  In a process for the purification of a liquid-crystal mixture ( 7 ), the liquid-crystal mixture ( 7 ) is passed through a first electrodialysis cell ( 2 ) and a concentrate solution ( 14 ) is passed through a second electrodialysis cell ( 8 ) which is adjacent to the first electrodialysis cell ( 2 ) and is separated by an ion-exchanger membrane ( 9 ), and an electric field transverse to a direction of passage of the liquid-crystal mixture ( 7 ) through the first electrodialysis cell ( 2 ) is generated with the aid of an anode/cathode arrangement ( 15, 16 ) arranged outside the electrodialysis cells ( 2, 8 ) so that ionised constituents of the liquid-crystal mixture ( 7 ) are discharged at the ion-exchanger membrane ( 9 ) and removed from the liquid-crystal mixture ( 7 ).

  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.
