Abstract
In the method of manufacturing an information display panel, in which at least one group of display media having optical reflectance and charge characteristics and consisting of at least one or more groups of particles, are sealed in a cell formed by partition walls between two substrates, at least one substrate 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 display media filling step for filling the display media in the cell includes the steps of: setting a screen over the partition walls; arranging the display media on the screen; and moving a plate member on the screen under such a condition that the plate member is contacted to the screen. In this manner, it is possible to obtain the method of manufacturing the information display panel in which it is possible to fill the display media by an easy process, and to make easy a control of an area, to which the display media are to be filled, and a control of an amount of the display media to be filled.
