Patent ID: 8054288

Claim:
An image display device comprising, a pair of substrates; one substrate of the pair of substrates where a first pixel electrode and a second pixel electrode arranged on the first pixel electrode are formed; another substrate, where an opposite electrode is formed, arranged opposite to the above described one substrate; a plurality of bulkheads dividing the spacing between the one substrate and the other substrate into a plurality of pixel regions; two kinds of charged particles filling, in plurality, to a pixel region surrounded by the one substrate, the other substrate and the bulkheads and being different in color and in charged polarity; and a first insulating layer and a second insulating layer; wherein the first insulating layer having a first insulating portion and a first opening, the second insulating layer having a second insulating portion and a second opening, the first insulating portion being formed between the first pixel electrode and the second pixel electrode, the first opening being formed on the first pixel electrode, the second insulating portion and the second opening being formed on the second pixel electrode, the first pixel electrode coming into contact with one charged particle of two kinds of charged particles in the first opening; and the second pixel electrode coming into contact with the other charged particle of the two kinds of charged particles in the second opening; wherein potential between the first pixel electrode and the opposite electrode and between the second pixel electrode and the opposite electrode is controlled to display an image.
