The present invention relates to a liquid crystal medium which preferably has a nematic phase and a dielectric anisotropy of 0.5 or higher, the liquid crystal medium having a specific dielectric property because it has - at 2 or higher to less than 8 or The dielectric constant (ε⊥ perpendicular to the director) perpendicular to the director's dielectric constant (ε⊥) in the lower range and having 1.0 or higher at the same time and the dielectric anisotropy (Δε) The ratio, that is, (ε⊥/Δε), or - or 8 or higher, perpendicular to the dielectric constant of the director (ε⊥) and dielectric anisotropy (Δε) of 26 or lower, and Preferably, it comprises one or more compounds having a higher dielectric constant (ε⊥) perpendicular to the director and a higher average dielectric constant (εav.), which is used in electro-optic displays, in particular, For active matrix displays based on IPS or FFS effects; displays of this type containing such liquid crystal media; and uses of the compounds of formula I for improving liquid crystal media comprising one or more additional liquid crystal primordial compounds Transmittance and / or reaction time. |
