An electrophoresis dispersion liquid includes first electrophoretic particle of a scattering system having an ionic group on a surface thereof; second electrophoretic particle of a coloring system having a polarization group on the surface thereof; and a dispersion medium. It is preferable that the ionic group is an acidic group, and further includes a ring structure that forms an acidic group and a salt. It is preferable that the polarization group is an organic group having a main skeleton, and a substituent bonded to the main skeleton.

An electrophoretic particle includes a base particle (particle), a first compound, a second compound, and a third compound bonded to the base particle. The first compound is a polymer having a dispersion portion derived from a first monomer, and a bonding portion derived from a second monomer, and is connected to the base particle at the bonding portion. The second compound includes a non-polar group and a second functional group and is connected to the base particle at the second functional group. The third compound includes a charging group and a second functional group and is connected to the base particle at the second functional group.
