PLASMA DISPLAY PANEL

摘要

Disclosed is a plasma display panel provided with a front panel (2), and a back panel (10) which is disposed facing the front panel (2). The front panel (2) has: display electrodes (6); a dielectric layer (8) which covers the display electrodes (6); and a protective layer (9) which covers the dielectric layer (8). The protective layer (9) comprises an underlayer (91) formed on the dielectric layer (8), and a plurality of particles distributed on the underlayer (91). The underlayer (91) has magnesium oxide nanocrystal particles having an average particle diameter between 10nm and 100nm inclusive. The particles are aggregates (92) in which a plurality of metallic oxide crystal particles are aggregated. The average particle diameter of the aggregates (92) is between two and four times inclusive that of the film thickness of the underlayer (91).
