Electrophoretic matrix panel

Claim 1

An electrophoretic matrix display panel comprising a first insulating substrate having a first set of strip-shaped parallel electrodes thereon, a voltage non-linear resistive layer on said first set of parallel electrodes, said non-linear resistive layer being SiC particles having an average grain size smaller than 5μ in urea resin, said SiC particles and urea resin being mixed in a weight ratio of from 2:3 to 2:10, dot-shaped intermediate electrodes isolated from each other and positioned on said voltage non-linear resistive layer, an electrophoretic suspension layer consisting of suspending medium and at least one electrophoretic material suspended in said suspending medium, a frame around the periphery of said panel, and a second insulating substrate having a second set of strip-shaped parallel electrodes thereon; at least said second insulating substrate and said second insulating substrate being attached to said first insulating substrate through said frame and said second set of parallel electrodes extending in a direction transverse to the direction of said first set of parallel electrodes and crossing said first set of parallel electrodes to define cross points between the respective elements of the sets of electrodes the cross points between said first and second sets of parallel electrodes constituting picture elements of said matrix display panel, said dot-shaped intermediate electrodes being positioned at the cross points between said first and second sets of parallel electrodes.
