Abstract
A particle-movement display device includes 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 the first and second substrates, for partitioning the spacing into a plurality of sections, and charged particles disposed in each of the sections. A first electrode is disposed on a surface of the first substrate in each section, and a second electrode is disposed on a surface of the second substrate in each section. The first electrode in each section has a lattice-like shape, a pitch of which is smaller than a pitch of the partition wall.
Claims5
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.
