A liquid crystal composition is provided that has a wide temperature range of a nematic phase, a small viscosity, a suitable optical anisotropy, a large negative dielectric anisotropy and a large specific resistance, and a liquid crystal composition is provided that satisfies these characteristics and also has a low minimum temperature of a nematic phase, preferably -20 DEG C or less. A liquid crystal display device containing the liquid crystal composition is also provided. The liquid crystal composition has a negative dielectric anisotropy and contains a liquid crystal compound having an ethylene bond and 2,3-difluorophenylene as a first component and a liquid crystal compound having phenylene having halogens replacing two hydrogens as the second component, and the liquid crystal display device contains the liquid crystal composition. |
