| 简介 |
Disclosed is a plasma display panel that can be expected to show excellent image display performance while requiring relatively low driving voltage. To this end, a chemical compound containing one or more rare earth metals, Sn, and oxygen is distributed as an electron emitting material (compound powders (20)) over a surface of a protective layer (7) facing a discharge space (14) in a PDP (200). The distributed compound is desirably a crystalline compound so that the stability thereof is increased. The crystalline compound includes Ln2Sn2O7 phase (Ln can include only one rare earth metal, or can include a plurality of rare earth metals). With this, an excellent secondary electron emission characteristic can be exhibited during driving, and the driving voltage of the PDP (200) can be reduced. |
