Optisch aktive Verbindung und antiferroelektrische Flüssigkristallzusammensetzung |
摘要 |
<p>Disclosed is a novel optically active compound which exhibits an antiferroelectric liquid crystal phase and has a low threshold voltage and a low viscosity, a novel optically active compound which doesn't exhibit an antiferroelectric liquid crystal phase but can be incorporated in an antiferroelectric liquid crystal having a high threshold voltage to reduce the threshold voltage thereof, an antiferroelectric liquid crystal composition containing the compound, and a process for the reduction of the threshold voltage of an antiferroelectric liquid crystal composition.</p> |
