Abstract
The present disclosure relates to the technical field of display, and discloses a quantum dot light-emitting device and a preparation method thereof. The quantum dot light-emitting device includes a first electrode layer, a quantum dot light-emitting layer, an electron transport layer, a second electrode layer and a third electrode layer which are sequentially arranged in a stacked manner, wherein the side, facing away from the first electrode layer, of the third electrode layer is configured as a light exiting side; the second electrode layer and the third electrode layer are transparent electrode layers; and the work function of the second electrode layer is greater than the LUMO energy level of the electron transport layer and smaller than the work function of the third electrode layer.
