1. A method for manufacturing a resin molded product, for a backlight of a display, the resin molded product obtained by molding a resin composition in which quantum dots are dispersed, the method comprising:
stirring resin and metal soap to form a resin mixture, wherein the metal soap is contained in the resin in a range of 1 ppm to 40,000 ppm with respect to the resin;
obtaining a quantum dot liquid by dispersing the quantum dots in a solvent;
obtaining a resin composition in a solid state by kneading the quantum dot liquid in the resin mixture, wherein a weight ratio of the metal soap to the quantum dots is within a range from 1/10:1 to 10:1; and
forming a sheet-like shaped resin molded product by extrusion molding the resin composition in the solid state.
