The invention relates to a liquid-crystalline medium having negative dielectric anisotropy which comprises at least one compound of the formula I in which R1, R1* and a have the meanings indicated in Claim 1, and to the use thereof for an active-matrix display, in particular based on the VA, PS-VA, PALC, FFS or IPS effect.
摘要:
The present invention relates to a liquid-crystalline medium based on a mixture of polar compounds having negative dielectric anisotropy (Δ∈), 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 Δ∈ 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.
