Abstract:
Compounds of the formula I
in which
R1 is alkyl or alkoxy in which CH2 groups are optionally replaced, and X1 is alkyl OCF3, CF3, CHF2, OCF2CF3, CCF2CHFCF3, OCF═CF2, OCH═CF2 or F,
a liquid-crystalline medium containing a compound of formula I,
and use thereof in electro-optical liquid-crystal displays, in particular in TN, STN, TN-TFT, OCB, IPS, PS-IPS, FFS, HB-FFS or PS-FFS-, positive VA displays and in shutter spectacles for 3D effects and LC lenses.
