Abstract: A plasma display panel in which a first substrate having a protective layer formed thereon opposes a second substrate across a discharge space, with the substrates being sealed around a perimeter thereof. At a surface of the protective layer, first and second materials of different electron emission properties are exposed to the discharge space, with at least one of the materials existing in a dispersed state. The first and second materials may be first and second crystals, and the second crystal may be dispersed throughout the first crystal.

Abstract: A technology effective for improving the luminous efficiency, lifetime, and color temperature of a PDP having phosphor layers of three colors is disclosed. A PDP comprises a plurality of narrow tubes (60) arrayed on a substrate (51). In each narrow tube (60), one of phosphor layers (61R, 61B, 61G) is formed and a discharge gas is contained. The compositions and pressures of the discharge gases are set within appropriate ranges respectively corresponding to the phosphor layers (61R, 61B, 61G). Consequently, the PDP can have a lengthened life-time and an improved luminous efficiency. Reductions of variation in breakdown voltage and adjustment of color temperature are also possible with this constitution.

Abstract: A plasma display panel having a dielectric protection layer (14) including MgO and phosphor layers (25R, 25G, 25B) for red, green, and blue respectively wherein none of the phosphor layers contain any member of the group consisting of Group IV elements, transition metals, alkali metals, and alkaline earth metals, or wherein all the phosphor layers each contain a specific amount of one or more members of the group consisting of Group IV group elements, transition metals, alkali metals and alkaline earth metals. In such a plasma display panel, changes over the course of time in the impedance of the dielectric protection layer (14) is suppressed, and the phosphor layers are uniform with respect to the directional characteristics of the changes of the impedances, which results in suppression of occurrence of black noise.
