Plasma-display panel

A plasma display panel comprising:

• a front substrate;
• a rear substrate opposing the front substrate to form a discharge space therebetween;
• barrier ribs disposed on the rear substrate to partition the discharge space into a plurality of sections;
• and
• a phosphor layer disposed between the barrier ribs,
• wherein the phosphor layer comprises a green phosphor layer containing Zn2SiO4:Mn particles, and (Y1-x, Gdx)3(Al1-y, Gay)5O12:Ce particles wherein 0≦x≦1, and 0≦y≦0.5, and
• the Zn2SiO4:Mn particles satisfy the following requirements (1) and (2):
• Zn3p/Si2p≧2.10 (1)
• Zn2p/Si2p≧1.25 (2)
• where Zn3p is an emission amount of photoelectrons emitted from a 3p orbit of a Zn element in a region up to 10 nm from surfaces of the particles,
• Zn2p is an emission amount of photoelectrons emitted from a 2p orbit of the Zn element in a region up to 3 nm from the surfaces of the particles, and
• Si2p is an emission amount of photoelectrons emitted from a 2p orbit of a Si element in the region up to 10 nm from the surfaces of the particles.
