Abstract:
The present invention relates to a liquid-crystalline medium based on a mixture of polar compounds having negative dielectric anisotropy (Δε), which is distinguished by the fact that it has a value for the ratio γ1/Δn2 in the range 6-45 with a clearing point of >60° C. and a Δε of ≤−2.3. Media of this type are particularly suitable for electro-optical displays having active-matrix addressing based on the ECB, PA LCD, FFS or IPS effect.
