Abstract
A fluorine-containing precoating is formed to cover a phosphor particle by, for example, a physical vapor deposition of a fluoride. Then, a fluorine-containing coating covering the phosphor particle is formed by supplying fluorine into the precoating. This obtained phosphor particle with the coating is applied in the form of a paste to a substrate on each electrode between two adjacent ribs to form a phosphor layer including phosphor particles between the ribs on the substrate. The substrate is positioned with respect to another substrate having electrodes thereon to form discharge spaces between the substrates. The discharge spaces are filled with a discharge gas to produce a plasma display panel.
