Abstract: An electrochromic display device comprises terminals formed on one of two substrates for connecting the electrochromic display device to a driver circuit, and one or more cut-off and lead-in electrodes each for connecting display segments to corresponding terminals. The cut-off and lead-in electrodes are adapted to have resistance values such that the results of a multiplication of each of the resistance values and the area of a corresponding one of the display segments are approximately constant as compared to remaining couples of the remaining display segments and corresponding lead-in electrodes. Each of the cut-off and lead-in electrodes has a cut-off portion not available for electrical interconnection. In another form of the present invention, the lead-in electrodes, regardless of whether or not the cut-off portion is present, are formed on a substantially entire surface of one of the two substrates so that gaps therebetween are not noticed by a visual scale.
