FERROELECTRIC LIQUID-CRYSTAL MIXTURES CONTAINING CHIRAL PYRANOSE COMPOUNDS FOR RESPONSE-VOLTAGE MINIMUM MODE

Ferroelectric liquid crystal (FLC) materials for the response-voltage minimum (tau-V(min)) mode were developed by doping novel chiral pyrano se compounds into achiral host materials with negative dielectric anis otropy. The chiral pyranose derivatives, wherein three chiral centers and a trifluoromethyl group were fixed in the 6-membered ring, induced short tau(min) in the tau-V(min) characteristic. The developed FLC ma terials were driven by drive schemes for the tau-V(min) mode, giving s hort line address times.
