Description

Organic light-emitting device

Embodiments of the present invention relate to an organic light emitting device.

An organic light-emitting device is a self-light-emitting device having a wide viewing angle, excellent contrast, fast response time, excellent luminance, driving voltage and response speed characteristics, and being able to have multiple colors .

A hole transport region, an emission layer, an electron transport region, and a second electrode are sequentially formed on the first electrode in the organic light emitting device. Lt; / RTI > structure. The holes injected from the first electrode migrate to the light emitting layer via the hole transporting region and electrons injected from the second electrode migrate to the light emitting layer via the electron transporting region. The carriers such as holes and electrons recombine in the light emitting layer region to generate an exiton. This exciton changes from the excited state to the ground state and light is generated.
