An electrochromic display cell includes a predetermined number of display segments, different combinations of the display segments defining different desired display patterns. A drive system is provided for the electrochromic display cell, which functions to apply a coloration voltage write-in signal to a selected display segment which should be changed from the bleached state to the coloration state upon change of the display data. After completion of the write-in operation, the electrochromic display cell is held in an electrically opened state for a predetermined period of time, and then the display segments which are in the coloration state are electrically connected with each other in order to uniform the coloration degree of each of the colored display segments.
