Organic light emitting diode device

An organic light emitting diode device comprising:

• a first light emitting part between an anode and a cathode, the first light emitting part including a first light emitting layer;
• a second light emitting part comprising a second light emitting layer on the first light emitting part;
• and
• a first charge generation layer between the first light emitting part and the second light emitting part,
• wherein the first charge generation layer comprises at least two hosts, and at least one of the at least two hosts includes a pyrene compound indicated by the following Chemical Formula 1:
• wherein each of p, q, r, and s is 0, 1 or an integer that satisfies 1≦p+q+r+s≦4, and Ar1, Ar2, Ar3, and Ar4 are independently at least one among the following structures:
• wherein at least one of X1 to X6, at least one of X7 to X14, at least one of X15 to X22, at least one of X23 to X32, and at least one of X33 to X42 comprise at least one among C, N, S, and O, and R1, R2, R3, R4, and R5 are independently at least one among substituted or unsubstituted alkyl, aryl, hetero aryl, aromatic, hetero aromatic, aryl amine, and hetero aryl amine compounds.
