Abstract:
1. A plasma display panel comprising: a front substrate; a rear substrate facing the front substrate; a barrier rib that is positioned between the front substrate and the rear substrate and partitions a discharge cell; and a phosphor layer formed on the discharge cell, the phosphor layer including a first phosphor layer emitting first color light, a second phosphor layer emitting second color light, and a third phosphor layer emitting third color light, wherein the first phosphor layer includes a first pigment and first phosphor particles, and the second phosphor layer includes a second pigment and second phosphor particles, an average particle size of the second phosphor particles of the second phosphor layer is larger than an average particle size of the first phosphor particles of the first phosphor layer, and a proportion of the second pigment to the second phosphor particles in the second phosphor layer by weight is higher than a proportion of the first pigment to the first phosphor particles in the first phosphor layer by weight.
