Summary:PURPOSE: Provided is a phosphor paste composition for plasma display panels(PDP), which is very stable and has desirable screen-printing properties. CONSTITUTION: The phosphor paste for plasma display panels comprises a phosphor dispersed in an organic paste comprising a solvent, a binder, at least one dispersant containing stearic acid, and a plasticizer. In the paste, the weight ratio of stearic acid to the binder is 1:1 - 1:2.5. Particularly, the binder is polyvinyl butyral or ethylcellulose, the solvent is an alcohol solvent, and the plasticizer is a phthalate. Further, the phosphor is selected from BaMgAl14O23:Eu2+, (Y,Gd)BO3:Eu, or Zn2SiO4:Mn. 용매, 결합제, 스테아린산을 포함하는 적어도 하나의 분산제, 및 가소제를 포함하는 유기 페이스트내에 분산된 형광체를 포함하는, 플라즈마 디스플레이 패널(PDP)용 형광체 페이스트 조성물이 제공된다. 이 페이스트 조성물은 매우 안정하고, 바람직한 스크린-인쇄 성질을 가진다. 뿐만 아니라, 페이스트에 함유된 형광체는 결합제가 모두 연소된 후에도 이의 초기 명도의 높은 %를 보유한다.
