DIOXANE DERIVATIVES, LIQUID-CRYSTAL COMPOSITIONS CONTAINING THE SAME, AND LIQUID-CRYSTAL DISPLAY DEVICES MADE BY USING THE SAME

摘要

Liquid-crystal compounds useful as the liquid-crystal material for low-voltage driven TFT-type liquid-crystal display devices, which exhibit a high voltage retention and a remarkably high DELTA epsilon value and are electrically and chemically stable and excellent in compatibility with existing liquid-crystal compounds; liquid-crystal compositions containing the same; and liquid-crystal display devices made by using the same. The above compounds are particular dioxane derivatives of general formula (1), and the above compositions contain at least one of the derivatives.
