Electrochromic device
First Claim
1. An electrochromic device comprising:
- a pair of electrically conductive counter plates;
an ion conductive material placed between said electrically conductive counter plates;
a layer containing an electrochromic material provided in at least one of locations between said ion conductive material and the electrically conductive counter plates;
at least one of said electrically conductive counter plates being a transparent electrically conductive plate comprising a transparent substrate and a transparent electrode disposed inside the transparent substrate; and
at least one of said transparent electrically conductive plates comprising an ultraviolet absorbing layer between said transparent substrate and said transparent electrode, said ultraviolet absorber layer comprising a resin material and an organic ultraviolet absorber chemically bonded to said resin material.
