1. A semiconductor device comprising:
an anode;
a cathode;
a first functional layer between the anode and the cathode, the first functional layer containing a first quantum dot having a first ligand; and
a second functional layer between the first functional layer and the cathode, the second functional layer containing a second quantum dot having a second ligand different from the first ligand, the second ligand being an aromatic compound having a sulfide bond and an ester bond.
