PURPOSE: A phosphor paste is provided to increase the life of a panel and stability, and to decrease a badness rate by increasing an adhesive strength on the interface of a phosphor film printed on the rear plate of a plasma display panel. CONSTITUTION: A phosphor paste comprises a glass frit for increasing adhesive strength on the interface of a phosphor paste. The phosphor paste is two type of paste, a printing phosphor paste and a photosensitive phosphor paste. The printing phosphor paste is composed of the glass frit, a surface active agent and an acid-fast agent in addition to a phosphor power, a binder, a filler, a plasticizer, and a solvent. The photosensitive phosphor paste is composed of a composition comprising a phosphor powder, a photosensitive binder, a filler, a plasticizer, a solvent, a surface active agent, an acid fast agent, a glass frit, and a photoinitiator. An amount of the glass frit is used between approximately 3% and 15% as compared with that of the phosphor power.
