An electro-optical device including a cell formed of opposed cell walls, a light modulating unit comprising a suspension containing anisometrically-shaped particles formed of a heat-reflective mixed metal oxide, e.g., bismuth manganese oxide, 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, wherein the particles have an average length in a range between about 1 micron and about 50 nanometers.
