Abstract:
Provided is a high-efficiency plasma display panel having short decay time and high luminance and color purity. The plasma display panel includes a green phosphor layer emitting visible light when excited with vacuum ultraviolet rays, in which the green phosphor layer is formed of a green phosphor containing 30% by weight or more and 60% by weight or less of a phosphor represented by a general formula: dZnO.(2−d)MnO.eSiO2 (1.80≦d≦1.90, 1.00≦e≦1.02) and one of a phosphor represented by a general formula: aYO3/2.(3−a)CeO3/2.bAlO3/2.cGaO3/2.fWO3 (2.80≦a≦2.99, 3.00≦b≦5.00, 0≦c≦2.00, 0.003≦f≦0.020, where 4.00≦b+c≦5.00) and a phosphor represented by a general formula: aYO3/2.(3−a)CeO3/2.bAlO3/2.cGaO3/2.gK2WO4 (2.80≦a≦2.99, 3.00≦b≦5.00, 0≦c≦2.00, 0.003≦g≦0.015, where 4.00≦b+c≦5.00).
