Classification: CPC H  C | IPC C  H

Claim 13:
14. A manufacturing method of a light emitting diode device, comprising:
forming a quantum dot film layer comprising a first reactant on a carrier substrate,
wherein the first reactant comprises a quantum dot body, a ligand molecule A connected to the quantum dot body, and a ligand molecule B connected to the quantum dot body;

contacting a transfer substrate with the quantum dot film layer to form a hydrogen bond between the ligand molecule B in the first reactant and the transfer substrate, and to adhere up the quantum dot film layer;
bonding the transfer substrate with the quantum dot film layer to a base substrate formed with a modified molecule to undergo atom transfer radical polymerization between the ligand molecule A in the first reactant on a surface of the quantum dot film layer and the modified molecule, and to undergo continuous atom transfer radical polymerization inside the quantum dot film layer to form a quantum dot light emitting layer,
wherein the base substrate is formed with a first electrode and a carrier functional layer on one side, facing away from the base substrate, of the first electrode, and
the modified molecule is connected to one surface, facing away from the first electrode, of the carrier functional layer;

removing the transfer substrate; and
forming a second electrode on a side, facing away the carrier functional layer, of the quantum dot light emitting layer.
