摘要:
The invention relates to a liquid-crystalline medium based on a mixture of polar compounds having negative dielectric anisotropy, which contains at least one compound of formula I ##STR1## and at least one compound of formula II ##STR2## wherein R.sup.1 is alkyl or alkoxy with 1 to 8 C atoms or alkenyl with 2 to 7 C atoms,R.sup.2 is alkenyl with 2 to 7 C atoms,R.sup.3 and R.sup.4 are each independently alkyl or alkoxy with 1 to 8 C atoms, ##STR3## m is 0 or 1.
