Abstract: The present disclosure relates to a crosslinking ligand, a method for patterning a nanoparticle layer, a quantum dot light-emitting device, and a display device. The crosslinking ligand includes: at least two coordinating groups, at least one photosensitive degradation group and at least one thermosensitive crosslinking group, both of which are connected between the coordinating groups. The method for patterning the nanoparticle layer includes: forming a nanoparticle layer on a substrate; attaching a solution containing the crosslinking ligand to the substrate, to allow the crosslinking ligand to form a crosslinking between nanoparticles; performing a light irradiation treatment on a preset region of the substrate; removing the nanoparticles in the preset region; and performing a heat treatment on the substrate. The present disclosure does not need to design the structure of the ligand of the nanoparticles, and can form a nanoparticle layer with high resolution, simple process and high realizability.
