    Abstract: The present disclosure provides a light-emitting device and manufacturing method thereof, and a display apparatus containing the light-emitting device. The light-emitting device comprises a quantum dot light-emitting layer, an electron transport layer, and an energy transfer layer. The quantum dot light-emitting layer comprises a quantum dot material. The energy transfer layer is between the quantum dot light-emitting layer and the electron transport layer. The energy transfer layer is configured to facilitate a transfer of energy from the electron transport layer to the quantum dot light-emitting layer such that the quantum dot light-emitting layer has an improved electroluminescence efficiency compared with the quantum dot light-emitting layer having an energy transferred directly from the electron transport layer without the energy transfer layer.
