Abstract
An electro-optical device, such as a light valve, has a cell formed of opposed cell walls, a light-modulating unit comprising a suspension containing anisometric particles suspended in a liquid suspending medium between the cell walls, and opposed electrodes operatively associated with the cell walls for applying an electrical field across the suspension, the anisometrically shaped particles having an average particle size of about 0.1 microns or less.
