Abstract
A quantum dot-polymer composite film includes: a plurality of quantum dots, wherein a quantum dot of the plurality of quantum dots includes an organic ligand on a surface of a the quantum dot; a cured product of a photopolymerizable monomer including a carbon-carbon unsaturated bond; and a residue including a residue of a high-boiling point solvent, a residue of a polyvalent metal compound, or a combination thereof.
Claims39
A quantum dot-polymer composite film, comprising:
- a plurality of quantum dots, wherein a quantum dot of the plurality of quantum dots comprises an organic ligand on a surface of the quantum dot;
- a cured product of a photopolymerizable monomer comprising a carbon-carbon unsaturated bond;
- and
- a residue comprising a residue of a high-boiling point solvent, a residue of a polyvalent metal compound, or a combination thereof.
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 film;
- disposing a material comprising a high-boiling point solvent, a polyvalent metal compound solution, or a combination thereof on the patterned film to form a liquid barrier layer;
- and
- heat-treating the patterned film on which the liquid barrier layer is formed to manufacture the quantum dot-polymer composite film.
