Abstract:
A liquid-crystalline medium which comprises at least one compound selected from the group of compounds of the formulae IA to IH,
in which
Z1 denotes a single bond, —CH2CH2—, —CH═CH—, —CH2O—, —OCH2—, —CF2O—, —OCF2—, —COO—, —OCO—, —C2F4—, —(CH2)4—, —CHFCHF—, —CF2CH2—, —CH2CF2—, —C≡C—, —CF═CF—, —CH═CHCHO— or —CH2CF2O—,
and the use thereof for an active-matrix display, in particular based on the VA, PSA, PS-VA, PALC, FFS, PS-FFS, SA-VA, PS-IPS or IPS effect.
