An electrophoretic display unit has 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. A stage is formed in the interspace on the second substrate, with the stage having a first surface facing a thick layer portion of the insulating liquid, a second surface facing a thin 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 is placed along the first surface, a second display electrode is placed along the second electrode, and a third electrode is placed under the second electrode. An end portion of the third portion is proximate to the side wall surface at a substantially constant distance from the first electrode and the second electrode.
