An electrochromic device having a conductive layer having reflectiveness and light absorption characteristics simultaneously. The device is capable of realizing various esthetic senses, color senses or stereoscopic color patterns, and at the same time has excellent durability.

Electrochromic device

A method for preparing an electrochromic device. In the method the device is prepared by inserting monovalent cations into a reducing electrochromic layer in advance, for instance, through a dry process. In particular, the method involves inserting monovalent cations into an electrochromic layer which includes a reducing electrochromic material. Then, subsequently and sequentially, placing an electrolyte layer and an ion storage layer on the electrochromic layer. In this way, it is possible to improve driving durability of the electrochromic device.

Method for preparing an electrochromic device

An electrochromic device including an electrode layer, an electrochromic layer and a conductive band having a closed ring shape. The electrochromic device having the above structure has excellent color-switching speeds and electrochromic uniformity.

An electrochromic film, which is a reflective electrochromic film, which includes an electrode layer, a light absorbing layer and an electrochromic layer. The film can improve an electrochromism rate and realize various colors or esthetic senses.
