1. A method for manufacturing a light-emitting device provided with, on a substrate, a light-emitting element including a first electrode, a second electrode, and a quantum dot layer interposed between the first electrode and the second electrode, the method comprising:
forming the quantum dot layer,
the forming the quantum dot layer including
performing first application that involves applying a first solution containing a plurality of first quantum dots each including a first core and a first shell with which the first core is coated, a first ligand to coordinate with each of the plurality of first quantum dots, and a first solvent on a position overlapping with the substrate,
performing first light irradiation, subsequent to the performing first application, that involves irradiating with light using a first photomask, from above the substrate, the position where the first solution is applied, and forming a first exposure region exposed by the first light irradiation in which the first ligand melts and the first solvent vaporizes, and a first non-exposure region at a position different from a position exposed by the first light irradiation,
performing first cooling, subsequent to the performing first light irradiation, that involves lowering a temperature of the first quantum dot to a temperature equal to or lower than a melting point of the first ligand and solidifying the first ligand, and
performing first removal, subsequent to the performing first cooling, that involves washing an upper layer relative to the substrate with the first solvent to remove the first solution in the first non-exposure region.
