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.
