Abstract
A plasma display panel (PDP) and a method of manufacturing the same suppresses variation in the height of the intersecting barrier walls with a simple method and that prevents cross talk from occurring between the discharge cells. A concave part is formed at a position contacting an intersecting part of a first barrier wall before baking and a second barrier wall before baking orthogonal to the first barrier wall before baking. When such concave part is formed, the values of the surface area per volume of the intersecting part and the surface area per volume of the first barrier wall before baking and the second barrier wall before baking between the intersecting part and the intersecting part adjacent to the intersecting part become substantially equal. As a result, the height of the intersecting part does not become high after baking, a barrier wall of aligned height is obtained, and cross talk does not occur between the discharge cells.
