摘要： Provided are a liquid crystal composition having negative dielectric anisotropy and a liquid crystal display device that uses the liquid crystal composition. The present invention relates to a liquid crystal composition having a negative dielectric anisotropy (Δ∈) and useful as an electro-optic liquid crystal display material, and a liquid crystal display device that uses the liquid crystal composition. The liquid crystal composition contains one or more compounds represented by general formula (I) and one or more compounds represented by general formula (II). Since the rate of change in operation voltage versus temperature can be decreased by using the liquid crystal composition of the present invention, the invention is effective for improving the display quality in a low-temperature zone. Thus, the liquid crystal composition is suitable for use in vehicle-mounted displays and mobile appliances that are expected to be used in cold areas and outdoors.
