摘要:
A light valve that is operable in and electrically switchable between an optically clear and transparent state and an opaque state, wherein one or more polymerisable mesogenic compounds provided in a layer containing a liquid-crystalline medium that comprises one or more mesogenic compounds, one or more chiral compounds, one or more dichroic dyes and the one or more polymerisable mesogenic compounds are subjected to photopolymerisation. Further, a liquid-crystalline medium used in the method, a light valve obtained or respectively obtainable by carrying out the method, and the use of the light valve in mobile devices.
