Abstract:
Shown are a liquid crystal composition satisfying at least one of characteristics such as high maximum temperature, low minimum temperature, low viscosity, suitable optical anisotropy and large negative dielectric anisotropy, or having a suitable balance regarding at least two of the characteristics, and an AM device including the composition. The liquid crystal composition contains a specific compound having large negative dielectric anisotropy as a first component, and a specific compound having low viscosity as a second component, and may contain a specific compound having negative dielectric anisotropy as a third component, a specific compound having high maximum temperature or low viscosity as a fourth component, or a specific compound having a polymerizable group as an additive.

Claim (Index 5):
The liquid crystal composition according to  claim 1 , containing at least one compound selected from compounds represented by formula (3) as a third component: wherein, in formula (3), R 5  and R 6  are independently alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons, alkenyl having 2 to 12 carbons, alkenyloxy having 2 to 12 carbons, or alkyl having 1 to 12 carbons in which at least one hydrogen is replaced by fluorine or chlorine; ring B and ring D are independently 1,4-cyclohexylene, 1,4-cyclohexenylene, 1,4-phenylene, tetrahydropyran-2,5-diyl, 1,4-phenylene in which at least one hydrogen is replaced by fluorine or chlorine, naphthalene-2,6-diyl, naphthalene-2,6-diyl in which at least one hydrogen is replaced by fluorine or chlorine, chroman-2,6-diyl, or chroman-2,6-diyl in which at least one hydrogen is replaced by fluorine or chlorine; ring C is 2,3-difluoro-1,4-phenylene, 2-chloro-3-fluoro-1,4-phenylene, 2,3-difluoro-5-methyl-1,4-phenylene, 3,4,5-trifluoronaphthalene-2,6-diyl or 7,8-difluorochroman-2,6-diyl; Z 2  and Z 3  are independently a single bond, ethylene, carbonyloxy or methyleneoxy; and a is 1, 2 or 3, b is 0 or 1, and a sum of a and b is 3 or less; however, compounds represented by formula (1) are excluded from compounds represented by formula (3): wherein, in formula (1), R 1  and R 2  are independently alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons, alkenyl having 2 to 12 carbons, alkenyloxy having 2 to 12 carbons, or alkyl having 1 to 12 carbons in which at least one hydrogen is replaced by fluorine or chlorine; ring A is 1,4-cyclohexylene, 1,4-phenylene, 2-fluoro-1,4-phenylene, 2,3-difluoro-1,4-phenylene, tetrahydropyran-2,5-diyl, pyrimidine-2,5-diyl or pyridine-2,5-diyl; L 1 , L 2 , L 3  and L 4  are independently hydrogen or fluorine, in which at least three thereof is fluorine; and Z 1  is a single bond, ethylene, carbonyloxy or methyleneoxy.
