Abstract
An electrophoretic display device includes a common electrode, an electrophoresis layer, and pixel electrodes. The electrophoretic layer includes cavities, with each cavity arranged between one of the pixel electrodes and the common electrode, and comprises suspension fluid, first type charged particles, and second type charged particles. The first type charged particles and the second type charged particles are dispersed in the suspension fluid. Three cavities constitute a pixel unit. The first type charged particles and the second type charged particles in each of the three cavities constituting the pixel unit are one of red, green, and blue particles, and one of yellow, magenta, and cyan particles, respectively.
