Patent ID: 8221854

Claim:
A liquid-crystal medium, comprising: a dielectrically positive component, component A, comprising one or more dielectrically positive compounds selected from the group of the compounds of the formulae I′A-1, I′A-2, I″A-1, I″A-2, I′″A-1 and I′″A-2: in which R 1 denotes alkyl, alkoxy, fluorinated alkyl or fluorinated alkoxy having 1 to 7 C atoms, alkenyl, alkenyloxy, alkoxyalkyl or fluorinated alkenyl having 2 to 7 C atoms, X 1 denotes —CN, halogen, halogenated alkyl or halogenated alkoxy having 1 to 3 C atoms or halogenated alkenyl or halogenated alkenyloxy having 2 or 3 C atoms, and L 11 to L 16 , independently of one another, denote H or F; and comprising a dielectrically neutral component, component D, comprising one or more dielectrically neutral compounds of the formula VI in which R 61 and R 62 , independently of one another, have the meaning indicated for R 1 under formula I, and if it occurs twice, independently of one another on each occurrence, denotes Z 61 and Z 62 , independently of one another and, if Z 61 is present twice, also these independently of one another, denote —CH 2 CH 2 —, —COO—, trans-CH═CH—, trans-CF═CF—, —CH 2 O— —CF 2 O— or a single bond, and r denotes 1 or 2.
