ABSTRACT:
A high-luminance plasma display panel has a plurality of discharge cells including a phosphor film emitting visible rays by excitation caused by ultraviolet light generated by the discharge of a discharge gas. The phosphor film has at least two layers of a phosphor layer and a reflecting layer, and the phosphor layer is arranged closer to the discharge space side than the reflecting layer. A film thickness Wt of the phosphor film is 40 μm or less, and a film thickness Wp of the phosphor layer, a particle diameter dp of a phosphor that is at least a part of components of the phosphor layer, a film thickness Wr of the reflecting layer, and a particle diameter dr of a reflecting material that is at least a part of components of the reflecting layer satisfy 2dp≦Wp≦5dp and 2dr≦Wr≦Wt−Wp.
