Abstract
A semiconductor device includes an anode, a cathode, a first functional layer between the anode and cathode, and a second functional layer between the first functional layer and the cathode. The first functional layer contains a first quantum dot having a first ligand, and the second functional layer contains a second quantum dot having a second ligand different from the first ligand. The second ligand is an aromatic compound having a sulfide bond and an ester bond.
