An electrophoretic display device has an electrophoretic display panel that has a plurality of drive electrodes, a common electrode, and a plurality of electrophoretic particles disposed between the drive electrodes and the common electrode, and can update the display color of each display unit correlated to a particular drive electrode as a result of the electrophoretic particles moving according to a voltage applied between the drive electrode and the common electrode; and a drive control unit that applies voltage between the drive electrodes and the common electrode to update the display of the electrophoretic display panel. The electrophoretic display device can display a plurality of colors including a first color and a second color in each of the display units. The drive control unit includes a display color setting means that sets for each display unit an updated display color indicating the color to be displayed after the display unit is updated, a first pulse-applying means that applies a first pulse between the common electrode and the drive electrode of at least one display unit, and a second pulse-applying means that applies a second pulse between the common electrode and the drive electrode of at least one display unit. To the display units for which the updated display color is set to the first color or the second color, the first pulse-applying means applying the first pulse to display in said display units the first color or second color that is different from the color to be displayed after updating, and the second pulse-applying means applying a second pulse that is opposite polarity to the first pulse in the same amount as the first pulse to change said display units to the set display color.
