Beschreibung
Zusammenfassung:	A particle dispersion and the display devices in which the dispersion may be incorporated are provided. The particle dispersion includes a dispersion medium, one or more types of particle groups that are dispersed in the dispersion medium that may differ based on color and/or charge, and counter-ions oppositely charged than the one or more particle groups. The particle groups and counter-ions are moved in the dispersion medium according to an electric field formed in the dispersion medium. The one or more types of particle groups are configured such that the total amount of charges of one type of particle group (a) among the one or more types of particle groups is greater than a total amount of charges of the counter-ions that are charged with a polarity opposite to that of the particle group (a).
