Abstract
An electrochromic display device includes a display substrate, a counter substrate facing the display substrate, counter electrodes arranged on the counter substrate, an electrolyte layer arranged between the display substrate and the counter electrodes, display electrodes separately arranged from one another between the display substrate and the counter electrodes, electrochromic layers to develop or reduce a color by redox reactions, the electrochromic layers being formed on the respective display electrodes arranged such that the electrochromic layers face the set of the counter electrodes, a voltage applying unit to select one of the display electrodes to connect the selected display electrode and the counter electrodes to apply a voltage between the connected display electrode and counter electrodes, a disconnecting unit to disconnect the unselected display electrodes from the counter electrodes, and an interelectrode connecting unit to connect the display electrodes.
