Abstract

The invention discloses a light-emitting panel, a display device and a manufacturing method of the light-emitting panel, and aims to solve the problem of unbalanced carrier injection of a light-emitting device in the prior art. The light-emitting panel comprises an underlayer substrate, at least two electrode layers located on one side of the underlayer substrate and a light-emitting layer locatedbetween the two electrode layers, wherein at least one electrode layer is provided with an interface modification layer on the side facing the light-emitting layer, and the interface modification layer comprises a condensed ring structure, a first charged group connected to the side, which deviates from the light-emitting layer, of the condensed ring structure, and a second charged group connected to the side, which faces the light-emitting layer, of the condensed ring structure, the first charged group and the second charged group have different charges, so that the interface modification layer has a dipole moment to adjust the work function of the electrode layer in contact with the interface modification layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light emitting panel, a display device and a method for manufacturing the light emitting panel. Background technique [0002] Organic Light Emitting Diode (OLED) displays have the advantages of low energy consumption, self-illumination, wide viewing angle and fast response, and are one of the hotspots in the field of display research today. [0003] Quantum Dots Light Emitting Doide Display (QLED) is a new type of display technology developed on the basis of organic light emitting displays. The difference between the two is that the light-emitting layer in QLED is a quantum dot layer. Its principle is that electrons / holes are injected into the quantum dot layer through the electron / hole transport layer, and electrons and holes recombine in the quantum dot layer to emit light. Compared with organic light-emitting diode display devices (OLED), QLED has the advantages of narrow ...
