Abstract
The disclosure provides a quantum dot mixture, a quantum dot light emitting layer and a preparation method thereof, relates to the field of display technology. The preparation method of quantum dot light emitting layer includes: providing a substrate; forming a quantum dot film layer on one side of the substrate, which comprises a first quantum dot body-first ligand and a second quantum dot body-second ligand; exposing a predetermined region of the substrate to form a cross-linkage or a salt insoluble in the developer via a reaction between the first ligand and the second ligand in the predetermined region of the quantum dot film layer; and developing to remove the quantum dot film layer in the non-predetermined region of the substrate, and obtain the quantum dot light emitting layer. The disclosure provides a basis for the formation of the quantum dot light emitting layer using photolithography technology.
