    Abstract: 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.

    Abstract: The semiconductor light emitting device is composed of a combination of a near ultraviolet LED and a phosphor layer including a plurality of phosphors for absorbing near ultraviolet emitted by the near ultraviolet LED and for emitting fluorescence having an emission peak in a visible wavelength region, and the phosphor layer includes four kinds of phosphors, that is, a blue-based phosphor, a green-based phosphor, a red-based phosphor and a yellow-based phosphor. Thus, lowering of luminous flux derived from red-based light with low luminosity is compensated by yellow-based light with comparatively high luminosity, and the resultant white-based light can be well color balanced, and hence, a semiconductor light emitting device emitting white-based light with high luminous flux and a large Ra can be obtained.
