Abstract
In an information display panel, in which one or more groups of display media having light reflectance and charge characteristic, constituted by at least one group of particles, are sealed between opposed 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, in order to seal a space between one substrate and the other substrate, a gap-space maintaining member is formed at either one or both of an outer side and an inner side with respect to a sealing-agent arranging portion arranged at an outer peripheral portion of an information display region of the panel.

An information display panel, in which one or more groups of display media having light reflectance and charge characteristic, constituted by at least one group of particles, are sealed between opposed 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, characterized in that, in order to seal a space between one substrate and the other substrate, a gap-space maintaining member is formed at either one or both of an outer side and an inner side with respect to a sealing-agent arranging portion arranged at an outer peripheral portion of an information display region of the panel,
- wherein in the case of forming the gap-space maintaining member as a continuous member, the gap-space maintaining member is formed by a construction or a material, which allows a gas transmitting function;
- and
- gas is discharged from the display region through a space in the sealing-agent arranging portion and through the gap-space maintaining member.
