The invention relates to a liquid-crystalline medium, preferably having a nematic phase and dielectric anisotropy of 0.5 or more, which has particular dielectric properties, in that it has - either a dielectric constant perpendicular to the director (ε ⊥ ) in the range of 2 or more to less 8 or less and at the same time a ratio of the dielectric constant perpendicular to the director (ε ⊥ ) to the dielectric anisotropy (△ε), i.e. (ε ⊥ / △ε) of 1.0 or more or - or a dielectric constant perpendicular to the director (ε ⊥ ) of 8 or more and a dielectric anisotropy (△ε) of 26 or less and preferably comprises one or more compounds having a high dielectric constant perpendicular to the director (ε ⊥ ) and a high average dielectric constant (ε av. ), to the use thereof in an electro-optical display, particularly in an active-matrix display based on the IPS or FFS effect, to displays of this type which contain a liquid-crystalline medium of this type, and to the use of the compounds of formula I for improvement of the transmission and/or response times of a liquid-crystalline medium which comprises one or more additional mesogenic compounds. |
