MANUFACTURE OF PHOSPHOR PATTERN, THE PHOSPHOR PATTERN, PHOSPHOR PATTERN FORMING ORGANIC ALKALI DEVELOPER, PHOSPHOR PATTERN FORMING EMULSION DEVELOPER, AND BACK SURFACE PLATE FOR PLASMA DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a phosphor pattern, a phosphor pattern forming a organic alkali developer, a phosphor pattern forming emulsion developer for manufacturing the phosphor pattern with good yield, without generating change in a light-emitting characteristic, the phosphor pattern without generating change in the light-emitting characteristic and a back surface plate for plasma display panel provided with the phosphor pattern. SOLUTION: A phosphor pattern forming emulsion developer containing alkali metal or alkali earth metal at 2 wt.% or lower with respect to a phosphor and obtained by burning a phosphor pattern precursor containing organic material and the phosphor and composed of aromatic amine, a phosphor pattern forming organic alkali developer containing aromatic amine or tetraalkylammonium hydroxide and emulsion containing water and solvent is used.
