A display element in which reduced variation in color in the midtone has been achieved even when repeatedly driven is disclosed, comprising opposing electrodes and an electrolyte containing silver or a compound including silver in the chemical structure between the opposing electrodes, wherein the opposing electrodes are driven so that the silver is dissolved or deposited and the following requirement is satisfied: A1/A2>4 in which A1 (mA/cm2) is a maximum value of absolute values of an electric current applied between the opposed electrodes when driven in the direction of from a state of no silver being deposited on the side of the display electrode to that of the silver being deposited and A2 (mA/cm2) is a maximum of absolute values of an electric current applied between the opposing electrodes when driven in the direction of from a state of no silver being deposited on the side of the display electrode to that of the silver being dissolved. |
