Abstract
An electrophoretic display device includes a substrate, a partition wall disposed on a surface of the substrate, and a liquid layer, disposed in a container defined by the substrate and the partition wall, including electrophoretic particles and a dispersion medium. In addition, a first electrode is formed at a position apart from the partition wall on the substrate, a second electrode is formed along the partition wall, and a voltage applicator applies a voltage between the first electrode and the second electrode. At the surface of the substrate defining the container, a resistance layer electrically connecting the first electrode and the second electrode is formed, and the electrophoretic particles in the container are moved between a surface of the partition wall and a surface of the resistance layer to effect display.
