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: Compounds of the formula I, liquid-crystalline media which contain at least one compound of the formula I and electro-optical displays which contain the LC mixtures, especially for the self-aligning VA, PSA, PS-VA, PVA, MVA, PM-VA, HT-VA or VA-IPS mode in which R1, R2, ring A1, Z1, Z2, Sp, P, L1, L2, r1, r2, r3, m, n, p1 and p2 have the meanings indicated above.

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 meso-gens (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.
