An image display device and driving method thereof produce a multiple color display without inviting a drop in resolution, or with the drop in resolution suppressed. Between a back substrate and a transparent display substrate forming the image display surface, the image display part has in order a display electrode on which a transparent surface coating is formed, a spacer, and a back electrode on which a surface coating is formed. A voltage control part applies a -350 V dc voltage, for example, to the display electrode to display black by black particles, applies an approximately +350 dc voltage to the display electrode to display white by white particles, and applies, for example, a +/-500 V particle drive voltage pulse repeatedly to the display electrode to make the black and white particles clump together inside the unit cell, thereby making the unit cell transparent to produce a transparent display.
