PROBLEM TO BE SOLVED: To provide an electrophoretic display device which has solvent resistance and particle stability. SOLUTION: An electrophoretic display medium (30. 31, 32) includes one or more sets of colored particles in a dielectric fluid, wherein at least one of the one or more sets of particles comprises poly((meth)acrylate/hydrophilic monomer) emulsion aggregation polymer particles such as poly(methyl methacrylate/butyl acrylate/beta-carboxyethylacrylate) emulsion aggregation polymer particles. The display medium is included in an electrophoretic display device by including the medium in a multiplicity of individual reservoirs of a display layer 40 or layers that is located between conductive substrates.
