Abstract
An image display medium comprising a pair of substrates, at least one of which is light-transmissive; two or more kinds of particles having different colors and charge polarities, the particles being positioned between the pair of substrates such that the particles can move in response to an electric field generated between the pair of substrates; and an electric charge-retention layer provided at a side of at least one of the pair of substrates.

An image display device including:
- an image display medium comprising
- a pair of substrates, at least one of which is light-transmissive,
- two or more kinds of particles having different colors and charge polarities, the particles being positioned between the pair of substrates such that the particles can move in response to an electric field generated between the pair of substrates, and
- an electric charge-retention layer provided at a side of at least one of the pair of substrates;
- a storage unit that stores information regarding threshold voltage characteristics of the two or more kinds of particles;
- and
- a voltage-application unit that sets a voltage to be applied corresponding to inputted image data based on the information regarding the threshold voltage characteristics stored in the storage unit, and applies a voltage between the pair of substrates of the image display medium.
