Organic light emitting device

摘要

Disclosed is an organic light emitting device. The organic light emitting device includes a first emission unit configured to include a first red emission layer which emits red light, a first green emission layer which emits green light, and a first blue emission layer which emits blue light, a second emission unit configured to include a second red emission layer which emits red light, a second green emission layer which emits green light, and a second blue emission layer which emits blue light, a charge generation layer disposed between the first emission unit and the second emission unit, a first electrode formed as a reflective electrode, and configured to supply an electric charge having a first polarity to the first emission unit and the second emission unit, and a second electrode configured to supply an electric charge having a second polarity to the first and second emission units.
