Abstract: Disclosed herein is an organic light emitting diode device. The organic light emitting diode device includes an anode, a cathode and a light emitting layer. The light emitting layer has a structure where a blue light emitter and a red/green simultaneous light emitter are stacked. The red/green simultaneous light emitter has a structure where a red light emitter and a green light emitter are stacked. The red light emitter includes a red host compound, and in some embodiments, the red host compound includes a spirobisfluorene-based compound where an aryl amino group is substituted. The green light emitter includes a green host compound, and the green host compound includes a mixture of a first green host compound and a second green host compound. In some embodiments, the first green host compound includes a biscarbazole-based compound and the second green host compound includes an indolocarbazole-based compound.
