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