摘要
The present disclosure relates to a quantum dot light-emitting diode, comprising: a first electrode layer, a hole transport layer, a quantum dot light-emitting layer, an electron transport layer, and a second electrode layer, which are sequentially formed on a base substrate; and a buffer layer arranged between the quantum dot light-emitting layer and the electron transport layer, wherein the buffer layer is configured such that a difference between an electron injection rate and a hole transport rate of the quantum dot light-emitting layer is less than a preset threshold. The present disclosure further relates to a method for preparing a quantum dot light-emitting diode, and an array substrate and a display device including the quantum dot light-emitting diode.
