Abstract
An electrophoretic display device includes a common electrode, pixel electrodes, and a disperse system of electrophoretic particles. A transistor supplies one of the pixel electrodes with a first potential or a second potential higher than the first potential. During a first period, a control portion supplies a third potential to the gate electrode to turn on the transistor, supplies the first potential to a signal line or the common electrode, and supplies the second potential to the other line. During a second period, the control portion supplies a fourth potential higher than the third potential to the gate electrode to turn off the transistor, and supplies the first potential to both the signal line and the common electrode so that the pixel electrode potential substantially reaches the common electrode potential. The third potential is lower than the second potential and the fourth potential is higher than the first potential.
