PROBLEM TO BE SOLVED : To provide a plasma display panel which can perform excellent image display at a low voltage.
SOLUTION : A plasma display panel comprises : a pair of substrates 21 and 31 arranged to face each other via a space, on which electrodes 24 and 32 for generating discharge are formed on respective inner surfaces; a dielectric layer 26 covering the electrode 24 formed on the one substrate 21 between the pair of substrates 21 and 31; and a protection film 27 covering the dielectric layer 26. The protection film 27 is formed from any one of a calcium oxide, a strontium oxide, a barium oxide and a rare earth oxide, or a mixture of a calcium oxide, a strontium oxide, a barium oxide and a rare earth oxide. The protection film 27 includes tungsten of 5 atm% or more to 30 atm% or less.
