摘要: A liquid-crystalline mixture comprising two or more compounds of the general formula I, ##STR1## in which R.sup.1 is straight-chain alkyl having 3, 5 or 7 carbon atoms, three or more compounds of the general formula II, ##STR2## in which R.sup.2 is straight-chain alkyl having 2 to 7 carbon atoms, three or more compounds of the general formula III, ##STR3## in which R.sup.3 and R.sup.4 are each independently alkyl or alkoxy with 1 to 10 carbon atoms, and two or more compounds of the general formula IV, ##STR4## in which R.sup.5 and R.sup.6 are each independently have one of the meanings indicated for R.sup.3 and m is 0 or 1. A "multibottle-system" comprising said mixture and an electrooptical display device based on the principle of the twisted nematic cell.
