In an image display device which includes an image display panel, in which two or more groups of particles having different colors and different charge characteristics are sealed in a plurality of cells formed by partition walls between two substrates, at least one of two substrates being transparent, and, in which the particles, to which an electrostatic field produced by electrodes provided to both of the substrates is applied, are made to move so as to display an image, as the electrodes provided on two substrates, use is made of a pattern electrode patternized in such a manner that a coating area of the electrode satisfies a predetermined condition with respect to a projected area of respective cells (first invention) or a pattern electrode patternized in such a manner that no electrode portion is formed at a vertically lower portion in respective cells (second invention).
