Claim:
1. An organic light emitting diode comprising: a cathode; an anode; a light emitting layer provided between the cathode and the anode; an organic material layer comprising a heterocyclic compound represented by the following Formula 1 and provided between the cathode and the light emitting layer; and an organic material layer comprising a carbazole derivative represented by the following Formula 3 and provided between the anode and the light emitting layer: in Formula 1, Ar1 to Ar3 are different from each other, Ar1 and Ar2 are each independently a substituted or unsubstituted aryl group; or a substituted or unsubstituted heterocyclic group, Ar3 is represented by the following Formula 2, in Formula 2, R1 to R4 are the same as or different from each other, and each independently hydrogen; deuterium; a halogen group; a nitrile group; a nitro group; a hydroxy group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryloxy group; a substituted or unsubstituted alkylthioxy group; a substituted or unsubstituted arylthioxy group; a substituted or unsubstituted alkylsulfoxy group; a substituted or unsubstituted arylsulfoxy group; a substituted or unsubstituted alkenyl group; a substituted or unsubstituted silyl group; a substituted or unsubstituted boron group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heterocyclic group, or combine with an adjacent group to form a substituted or unsubstituted hydrocarbon ring or a substituted or unsubstituted hetero ring, or the substituents in the same carbon combine with each other to form a substituted or unsubstituted spiro bond, L1 is a direct bond; a substituted or unsubstituted arylene group; or a substituted or unsubstituted divalent heterocyclic group, l is an integer of 1 to 5, m is an integer of 1 to 3, n is an integer of 1 to 4, and when l, m, and n are each an integer of 2 or more, two or more structures in the parenthesis are the same as or different from each other, in Formula 3, Ar4 and Ar5 are the same as or different from each other, and hydrogen; deuterium; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heterocyclic group, L2 is a direct bond; or a substituted or unsubstituted arylene group, o is an integer of 0 to 5, and when o is an integer of 2 or more, two or more L2's are the same as or different from each other, R5 to R11 are the same as or different from each other, and each independently hydrogen; deuterium; a substituted or unsubstituted alkyl group; substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group, or combine with an adjacent group to form a substituted or unsubstituted hydrocarbon ring or a substituted or unsubstituted hetero ring, and Y1 and Y2 are the same as or different from each other, and each independently hydrogen; deuterium; a substituted or unsubstituted alkyl group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heterocyclic group, or Y1 and Y2 combine with each other to form a substituted or unsubstituted hydrocarbon ring or a substituted or unsubstituted hetero ring, wherein a HOMO energy level of the heterocyclic compound represented by Formula 1 is 6 eV or more.
