    摘要: Supertwist liquid-crystal displays (SLCDs) with outstanding properties are obtained if the nematic liquid-crystal mixtures used therein comprise one or more compounds of the formula IA and one or more compounds of the formula IB 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  are each, independently of one another,  and one of the rings  may alternatively be R3 is an alkenyl group having 2 to 7 carbon atoms, R4 is as defined for Ra in the formula IA, and c is 0 or 1.
