Abstract
A method of manufacturing a plasma display panel, whose glass substrate is not tinged and luminance is high, is provided, even when silver material is used. A layer including silver compounds, which include sulfur generated on a surface of an electrode by reacting on sulfur in air, is removed before a forming process of a dielectric layer. Then decomposition of the compound is restricted in a firing process of the dielectric layer. Even when the electrode having the silver material with high electrical conductivity is used, yellow coloration on the glass substrate is prevented. As a result, a high quality plasma display panel which does not decrease in luminance is provided.
