Abstract
A method for manufacturing a quantum dot layer includes: performing first application of applying, to a position overlapping with a substrate, a first solution including a plurality of particles including a core and a first ligand, a first inorganic precursor, and a first solvent; performing first heating of heating first solution to a first temperature or higher after the performing first application, the first temperature being a higher temperature of a melting point of the first ligand and a boiling point of the first solvent; and performing second heating of heating the first inorganic precursor to a second temperature after the performing first heating, the second temperature being higher than the first temperature and being a temperature, at which the first inorganic precursor epitaxially grows around the core and at which a first shell configured to coat the core is formed to form a plurality of first quantum dots.
