Patent ID: 8810895

Claim:
An electrophoretic display device, comprising: an array substrate comprising a first base substrate and a pixel electrode, wherein the first base substrate comprises a plurality of pixel regions, and the pixel electrode comprises a plurality of electrode patterns disposed in each of the pixel regions; an opposing substrate comprising a second base substrate and a common electrode, wherein the second base substrate is positioned opposite to the first base substrate, and the common electrode is disposed on a surface of the second base substrate that faces the first base substrate; and an electrophoretic layer disposed between the array substrate and the opposing substrate, and comprising a plurality of polarity particles dispersed in a non-polar solvent, wherein the common electrode comprises a plurality of openings disposed in a region corresponding to each of the electrode patterns, and each one of the plurality of openings is overlapped with a corresponding one of the plurality of electrode patterns, wherein an area of each of the openings is about equal to or greater than an area of a corresponding electrode pattern.
