Solventless quantum dot composition, preparation method therefor, and cured film, color filter and display device which comprise same

A method for preparing a solventless quantum dot composition, the method comprising:

• (a) surface modifying quantum dots with a first ligand represented by Chemical Formula 1 and a second ligand of 3 to 40 carbon atoms containing a carboxyl group, wherein:
• Chemical Formula 1 is as follows:
• M is a divalent to tetravalent metal,
• X is an organic group of 3 to 20 carbon atoms, and
• n is an integer of 2 to 4;
• (b) centrifuging a reaction mixture of step (a) to obtain surface-modified quantum dots;
• and
• (c) dispersing the surface-modified quantum dots in a photopolymerizable monomer.
