Patent ID: 7411721

Claim:
A particle-movement display device, comprising: a front-side first substrate and a 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, 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 in a lattice-like shape, and a second area in which said first electrode is not formed, wherein a pitch of said lattice-like first electrode is smaller than a pitch of the sections partitioned by said partition wall.
