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

A curable composition, comprising:

• (A) a quantum dot surface-modified with at least two quantum dot surface-modifying materials;
• and
• (B) a polymerizable compound,
• wherein the quantum dot surface-modifying materials include a first surface-modifying material represented by Chemical Formula 1 and a second surface-modifying material represented by Chemical Formula 2:
• wherein, in Chemical Formula 1 and Chemical Formula 2,
• R1 is a substituted or unsubstituted C6 to C20 aryl group,
• R2 is a C1 to C20 alkyl group unsubstituted or substituted with a C1 to C10 alkyl group,
• L1 and L2 are each independently a substituted or unsubstituted C1 to C20 alkylene group, and
• n1 and n2 are each independently an integer from 2 to 20.
