Display medium particles in which micron particles are provided on the surface of a mother particle, and both the fluidity controllability and charging characteristics of the micron particles can be controlled at a high level, and the production thereof Methods and information display panels are provided. Information such as an image is moved by enclosing a display medium having optical reflectivity and chargeability between two substrates, at least one of which is transparent, and applying an electric field to the display medium. 2 or more types of micron particles 13-1 and 13-2 having different charging characteristics from each other are provided on the surface of the mother particle 12.
