摘要： The present invention relates to liquid-crystalline media (LC media) comprising a low-molecular-weight component, a self-alignment additive comprising a thiol group and optionally a polymerizable component. The self-alignment additives 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 alignment layers. The invention discloses novel structures for self-alignment additives which have a thiol functional groups.

摘要： 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 self-alignment additives which have a certain position of the functional groups.
摘要翻译： 本发明涉及具有负或正介电各向异性的液晶介质（LC介质），其包含低分子量组分和可聚合组分。 可聚合组分包括在液晶显示器（LC显示器）的表面或单元壁处影响LC介质的垂直（垂直）对准的自对准可聚合介晶（可聚合自对准添加剂）。 因此，本发明还包括具有不具有对准层的LC介质的垂直排列的LC显示器。 本发明公开了具有官能团特定位置的自对准添加剂的新型结构。
