ABSTRACT:
A plasma display device provided with a green color phosphor which is charged entirely with a positive potential, adsorbs only limited amounts of water, carbon monoxide, carbon dioxide and hydrocarbon, and not liable to cause chemical reaction thereto. The green color phosphor used is a combination of any of phosphors defined by the general formula of MMg1-xAl11O19:Mnx(where “M” denotes one of La and Ce) having a magnetoplumbite crystal structure, yttrium borate group and yttrium aluminate group phosphors defined by the general formulae of (Y1-a-yGda) BO3:Tby, (Y1-a-yGda) (Ga1-xAlx)3(BO3)4:Tby, (Y1-a-yGda) (Ga1-xAlx)3(BO3)4:Cey, Tby, (Y1-y)3(Ga1-xAlx)5O12:Tbyand La Mg1-xAl11O19:Cex, Tbx.
