摘要： 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.

摘要： Inventions 1-3 relate to an image display unit provided with an image display plate for displaying an image formed by sealing at least two kinds of particles different in color and charging characteristic between two substrates, at least one of them being transparent, and imparting an electric field to particles from electrode pair consisting of electrodes provided on a substrate to move particles flying. In the first invention, fine recesses and/or fine protrusions (25) are provided on part of or whole of the surface of an electrode, or fine notched holes are provided on part of or whole of the surface of an electrode. In the second invention, the particle-contacting surface of a substrate is coated with a thin-film insulator having a volume resistivity of at least 1 × 1012 [Ω⋅cm] to provide a insulator thin film, or the arithmetic average roughness (Ra) and the unevenness average interval (Sm) of a particle-contacting substrate surface respectively satisfy specified expressions. In the third invention, a fly-moving current produced when particles in a pixel are moved flying is detected to thereby read an image display status.
