Abstract
A display medium includes a light control layer, wherein the light control layer includes mobile fine particles developing a color in a dispersion state and hetero-particles having characteristics different from those of the mobile fine particles. A display method includes at least one of the following steps: a step of displaying black color by allowing the mobile fine particles capable of developing a color in a dispersion state to aggregate; a step of displaying a color by allowing the mobile fine particles to disperse; or a step of displaying white color by reflection of the hetero-particles having characteristics different from those of the mobile fine particles.
