An electrochromic device comprising a pair of glass or plastic plates or plastic films of which at least one plate or film, preferably both plates or films, are provided on in each case one side with an electrically conductive coating, of which at least one plate or film and its conductive coating are transparent, of which the other may be mirrored, and of which in the case of at least one of the two plates or films the electrically conductive layer can be divided into separate, individually contacted area segments, in which the plates or films are joined together via a sealing ring on the sides of their conductive coating, and the volume formed by the two plates or films and the sealing ring is filled with an electrochromic medium, wherein the electrochromic medium comprises a pair of electrochromic substances OX2n+ and RED1m-, in which n and m, independently of one another, are integers from 2 to 4. solves the problem of unsharp imaging by diffusion.
