Abstract
An electrophoretic device 20 of the present invention has an electrode 3 formed on a first substrate 1, a transparent electrode 4 formed on a second substrate 2, and microcapsules 40 accommodated between these electrodes 3 and 4, in which the microcapsules 40 enclose an electrophoretic dispersion 10 which contains a liquid-phase dispersion medium 6 and electrophoretic particles 5. In this electrophoretic device 20, wall films of the microcapsules at a viewing side are colored by a printing technique.
