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 of formula (II) 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 de formule (II) tels que définis dans la revendication 1, ainsi que leur utilisation à des fins optiques, électro-optiques et électroniques, en particulier dans des écrans à cristaux liquides, en particulier dans des écrans IPS, FFS, VA ou PS-VA.
