Abstract: Provided is a plasma display apparatus having largely improved luminous efficiency while restraining cost increase of its driving circuit. A PDP 1 has an outer case formed by attaching a front panel 10 and a back panel 40, with barrier ribs 30 formed therebetween. Besides, a space created between the front panel 10 and the back panel 40 is filled with a rare gas such as Ne, Xe, and He. On the back panel 40, data-sustain electrodes 52 and data electrodes 51 are aligned alternately and parallel to each other. In a write period, a data driving circuit 4 performs selective data voltage output to the data electrodes 51 based on image data inputted for each subfield line by line. In a sustain period, a data-sustain driving circuit 5 performs collective data-sustain pulse application to the data-sustain electrodes 52.

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.
