Ferroelectric liquid crystal device containing optically active azo or
azoxy benzene type mesomorphic compound with extended life
摘要:
A ferroelectric liquid crystal composition containing an optically active mesomorphic compound represented by the following formula (I) or (II): ##STR1## wherein R.sub.1 and R.sub.2 are respectively an alkyl, and C with * represents an asymmetric carbon atom. The mesomorphic compound provides the ferroelectric liquid crystal composition with an extended operational life in a liquid crystal device.
