PROBLEM TO BE SOLVED: To provide an electrophoresis display device capable of displaying an information by an electric signal inputting with handwritten input and maintaining a sample on a display. SOLUTION: An electrophoresis display device E1 comprises a microcapsule 3 sealing a dispersion system of electrophoresis particles and a dispersion medium. The device has a double layer structure comprising a display portion, which makes the electrophoresis particles move by an electric field effect and displays a photo-receiving type, which has no light-emitting itself, so-called a photo- reflecting type electrophoresis display, and a magnetic layer 6 of a ferromagnetic material or a paramagnetic material set so as to line the backside of the display portion. Written input and erasure are carried out by a potential difference charged between a common electrode 4 forming an electric field and an input pen 7. Further a paper sheet 29 is held between the display portion and the carrier 28 by force generated from magnetism between the carriers 28 consisting of the ferromagnetic material or the paramagnetic material and the magnetic layer 6.
