Abstract
A quantum dot light-emitting device and a manufacturing method therefor, and a display panel. The quantum dot light-emitting device comprises: a quantum dot layer and an electron transport layer adjacent to the quantum dot layer; the electron transport layer comprises a first group, and the quantum dot layer comprises a second group; the first group and the second group each comprise a hydrophilic group. The first group and the second group are combined by means of a hydrogen bond on contact surfaces of the quantum dot layer and the electron transport layer, to enhance an interface interaction force between the quantum dot layer and the electron transport layer, thereby reducing interface defects of the quantum dot layer and the electron transport layer, and improving the electroluminescence performance and stability of the quantum dot device.
