Document Type and Number:
WIPO Patent Application WO/2004/059379
Kind Code:
A1
Abstract:
An image display having an image display sheet wherein two kinds of particles, white positively-charged particles and black negatively-charged particles, both different in color and charging characteristics are sealed in cells divided by partitions between a transparent substrate and an opposed substrate, an electric field is applied to the particles by using display electrodes provided on the transparent substrate and opposed electrodes provided on the opposed substrate, and the particles are moved to display an image. The electrodes (4) arranged on the two substrates are patterned in such a way the relationship between the covering area of each electrode and the projection area of each cell satisfies a predetermined condition (first invention), or in such a way that no electrode is present in the vertically lower portion of each cell when the image display sheet is set vertically (second invention).
