A plasma display panel (PDP) includes: a front substrate; a rear substrate disposed in opposition to the front substrate; first barrier ribs disposed between the front substrate and the rear substrate, defining discharge cells with the front substrate and the rear substrate, and formed of a dielectric material; front discharge electrodes disposed inside the first barrier ribs so as to surround the discharge cells; rear discharge electrodes disposed inside the first barrier ribs so as to surround the discharge cells, and spaced apart from the front discharge electrodes; phosphor layers disposed in the discharge cells; and a discharge gas deposited in the discharge cells. With respect to a longitudinal sectional view of the first barrier ribs, a virtual horizontal axis which extends from a lowermost portion of each of the rear discharge electrodes and is parallel to the front substrate intersects a lateral surface of the first barrier ribs at a certain position. An angle between a tangent line at the intersection of the horizontal axis and a lateral surface of the first barrier ribs, on one hand, and a virtual vertical axis orthogonal to the horizontal axis, on the other hand, ranges from 4.degree. to 17.degree..
