Liquid crystalline compounds having a 1.1.1 pentane bicyclo structure, the liquid crystal display device and liquid crystal composition

摘要

The purpose of the present invention is to provide a new liquid crystal compound which is suitable for a TFT display system, an STN display method and a liquid crystal display composition for a TN display method, and a liquid crystal compound which expresses various properties suitable for compatibility with a low temperature at a low temperature, and selects a substituent for various display systems It is to provide a liquid crystal compound capable of low voltage driving or high-speed response and to construct a highly reliable liquid crystal composition, a liquid crystal composition containing the liquid crystal composition, and a liquid crystal display device using the liquid crystal composition. General formula (1)A liquid crystalline compound containing a bicyclo [1.1.1] pentane structure represented by a liquid crystal composition containing the liquid crystalline compound, and a liquid crystal display device using the liquid crystal composition.
