Abstract

A plasma display device including a green phosphor of which brightness is hardly deteriorated and a production method therefore are disclosed. The plasma display device comprises a plasma display panel in which a plurality of discharge cells of one color or a plurality of colors are disposed, red phosphor layers 110R, green phosphor layers 110G, and blue phosphor layers 110B are arranged correspondingly to the respective discharge cells, and the red phosphor layers 110R, the green phosphor layers 110G, and the blue phosphor layers 110B are excited by ultraviolet rays to emit light. The green phosphor layers 110G include a green phosphor expressed by (Ma-x-yEuxTby)O.MgO.2SiO2 (here, M is at least one element selected from Ca, Sr, and Ba).
