发明名称 Compound, liquid crystal composition and liquid crystal display device
摘要 A liquid crystal composition is described, which has a nematic phase and contains a compound having a high maximum temperature and a large dielectric anisotropy as a first component, and a specific compound having a large dielectric anisotropy as a second component, and may also contain a specific compound having a large dielectric anisotropy as a third component, and a compound having a small viscosity as a fourth component. An AM liquid crystal display device including the composition is also described.

主权项 1. 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, in which a proportion of the first component is in a range of 25 wt % to 85 wt % based on a total weight of the liquid crystal composition: wherein R1 and R2 are independently alkyl having 1 to 12 carbons, alkoxy having 1 to 12 carbons, or alkenyl having 2 to 12 carbons; ring A, ring B and ring C are independently 1,4-cyclohexylene, 1,4-phenylene, 2-fluoro-1,4-phenylene, 3-fluoro-1,4-phenylene, 3,5-difluoro-1,4-phenylene, pyrimidine-2,5-diyl, 2,6,7-trioxabicyclo[2.2.2]octane-1,4-diyl or tetrahydropyran-2,5-diyl; X1 and X2 are independently hydrogen or fluorine; Y1 and Y2 are independently fluorine, chlorine, trifluoromethyl or trifluoromethoxy; Z1, Z2, Z3 and Z4 are independently a single bond, ethylene, carbonyloxy or difluoromethyleneoxy; m and n are 0, 1, 2 or 3, and a sum of m and n is 2 or 3; and p is 1, 2, 3 or 4.
