1. A quantum dot light-emitting device, comprising:
a substrate and a cathode arranged on the substrate;
an electron transport layer arranged on one side of the cathode, away from the substrate, wherein the electron transport layer comprises a plurality of pixel regions;
an adhesive layer arranged on one side of the electron transport layer, away from the cathode; and
a quantum dot film layer arranged on one side of the adhesive layer, away from the electron transport layer, wherein both the quantum dot film layer and the adhesive layer are located in the pixel regions; wherein
the adhesive layer is respectively connected to the electron transport layer and the quantum dot film layer through at least one of chemical bonding and physical entanglement.
