Patent ID: 7495819

Claim:
A method of manufacturing an image display device which comprises an image display panel having one or more image display cells isolated from each other by partition walls, in which two kinds of liquid powders composed of a solid material stably floating as a dispersoid in a gas and exhibiting a high fluidity in an aerosol state, having a pale bright color and a deep dark color and having different charge characteristics, or, two kinds of particles having a pale bright color and a deep dark color and having different charge characteristics, are sealed between a transparent substrate and an opposed substrate, and, in which the liquid powders or the particles, to which an electrostatic field produced by a pair of electrodes having different potentials is applied, are made to fly and move so as to display a monotone image, wherein the method comprises: filling an amount of the liquid powders or the particles in spaces constituting the image display cells isolated by the partition walls; removing unnecessary liquid powders or unnecessary particles remaining on the partition walls in the filling; stacking the transparent substrate and the opposed substrate via the partition walls and applying a sealing agent at a peripheral portion of the substrate so as to make an atmosphere between the transparent substrate and the opposed substrate uniform; and connecting a circuit for displaying the image to the electrode so as to form a module, wherein an apparent volume in a maximum floating state of the liquid powders is two times or more than that in non-floating state.
