Abstract
A driving device of a display medium that including first and second particle groups migrating independently due to a first voltage being imparted for a first time period, forming aggregates due to the first voltage being imparted for a second time period, and the aggregates migrating due to a second voltage being imparted. The driving device includes a voltage imparting section that: imparts a third voltage that moves, to a display substrate side, a greater-amount-needed particle group for gradation display, in an amount of a difference between particles of the first particle group and second particle group needed for the display; when the greater-amount-needed particle group has an opposite polarity to the aggregates, imparts a fourth voltage that moves the aggregates needed to the display substrate side; and when the polarities are same, imparts a fifth voltage that moves the aggregates not needed to a rear substrate side.
