PROBLEM TO BE SOLVED: To obtain a plasma display panel of high quality and high definition in which occurrence of flickering and light-out due to impact and vibration is reduced. SOLUTION: In the plasma display panel, the rate of porosity of a phosphor layer is 23 to 37% or less. Thereby, even when chipping (breakage) of a partition wall occurs, scattering amount can be reduced and adhesion to the discharge electrode is reduced, and display failure such as flickering or light-out can be reduced.
