Technical Field

One or more embodiments of the present disclosure relate to an organometallic compound, an organic light-emitting device including the organometallic compound, and an apparatus including the organic light-emitting device.

Background

Organic light emitting devices are self-light emitting devices that produce full color images and also have wide viewing angles, high contrast, short response times, and excellent luminance, driving voltage, and response speed characteristics, compared to other devices in the art.

One example of such an organic light emitting device may include a first electrode disposed on a substrate, and a hole transport region, a light emitting layer, an electron transport region, and a second electrode sequentially disposed on the first electrode. The holes provided from the first electrode may move toward the light emitting layer through the hole transport region, and the electrons provided from the second electrode may move toward the light emitting layer through the electron transport region. Carriers (such as holes and electrons) recombine in the light emitting layer to generate excitons. These excitons transition (e.g., transition or relax) from an excited state to a ground state, thereby generating light.

Disclosure of Invention

One or more embodiments of the present disclosure provide a novel organometallic compound, an organic light-emitting device including the organometallic compound, and an apparatus including the organic light-emitting device.
