Abstract
An electrochromic display device includes a transparent first electrode and a second electrode opposing said first electrode to be spaced apart therefrom. An electrochromic layer is formed in a space formed between the first and second electrodes so as to be in contact with the first electrode. The electrochromic layer is formed of certain naphthalene derivatives, certain tetracene derivatives or certain fulvalene derivatives. An ionic conductor layer is formed in the space so as to be in contact with the electrochromic layer.
