An electrode structure is disclosed. The electrode structure consists of a seed layer, an electrode layer formed on the seed layer and a cover layer formed on the electrode layer. This electrode structure is for application 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 particularly-designed electrode structure. Moreover, the QD electroluminescent device has enhanced in the brightness, total current efficiency and EQE thereof. |
