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： In a panel unit of a PDP apparatus, a discharge space is filled with a discharge gas containing a xenon gas as a principal component and a neon gas at a total pressure in a range of 1×104 [Pa]-5×104 [Pa], inclusive. Since the discharge gas is a xenon-neon binary gas mixture, when a partial pressure ratio of the neon gas to the total pressure ratio of the discharge gas is set at 8[%] or below, the rest of the discharge gas is the xenon gas, the principal component. In summary, the PDP apparatus of the present invention can attain high luminous efficiency with use of the high xenon gas content, and suppress erosion of a protective layer as a result of sputtering caused by a discharge during driving with use of the neon gas whose partial pressure ratio is 8[%] or below.

摘要： A PDP capable of lowering a discharge initiating voltage with a weak discharge always stabilized during an initialization period even if a Xe partial pressure ratio to a total pressure in discharge gas is increased, improving an image quality with the occurrence of an initializing bright point prevented, preventing the lowering of a light emission efficiency and brightness, and improving brightness; and a production method for simply producing the PDP. The PDP comprises a front panel and a rear panel disposed facing each other with a discharge space provided between them. A fluorescent layer is formed in the area on the discharge space side of the rear panel, and a fluorescent film as a high γ portion is formed in part of the area of its surface. The fluorescent film is formed of a material higher in secondary electron emission coefficient γ than a fluorescent material constituting the fluorescent layer. Part of the surface of the fluorescent layer is covered with the fluorescent film, with the other part facing the discharge space.
