PLASMA DISPLAY PANEL

摘要

Disclosed is a plasma display panel (1) 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) which is formed on the dielectric layer (8); and aggregates (92) which are dispersed across the complete surface of the underlayer (91) and in which a plurality of metal oxide crystal particles (92a) are aggregated. The underlayer (91) comprises MgO, Ce, and Ge. The concentration of Ce in the underlayer (91) is between 200ppm and 500ppm inclusive, and the concentration of Ge is between 100ppm and 5000ppm inclusive.
