Abstract
An electrochromic display device for use in automobiles, etc. comprises a plurality of mutually parallel strip-shaped display electrodes, a plurality of mutually parallel strip-shaped opposite electrodes, electrochemically-color-developing solid layers, solid electrolyte layers as intermediate layers, and an electrically insulating layer. The display electrodes and the opposite electrodes are arranged so as to three-dimensionally intersect each other. The electrochemically-color-developing solid layers and the solid electrolyte layers are present only at the spaces formed by the intersection between the display electrodes and the opposite electrodes. The electrically insulating layer occupies all portions other than the electrodes, electrochemically-color-developing solid layers and solid electrolyte layers within the device.
