The present invention discloses an electrode structure, comprising: a seed layer, an electrode layer formed on the seed layer and a cover layer formed on the electrode layer. This electrode structure can be applied in the manufacture of a quantum dots electroluminescent device, so as to act as an anode electrode or a cathode electrode of the QD electroluminescent device. Experimental data have revealed that, there is no transmittance imbalance occurring in the QD electroluminescent device using the electrode structure of the present invention. Moreover, the QD electroluminescent device has enhanced in the brightness, total current efficiency and EQE thereof. |
