ABSTRACT:
An electro-optical device having an oxidatively coloring electrochromic layer of composition Mn.sub.x V.sub.y O.sub.z, where 0.05 x/y<1, x+2y<z<2x+(5/2)y, and x+y=1, with improved transmittance modulation, the Mn.sub.x V.sub.y O.sub.z providing complementary optical modulation to reductively coloring electrochromic materials in devices employing an all-thin-film configuration with a solid ion conducting electrolyte and in devices employing a laminated configuration with a polymeric ion conducting electrolyte.
