An ink composition including a semiconductor nanoparticle, a first organic ligand, and a polymerizable monomer; and a semiconductor nanoparticle-polymer composite prepared therefrom. The semiconductor nanoparticle includes a Group 11-13-16 compound including silver, indium, gallium, and sulfur. The first organic ligand includes an aromatic group and fluorine, and in the ink composition, the amount of the semiconductor nanoparticles is about 2 weight percent to about 70 weight percent based on a total weight of the ink composition.
