The present invention relates to liquid-crystalline media (LC media) having negative or positive dielectric anisotropy comprising self-alignment additives (SAMs) with an at least one bifunctional or polyfunctional anchor group, which effects the 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 stabilisation of the alignment, for adjustment of the tilt angle and/or as passivation layer.
本发明涉及具有负或正电介质各向异性的液晶介质(LC介质),其中包含至少一个双功能或多功能锚定基团的自组装添加剂(SAMs),其在液晶显示器(LC显示器)表面或单元壁上产生同向(垂直)排列的作用。因此,本发明还包括具有同向排列的液晶介质(LC介质)的LC显示器,而无需传统的亚酰胺排列层。LC介质可以通过可聚合或聚合的组分来补充,该组分用于稳定排列,调整倾斜角度和/或作为钝化层。
