More Information
Summary:The invention relates to a liquid-crystalline medium which comprises at least one compound of the formula IA, in which Z1 denotes a single bond, -CH2CH2-, -CH=CH-, -CH2O-, -OCH2-, -CF2O-, -OCF2-, -COO-, -OCO-, -C2F4-, -C ≡ C-, -CF=CF-, -CH=CHCHO- or -CH2CF2O-, and in addition at least one compound of the formula CC-n-V and/or the compound of the formula CC-V-V1, where n denotes 2, 3, 4, 5 or 6, with the provisos that - the percentage proportion of the compound(s) of the formula IA is greater than or equal to the percentage proportion of CC-n-V, and/or -- the percentage proportion of the compound(s) of the formula IA is greater than the percentage proportion of CC-V-V1, where the percentage proportion is based on the liquid-crystalline medium, and to the use thereof for an active-matrix display, in particular based on the VA, PSA, PVA, PS-VA, SS-VA, SA-VA, PA-VA, PALC, FFS, PS-FFS, PS-IPS or IPS effect.
