Abstract

See full text

In an electrophoretic material, first particles which are charged with a first polarity and second particles which are charged with a second polarity are dispersed in a solvent. A volume, which is obtained by dividing a volume of the solvent by a total number of particles, is called free volume, and a radius of a spherical space, which is occupied by sum of an average volume of the particles and the free volume, is called a free volume radius. A first particle average radius is greater than a second particle average radius. A difference between the free volume radius and the first particle average radius is greater than the second particle average radius.
