Supertwist liquid crystal display

Supertwist liquid crystal displays having very short switching times are obtained if the nematic liquid crystal mixture contains at least one component chosen from group A consisting of compounds of the formulae AI to AVI: ##STR1## wherein R.sup.1 and R.sup.2 in each case independently of one another are each R and R is alkyl having 1-12 C atoms, wherein one or two non-adjacent CH.sub.2 groups can also be replaced by --O--, --CH.dbd.CH--, --CO--, --O--CO-- or --CO--O--, and up to four other components.

Biphenylylethanes of the formula I ##STR1## in which one of the radicals R.sup.1 and R.sup.2 is X and the other radical R.sup.1 or R.sup.2 is R--Y-- where
