Abstract
A method for making an electrophoretic solution includes: including two kinds of particles having different charging polarities into the electrophoretic solution; calculating a mixing ratio so that charge amounts of the two kinds of particles become approximately equal to each other on a basis of a unit volume of a dispersion medium; and mixing the two kinds of particles in each mixed quantity that satisfies the calculated mixing ratio.
