Liquid crystal characteristic chemical compound, the liquid crystal composition which includes this, the liquid crystal element which possesses that, method of presentation, and the display null which use

摘要

A mesomorphic compound of the formula (I) and an optically active compound of formula (II) are suitable as a component for a liquid crystal composition providing improved response characteristics and having an improved helical pitch at a cholesteric phase or a chiral smectic C phase. The above liquid crystal composition is useful as an element of a liquid crystal device providing a good display characteristics including a gradation display. CHEM IMAGE
