Abstract
This invention provides an electrochromic device which has superior coloration repeat properties, high light transmittance and small thickness. A film is provided comprising a first electrode and second electrode in the same plane, and an electrochromic region and electrolyte region laminated in this plane. The electrochromic region is provided on the second electrode, the electrolyte region is provided on the first electrode, and the boundary between the electrochromic region and electrolyte region lies in the planar direction of the film.
Claims12
An electrochromic device, comprising:
- an insulating substrate;
- first and second electrodes installed on said substrate, each of said first and second electrodes being installed in an in-plane direction of said substrate at a given distance apart;
- an electrochromic layer installed on said substrate without being in contact with said first electrode and being in contact with said second electrode;
- an electrolyte layer installed on said substrate in contact with said first electrode;
- and
- an insulating protective layer formed on the electrochromic layer and the electrolyte layer;
- wherein a boundary between said electrochromic layer and said electrolyte layer lies on said substrate and between said first electrode and said second electrode;
- and
- wherein said insulating protective layer is installed in contact with both of said electrochromic layer and said electrolyte layer.
