NEMATIC LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE UTILIZING THE SAME

摘要

The present invention relates to a nematic liquid crystal composition that exhibits a positive dielectric anisotropy (”µ), the liquid crystal composition being useful as a liquid crystal display material, and a liquid crystal display element using the same. The liquid crystal composition of the present invention has a large absolute value of dielectric anisotropy thereof and a low viscosity. By using this liquid crystal composition, it is possible to provide a liquid crystal display element which has a high contrast, high-speed responsiveness, and good display quality in which image sticking and display defects are not generated. The liquid crystal display element using the liquid crystal composition of the present invention is a useful display element which realizes both high-speed response and suppression of display defects. In particular, the liquid crystal display element is useful as a liquid crystal display element for active-matrix driving, and can be applied to, for example, an IPS-type or TN-type liquid crystal display element.
