A method of manufacturing a quantum dot-polymer composite film, the method comprising:
- disposing a photosensitive composition comprising
- a plurality of quantum dots on a surface, wherein a quantum dot of the plurality of quantum dots comprises an organic ligand on a surface of the quantum dot,
- a photopolymerizable monomer comprising a carbon-carbon unsaturated bond,
- a photoinitiator, and
- a solvent, on a substrate followed by drying to obtain a film;
- exposing the film under a mask to form a patterned film;
- developing the patterned film;
- disposing a solvent with a high-boiling point of about 200°C. to about 350°C., and optionally, including a polyvalent metal compound on the patterned film;
- and
- heat-treating the patterned film to manufacture the quantum dot-polymer composite film.
