Abstract
A driving method of an electrophoretic display device, including a pair of substrates with an electrophoretic element which is interposed between the substrates and contains electrophoretic particles, a plurality of pixel electrodes formed at an electrophoretic element side of either one substrate of the pair of substrates, and a common electrode which opposes to the plurality of pixel electrodes and is formed at an electrophoretic element side of the other substrate, includes an image display step of inputting potentials, which are determined according to image data, to the plurality of pixel electrodes and a predetermined potential to the common electrode and displaying an image according to the image data by driving the electrophoretic element, and an image maintaining step of causing the plurality of pixel electrodes and the common electrode to have the same potential after the image display step.
