Patent ID: 7605797

Claim:
A particle movement-type display apparatus, comprising: a plurality of pixels each comprising a first electrode, a second electrode, a third electrode, a partition wall, and a dispersion liquid for dispersing a plurality of particles to effect display, wherein the first electrode is disposed as part of the partition wall, the third electrode is disposed opposite to the second electrode, the partition wall extends from the second electrode to the third electrode so as to separate adjacent pixels, and the dispersion liquid is sealed in a closed space defined by the first electrode, the second electrode and the third electrode, and wherein, when predetermined voltages are applied to the first electrode and the second electrode so that the particles are gradually moved towards one of the first electrode and the second electrode, another voltage for generating an electric field is applied to the third electrode so as to press the particles against the first and second electrodes to effect a predetermined gradation level of display proportional to the predetermined voltages applied to the first electrode and the second electrode.
