Patent ID: 6896939

Claim:
A nematic liquid-crystal medium, wherein said medium comprises a) a dielectrically negative liquid-crystalline component, component A, which comprises one or more dielectrically negative compound(s) of the formula I in which R 11 and R 12 are each, independently of one another, alkyl having from 1 to 7 carbon atoms, alkoxy having from 1 to 7 carbon atoms or alkoxyalkyl, alkenyl or alkenyloxy having from 2 to 7 carbon atoms, one of Z 11 and Z 12 are each, independently of one another, —CH 2 —CH 2 —, —CH 2 —CF 2 —, —CF 2 —CH 2 —, —OCH 2 —, —CH 2 O—, —OCF 2 —, —CF 2 O— or a single bond, and n is 1, where one or more H atoms in the third phenyl ring may optionally be replaced by F atoms if and b) a further dielectrically negative liquid-crystalline component, component B, which is different from component A.
