ABSTRACT:
A display member having improved optical contrast and brightness. The display member includes bichromal capsules, an absorptive layer, an adhesive layer, a substrate and a top layer. The bichromal capsules form a close-packed monolayer configuration positioned on the absorptive layer. The adhesive layer is adjacent to the absorptive layer. The absorptive layer is formed on the substrate. The top layer is formed adjacent the adhesive layer. A method for producing a display member with high optical contrast and brightness. The method includes forming an absorptive layer on a substrate. A close-packed monolayer configuration of bichromal capsules is formed on the absorptive layer by exposing the absorptive layer to a plurality of bichromal capsules. A top layer is formed adjacent the adhesive layer.
