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.

摘要： Each embodiment relates to an image display device which comprises an image display panel, in which two or more groups of particles having different colors and different charge characteristics are sealed between two substrates, at least one of two substrates being transparent, and, in which the particles, to which an electrostatic field produced by a pair of electrodes provided on one or both substrates is applied, are made to fly and move so as to display an image. Among them, in the first aspect of the invention, an image forming process for forming the image by applying an electric field pattern between the electrodes, the electric field pattern serving to fly particles A to the substrate at an image display side; and an image forming process for forming the image by applying an inversion (negative) electric field pattern with respect to the electric field pattern, the inversion electric field pattern serving to fly particles B having different colors and different charge characteristics with respect to those of the particles A to the substrate at an image display side; so that an image deleting process prior to forming the image to be displayed is eliminated.

摘要： An image display device according to first to third aspects of the invention has an image display panel, in which two or more groups of particles having different colors and different charge characteristics are sealed between two substrates, at least one of two substrates being transparent, and, in which the particles, to which an electrostatic field produced by a pair of electrodes provided on respective substrates is applied, are made to fly and move so as to display an image. In the first aspect of the invention, micro-concave portions and/or micro-convex portions are provided to a part of or an overall of a surface of the electrode (first embodiment) or micro-cutout holes are provided to a part of or an overall of a surface of the electrode (second embodiment). Moreover, in the second aspect of the invention, an insulation member having a volume resistance of not less than 1×10 12 [Ω·cm] is coated thinly on a surface of the substrate to which the particles are contacted so as to provide a thin insulation film, or, an arithmetic average roughness (Ra) and a concave-convex average distance (Sm) of a surface of the substrate, to which the particles are contacted, satisfy the predetermined formulas. Further, in the third aspect of the invention, an image display state is read-out by detecting a fly/move current produced when the particles are flown and moved in a pixel.
