  The present invention relates to polymerisable compounds, to processes and intermediates for the preparation thereof, to liquid-crystal (LC) media comprising them, and to the use of the polymerisable compounds and LC media for optical, electro-optical and electronic purposes, in particular in LC displays, especially in LC displays of the polymer sustained alignment (PS, PSA) and self-aligning (SA) type.

  本发明涉及可聚合化合物，用于其制备的工艺和中间体，包括它们的液晶（LC）介质，以及可聚合化合物和LC介质在光学、电光和电子用途中的使用，特别是在LC显示器中，尤其是在聚合物维持定向（PS，PSA）和自对准（SA）类型的LC显示器中的使用。

  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。

  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.

  本发明涉及具有正或负介电各向异性的液晶介质（LC介质），包括低分子量成分和可聚合成分。可聚合成分包括自排列、可聚合的介质基（可聚合自排列添加剂），可在液晶显示器（LC显示器）的表面或细胞壁处实现LC介质的同向（垂直）排列。因此，本发明还包括具有同向排列的LC介质的LC显示器，而无需排列层。本发明还揭示了自排列添加剂的新结构，其具有某些功能基团的位置。
