Abstract:
Disclosed herein is a carboxylic ester dispersant shown in the following Formula 1 and a sulfide phosphor paste composition containing the dispersant. The dispersant improves the dispersibility of the sulfide phosphor paste composition and prevents oxidation by a solvent, thus improving processability and the luminescent properties of a phosphor film made from the paste and of a display produced using the film. In Formula 1, n is 1-20.
