Abstract
A method of manufacturing electrophoresis particles having base particles exposing first functional groups on surfaces and block copolymers bonded to the base particles, the method including: obtaining the plurality of block copolymers in which dispersion portions formed by polymerizing monomers including side chains contributing to dispersibility in a dispersion medium and bonding portions formed by polymerizing second monomers including second functional groups having reactivity with the first functional group are bonded, by living polymerization; and bonding the bonding portions to the base particles by reacting the first functional groups and the second functional groups so that the block copolymers are bonded to the base particles.
