ABSTRACT:
There is provided a display device including: an electrophoretic display element including, plural types of particles, each of the respective plural types of particles being charged with the same polarity, differing in optical properties, and differing in either in migration speed and/or electric field threshold value for moving, a translucent display-side electrode, a first back-side electrode, and a second back-side electrode; and a voltage control section that controls the voltages applied to the display-side electrode, the first back-side electrode, and the second back-side electrode, such that the types of particles having the fastest migration speed from the plural types of particles, or the types of particles having the lowest threshold value from the plural types of particles, are moved to the first back-side electrode or to the second back-side electrode, and then the particles that moved to the first back-side electrode are moved to the display-side electrode.
