Patent ID: 6897996

Claim:
An electrophoretic display device comprising: a display-side substrate and a rear-side substrate positioned with a predetermined clearance therebetween; a cell wall placed at a periphery of a pixel in order to keep the clearance constant between the two substrates; a dispersing fluid placed in the clearance between the two substrates; a plurality of colored, charged particles dispersed in the dispersing fluid; a first electrode placed in each pixel; and a second electrode placed at a periphery of each pixel and demonstrating a color different from a color of the first electrode, wherein a voltage is applied between the first electrode and the second electrode to move the charged particles between a surface of the first electrode and a side face of the cell wall and the vicinity thereof, thereby implementing display, and wherein the first electrode is formed on the rear-side substrate and the second electrode is formed at one or more positions among a location between the cell wall and the display-side substrate, a location between the cell wall and the rear-side substrate, and a location inside the cell wall.
