COLOR GAMUT-ENLARGED FILM

摘要

PROBLEM TO BE SOLVED: To provide a color gamut-enlarged film excellent in various characteristics such as emission efficiency, durability and emission wavelength peak stability.SOLUTION: A color gamut-enlarged film comprises: a semiconductor nanoparticle; a ligand having at least one adsorption group to adsorb on the semiconductor nanoparticle; and binder. The ligand is a nonionic organic compound or oxide compound, and the adsorption group is a residue of oxo acid whose center atom is a sulfur atom or phosphorus atom or an N-oxide group.SELECTED DRAWING: None
