Abstract:
A display panel, comprisinga first panel, which includes a substrate, a plurality of electrodes in rows on one main surface of the substrate, and a dielectric layer formed so as to cover the rows of electrodes; and a second panel, which is parallel to and joined by a gap material to the first panel, wherein the substrate is made of a material containing glass, and the electrodes are made of a material containing silver, and the ratio of concentration of diffused silver in the dielectric layer, measured in an area with a diameter of 5 &mgr;m centered 5 &mgr;m from an interface of a main surface of each electrode and the dielectric layer (P3), versus concentration of diffused silver measured in an area of the substrate with a diameter of 5 &mgr;m centered 7.5 &mgr;m from the interface of the electrode and the substrate (P1), is 0.5 or less.
