Plasma display and method of producing phosphor used therein

摘要

The present invention relates to a plasma display device and to a method of producing a phosphor to be used for the device, that prevents the phosphor layer from deteriorating, and improves the luminance, life, and reliability, of a plasma display panel (PDP). The plasma display device is equipped with a plasma display panel in which a plurality of discharge cells are arranged, phosphor layers ( 110 R, 110 G, 110 B) in color corresponding to each discharge cell are disposed, and phosphor layers ( 110 R, 110 G, 110 B) are excited by ultraviolet light to emit light. Green phosphor layer ( 110 G) has a green phosphor including Zn₂SiO₄:Mn, the element ratio of zinc (Zn) to silicon (Si) at the proximity of its surface is 2/1 , which is the stoichiometric ratio, and the layer is positively charged or zero-charged.
