Abstract
In the particles for display media used for an information display panel, in which at least one group of display media are sealed between two opposed substrates, at least one of two substrates being transparent, and, in which the display media, to which an electrostatic field is applied, are made to move so as to display information such as an image, a material having electric properties of a semiconductor is provided on a surface of the particles. According to the invention, since use is made of the particle whose surface has electric properties of a semiconductor, it is possible to maintain stably a surface charge of the particle for display media. As a result, it is possible to obtain an information display panel having a stable information display state such as an image.
