Abstract:
1. A display device comprising: a pair of substrates disposed opposite to each other, at least one of which is transparent; a plurality of particles having an electrostatic property contained in a gaseous phase provided between the pair of substrates; first and second electrodes provided for each of pixels arranged in a matrix for driving the particles; and a voltage applying portion for applying voltage to the first and second electrodes in accordance with an image signal, wherein: the particles each comprise a parent particle as a core, and plural child particles fixed to the parent particle in a manner to cover a substantially entire surface of the parent particle; and when voltage is applied to the first and second electrodes by the voltage applying portion, the particles are caused to travel between the first and second electrodes in accordance with the voltage applied so as to display an image corresponding to the image signal.
