ABSTRACT:
An optically active compound represented by a formula (I) characterized by containing an oxazolidinone-3,5-diyl skeleton directly connected to cyclic groups in 3 and 5 positions is suitable as a component for a liquid crystal composition providing improved response characteristics and a high contrast. A liquid crystal device is constituted by disposing the liquid crystal composition between a pair of electrode plates. The liquid crystal device may preferably be used as a display panel constituting a liquid crystal apparatus providing good display characteristics.
