A multi-valued display is produced by an image display device using electronic balls. The image display device includes a first substrate and a second substrate and spherical bodies, which are sandwiched between the first substrate and the second substrate and which are rotatable. Each rotatable spherical body has at least two regions formed by dividing the spherical body in color, and at least first electrodes and second electrodes which apply an electric field to the rotatable spherical bodies. At least an electric field which is generated between the first electrode and the second electrode is applied to the rotatable spherical body, and the image display device further defines a plurality of regions which differ in the intensity of the electric field in the pixel.
