Abstract

The present invention relates to mesogenic media and to electro-optical displays comprising these media as light modulation media. In particular, the electro-optical displays according to the present invention are displays, which are operated at a temperature, at which the mesogenic modulation media are in an optically isotropic phase, preferably in a blue phase.
