PURPOSE: A plasma display panel is provided to achieve improved efficiency by arranging an electrode between discharge sustain electrodes. CONSTITUTION: A plasma display panel comprises a first substrate(20) and a second substrate(22) arranged substantially parallel with each other with a spacing formed between the first and second substrates; a plurality of address electrodes(26) formed on the first substrate; a dielectric layer(24) formed all over the first substrate in such a manner that the address electrodes are covered with the dielectric layer; a plurality of barrier ribs(34) arranged upright to have predetermined heights on the dielectric layer, and which form discharge spaces(36); phosphor layers(38) formed in the discharge spaces; a plurality of discharge sustain electrodes(30) disposed on the surface of the second substrate opposed to the first substrate, in such a manner that the discharge sustain electrodes are perpendicular to the address electrodes; a dielectric layer(28) formed all over the second substrate in such a manner that the discharge sustain electrodes are covered by the dielectric layer; a discharge gas injected into the discharge spaces; and an efficiency improvement electrode(40) formed between the discharge sustain electrodes, and which has a width maintained at 30 to 50% of the gap formed between the discharge sustain electrodes. |
