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: A liquid-crystal mixture comprising at least two components and containing, as one component, a macrocyclic compound of the formula (1) … … where a, b, c, d, e and f, independently of one another, are an integer from zero to 4, where a+b+c+d+e+f is >/= 7, and -A-, -B-, -C-, -D-, -E- and -F- are identical or different and are, for example, -CH2-, -CH=CH-, -CO- or -COO-,… results, in FLC displays, in the formation of uniform alignment and in the avoidance of twist states, which is expressed in significantly improved contrast.

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.

Abstract: The use of alignment layers containing compounds having an amphiphilising effect increases the contrast and/or brightness of the image in the FLC display.
