ABSTRACT:
An image display medium comprises a display substrate on which an image is displayed and a non-displaying substrate opposing to the substrate, wherein a spacer and black particles and white particles are enclosed between these substrates. The display substrate and non-display substrate each have a transparent electrode, wherein the transparent electrode for the non-display substrate is grounded and the transparent electrode for the display substrate is connected to voltage applying means. As these black particles and white particles, particles for a display device having a weight reduction rate of not more than 0.3% at 100° C. to 240° C. are respectively used.
