According to example embodiments, an electrochromic device includes pixel containing a first sub-pixel and a second sub-pixel. The first sub-pixel includes a first electrolyte contacting a first electrochromic layer. The first electrochromic layer includes a first electrochromic material configured to display each one of transparency and at least two colors, based on a voltage applied to the first electrochromic material. The second sub-pixel includes a second electrolyte contacting a second electrochromic layer. The second electrochromic layer includes a second electrochromic material configured to display each one of transparency, black, and at least one color other than black, based on a voltage applied to the second electrochromic material.
