    • The present invention provides a plasma display device that has light emission properties with short persistence where green light has a persistence time of 3.5 msec or less, that is excellent in luminance, luminance degradation resistance, and color tone, and that is suitable for, for example, a stereoscopic image display device. The present invention provides a plasma display device including a plasma display panel in which a pair of substrates at least whose front side is transparent are disposed to oppose each other so as to form a discharge space between the substrates, barrier ribs for dividing the discharge space into a plurality of discharge spaces are disposed on at least one substrate, electrode groups are disposed on the substrates so as to produce discharge in the discharge spaces divided with the barrier ribs, and a green phosphor layer that emits light by the discharge is provided, wherein the green phosphor layer includes a mixed phosphor containing a short persistence Mn2+-activated green phosphor with a 1/10 persistence time of more than 2 msec but less than 5 msec and either a Ce3+-activated green phosphor or an Eu2+-activated green phosphor that has a light emission peak in a wavelength range of not less than 490 nm and less than 560 nm.
    • 本发明提供一种具有短持续时间的发光特性的等离子体显示装置,其中绿光的持续时间为3.5msec以下,亮度,亮度劣化电阻和色调优异,适用于 例如,立体图像显示装置。 本发明提供一种等离子体显示装置,其包括等离子体显示面板,其中至少其前侧是透明的一对基板彼此相对设置,以便在基板之间形成放电空间,隔离肋用于分隔放电空间 在至少一个基板上设置多个放电空间,电极组设置在基板上,以在与隔壁分隔的放电空间中产生放电,并且提供通过放电发光的绿色荧光体层, 其中,所述绿色荧光体层包含含有持续时间短于2毫秒但小于5毫秒的1/10持续时间的短持续性Mn2 +活化绿色荧光体的混合荧光体,以及Ce 3+活化的绿色荧光体或Eu 2+激活的绿色荧光体 其波长范围不小于490nm且小于560nm具有发光峰。
