liquid crystal composition consisting essentially of: (a) a liquid crystal component consisting essentially of a first component that is at least one compound represented by formula (1) in the range of approximately 10% to approximately 35% by weight, a second component that is at least one compound represented by formula (2) in the range from approximately 26% to approximately 40% by weight, a third component that is at least one compound represented by formula (3) in the range from approximately 10% to approximately 45% by weight, and a fourth component that is at least one compound represented by formula (4) in the range from approximately 10% to approximately 55% by weight: wherein R 1 and R 2 are independently an alkyl group having 1 to 12 carbons; R 3 is an alkyl group having 1 to 12 carbons or an alkenyl group having 2 to 12 carbons; Y 1 is fluorine or —OCF 3 ; Y 2 is an alkyl group having 1 to 12 carbons, an alkoxy group having 1 to 12 carbons, fluorine, chlorine, or —OCF 3 ; X 1 is hydrogen or fluorine; A 1 is 1,4-cyclohexylene or 1,4-phenylene; A 2 is 1,4-cyclohexylene, 1,4-phenylene or 2,6-difluoro-1,4-phenylene; Z 1 is a single bond or —(CH 2 ) 2 —; Z 2 is a single bond, —(CH 2 ) 2 —, —COO—, or —CF 2 O—; and Z 3 is a single bond or —COO—; and (b) at least one non-liquid crystal component.
