Compounds which have a chiral, orthogonal, higher-order smectic phase, in particular a S<*>B or a S<*>E phase can be used in the region of this phase or phases as a display or switching medium in electro- optical display elements or switching elements which are based on the utilisation of the electrokinetic effect.
