摘要： A liquid-crystalline media (LC media) containing a low-molecular-weight, non-polymer component, and a combination of self-alignment additives for vertical alignment of two or more of the specified kinds (formulae IA to IM). The combination of two or more self-alignment additives affect homeotropic (vertical) alignment of the LC media at a surface or the cell surfaces of a liquid-crystal display (LC display).
