Abstract
The present invention relates to liquid-crystalline media and display devices comprising polymerizable compounds, to the use of the polymerizable compounds 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 ('polymer sustained' or 'polymer sustained alignment') type. The polymerizable compounds comprise a ring system which is functionalized by three or more polymerizable groups, each connected via an optional spacer group.
