Abstract
In particles for image displaying used in an image display device, in which one or more kind of particles are sealed between opposed substrates, at least one substrate being transparent, and, in which the particles are made to fly and move so as to display an image, each particle has a micro-irregularity at its surface. Moreover, in an image display device, in which one or more kind of particles are sealed between opposed substrates, at least one substrate being transparent, and, in which the particles, to which an electrostatic field produced by two kinds of electrodes having different potentials is applied, are made to fly and move so as to display an image, use is made of each particle having a micro-irregularity at its surface.
