In an information display device which comprises an information display panel, in which at least one group of particles are sealed in a plurality of cells formed by partition walls between the opposed substrates, at least one of two substrates being transparent, and, in which the particles, to which an electrostatic field is applied by utilizing electrodes arranged to the substrates respectively, are made to move so as to display information such as an image, when D is assumed to be a particle diameter of the particle (constituting the particles) and H is assumed to be a height of the substrate, the following relation is satisfied: D≧2H, so that a surface of the substrate is made to be smooth. In this manner, the information display device is provided, which improves a contrast ratio after endurance due to the smooth substrate surface by making a thickness of the electrode as thin as possible (by making a height of the electrode as small as possible).
