A method of manufacturing at least two layer electrodes that can be utilized, for example, as bus and data electrodes in a plasma display device, includes depositing each layer in a coating step and subsequently exposing the layers at the same time for development. The layers are subsequently baked at the same time. One layer can be thinner than the other layer during a time period between the developing step and the baking step.

Method of forming electrode layers

A manufacturing method for a metal electrode used for a bus electrode, a data electrode, and the like which make up a display panel including a PDP (Plasma Display Panel) by which, when these electrodes are patterned according to a photolithographic method, the edge curl phenomenon can be substantially controlled to the extent that the phenomenon is negligible. The manufacturing method of the invention therefore includes a dry step for drying the layers making up the metal electrode so that flows (F, F, and F) of the solvent occur from a region having a high absorbency of the solvent to a region having a lower absorbency of the solvent.

Multi-layered shaped electrode

To provide a technique for relatively easily preventing yellowing of a PDP that uses silver electrodes, and a PDP utilizing the technique that is capable of displaying images with high luminance and high quality. To form the electrodes, an alloy composed of Ag as a main constituent and a transition metal (at least one selected from Cu, Cr, Co, Ni, Mn, and Fe) is used, or an oxide of such a transition metal is added. Alternatively, an alloy composed of Ag as a main constituent and a metal (at least one selected from Ru, Rh, Ir, Os, and Re) is used, or an oxide of such a metal is added. Alternatively, Ag particles whose surfaces are each coated with a metal (Pd, Cu, Cr, Ni, Ir, or Ru) or a metal oxide (SiO, AlO, NiO, ZrO, FeO, ZnO, InO, CuO, TiO, or PrO) are used.

Plasma display panel and manufacturing method for the same

An object of the present invention is to provide a method for manufacturing electrodes that can effectively suppress edge-curl when metal electrodes such as bus electrodes and data electrodes are patterned mainly by a photolithography method. In order to achieve the above object, in the manufacturing method in the present invention, an amount of undercut generated by difference in a degree of dissolution caused by developing solution is controlled, and baking is performed at a temperature such that glass in a protrusion formed at side edges becomes soft so as to touch a substrate by gravity. With such method for manufacturing, it becomes possible to make the side edges rounded whose curvature changes continuously.
