PLASMA DISPLAY

摘要

A plasma display panel wherein all the charges are positive is disclosed which comprises a green phosphor which hardly adsorbs or reacts with water, carbon monoxide, a carbon dioxide gas or a hydrocarbon. As the green phosphor, there is used a mixed phosphor obtained by combining a green phosphor M1-xAl12O19:Mnx (wherein M is Ca, Sr, Eu or Zn) having a magnetoplumbite crystal structure and one or more phosphors selected from the phosphors having yttrium borate or yttrium aluminate crystal structure which are represented by the general formula (Y1-a-yGda)(Ga1-xAlx)3(BO3)4:Tby or (Y1-a-yGda)(Ga1-xAlx)3(BO3)4:Cey, Tby; the general formula (Y1-a-yGda)BO3:Tby; or the general formula (Y1-a-yGda)3(Ga1-xAlx)5O12:Tby.
