PROBLEM TO BE SOLVED: To provide an information display panel capable of making the thickness of an insulation oxide film preferably as thick as 5μm or more, effectively suppressing image force acting on a particle, thereby reducing a driving voltage of the particle. SOLUTION: The information display panel displays information or the like by enclosing display medium between two sheets of substrates 1, 2 of which at least one side is transparent, applying a voltage between electrodes 5, 6 disposed on the substrates, providing an electric field to the display medium 3 and, thereby, moving the display medium, wherein the insulation oxide films 11, 12 comprising silicon oxide or zirconium oxide film formed by sputtering are formed on the surface of an electrode made of metal oxide of the electrodes.
