    • The present invention aims to provide a plasma display panel that can be driven at low voltage and can offer favorable image display performance. In order to achieve the aim, on a surface of the front panel 1 on which the display electrode 5 is formed, the protective layer 7 made by using a crystalline oxide material that contains a crystalline oxide selected from the group consisting of (i) at least one of SrCeO3 and BaCeO3 and (ii) a solid solution of SrCeO3 and BaCeO3 is disposed so as to face the discharge space 14. By using the crystalline oxide material that contains the crystalline oxide selected from the group consisting of (i) at least one of SrCeO3 and BaCeO3 and (ii) a solid solution of SrCeO3 and BaCeO3, chemical stability can be improved without reducing secondary electron emission efficiency. A PDP capable of lowering drive voltage compared with a case where MgO is used can be obtained by using the crystalline oxide material.
    • 本发明的目的在于提供一种能够以低电压驱动的等离子体显示面板,能够提供良好的图像显示性能。 为了达到目的,在其上形成有显示电极5的前面板1的表面上,使用包含选自以下的结晶氧化物的结晶氧化物材料制成的保护层7:(i) 将SrCeO 3和BaCeO 3中的至少一种和(ii)SrCeO 3和BaCeO 3的固溶体设置成面对放电空间14.通过使用含有选自以下的结晶氧化物的结晶氧化物材料:(i)至少 SrCeO3和BaCeO3之一,(ii)SrCeO3和BaCeO3的固溶体,可以提高化学稳定性,而不会降低二次电子发射效率。 通过使用结晶性氧化物材料,可以得到与使用MgO的情况相比能够降低驱动电压的PDP。
