Abstract
For an electro-optical display having an electrochromic material provided with a redox pair and sandwiched between a pair of electrodes, a first potential more negative than the threshold potential is applied and a second potential more positive than the first potential but more negative than the threshold potential is thereafter applied in a write mode.
