An image display medium including a pair of substrates, a transparent dispersion medium, one or more kind of colored particles and larger sized colored particles. The pair of substrates is disposed with a separation therebetween and at least one of the pair of substrates is transparent. The dispersion medium is transparent and enclosed between the pair of substrates. Each kind of the colored particles is colored a predetermined color, is dispersed in the dispersion medium, has predetermined charge characteristics or predetermined magnetic properties, and is able to migrate between the pair of substrates. The larger sized colored particles have a different color and a larger particle size than the colored particles, are disposed so that the colored particles are able to pass through the separation, have charge characteristics or magnetic properties which are different from those of the colored particles, and are able to move.
