A PDP includes a front panel including display electrode (6) formed on glass substrate (3), dielectric layer (8) covering display electrode (6), and protective layer (9) formed on dielectric layer (8); and a rear panel opposing to the front panel to form a discharge space filled with discharge gas, and including an address electrode formed along a direction intersecting with display electrode (6), and a barrier rib partitioning the discharge space, wherein protective layer (9) is formed of a metal oxide made of magnesium oxide and calcium oxide and contains aluminum, and a diffraction angle where a peak of the metal oxide occurs exists between a diffraction angle where a peak of the magnesium oxide occurs and a diffraction angle where a peak of the calcium oxide occurs in an X-ray diffraction analysis on a surface of protective layer (9).

Provided is a manufacturing method that allows even a PDP having high-definition cells to exhibit excellent image display performance with reduced power consumption by effectively preventing impurities from adhering to the protective layer. Specifically, in a pre-baking step, a back substrate 9 is baked at a pre-baking temperature. Here, a highest pre-baking temperature is set to be lower than a softening point of a sealing material. The back substrate 9 is superposed on a front substrate 2. Then, a sealing step is performed in a sealing atmosphere prepared by mixing a predetermined amount of a reducing gas with a non-oxidizing gas. The above enables the impurities attributed to organic components due to a sealing material paste to remain as low molecular components, whereby the impurities are evacuated and removed in an evacuating step performed after the sealing step. This prevents adherence of the impurities to the protective layer 8.

The surface of a rear substrate formed by a rear glass / rear dielectric layer / partition is uniformly coated with a non-volatile oxide adsorption layer. The surface of the non-volatile oxide adsorption layer is formed with a phosphor layer.

To achieve the aim, deterioration of an absorbent material 39 composed of copper ion-exchanged ZSM-5-type zeolite is prevented, by performing both sealing and evacuation steps for the front substrate 2 and back substrate 9 in a non-oxidizing gas atmosphere. This maintains properties of the absorbent material 39 for absorbing the impurity gas without degradation, even if the absorbent material 39 absorbs a Xe gas in a discharge gas introducing step.
