Abstract
The invention provides a light modulation element comprising a flexoelectric polarisable liquid-crystalline medium, characterized in that the switching from a boundary state A to a boundary state B comprises a combination of a distinct flexoelectric switching regime and a distinct dielectric switching regime upon application of an electric field. Furthermore, the present invention relates to the use of such a light modulation element in an electro-optical device, i.e. an LCD display device, and electrooptical devices comprising the light modulation element according to the present invention. Moreover, the invention relates to a method of production of the light modulation element according to the present invention.
