Abstract
A plasma display panel equipped with a front substrate and a back substrate facing each other to form a discharge space. On the discharge space side of the front substrate there are disposed a metal oxide layer and magnesium oxide crystal particles. The magnesium oxide crystal particles are arranged to be protruding closer to the discharge space than the surface of the metal oxide layer.
