Disclosed are a solvent-free type curable composition including (A) quantum dots; (B) a polymerizable monomer; and (C) a light diffusing agent having a primary particle diameter of 50 nm to 200 nm and a secondary particle diameter of 120 nm to 250 nm, a cured film produced using the same, a color filter including the cured film, and a display device including the color filter. The quantum dot-containing solvent-free type curable composition is possible to be re-dispersed within a short time with a reduced density while maximizing scattering effects for the quantum dots. Therefore, high luminance and high color of the color filter including the cured film produced using the composition may be realized.
