An electrophoretic display liquid composition for use in an electrophoretic display device that has a multiplicity of individual reservoirs, each containing the liquid, contains one or at least two sets of particles dispersed in a transparent and/or colored liquid system. The at least two sets of particles exhibit different, contrasting color and different charging properties from each other, while in the one particle system, the particles exhibit a different, contrasting color from the colored liquid. In all embodiments, at least one of the sets of particles are particles with adjustable morphology made from emulsion/aggregation process. The morphology of the particles is controlled to be from grape, cauliflower, raspberry, or potato up to substantially perfect spheres. The transparent liquid system may include two immiscible liquids having different densities with the sets of particles having densities in between the densities of the two immiscible liquids such that the particles rest at an interface between the two immiscible liquids.
An electrophoretic display device comprising a multiplicity of individual reservoirs, each containing an electrophoretic display fluid, located between two conductive film substrates, at least one of which is transparent, wherein the electrophoretic display fluid comprises at least two sets of particles dispersed in a transparent liquid system, the at least two sets of particles exhibiting different, contrasting color and different charging properties from each other, and wherein at least one of the sets of particles are emulsion/aggregation particles.
