Abstract
A quantum dot light emitting structure and a method for manufacturing the quantum dot light emitting structure, and an array substrate are disclosed. The quantum dot light emitting structure includes: a quantum dot light emitting layer; an electrode; and an electron transport layer located between the quantum dot light emitting layer and the electrode, the quantum dot light emitting structure further comprises an electron blocking layer located in the electron transport layer, a root-mean-square (RMS) roughness of a surface, close to the quantum dot light emitting layer, of the electron transport layer is different from a root-mean-square (RMS) roughness of a surface, away from the quantum dot light emitting layer, of the electron transport layer.
