An image display medium has: a display substrate that is at least
transparent; a back substrate opposing the display substrate with a gap
therebetween; at least two or more kinds of moving particle groups that
are chargeable and that are different colors, the moving particle groups
being enclosed between the display substrate and the back substrate and
moving between the substrates in accordance with an electric field formed
between the substrates; a transparent liquid for dispersing the moving
particles, the transparent liquid being enclosed between the display
substrate and the back substrate; and a colored member disposed between
the display substrate and the back substrate, and having gaps through
which the moving particle groups can move, and being a color that is
different from the colors of the moving particle groups.
