1. A method of manufacturing a color electrophoretic display comprising the steps of:

  • (a) providing a substrate having at least two electrodes disposed thereon;

    (b) selectively depositing a first plurality of electrophoretic display elements in substantial registration with a first electrode, each of said first plurality of display elements comprising a capsule containing a plurality of a first species of particles, said first species of particles responsive to a first applied electric field and having a first optical property; and

    (c) selectively depositing a second plurality of electrophoretic display elements in substantial registration with a second electrode, each of said second plurality of display elements comprising a capsule containing a plurality of a second species of particles, said second species of particles responsive to a second applied electric field and having a second optical property.
