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.
电泳粒子包括基粒(颗粒)、第一化合物、第二化合物和与基粒粘合的第三化合物。第一种化合物是一种聚合物,其分散部分来自第一种单体,粘合部分来自第二种单体,并在粘合部分与基质颗粒相连。第二种化合物包括一个非极性基团和一个第二官能团,并在第二官能团处与基质颗粒相连。第三种化合物包括一个带电基团和一个第二官能团,并在第二官能团处与基质颗粒相连。
