Abstract: Liquid-crystalline media (LC media) comprising self-aligning mesogens (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 self-alignment additives contain five-ring systems. LC displays having homeotropic alignment of the liquid-crystalline medium (LC medium) without conventional alignment layers are provided.

Abstract: Disclosed are liquid-crystalline media (LC media) comprising a low-molecular-weight component and a polymerisable component. The polymerisable component contains self-aligning, polymerisable mesogens (polymerisable 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). Disclosed are also LC displays having homeotropic alignment of the LC medium without alignment layers. Further disclosed are the structures for polymerisable self-alignment additives.
