Patent attributes
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, . . . , kth, . . . , nth voltage 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, kth voltage (absolute value) to be applied within kth voltage applying period, and 0V voltage, nth voltage (absolute value) to be applied within an nth voltage applying period. Relationships:|first applied voltage|>|kth applied voltage|>|nth voltage|and|first applied voltage|<|kth voltage|<|nth voltage|are satisfied.
