Abstract
An image display device expresses multiple colors including intermediate colors and an electrophoretic particle making up the image display device includes n-kinds of (n>2) charged particles each having colors and threshold value voltages each being different from one another. A specified period during which a voltage is applied includes a resetting period for applying a resetting voltage, a first, . . . , k, . . . , nvoltage applying periods and a voltage to be applied includes a resetting voltage, 0V, first voltage (absolute value) to be applied within the first voltage applying period, 0V, kvoltage (absolute value) to be applied within kvoltage applying period, and 0V voltage, nvoltage (absolute value) to be applied within an nvoltage applying period. Relationships:|first applied voltage|>|applied voltage|>|voltage|and|first applied voltage|<|voltage|<|voltage|are satisfied.
