An electrophoresis device includes a first substrate having a plurality of pixel electrodes formed on a surface thereof, a second substrate having a common electrode formed on a surface thereof and disposed to face the pixel electrodes, and an electrophoretic layer disposed between the pixel electrodes and the common electrode. The electrophoresis device makes electrophoretic particles migrate by keeping the potential of each pixel electrode constant and changing a voltage to be applied to the common electrode. The device also includes a voltage control means which supplies a voltage whose minimum voltage is not less than V3 and whose maximum voltage are not more than V4 to the common electrode, in a case where a potential which appears in each pixel electrode when a minimum voltage V1 is supplied to a voltage supply means to each pixel electrode is set to V3 and a potential which appears in each pixel electrode when a maximum voltage V2 is supplied to the voltage supply means is set to V4. |
