Claim Text:
1. A driving method of an electrophoretic display device, which has a plurality of pixels where an electrophoretic layer is interposed between a first electrode and a second electrode, and in a case when the potential of the first electrode is higher than the potential of the second electrode, the potential difference generated between the first electrode and the second electrode is a positive polarity, as a display state of one pixel out of the plurality of pixels, a white display state is selected by applying a voltage with the positive polarity and a black display state is selected by applying a voltage with a negative polarity different from the positive polarity, and a halftone between the white display state and the black display state is selected according to a total duration of the voltage with the negative polarity applied to the one pixel in the display state, comprising: applying a setting voltage pulse with the positive polarity such that the display state of the one pixel is set to the white display state; applying a compensating voltage pulse with the positive polarity to the one pixel, wherein the compensating voltage pulse is different from the setting voltage pulse and increases existing polarity between the first electrode and the second electrode; and applying a driving voltage pulse with the negative polarity to the one pixel, such that the one pixel is displayed in the halftone, wherein, the applying of the compensating voltage pulse is executed between the applying of the setting voltage pulse and the applying of the first driving voltage pulse.
