Abstract
An electrochromic display device includes an electrochromic display element including a display electrode, an electrochromic layer provided on the display electrode, an opposing electrode facing the display electrode, and an electrolyte layer sandwiched between the display electrode and the opposing electrode. The electrochromic display device further includes a switching element, and a electric storage element. The display electrode is connected with the opposing electrode by a power source or the electric storage element via the switching element, and when performing driving, part of electric charges, which are stored in the electrochromic display element, are applied for charging the electric storage element, or electric charges in the electric storage element that has been charged are used for driving the electrochromic display element.
