Abstract

The present invention relates to polymerizable compounds, to processes and intermediates for the preparation thereof, to the use thereof for optical, electro-optical and electronic purposes, in particular in liquid-crystal (LC) media and LC displays having a polymer-stabilized blue phase, and in LC media for LC displays of the PS or PSA type (“polymer sustained” or “polymer sustained alignment”), and to LC media and LC displays comprising these compounds.
