Abstract
A nematic liquid crystal composition according to the invention is used for a liquid crystal display element for an active matrix drive for TV applications or the like for which a high speed and a wide viewing angle are required. The liquid crystal composition has a negative dielectric anisotropy having a large absolute value and also has a sufficiently low viscosity. Therefore, the liquid crystal composition has excellent characteristic properties, that is, a high speed response, good display quality and a suppressed display defect, and is therefore suitable as a practical liquid crystal composition. Further, a liquid crystal display element produced using the liquid crystal composition can be used favorably as a liquid crystal display element of a VA type or the like.
