ABSTRACT:
An electrophoretic display device comprises a first substrate and a second substrate positioned to face each other. A first electrode is so mounted to the first substrate as to face second and third electrodes. The second and third electrodes have an area smaller than that of the first electrode. Also, the distance between the second and third electrodes is set shorter than the distance between the second and first electrodes and the distance between the third and electrodes. A suspension dispersing charged fine particles in an insulating liquid medium is interposed between the first electrode and the second and third electrodes. An AC voltage is applied between the second and third electrodes, and a DC voltage is applied between the first electrode and the second and third electrodes. Thus, the migration of charged fine particles are controlled in accordance with the dielectrophoretic and electrophoretic forces.
