LIQUID CRYSTAL COMPOUND, FERROELECTRIC LIQUID CRYSTAL COMPOSITION, AND FERROELECTRIC LIQUID CRYSTAL DISPLAY

摘要

A liquid crystal compound represented by the following formula is provided to enhance the contrast of a liquid crystal device using ferroeloctric liquid crystal: R¹ is an alkyl group having 4 to 6 carbon atoms. R² is an alkyl group having 6 to 18 carbon atoms or an alkoxy group having 6 to 18 carbon atoms. X¹ and X² are each independently hydrogen ox fluorine.
