Abstract: An electrophoretic display device includes a first substrate and a second substrate disposed opposite each other, a dielectric liquid filled in a gap between the first substrate and the second substrate, a plurality of charged electrophoretic particles dispersed in the dielectric liquid, a first electrode and a second electrode disposed on the first substrate to define a pixel, a partition wall disposed on at least one of the first substrate and the second substrate between adjacent pixels to prevent migration of the charged electrophoretic particles between the adjacent pixels, and a third electrode disposed adjacent to the partition wall. The charged electrophoretic particles migrate at least between a surface of the first electrode and a surface of the second electrode, and between the surface of the first electrode and a side surface of the partition wall where the third electrode is disposed to thereby switch displays.

Abstract: The present invention provides a horizontally transfer type electrophoretic display device that can suppress occurrence of cross-talk and is capable of passive matrix addressing that can obtain a good display. The display device includes a fist display electrode and a second display electrode disposed on a first substrate, a second substrate being disposed in opposed relation to the first substrate via a barrier wall, a first control electrode as one of the two control electrodes disposed on the second substrate, and a second control electrode disposed at the boundary between the first display electrode and the second display electrode on the first electrode. A voltage can be independently applied to each control electrode, a transparent insulation liquid is filled in the space formed by the both substrates and the barrier wall, and colored and charged particles are dispersed in the transparent insulation liquid.

Abstract: A novel electrophoretic display unit is provided. The electrophoretic display unit has a first substrate and a second substrate conterposed 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 on the second substrate, the stage giving 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, wherein a third electrode is provided along an intersection line of an imaginary plane placed at a prescribed distance from the second surface and nearer to the first surface than the second surface and the side wall surface.
