摘要: PROBLEM TO BE SOLVED: To improve memory property in an image display medium that includes a plurality of types colored particles each having different threshold voltage necessary for moving accordance with electric field.SOLUTION: A control unit controls application such (particle-attached field) is applied magnitude does not cause attached to substrate at predetermined refresh interval move, and has polarity which generates force toward the least one type (colored low filed among particles) attached.
