Abstract
Official abstract text for this publication.
The invention relates to a liquid-crystalline medium based on a mixture of polar compounds having negative dielectric anisotropy, which contains at least one compound of the formula I and at least one compound of the formula II in which R 1 , R 2 , R 3 , R 4 , ring A, Z 1 , Z 2 and m are as defined in Claim 1, and to the use thereof for an active-matrix display based on the ECB, VA, PS-VA, FFS, PALC or IPS effect.
First claim
Opening claim text (preview).
The invention claimed is: 1. A liquid crystalline medium containing at least one compound of formula I, and at least one compound of formula CCPC-n-m, CCOC-n-m and CH-nm, and at least one compound of formula II wherein R 1 to R 2 are each independently alkyl or alkoxy with 1 to 8 C atoms, wherein one or more CH 2 -groups are optionally replaced by —CH═CH—, —CF 2…
