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 first aim of the present invention is to provide a PDP capable of stably delivering favorable image display performance and being driven with low power, by improving the surface layer to improve secondary electron emission characteristics and charge retention characteristics. A second aim of the present invention is to provide a PDP, in addition to having the above-mentioned effects, capable of reducing an aging time. In order to achieve these aims, a crystalline film of a film thickness of approximately 1 μm is disposed as a surface layer (protective film) 8 on a surface of the dielectric layer 7 that faces a discharge space. The surface layer 8 is made by adding Sr to CeO2, and a concentration of Sr in the surface layer 8 is in a range of 11.8 mol % to 49.4 mol % inclusive. With this structure, an attempt is made to improve the secondary electron emission characteristics and aging characteristics in the surface layer 8.
