Abstract:
The present invention provides display device particles that have positive or negative chargeability and have color and are produced using at least a calcium compound, in which a concentration of the calcium compound in the display device particle is 0.05% by weight or less in terms of a calcium element content, a process for producing the display device particles, as well as an image-display medium and an image-forming device each using the display device particles.
