Abstract
An electrophoretic display device includes a display layer comprised of a binder having a multiplicity of individual cavities therein that contain a display medium, and conductive substrates, at least one of the conductive substrates being transparent, wherein the display layer is located in between the conductive substrates, and wherein the display medium comprises one or more set of colored particles in a dielectric fluid and has an electrical conductivity of about 10to about 10S/m. The display device may be made by forming composite particles comprised of a sacrificial binder and the one or more set of particles of the display medium; mixing the composite particles with the binder to form a mixture; forming a layer from the mixture; removing the sacrificial binder from the composite particles in the layer to form cavities in the layer that contain the one or more set of colored particles; and filling the cavities with the dielectric fluid.
