The invention relates to a polymerisable LC medium with flat optical dispersion, a polymer film with flat optical dispersion obtainable from such a medium, and the use of the polymerisable LC medium and polymer film in optical, electro optical, electronic, semiconducting or luminescent components or devices.

Polymerisable LC medium and polymer film with flat optical dispersion

The present invention relates to a process of preparing a light modulation element of the PS-ULH (polymer stabilised ULH) type, which allows to reduce the operational voltage and allows to improve the switching time of the light modulation element.

Process of preparing a light modulation element

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.
