The present invention relates to liquid-crystalline media (LC media) having negative or positive dielectric anisotropy, comprising a low-molecular-weight component and a polymerizable component. The polymerizable component comprises self-aligning, polymerizable mesogens (polymerizable 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). The invention therefore also encompasses LC displays having homeotropic alignment of the LC medium without alignment layers. The invention discloses novel structures for polymerizable self-alignment additives which have a certain position of the functional groups.
本发明涉及具有负或正介电常数各向异性的液晶介质,包括低分子量组分和可聚合组分。可聚合成分包括可聚合的自对准中间体(可聚合的自对准添加剂),可使液晶介质在液晶显示器(LC 显示器)的表面或单元壁上实现各向同性(垂直)对准。因此,本发明也包括液晶显示屏,其液晶介质具有各向同性对准功能,无需对准层。本发明公开了可聚合自对准添加剂的新型结构,其官能团具有一定的位置。
