Liquid crystal medium and light modulation element

Abstract

The invention relates to a liquid crystal medium comprising one or more dielectrically negative compounds and one or more dielectrically positive compounds, characterized in that the medium as a whole exhibits a dielectrically anisotropy (Δε) in the range from −0.25 to +0.25. Furthermore, the invention relates to a method of production of such medium and to the use of such medium in a light modulation element utilizing flexoelectric switching. Moreover, the invention relates to a light modulation element utilizing flexoelectric switching comprising the described medium, to a method of production of such light modulation element, to the use of such light modulation element in electro-optical devices and to these electro-optical devices as such.
