ABSTRACT:
A plasma display device has a panel main body in which a pair of transparent substrates is arranged in opposition so as to form a discharge space between the substrates on at least a front side. Barrier ribs are arranged on at least one of the substrates to divide the discharge space into a plurality of spaces. A group of electrodes is arranged on the substrates so as to generate discharge in the discharge space divided with the barrier ribs. Phosphor layers that emit by discharge are also provided. The phosphor layers are equipped with a green phosphor layer including at least Zn2SiO4:Mn, a surface of Zn2SiO4:Mn is coated with aluminum oxide, and a ratio of an Al element to a Si element on the surface measured with an XPS apparatus is 0.6 to 4.0.
