PLASMA DISPLAY PANEL-USE PROTECTION FILM AND PRODUCTION METHOD FOR THE PROTECTION FILM, PLASMA DISPLAY PANEL AND PRODUCTION METHOD THEREFOR

摘要

A plasma display panel (1), wherein a protection film (14) on a maintaining electrode (15) and a scanning electrode (16) mainly contains both CaO and SrO, and the concentration of CaO in the protection film (14) is set to 20mol% through 90mol%. Since such a protection film (14) has a smaller work function than that of a conventional MgO film, light emission is possible with a discharge voltage lower than before. A lower discharge voltage can slow a speed at which the protection film (14) is sputtered to thereby enable the life of the plasma display panel (1) to be longer. In addition, Xe gas contained in the plasma gas can increase the luminance of the plasma display panel.
