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.
