The present invention relates to an electro-optical light modulation element and to electro-optical displays and display systems, such as television screens and computer monitors, containing elements of this type. The light modulation elements according to the invention contain a mesogenic modulation medium which is in the isotropic phase during operation of the light modulation elements and are particularly distinguished by very short response times in addition to good contrast and low viewing-angle dependence. The mesogenic modulation media used in the electro-optical light modulation elements are likewise a subject-matter of the present invention.
