Abstract[English]
The present invention relates to liquid-crystal media having negative dielectric anisotropy comprising a) one or more compounds of formula (I) b) one or more compounds selected from the group of the formulae (IIA), (IIB), (IIC) and (IID), and c) one or more compounds of formula (III) as defined in claim 1, and to the use of the LC media for optical, electro- optical and electronic purposes, in particular useful to enable energy-saving LC displays of the VA, IPS or FFS type.[French]
La présente invention concerne des milieux à cristaux liquides ayant une anisotropie diélectrique négative comprenant a) un ou plusieurs composés de formule (I), b) un ou plusieurs composés choisis dans le groupe des formules (IIA), (IIB), (IIC) et (IID), et c) un ou plusieurs composés de formule (III) tels que définis dans la revendication 1, et l'utilisation des milieux LC à des fins optiques, électro-optiques et électroniques, en particulier utiles pour permettre des affichages à cristaux liquides à économie d'énergie du type VA, IPS ou FFS.
