Abstract
The present invention relates to an assembly of switching layers for dimming and scattering of light and to window elements comprising the arrangement of switching layers.
Claims18
A multilayer arrangement for regulating the passage of light, which comprises
- a first switching layer which is switchable between an optically clear state and a light scattering state and which contains a material which comprises a liquid-crystalline medium comprising one or more mesogenic compounds and one or more chiral compounds, and a polymeric component, wherein the polymeric component is contained in the material in an amount, based on the overall contents of the material, of 5% by weight or less, and
- a switching element comprising a second switching layer, wherein the switching element is switchable between a bright state and a dark state and wherein the second switching layer is a liquid-crystalline layer.
