Patent number: 10294426Abstract: 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.Type: GrantFiled: June 25, 2015Date of Patent: May 21, 2019Assignee: MERCK PATENT GMBHInventors: Graziano Archetti, Izumi Saito, Rocco Fortte, Oliver Heppert, Andreas Taugerbeck, Elena Neumann
