Die vorliegende Erfindung betrifft flüssigkristalline Medien (FK-Medien) enthaltend selbst-ausrichtende Mesogene (Selbstorientierungsadditive), die eine homöotrope (vertikale) Ausrichtung der FK-Medien an einer Oberfläche oder den Zellwänden einer Flüssigkristallanzeige (FK-Anzeige) bewirken. Die neuen Selbstorientierungsadditive besitzen Fünfringsysteme. Die Erfindung umfasst auch FK-Anzeigen mit homöotroper Ausrichtung des flüssigkristallinen Mediums (FK-Mediums) ohne konventionelle Orientierungsschichten.
本发明涉及含有自定向介质(自定向添加剂)的液晶介质(FK 介质),该介质可使液晶显示器(FK 显示器)表面或细胞壁上的 FK 介质产生同向(垂直)定向。新型自定向添加剂具有五环系统。本发明还包括液晶介质(FK 介质)具有各向同性取向的 FK 显示器,而没有传统的取向层。

The present invention relates to liquid crystal (LC) media comprising several polymerizable compounds and an additive for vertical alignment as further specified in the description or claims. The media are adapted for use in LC displays, especially in LC displays of the polymer-sustained alignment type while omitting one or both of the conventional alignment layers.

Disclosed are liquid-crystalline media (LC media) comprising a low-molecular-weight component and a polymerisable component. The polymerisable component contains self-aligning, polymerisable mesogens (polymerisable self-alignment additives) which effect homeotropic (vertical) alignment of the LC media at a surface or the cell walls of a liquid-crystal display (LC display). Disclosed are also LC displays having homeotropic alignment of the LC medium without alignment layers. Further disclosed are the structures for polymerisable self-alignment additives.
