<p>A plasma display panel more excellent in discharge stability than conventional ones. An intermediate layer for enhancing the orientation of a columnar crystal constituting a protection layer is provided to ensure the above feature when the protection layer is formed on a dielectric layer. Accordingly, a selectively oriented columnar crystal formed on the intermediate layer and its diameter formed to be larger than conventional ones can reduce the exposed area of the entire protection layer to below conventional ones and the amounts of impurities adsorbed to the protection layer. As a result, the releasing amounts of impurities adsorbed to the columnar crystal during PDP discharging can be restrained to thereby improve PDP discharge characteristics.</p> |
