An ink composition comprising:

a plurality of quantum dots,
a reactive organic compound, and
a solvent,
wherein the plurality of quantum dots do not include cadmium or lead, and
the reactive organic compound is represented by Chemical Formula 1:
in Chemical Formula 1,
Ar1 is a substituted or unsubstituted aromatic hydrocarbon group having 6 to 60 carbon atoms,
L1 is a single bond, or an oxygen atom,
L2 is a single bond, a substituted or unsubstituted saturated hydrocarbon group having 1 to 60 carbon atoms, or a substituted or unsubstituted aromatic hydrocarbon group having 6 to 60 carbon atoms, and
X is a group selected from the groups represented by the following formulae (1-1) to (1-37):
in the formulae (1-1) to (1-37), * represents a binding site,
in the formulae (1-1) to (1-5), (1-7), (1-12), (1-19), (1-22), (1-23), (1-27), and (1-28), a1 independently represents an integer of greater than or equal to 2 and less than or equal to 4,
in the formulae (1-6), (1-8), (1-9), (1-13) to (1-15), (1-20), (1-25), and (1-30), a2 independently represents an integer of greater than or equal to 1 and less than or equal to 3, a3 independently represents 1 or 2, and the sum of a2 and a3 is independently 2, 3, or 4,
in the formulae (1-10), (1-16), (1-17), (1-21), (1-26), and (1-31), a4 independently represents 1 or 2, a5 independently represents 1, a6 independently represents 1 or 2, and the sum of a4, a5, and a6 independently represents 3 or 4,
in the formulae (1-24) and (1-29), a7 independently represents an integer of greater than or equal to 1 and less than or equal to 3, a8 independently represents an integer of greater than or equal to 1 and less than or equal to 3, and the sum of a7 and a8 independently represents 2, 3, or 4,
in the formula (1-32), a9 is an integer of greater than or equal to 2 and less than or equal to 18,
in the formula (1-37), a10 represents 1 or 2, and a11 represents 1 or 2,
in the formulae (1-5) and (1-6), Ar2 is each independently a substituted or unsubstituted aromatic hydrocarbon group having 6 to 60 carbon atoms, and
in the formulae (1-27) to (1-31), Y is each independently —O—, —S—, —C(CH3)2—, or a diphenylmethylene group.
