Abstract:
An electrophoretic display unit having a first substrate and a second substrate counterposed with an interspace, an insulating liquid placed in the interspace, and colored charged electrophoretic particles dispersed in the insulating liquid, and having a stage formed in the interspace along the second substrate,the stage having a first surface facing a thicker layer portion of the insulating liquid on the second substrate, a second surface facing a thinner layer portion of the insulating liquid, and a side wall surface of the stage connecting the first surface and the second surface, a first display electrode placed along the first surface, a second display electrode placed along the second surface, and a third electrode placed under the second electrode, wherein an end portion of the third electrode is proximate to the side wall surface at a substantially constant distance from the first electrode and the second electrode.
