Abstract

In the information display panel, in which one or more groups of display media are sealed between opposed two substrates, at least one substrate being transparent, and, in which the display media, to which an electrostatic field generated between the substrates is applied, are made to move so as to display information such as an image, at least one substrate of the two substrates (both substrates in the figure) is a laminated substrate in which a first substrate, a low elastic layer and a second substrate are successively laminated from an outer surface, so that a stress concentration at a rib adhesion portion and so on of a partition wall can be reduced, If the laminated substrate with a laminated construction including a buffer layer for reducing stress concentration, it is possible to provide the information display panel, which can improve a mechanical strength with respect to an external force.
