| 摘要 |
The present invention aims to drive a PDP at low voltage by providing a material with a high secondary electron emission coefficient under a practical manufacturing condition. In order to achieve the aim, a crystalline oxide selected from the group consisting of CaSnO3, SrSnO3, BaSnO3, and a solid solution of two or more of them, in which an amount of Ca, Sr or Ba in a surface region thereof is reduced, is used as a material for a protective film when a plasma display panel is produced.
