Abstract

The invention relates to a quantum dot light emitting device. The device comprises an anode layer, a hole transport layer, a quantum dot light emitting layer, an electron transport layer and a cathodelayer which are stacked in sequence; the quantum dot light emitting layer comprises quantum dots of a core-shell structure and barrier material particles dispersed in a gap between every two adjacentquantum dots, and the materials of the barrier material particles are the same as the materials of shells of the quantum dots. By dispersing the barrier material particles in the gaps of adjacent quantum dots, the electro-optical efficiency of the quantum dot light emitting device is effectively improved.

[0002] This application claims the priority of Chinese patent application "201611240294.0" filed on December 29, 2016, entitled "Quantum Dot Light-Emitting Device and Display Device", the entire content of which is incorporated herein by reference. technical field

[0003] The invention belongs to the field of display technology, and in particular relates to a quantum dot light-emitting device and a display device. Background technique

[0004] Quantum dot light-emitting diode (QLED) is a device that directly excites quantum dots to emit light. The working principle of QLED is very close to that of organic light-emitting diodes, that is, the external circuit injects electrons and holes into the device through the positive and negative electrodes respectively, and the injected carriers generally pass through the carrier transport layer to the light-emitting layer to recombine and emit light. QLED has the advantages of high de...
