METHOD OF PRODUCING PHOSPHOR USED IN PLASMA DISPLAYS

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 the 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 allocated, 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) is 2/1 to 2.09/1 at least at the proximity of the surface, and the layer is positively charged or zero-charged.
