Abstract
An image display medium provided with a pair of substrates both of which are substantially transparent, and a gas enclosed in space defined between them. Each of the pair of the substrates is provided with transparent electrodes (ITO). The space defined between the substrates encloses two types of particle groups having colors different from one another, have a negative charge polarity, and have different adhesiveness from each other with respect to the substrates. A white particle group having a positive polarity is further enclosed in the space. A voltage is applied to the electrodes and so as to apply an electric field determined in response to the types of particles to be transferred. Thus, a plurality of colors are selectively developed via the particle groups enclosed in the space for displaying different colors.
