US 2009/0153050 A1 · PLASMA DISPLAY PANEL

Abstract

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.
