Patent ID: 7973477

Claim:
A plasma display panel including a first substrate and a second substrate arranged to face each other with a space therebetween, and including a phosphor layer in an area of the first substrate that faces toward the space, wherein part of a surface of the phosphor layer is covered with a high gamma member that is made of a material having a higher secondary electron emission coefficient than a material of the phosphor layer, and the high gamma member and a remaining area of the surface of the phosphor layer are exposed to the space, wherein the space that exists between the first substrate and the second substrate has been filled with a discharge gas that contains Xe, and a ratio of a partial pressure of Xe to a total pressure of the discharge gas is in a range of 5% to 100% inclusive, wherein a coverage ratio of the high gamma member to the surface of the phosphor layer is in a range of 3% to 20% inclusive.
