Abstract
Disclosed are an electrochromic device and a method for fabricating the same. The electrochromic device comprises a transparent electrode, on which an electrochromic layer is formed, a counter electrode on which a reflective layer is formed, and an electrolyte layer interposed between the transparent electrode and the counter electrode. Since the electrolyte layer is formed in only an active region of unit pixels, neither crosstalk nor image diffusion occurs and only the selected region of unit pixels is operated. Thus, the electrochromic device can realize passive matrix displays capable of representing a desired color. Furthermore, the electrochromic device can be utilized in a variety of applications including flexible displays and electrical papers.
