Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a cadmium sulfide nano-crystal emitting light with multiwavelengths, the cadmium sulfide nano-crystal produced by the same, and a white light emitting diode element using the same. SOLUTION: The method for producing the semiconductor cadmium sulfide nano-crystal comprises of a step obtaining a cadmium precursor solution by mixing a cadmium precursor and a dispersing agent with a solvent having a weak coordination power and heating the resulting mixture, a step of obtaining a sulfur precursor solution by dissolving a sulfur precursor in a solvent having a weak coordination power, and a step of growing the cadmium sulfide crystal by injecting the sulfur precursor solution into the heated cadmium precursor solution.
