Abstract
An electrophoretic sheet includes a substrate having one surface and the other surface, a microcapsule-containing layer comprised of a plurality of microcapsules, the microcapsule-containing layer provided on the other surface of the substrate, each of the plurality of microcapsules having a capsule body and an electrophoretic dispersion liquid contained in the capsule body, the electrophoretic dispersion liquid containing a plurality of electrophoretic particles of at least one color, and the capsule body having an inner circumferential surface and an outer circumferential surface, and at least one colored part provided on the external side of the inner circumferential surface of the capsule body of each of the plurality of microcapsules, and wherein each colored part has a color complementary to the color of the plurality of electrophoretic particles. By using the electrophoretic sheet mentioned above, it is possible to provide the increased whiteness in display of the electrophoretic particles. An electrophoresis apparatus provided with such an electrophoretic sheet is also provided. By using the electrophoresis apparatus, it is possible to provide a superior contrast ratio. It is also possible to obtain high reliability. A Method for manufacturing such an electrophoresis apparatus is also provided. An electronic device provided with such an electrophoresis apparatus is also provided.
