    • A high-quality long-life plasma display panel is provided by enabling compatibility between priming-electron emission characteristics, and other characteristics such as sputtering resistance, secondary electron emission characteristics, and wall charge retention. The plasma display panel is structured to include a front substrate, transparent electrodes and bus electrodes provided on the inner side of the front substrate, a dielectric layer covering these electrodes, a first protective layer covering the dielectric layer, and a second protective layer disposed on the side closer to the discharge space than the first protective layer. The first protective layer is doped with Sc to generate a predetermined excitation light by incidence of ultraviolet light. The second protective layer is doped with Si to emit electrons to the discharge space by the excitation light. With this structure, it is possible to realize a plasma display device in which the discharge delay is small, thereby the fluctuation less occurs.
    • 通过实现引发电子发射特性和诸如溅射电阻,二次电子发射特性和壁电荷保留的其它特性之间的兼容性,提供了高质量的长寿命等离子体显示面板。 等离子体显示面板被构造为包括前基板,设置在前基板的内侧的透明电极和总线电极,覆盖这些电极的介电层,覆盖电介质层的第一保护层和设置在电介质层上的第二保护层 比第一保护层更靠近放电空间的一侧。 第一保护层掺杂有Sc以通过紫外光的入射产生预定的激发光。 第二保护层掺杂有Si以通过激发光向放电空间发射电子。 利用这种结构,可以实现放电延迟小的等离子体显示装置,从而发生波动较小。
