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.
