ABSTRACT:
An organic light emitting device includes first, second, and third pixels each displaying a different color. Each pixel includes a first electrode, a second electrode facing the first electrode, and an emission layer between the first and second electrodes. The first electrodes of the first and second pixels respectively include a first transparent conductive layer and a translucent conductive layer disposed on at least one of lower and upper portions of the first transparent conductive layer and forming microcavities together with the second electrodes, and the first electrode of the third pixel includes a second transparent conductive layer that is different from the first transparent conductive layer and a translucent conductive layer disposed on at least one of upper and lower portions of the second transparent conductive layer and forming a microcavity together with the second electrode.
