Publication number: 20180258346Abstract: 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.Type: ApplicationFiled: August 16, 2016Publication date: September 13, 2018Applicant: MERCK PATENT GMBHInventors: Yong-Kuk YUN, Min-Ok JIN, Hyun-Jin YOON, Mi-Nam PARK, Rocco FORTTE, Graziano ARCHETTI, Thorsten KODEK, Izumi SAITO
