Abstract:
1. A plasma display device having a panel main body, comprising: a first substrate; a second substrate, the first and second substrates facing each other so as to form a discharge space between the substrates; a barrier rib arranged on the first and second substrates to divide the discharge space into a plurality of discharge spaces; a first group of electrodes arranged on the first substrate; a second group of electrodes arranged on the second substrate, the first and second groups of electrodes arranged so as to generate discharge in the discharge spaces divided by the barrier rib; and a phosphor layer which emits light by discharge, wherein the phosphor layer is provided with a phosphor layer composed of green phosphor particles of negatively chargeable Zn and the ratio of an Mg element to an Si element on the surface of each of the green phosphor particles as measured by an XPS apparatus within 10 nm from an outermost surface of each of the green phosphor particles is not less than 0.7 nor more than 4.0.
