Claim:
A liquid crystal composition that has a nematic phase and contains 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, and contains no cyano compound among other liquid crystal compounds: wherein R 1 is alkyl having 1 to 12 carbons; R 2 is alkyl having 1 to 12 carbons or alkoxy having 1 to 12 carbons; R 3 is alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons or alkenyl having 2 to 12 carbons, or alkenyl having 2 to 12 carbons in which arbitrary hydrogen is replaced by fluorine; ring A is independently 1,4-cyclohexylenc or tetrahydropyran-2,5-diyl; ring B is independently 1,4-cyclohexylene, 1,4-phenylene, 2-fluoro-1,4-phenylene, 3-fluoro-1,4-phenylene, 3,5-difluoro-1,4-phenylene, 2,5-pyrimidine, 1,3-dioxane-2,5-diyl or tetrahydropyran-2,5-diyl; X 1 and X 2 are independently hydrogen or fluorine; Y 1 is fluorine, chlorine or trifluoromethoxy; Z 1 is independently a single bond, ethylene, carbonyloxy or difluoromethyleneoxy; m is 1 or 2; and n is 1, 2, 3 or 4.
