CYCLOHEXANE DERIVATIVES, LIQUID-CRYSTAL COMPOSITION, AND LIQUID-CRYSTAL DISPLAY ELEMENT

摘要

Novel liquid crystalline compounds which have a wide temperature range of liquid crystal phase, are excellent in miscibility with other liquid crystalline compounds, have a low viscosity, are low in toxicity, and are safe; liquid crystal compositions comprising the liquid crystalline compound; and liquid crystal display devices fabricated by using the composition are provided; and the compounds are cyclohexane derivatives expressed by the general formula (1) wherein R represents an alkylene chain having 2 to 10 carbon atoms in which alkylene chain ethylene group (-CH2CH2-) may be replaced by ethenylene group (-CH=CH-) or methylenoxy group (-OCH2-); and M represents COOH or CN group.
