ABSTRACT:
An electrophoretic matrix display panel is composed of a first insulating substrate having a first set of strip-shaped parallel electrodes thereon and a voltage non-linear resistive layer on the first set of parallel electrodes. Dot-shaped intermediate electrodes isolated from each other are positioned on the voltage non-linear resistive layer, and an electrophoretic suspension layer consisting of a suspending medium and at least one electrophoretic material suspended therein is placed over the intermediate electrodes and contained thereon by a frame. A second set of parallel electrodes extending in a direction transverse to the direction of the first set of electrodes is placed over the frame and the electrophoretic suspension layer, and a second insulating substrate is provided thereover. The two sets of parallel electrodes cross to define cross points at which the dot-shaped intermediate electrodes are positioned and which constitute picture elements of the matrix display panel.
