Title
(EN) LIQUID CRYSTAL MEDIA COMPRISING POLYMERISABLE COMPOUNDS
(FR) MILIEUX CRISTAUX LIQUIDES COMPRENANT DES COMPOSÉS POLYMÉRISABLES
Abstract
(EN)
The present invention relates to liquid crystal (LC) media comprising one or more polymerisable compounds as further specified in the description or claims and a self-alignment additive for vertical alignment. The media are adapted for use in LC displays, especially in LC displays of the polymer-sustained alignment type.
(FR)
La présente invention concerne des milieux cristaux liquides (LC) comprenant un ou plusieurs composés polymérisables tels que décrits dans la description ou les revendications et un additif d'auto-alignement pour l'alignement vertical. Les milieux sont conçus pour être utilisés dans des écrans à cristaux liquides, en particulier dans des écrans à cristaux liquides du type à alignement aidé par les polymères.
