The present invention relates to liquid-crystalline media (LC media) having negative or positive dielectric anisotropy comprising self-aligning mesogens (SAMs) which effect homeotropic (vertical) alignment of the LC media at a surface or the cell walls of a liquid-crystal display (LC display). The invention therefore also encompasses LC displays having homeotropic alignment of the liquid-crystalline medium (LC medium) without conventional imide alignment layers. The LC media may be supplemented by a polymerizable or polymerized component, which serves for stabilization of the alignment, for adjustment of the tilt angle and/or as passivation layer.
本发明涉及具有负或正介电各向异性的液晶介质(LC 介质),该介质包含自配位介质(SAM),可在液晶显示器(LC 显示器)的表面或细胞壁上实现液晶介质的各向同性(垂直)配位。因此,本发明还包括液晶显示屏,其液晶介质(LC 介质)具有各向同性排列,而无需传统的酰亚胺排列层。液晶介质可添加可聚合或聚合成分,用于稳定配向、调整倾斜角度和/或作为钝化层。
