    Abstract: An electronic device includes a base layer and a display element layer including a pixel definition layer having an opening defined therethrough, a light emitting element, and a light receiving element. Each of the light emitting element and the light receiving element includes a first electrode, a hole transport region disposed on the first electrode, an electron transport region disposed on the hole transport region, and a second electrode disposed on the electron transport region. The light emitting element includes a light emitting layer disposed between the hole transport region and the electron transport region. The light receiving element includes a light receiving layer disposed between the hole transport region and the electron transport region and an electron extraction layer, including an n-dopant material, disposed between the light receiving layer and the electron transport region. The light receiving element converts a light incident thereto into an electrical signal.

    Abstract: Embodiments provide a light-emitting device that include a first electrode, a second electrode facing the first electrode, and an interlayer between the first electrode and the second electrode. The interlayer includes an emission layer, and the emission layer includes a first emission layer and a second emission layer. The first emission layer includes a first host and a first-first dopant, or a first host, a first-first dopant, and a first-second dopant. The second emission layer includes a second host and a second-first dopant, or a second host, a second-first dopant, and a second-second dopant. The emission layer includes the first-second dopant and/or the second-second dopant, the first emission layer and the second emission layer directly contact each other, and a thickness of the second emission layer is greater than a thickness of the first emission layer.
