    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 1 wherein R1 and R2 are independently of each other an alkyl, alkoxy or alkenyl group with 1 to 12 C atoms, it also being possible for one or more CH2 groups in these radicals to be replaced, in each case independently of one another, by nullOnull, nullCHnullCHnull, nullCOnull, nullOCOnull or nullCOOnull in such a manner that oxygen atoms are not linked directly to one another, Z is OCH2 or CH2O, and m is 0 or 1.
