An electro-optical device containing an electrochromic material layer and electrolytic solution interposed between mutually opposed base plates, each having an electrode on the surface thereof, wherein said electrolytic solution consists essentially of (a) an iodide source material as a redox reaction promoter selected from the group consisting of metal iodides and ammonium iodides, and (b) a lactone solvent capable of dissolving the redox reaction promoter, with the proviso that when the iodide ion source material is not also a metal cation source, a cation source material capable of generating H.sup.+ or Li.sup.+ is further added.
