Electrophoretic display devices and contactless communication media are
provided. A display electrode pattern, a first voltage application
circuit to apply a voltage between the display electrode pattern and a
transparent electrode, and a wiring pattern that electrically conducts
the first voltage application circuit and the display electrode pattern
are provided on the side of the back surface of a substrate. Also, a BG
electrode pattern, a loop pattern of a predetermined height, and the
transparent electrode are provided on the side of the surface of the
substrate. Multiple electrophoretic particles and a dispersion medium to
disperse the electrophoretic particles are enclosed inside the loop
pattern and between the substrate and the transparent electrode. A
voltage is applied between the transparent electrode and the display
electrode pattern by the first voltage application circuit thereby
causing the electrophoretic particles to migrate in the dispersion medium
to display a desired image.
