A light-emitting element may include a first electrode, a second electrode facing the first electrode, a first hole transport layer disposed above the first electrode, a first electron transport layer disposed between the first hole transport layer and the second electrode. A first light-emitting part and a second light-emitting part that emit different light may be disposed between the first hole transport layer and the first electron transport layer. The first light-emitting part may include a first blue emission layer, a second electron transport layer, a charge generation layer, and a second blue emission layer, and the first blue emission layer may be disposed above the first hole transport layer. At least one of the first electron transport layer and the second electron transport layer may be directly disposed above at least one of the first blue emission layer and the second blue emission layer.
