ORGANIC ELECTROCHROMIC DEVICE, OPTICAL FILTER, LENS UNIT, AND IMAGING APPARATUS
First Claim
1. An organic electrochromic device, comprising:
- a pair of electrodes; and
an electrochromic layer arranged between the pair of electrodes,wherein;
the electrochromic layer contains an organic electrochromic material, a redox substance, and a solvent;
the organic electrochromic material and the redox substance each comprise a material to be reversibly subjected to a redox reaction; and
a potential at which the redox substance is oxidized is present between a potential at which the organic electrochromic material is reversibly oxidized and a potential at which the organic electrochromic material is irreversibly oxidized, or a potential at which the redox substance is reduced is present between a potential at which the organic electrochromic material is reversibly reduced and a potential at which the organic electrochromic material is irreversibly reduced.
