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 polymerisable or polymerised 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),包括自排列介质(S
AMs),其在液晶显示器(LC显示器)的表面或单元壁上产生垂直对齐的作用。因此,本发明还包括具有液晶介质(LC介质)垂直对齐的LC显示器,而无需传统的亚酰胺对齐层。LC介质可以由可聚合或聚合组分补充,用于稳定对齐,调整倾斜角度和/或作为钝化层。
