Abstract
A plasma display panel (PDP) includes a front panel including (i) a substrate, (ii) a display electrode formed on the substrate, (iii) a dielectric layer formed to cover the display electrode, and (iv) a protective layer formed on the dielectric layer. Further, the PDP includes a rear panel disposed facing the front panel forming a discharge space, and including an address electrode formed in a direction intersecting the display electrode and a barrier rib partitioning the discharge space. The protective layer is formed by forming a base film of MgO on the dielectric layer and attaching a plurality of aggregated particles of metal oxide crystal particles to the base film so that the aggregated particles are distributed over the entire surface, the base film includes Si as a material impurity, and a Si concentration in the base film is more than 0 ppm and not more than 10 ppm.
