ABSTRACT:
Provided are a phosphor paste composition, a flat display device including the same, and a method of manufacturing the flat display device. The phosphor paste composition contains a phosphor with at least a heat-resistant material selected from a Group II atom-containing material, a Group III atom-containing material, and a Group IV atom-containing material, a binder, and an organic solvent. By using the phosphor paste composition, the deterioration of the phosphor can be prevented during a heat treating process. The flat display device includes a phosphor layer containing the phosphor coated with the heat-resistant material such that lifetime of the flat display device is increased and a permanent residual image phenomenon, the adsorption of water by the phosphor, and the like can be prevented.
