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 common blue emission material layer which is included in common in a plurality of pixels emitting lights having different wavelength ranges, a second emission unit configured to include a red emission material layer, a green emission material layer, and a blue emission material layer which respectively emit lights having different wavelength ranges, 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 formed as a semi-transmissive electrode, and configured to supply an electric charge having a second polarity to the first emission unit and the second emission unit.
