Patent ID: 7277219

Claim:
A particle movement display device, comprising: a pair of front-side first substrate and rear-side second substrate disposed opposite to each other with a spacing therebetween; a partition wall, disposed between said first and second substrates, for partitioning the spacing into a plurality of sections; charged particles disposed in each of the sections; a first electrode disposed on a surface of said first substrate in each section; and a second electrode and a third electrode which are disposed on surfaces, other than the surface of said first substrate, in each section, and between said second electrode and said third electrode, a voltage being applied so as to move said charged particles in each section to display an image, wherein the surface of said first substrate in each section has a first area in which said first electrode is formed and a second area in which said first electrode is not formed, wherein said third electrode is formed on a surface of said partition wall in each section or on a surface of said second substrate contacting said partition wall in each section and has an electric potential common to the plurality of sections.
