Disclosed is an electrochromic mirror or window. The electrochromic mirror or window includes a first substrate including a first electrode, a second substrate including a second electrode, an electrolyte filled in a gap formed between the first and second substrates and including ions related to an electrochromic reaction, and an electrochromic layer provided on the second electrode to change its color depending on an electric signal applied thereto. The electrochromic layer is patterned on the second electrode with a predetermined configuration to display information. The electrochromic mirror or window displays information, such as messages, pictures or time, by patterning the information in the electrochromic layer.
