US 2017/0287985 A1 · ORGANIC LIGHT EMITTING DISPLAY DEVICE

Abstract

An organic light emitting display device includes a first emission part between an anode and a cathode and a second emission part on the first emission part. At least one of the first emission part and the second emission part includes at least three emission layers emitting lights of different colors, and one of the at least three emission layers include a green emission layer including a phosphorescent material. Accordingly, a lifetime and color reproduction rate of the organic light emitting display device having green lifetime is enhanced.
