PLASMA DISPLAY PANEL, METHOD FOR PRODUCING SAME AND MATERIAL FOR PROTECTIVE LAYER OF SUCH PLASMA DISPLAY PANEL

摘要

A plasma display panel comprising a dielectric layer (9) which is so formed as to cover a scan electrode (5) and a sustain electrode (6) formed on a front substrate (4) and a protective layer (10) formed on the dielectric layer (9) is disclosed wherein the protective layer (10) contains silicon and nitrogen. The protective layer (10) is composed of magnesium oxide containing silicon at a concentration from 5 x 10<18> atoms/cm<3> to 2 x 10<21> atoms/cm<3> and nitrogen at a concentration from 1 x 10<18> atoms/cm<3> to 8 x 10<21> atoms/cm<3>. With this constitution, the plasma display panel has a short discharge delay and excellent discharge generation response to voltage application, and enables to suppress change of discharge delay to temperature change.
