Abstract
Liquid-crystalline media containing one or more mesogenic compounds, one or more chiral compounds, and one or more polymerizable mesogenic compounds, wherein the media exhibit a pitch of 0.55 μm or more and a clearing point of 80° C. or more and wherein the one or more polymerizable mesogenic compounds are contained in an amount, based on the overall contents of the media, of 5% by weight or less, are suitable as modulation materials. Such modulation materials can be used in switching layers and window elements.
