Abstract
An electrophoretic display device is described where a set of anode electrodes in an electrophoretic cell are disposed opposite row and column electrodes at a second side of the electrophoretic cell. The anode electrodes encompass equal pluralities of at least the row electrodes, and such equal pluralities of electrodes are connected in parallel. This significantly reduces the number of leads to the display.
