Abstract:
1. An electrophoretic display device comprising: a common electrode; a plurality of pixel electrodes; a disperse system including electrophoretic particles, the disperse system being held between the common electrode and the plurality of pixel electrodes; a switching transistor that supplies a corresponding one of the plurality of pixel electrodes with a first electric potential signal or a second electric potential signal that is higher than the first electric potential signal, wherein the first electric potential signal or the second electric potential signal is supplied from a signal line; and a control portion that controls electric potential signals supplied to the pixel electrode and the common electrode to cause the electrophoretic particles to move, wherein: the switching transistor enters an on state when a gate electrode of the switching transistor is supplied with a third electric potential signal, and enters an off state when the gate electrode is supplied with a fourth electric potential signal that is higher than the third electric potential signal; during a first period, during a second period that is after supplying the first or second electric potential signal to the corresponding one of the plurality of pixel electrodes, the third electric potential signal is lower than the second electric potential signal and the fourth electric potential signal is higher than the first electric potential signal; and the control portion:
