Supertwist liquid-crystal displays (SLCDs) with outstanding properties are obtained if the nematic liquid-crystal mixtures used therein comprise at least one compound selected from the formulae 1A and 1B and at least one compound of the formula 1C in which Ra is alkyl, alkoxy, alkenyl or alkenyloxy having 1 to 12 carbon atoms, Rb is alkyl or alkoxy having 1 to 5 carbon atoms, Z is -COO-, -CH2CH2- or a single bond, and La, Lb, Lc, Ld, Le, Lf, Lg, and Lh in each case independently of one another are H or F, with the proviso that the 1,4-phenylene rings carry not more than 2 fluorine atoms per ring, R3 is an alkenyl group having 2 to 7 carbon atoms, R4 is Ra or R3 and c is 0 or 1. |
