Beschreibung
Zusammenfassung:	An electrophoretic dispersion solution includes a nonpolar solvent and plural kinds of electrophoretic particles. At least one kind of the electrophoretic particles has, on surfaces, a copolymer including a first monomer that has a charged group and a second monomer expressed by a first formula represented as denotes a hydrogen atom or a methyl group, R' denotes a hydrogen atom or an alkyl group with a carbon number of 1 through 4, n is a natural number, and x denotes an integer of 1 through 3. At least another kind of the electrophoretic particles include, on surfaces, a polymer including a third monomer expressed by a second formula represented as as a component of the polymer. R denotes a hydrogen atom or a methyl group and R'' denotes an alkyl group with a carbon number of 4 or larger.
