Abstract

The present invention relates to an electro-optical light-modulation element of the FFS type, and to electro-optical displays and display systems, such as, for example, television screens and computer monitors, which contain elements of this type. The light-modulation elements according to the invention contain a liquid-crystalline modulation medium which has optimised elastic constants and are distinguished, in particular, by high contrast and/or optimised transmission in addition to good contrast, a low viewing-angle dependence, short response times and low addressing voltages. The present invention likewise relates to the liquid-crystalline modulation media used in the electro-optical light-modulation elements.
