3--6- -2- 3-aryl-6-substituted cyclohex-2-enones liquid crystal composition comprising the same and liquid crystal display device using the liquid crystal composition

摘要

The present invention relates to a liquid crystal display device using the liquid crystal composition and a liquid crystal composition comprising this 3-aryl-6-substituted cycloalkyl-2-enone. 3-aryl-6-substituted cycloalkyl-2-enone represented as one of the above Chemical Formulas 1 to 11 are excellent in chemical stability as the material, its application range is extensive. In particular, the material has a nematic liquid crystal properties, can be used as an intermediate in a polar liquid crystal compound. And a liquid crystal composition containing such liquid crystal compound has a nematic phase in a wide temperature range. With Using this liquid crystal composition can be obtained a liquid crystal display device having an optical anisotropy, the response speed and the driving voltage characteristic improved.
