ELECTRODE OF PLASMA DISPLAY PANEL AND ITS MANUFACTURE

PROBLEM TO BE SOLVED: To provide a plasma-display-panel electrode which can be fabricated by processes that are not complicated and which does not cause Ag to diffuse into a glass substrate during a baking process. SOLUTION: An electrode 9 provided on the front or back plate of a plasma display panel comprises an Ag-diffusion preventing layer 51 and an upper layer 56 provided thereon, which is made form a conductor material composed chiefly of Ag. A single metal or alloy with a melting point of 500 deg.C or higher is used in the diffusion preventing layer 51. The linear width of the diffusion preventing layer 51 is equal to or greater than that of the upper layer 56. During the process of forming the electrode, a glass substrate 2 does not show amber color even after baking process and therefore does not affect the image displayed on the panel.
