Abstract
The all solid-state ECD of the present invention features a structure composed of an oxidizable film capable of a redox reaction and showing a change in the transmittance in a certain wavelength range in the oxidized state, a reducible film capable of a redox reaction and showing a change in the transmittance in a certain wavelength range in the reduced state, an insulating film provided between said films and allowing proton conduction but prohibiting electron conduction, and a pair of electrodes between which said three films are maintained, wherein said oxidizable film is substantially composed of iridium hydroxide and/or nickel hydroxide, while said reducible film is substantially composed of tungsten oxide and/or molybdenum oxide. The ECD shows several faster response speeds, a significantly reduced voltage and the change in the transmittance improved more than six times with a drive voltage reduced to 1/8.
