Supertwist liquid crystal displays having outstanding properties are obtained if the nematic liquid crystal mixture is based on components selected from group A comprising compounds of the formulae IIa to IIk: ##STR1##

Supertwist liquid crystal display

Substituted phenyl trifluoromethyl ethers

The invention relates to the use of trifluorotoluene derivatives of the formula I ##STR1## in which R.sup.1 is alkyl having 1 to 12 carbon atoms in which, in addition, one or more non-neighboring CH.sub.2 groups may be replaced by --O--, --CO--, --O--CO--, --CO--O--, --O--CO--O--, --CH-halogen, --CH--CN-- and/or --CH.dbd.CH--,

Nematic liquid-crystalline phases

Trifluoromethylcyclohexane derivatives

Difluorobenzonitriles and liquid-crystalline medium

2,5-Disubstituted heterocycles of the formula I ##STR1## in which R.sup.1 and R.sup.2, each independently of one another, are alkyl, alkenyl or oxaalkyl having up to 12 C atoms,

2,5-disubstituted heterocycle and liquid-crystalline phase
