Abstract:
An organic light emitting element includes a first electrode a second electrode that faces the first electrode, an emission layer between the first electrode and the second electrode, the emission layer including quantum dots, and a hole transport layer between the first electrode and the emission layer. The quantum dots include at least one of a Group I-VI compound, a Group II-VI compound, and a Group III-VI compound. The hole transport layer includes at least one of a p-doped Group I-VI compound, a p-doped Group II-VI compound, and a p-doped Group III-VI compound.
