Abstract: An electroluminescent device and a manufacturing method therefor are provided. The electroluminescent device includes an anode, a hole function layer, a quantum dot emission layer, an electron function layer, and a cathode that are sequentially stacked. The quantum dot emission layer is doped with a carrier transport material. The carrier transport material doped in the quantum dot emission layer not only can improve the conductivity of the quantum dot light emitting material and facilitate the injection and the transport of carriers, but also can increase the recombination probability of the carriers.

Abstract: The present application provides a display panel, a manufacturing method thereof, and a display device. By defining a first height difference between a first terminal part and a second terminal part of a first bonding terminal, so that after attaching a protective layer, a suspended area is defined between the protective layer and the first terminal part, so that when preparing a surrounding wire, a metal conductive thin film is disconnected in the suspended area, thus the surrounding wire will not be lifted when the protective layer is removed, so as to alleviate a problem of peeling of a surrounding wire of existing display panels when removing a protective layer.
