A quantum dot composition, a preparation method therefor, and a cured film, a color filter and a display device that comprise the same are described. Specifically, a solventless quantum dot composition comprises quantum dots, which are surface-treated with two types of ligands. As a result, the quantum dot composition exhibits low viscosity, excellent optical properties, and high storage stability.
