Disclosure of the Invention A problem to be solved by the present invention is to provide a liquid crystal composition suppressing deterioration of viscosity (viscosity) accompanied by increase in DELTA n and increase in DELTA epsilon and provision of a liquid crystal display element in which the response speed is remarkably improved by using the liquid crystal composition . The liquid crystal composition of the present invention is characterized in that? N is large, ?? is negative, and its absolute value is large. It also exhibits a liquid crystal phase (liquid crystal phase) having a low η, excellent liquid crystallinity and stable over a wide temperature range. Further, the liquid crystal composition is chemically stable with respect to heat, light, water and the like, and therefore is a practical liquid crystal composition which can be driven at a low voltage and is highly reliable. |
