Curable composition, cured layer using the composition, color filter including the cured layer and display device including the color filter

A curable composition, comprising:

• a quantum dot surface-modified with a first ligand and a second ligand having a structure different than the first ligand;
• and
• a polymerizable compound,
• wherein the first ligand is a silsesquioxane-based thiol ligand and the second ligand is represented by Chemical Formula 2, and
• wherein the first ligand and the second ligand are each independently attached directly to a surface of the quantum dot;
• wherein, in Chemical Formula 2,
• R1 is a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C3 to C20 cycloalkyl group, a substituted or unsubstituted C6 to C20 aryl group, or a combination thereof,
• L2 and L3 are each independently a substituted or unsubstituted C1 to C20 alkylene group, a substituted or unsubstituted C3 to C20 cycloalkylene group, a substituted or unsubstituted C6 to C20 arylene group, or a combination thereof, and
• n and m are each independently an integer from 0 to 100, and n+m≠0.
