Abstract
A liquid crystal composition of the present invention is used for a liquid crystal display device of an active matrix driving mode which is required to have fast response. The liquid crystal composition has negative dielectric anisotropy, a large absolute value thereof, and low viscosity. Also, the liquid crystal composition has excellent liquid crystallinity that does not decrease Δn and Tni, and the like, and exhibits a stable liquid crystal phase within a wide temperature range. Further, the liquid crystal composition is chemically stable to heat, light, water, and the like and is thus suitable for use in a liquid crystal display device in which display defects are suppressed in large-size application requiring high reliability. A liquid crystal display device using the liquid crystal composition can be suitably used as a liquid crystal display device of a VA mode or the like.
