摘要： Protective layer (26) of front plate (20) of a plasma display panel has base protective layer (26a) and particle layer (26b). Base protective layer (26a) is formed of a thin film of metal oxide containing at least one of magnesium oxide, strontium oxide, calcium oxide, and barium oxide. Particle layer (26b) is formed by sticking, to base protective layer (26a), single crystal particles (27) of magnesium oxide having an NaCl crystal structure that is surrounded by a specified two-type orientation face formed of (100) face and (111) face or a specified three-type orientation face formed of (100) face, (110) face, and (111) face. The panel driving circuit drives the panel while temporally disposing the subfields so that the luminance weight monotonically decreases from a subfield in which an all-cell initializing operation is performed to the subfield immediately before the subfield in which its next all-cell initializing operation is performed.

摘要： 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.

摘要： “Discharge delay” and “dependence of discharge delay on temperatures” are solved by improving a protective layer, thus a PDP can be driven at a low voltage. Furthermore, the PDP can display excellent images by suppressing “dependence of discharge delay on space charges.” Liquid-phase magnesium alkoxide (Mg(OR)2) or acetylacetone magnesium ate whose purity is 99.95% or more is prepared, and is hydrolyzed by adding a small amount of acids to the solution. Thus, a gel of magnesium hydroxide that is a magnesium oxide precursor is formed. Burning the gel in atmosphere at 700° C. or more produces powder containing MgO particles 16a-16d having the NaCl crystal structure with (100) and (111) crystal faces or with (100), (110) and (111) crystal faces. By pasting the powder on a dielectric layer 7 or a surface layer 8, the MgO powder 16 is formed so as to serve as the protective layer.

摘要： A plasma display panel demonstrating excellent image display performance by suppressing generation of initialization bright points through modification of the phosphor layer, and by eliminating variation in discharge characteristics between the discharge cells of each color. In addition to solving these problems, the luminance of the plasma display panel is also enhanced by using the ultraviolet rays emitted in the discharge space in order to promote the production of visible light on the front panel side. Specifically, the phosphor layer (14) is composed of a phosphor component and of MgO powder (16) disposed principally inside the phosphor layer and exposed towards the surface (140) facing the discharge space in order to impart secondary electron emission characteristics. The MgO powder (16) is composed of MgO particles (16a-16d) having a crystal structure with two specific crystal faces consisting of the (100) crystal face and the (111) crystal face, or three specific crystal faces consisting of the (100) crystal face, the (110) crystal face, and the (111) crystal face.

摘要： A PDP can be driven at low voltage while having a charge retention property in a protection layer, and has favorable image display properties. Additionally, the PDP prevents the occurrence of discharge delay and realizes high-quality image display by performing favorable high-speed driving in a high definition PDP. To achieve this, a surface layer (8) is formed to a film thickness of 1 μm in an oxygen atmosphere having an oxygen partial pressure of 0.025 Pa or more, the surface layer (8) is provided on a face of a dielectric layer (7) on a discharge space side. Furthermore, MgO particles (16) are dispersed on a surface of the surface layer (8). The surface layer (8) has the effects of protecting the dielectric layer (7) from ion bombardment during discharge, reducing the firing voltage, and preventing excessive electron loss. Also, the MgO particles (16) have a high initial electron emission property.
