Abstract: A light emitting device includes a first electrode and a second electrode facing each other on a substrate, and an intermediate layer including a first blue stack, a first charge generation layer, and a phosphorescent stack between the first electrode and the second electrode. The first blue stack includes a hole transport layer, a first blue light-emitting layer, a second blue light-emitting layer, and an electron transport layer in this order. Further, the first blue light-emitting layer includes a first host and a blue dopant, and the second blue light-emitting layer includes a second host and the blue dopant. Also, a triplet energy level of the first host is greater than a triplet energy level of the second host and is smaller than a triplet energy level of the dopant.

Abstract: Discussed is a light-emitting device including a first light-emitting layer so that a dopant having a hole trapping property is adjacent to a hole transport layer, and a second light-emitting layer that comes into contact with the first light-emitting layer to induce main light emission, thereby widening an emission zone and improving the efficiency and lifespan of the light-emitting layer. Also discussed is a light-emitting display including the light-emitting device. The first and second blue light-emitting layers can include a same host BH and different first and second blue dopants, respectively, and the first blue dopant can have a higher highest occupied molecular orbital (HOMO) energy level than a HOMO energy level of the hole transport layer.
