Electrochromic display device
 An electrochromic display device having a simplified driving circuit. A colored display is performed by injecting an electric charge into the electrochromic layers of predetermined segments. The electric charge is transferred to the electrochromic layers of the other segments by applying a DC electric field between the predetermined segments and other segments to thereby change the display state.
