Abstract
An organic light emitting device includes a first electrode formed over a substrate, an intermediate layer that is formed over the first electrode and includes an organic light emitting layer, and a second electrode that includes a central electrode unit disposed in a central region and a peripheral electrode unit separated from the central electrode unit and disposed in a peripheral region. The intermediate layer is disposed between the first and second electrodes. The organic light emitting device can readily secure a uniform brightness characteristic.
