An electrophoretic display device capable of realizing a stable memory characteristic without relying on a circuit-open state is provided. The electrophoretic display device has a cell structure including at least two electrodes, fixing surfaces each associated with one of said at least two electrodes, an electrophoretic layer disposed in the cell and comprising an insulating liquid and colored charged particles disposed in the electrophoretic layer, and voltage application device for applying a voltage between the electrodes thereby causing migration of the colored charged particles toward and collective attachment onto one of the fixing surfaces; wherein at least one of the timing surfaces and the colored charged particles is provides with an adhesive layer allowing repetitive attachment thereto and separation therefrom of the colored charged particles; or the fixing surfaces are provided with a charged film having a constant surface charge of a polarity opposite to that of the colored charged particles.
