PLASMA DISPLAY DEVICE AND PRODUCTION METHOD THEREFOR |
摘要 |
<p>A method of manufacturing a plasma display device which prevents the brightness of a phosphor layer from lowering is disclosed, and the method can form the phosphor layer in a stable manner because a nozzle is free from clogging. At least one of the phosphor layers has a green phosphor layer containing green phosphor having zero or positive charges and a crystal structure of Zn2SiO4:Mn. Green phosphor ink, of which major ingredient is the green phosphor, is applied through the nozzle to discharging cells, thereby forming the green phosphor layer. The green phosphor ink is formed of green phosphor powder coated with oxide having positive charges, or the ink is formed by crushing the green phosphor powder originally having negative charges and a crystal structure of Zn2SiO4:Mn such that the powder changes to have positive charges. <IMAGE></p> |
