    摘要: 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.
