PLASMA DISPLAY PANEL AND ITS MANUFACTURING METHOD

摘要

Provided is a PDP capable of exhibiting electric charge holding characteristic in a protection layer while driving the PDP with a low voltage and exhibiting a preferable image display characteristic. Moreover, in addition to the aforementioned effects, it is possible to prevent generation of discharge delay and preferably perform high-speed drive even in a highly fine PDP, thereby realizing a high-quality image display. As means for realizing this, a surface layer (8) formed under an oxygen atmosphere of oxygen partial pressure of 0.025 Pa or above and having a film thickness of about 1 µm is arranged on the discharge space side of a dielectric layer (7). Furthermore, on the surface of the surface layer (8), MgO minute particles (16) are dispersed. The surface layer (8) protects the dielectric layer (7) from ion bombardment during discharge, reduces the discharge start voltage, and improves the charge missing. Moreover, the MgO minute particles (16) exhibit a high initial electron emission characteristic.
