An electrophoretic display device includes a substrate and unit cells. Each of the unit cells has one display electrode, two collection electrodes and two types of charged particles different from each other in charged polarity and coloration, and has a driving means capable of forming a state in which each of the two types of charged particles have been collected respectively at each of the collection electrodes, a state in which one of the two types of charged particles have been disposed on the display electrode and the other type of charged particles have been collected at one of the collection electrodes, a state in which one of the two types of charged particles have been collected at one of the collection electrodes and the other type of charged particles have been disposed on the display electrode, and a state intermediate between these states. A color display device is provided which promises bright and sharp-color display and has a display quality level close to that of hard-copy representation mediums.
