Abstract:
The invention is directed to liquid crystal compositions for use in bistable liquid crystal devices and to bistable liquid crystal devices containing said liquid crystal compositions. The liquid crystal composition comprises a component (π) said component (π) containing one or more compounds having a phenyl ring of formula A Whereby XA is F, CI, SF5, NCS or a C1 to C8 alkanyl, alkenyl or alkoxy radical substituted with at least one F atom; and LA is H or F.
