Abstract: Disclosed belongs to the technical field of displaying, and relates to a quantum dot light emitting diode and a method. for manufacturing the same, and a display panel. The method for manufacturing the quantum dot light emitting diode comprises steps of forming a cathode, an electron transport layer doping a substance capable of trapping current carriers comprising a N-type metal oxide and a quantum dot material with a surface ligand comprising a hydroxyl group, a light emitting layer, a hole transport layer and an anode. The quantum dot light emitting diode can effectively reduce the electron transport or injection by incorporating a substance capable of trapping current carriers, and therefore significantly improve the luminous efficiency. Meanwhile, the PEDOT:PSS with high conductivity is used as the transparent anode, and thus the whole structure may be manufactured totally by using solution processes at low cost and without high vacuum coating machines.
