Electrochromic device and method of fabricating the same

A method for fabricating an electrochromic device, the method comprising:

• forming a first electrode, and forming a second electrode disposed opposite the first electrode,
• further forming a carbon nano-structured electrode layer as a counter electrode, on the first electrode;
• forming an electrochromic layer on the second electrode;
• and
• forming an electrolyte layer between the first electrode and the second electrode,
• wherein
• the second electrode comprises a plurality of portions separated from each other and corresponding to different color portions of a pixel;
• the counter electrode consists essentially of the carbon nano-structured electrode layer and excludes TiO2;
• and
• the carbon nano-structured electrode layer is completely formed at a temperature of about 150 degrees Celsius or less.
