Abstract

There is provided a method of manufacturing an electrophoretic particle, in which the electrophoretic particle includes a mother particle and a block copolymer, including: a step of polymerizing a monomer M having a site contributing to dispersibility into a dispersion medium, a monomer M including a second functional group having reactivity with the first functional group, a charged monomer M by living polymerization without random copolymerizing the monomer Mand the monomer Mso as to obtain the block copolymer; and a step of reacting the first functional group and the second functional group to a bonding section to a mother particle so as to connect the block copolymer to the mother particle.
