Abstract: The occurrence of twist states in FLC displays can be suppressed by adding ionophores to FLC mixtures. Applicable ionophores are amides of the general formula I (I) wherein R1, R2, R3 and R4 e.g. are alkyl, cyclohexyl, phenyl or benzyl and X is alkylene with -CH2-groups being replaced by -O-, 1,2-phenylene or 1,2-cyclohexylene.

Abstract: Addition of coronands and cryptands to FLC-mixtures makes it possible to bring the FLC material into a homogeneous "bookshelf" or "quasi-bookshelf" geometry. When such a FLC mixture is used, displays which have been shock-damaged can be regenerated by applying a suitable electric field for a short period of time.
