Abstract

The present invention relates to a mixture comprising a not fully aromatic polymerisable compound and a polymerisable photoinitiator, to liquid-crystal (LC) media comprising them, and to the use of the polymerisable compounds and LC media for optical, electro-optical and electronic purposes, in particular in LC displays, especially in LC displays of the polymer sustained alignment type.
