Patent ID: 8324794

Claim:
A plasma display device comprising 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 of the substrates, 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 comprises a mixed phosphor containing a short persistence Mn 2+ -activated green phosphor with a 1/10 persistence time of more than 2 msec but less than 5 msec and either a Ce 3+ -activated green phosphor or an Eu 2+ -activated green phosphor that has a light emission peak in a wavelength range of not less than 490 nm and less than 560 nm.
