LIQUID CRYSTAL COMPOUNDS EXHIBITING NEGATIVE ANISOTROPY OF PERMITTIVITY, LIQUID CRYSTAL COMPOSITIONS, AND LIQUID CRYSTAL DISPLAYS

摘要

Liquid crystal compounds which exhibit not only a negative anisotropy of permittivity but also extremely high voltage retention and low threshold voltages, are reduced in the temperature dependence of these properties, difficultly exhibit a smectic phase, and are excellent in compatibility with other liquid crystal materials; liquid crystal compositions containing the same; and liquid crystal displays made by using the compositions. The compounds are represented by general formula (1).
