摘要： An electrochromic display devices using a specific type of diphenylamine as an electrochromic material is described. The diphenylamine compound, which is dissolved in an inert solvent along with an electrolyte, can undergo electrochemically reversible color formation and erasure reactions and form two different colors at one of electrodes on application of two different potentials across the electrodes. Multicolor devices are also described in which the diphenylamine compound capable of forming colors by oxidation is used in combination with an anthraquinone compound which is capable of forming a color, different from the colors of the oxidized species of the diphenylamine coumpound, at the same electrode by reduction.
