Title
(EN) LIQUID CRYSTAL MEDIUM
(FR) MILIEU À CRISTAUX LIQUIDES
Abstract
(EN) The present invention relates to a liquid crystal (LC) medium comprising a compound of formula I and one or more compounds selected from the group of compounds of the formulae IIA, IIB, IIC and IID, IIA IIB IIC IID as defined in claim 1, and to the use thereof for optical, electro-optical and electronic purposes, in particular in LC displays, especially in IPS, FFS, VA or PS-VA displays.
(FR) La présente invention concerne un milieu à cristaux liquides (CL) comprenant un composé de formule I et un ou plusieurs composés choisis dans le groupe des composés représentés par les formules IIA, IIB, IIC et IID, telles que définies dans la revendication 1, et leur utilisation pour des applications optiques, électro-optiques et électroniques, en particulier dans des écrans à cristaux liquides, notamment dans des écrans IPS, FFS, VA ou PS-VA.
