Liquid crystal displays homeotropic alignment

The present invention relates to liquid causing containing freely aligning additives which a homeotropic (vertical) alignment of the LC media to a surface or the cell walls of a liquid crystal display (LC-display) crystal media (LC media). The invention therefore also includes LC displays with homaotroper alignment of the liquid crystal medium (LC medium) without conventional imide orientation layers. The LC media are supplemented by a polymerizable or polymerized optional component that serves to stabilize the orientation for the adjustment of the tilt angle and / or as a passivation layer.
