Claim:
1. A manufacturing method of a quantum dot light emitting diode, comprising: forming a first electrode and a second electrode on a substrate, forming a quantum dot light emitting layer that includes at least a red quantum dot, a green quantum dot and a blue quantum dot between the first electrode and the second electrode, and forming a black matrix at least among the red quantum dot, the green quantum dot and the blue quantum dot, wherein forming of the red quantum dot includes; dissolving a zinc sulfide nano semiconductor compound with a particle diameter of 10 to 12 nm into a first organic solvent to form a first mixture; and coating the first mixture on the substrate and conducting a first patterning process treatment so as to form the red quantum dot after the organic solvent has volatized; wherein forming of the green quantum dot includes: dissolving a zinc sulfide nano semiconductor compound with a particle diameter of 7 to 8 nm into a second organic solvent to form a second mixture; and coating the second mixture on the substrate and conducting a second patterning process treatment so as to form the green quantum dot after the organic solvent has volatized; and wherein forming of the blue quantum dot includes: dissolving a zinc sulfide nano semiconductor compound with a particle diameter of 4 to 5 nm into a third organic solvent to form a third mixture; and coating the third mixture on the substrate and conducting a third patterning process treatment so as to form the blue quantum dot after the organic solvent has volatilized.
