Abstract: A technology effective for improving the luminous efficiency, life time, 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. Reduction of variation in breakdown voltage and adjustment of color temperature are also possible with this constitution.

Abstract: A plasma display panel comprises a first substrate on which plural pairs of display electrodes, each pair being composed of a first electrode and a second electrode, are arranged generally in parallel, and a second substrate opposing to the first substrate on which third electrodes are disposed in a direction perpendicular to the longitudinal direction of the display electrodes and partitions are formed between two adjacent third electrodes. The plasma display panel is characterized in that a fourth electrode electrically exposed to discharge spaces defined with the partitions is formed on the partitions or on the surface of the first substrate opposing to the partitions in the vicinity of adjacent display electrodes.
