Abstract:
A display device including a first light emitting element including a first emission layer and a first charge transport layer adjacent to the first emission layer, the first emission layer including a first quantum dot to emit first light, and a second light emitting element including a second emission layer and a second charge transport layer adjacent to the second emission layer, the second emission layer including a second quantum dot to emit second light that is longer in wavelength than the first light. The first charge transport layer includes a first metal oxide. The second charge transport layer includes a second metal oxide different from the first metal oxide.
