Abstract
To provide an electrophoretic dispersion capable of reducing or preventing the aggregation of electrophoretic particles, an electrophoretic display device using the electrophoretic dispersion, a method of manufacturing the electrophoretic display device, and an electronic system superior in display performance; an electrophoretic display device (electrophoretic display unit) has: a first substrate with a first electrode; a second substrate with a second electrode opposite the first electrode; and an electrophoretic dispersion provided between the first substrate and second substrate. The electrophoretic dispersion (dispersion for electrophoretic display units) includes a liquid phase insulative dispersion medium and electrophoretic particles dispersed in the dispersion medium, the particles electrophoretically migrated under an influence of an electric field. Also included as the electrophoretic particles, inorganic particles and resin particles dyed a color different from that of the inorganic particles and having an electrical polarity opposite to that of the inorganic particles.
