ABSTRACT:
An electrophoresis device includes a pair of substrates, a plurality of pixel electrodes, and a common electrode formed on the pair of substrates, a liquid material formed by dispersing charged particles sealed between the pair of substrates and a driving circuit for applying a voltage to the pixel electrodes and the common electrode to generate an electric field therebetween. When display image is changed, the driving circuit generates a first electric field between all the pixel electrodes and the common electrode to delete the image displayed by that time over the entire display region. Then, when new display image is written, the driving circuit generates a second electric field between the pixel electrodes corresponding to display and the common electrode, and generates a third electric field between the common electrode and the pixel electrodes not corresponding to display.
