PURPOSE: To obtain a photosensitive phosphor paste for plasma display panel which comprises a phosphor powder, a photosensitive resin composition and an ultraviolet absorber, enables prolonged life, high minuteness, high-density display with high display quality and improved brightness efficiency. CONSTITUTION: This phosphor paste comprises (A) a phosphor powder 7 such as Y2 O3 of which 50wt.% has particle sizes of 1-15μm and a specific surface area of 0.1-2.0m<2> /g, (B) a photosensitive resin composition containing an acrylic copolymer bearing carboxyl groups and ethylenically unsaturated groups on the side chain or molecular chain ends, and (C) an ultraviolet absorber such as an organic dye having an integral value of absorbance of 30-100 at wavelength from 350 to 450nm. The amount of the component C is preferably 0.05-2wt.% based on the component A. |
