1. An electrophoretic display comprising:

  • a. an arrangement of discrete microscopic containers, each container being no longer than 500 μ

    m along any dimension thereof;

    b. first and second electrodes disposed on and covering opposite sides of the arrangement, at least one of the electrodes being substantially visually transparent;

    c. means for creating a potential difference between the two electrodes; and

    d. within each container, a dielectric fluid and a suspension therein of particles exhibiting surface charges, the fluid and the particles contrasting visually, the potential difference causing the particles to migrate toward one of the electrodes.
