Abstract
There is provided electrophoretic particle which has core particle, and a siloxane-based compound which includes a connecting structure in which a plurality of siloxane bonds are connected in series, and the surface of the core particle includes a first region to which the siloxane-based compound is bonded, and a second region in which charging characteristic derived from the core particle is expressed by exposure of the surface of the core particle. An occupancy rate of the first region on the surface of the core particle is preferably equal to greater than 0.05% and equal to or less than 20%.
