Patent ID: 8730561

Claim:
An electrophoretic display device, comprising: a first display substrate including a base substrate and at least three pixel regions, each of the pixel regions including a first electrode and a second electrode, the first electrode and the second electrode being on the base substrate; and a second display substrate facing the first and second electrodes and including at least one third electrode opposing the first and second electrodes in each of the pixel regions, wherein: each of the pixel regions further includes an electrophoretic layer between the first display substrate and the second display substrate, the electrophoretic layer including a plurality of first charged particles, a plurality of second charged particles, and a colored solvent, the first and second charged particles having different polarities from each other, and the colored solvent having a chromatic color, each of the pixel regions is configured to display a black color or a white color using a vertical electric field between the third electrode and the first and second electrodes, and is configured to display a chromatic color using a horizontal electric field between the first electrode and the second electrode, a second pixel region is between adjacent first and third pixel regions, and the second pixel region is to display a chromatic color at a time when the first and third pixel regions are to display a same one of the black color or the white color.
