摘要： The object of the present invention is to provide a ferroelectric liquid crystal mixture having a negative value of Δε and allowing a high speed response and a low voltage driving, as well as a liquid crystal display device using the liquid crystal mixture of the invention. The ferroelectric liquid crystal mixture according to the invention comprises two or more compounds from at least two different of the following classes of compounds: A. thiadiazoles, B. phenanthrenes, C. 2-fluoropyridines, D. difluorobenzenes, E. meta-substituted aromatic compounds.
