Claim 0:
1. An organic light emitting device comprising:
a first electrode;
a second electrode disposed to face the first electrode; and
a light emitting layer disposed between the first electrode and the second electrode,
wherein the organic light emitting device comprises a first organic material layer including a compound represented by the following Chemical Formula 1 between the first electrode and the light emitting layer, and
a second organic material layer including a compound represented by the following Chemical Formula 2 between the second electrode and the light emitting layer:, in Chemical Formulae 1 and 2,
Ar1 is a substituted or unsubstituted aryl group having 6 to 30 carbon atoms; or a substituted or unsubstituted heterocyclic group having 2 to 30 carbon atoms,
Ar2 is a substituted or unsubstituted carbazole group; a substituted or unsubstituted benzocarbazole group; a substituted or unsubstituted benzonaphthofuran group; a substituted or unsubstituted dibenzofuran group; a substituted or unsubstituted dibenzothiophene group; a substituted or unsubstituted pyridine group; or a substituted or unsubstituted quinoline group,
L1 to L4 are the same as or different from each other, and are each independently a direct bond; or a substituted or unsubstituted arylene group having 6 to 30 carbon atoms,
L5 is a direct bond; a substituted or unsubstituted phenylene group; a substituted or unsubstituted naphthylene group; a substituted or unsubstituted biphenylylene group; a substituted or unsubstituted terphenylylene group; or a substituted or unsubstituted divalent phenanthrene group,
R1 to R5 are the same as or different from each other, and are each independently hydrogen; deuterium; a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms; a substituted or unsubstituted cycloalkyl group having 3 to 30 carbon atoms; or a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, or R1 and R2 or R3 and R4 are optionally bonded to each other to form a ring,
R11 to R16 are the same as or different from each other, and are each independently hydrogen; deuterium; a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms; a substituted or unsubstituted cycloalkyl group having 3 to 30 carbon atoms; a substituted or unsubstituted aryl group having 6 to 30 carbon atoms; or a substituted or unsubstituted heterocyclic group having 2 to 30 carbon atoms, and
a, d, and e are each an integer from 0 to 4, b and c are each an integer from 0 to 3, f is an integer from 0 to 8, and when a to f are 2 or more, each of R11 to R16 is the same as or different from each other,
provided that when R5 is a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms or a substituted or unsubstituted cycloalkyl group having 3 to 30 carbon atoms, and L5 is a bond, then Ar2 is a substituted or unsubstituted benzonaphthofuran group,
provided that when Ar2 is a substituted or unsubstituted pyridine group, then L5 is a substituted or unsubstituted phenylene group; a substituted or unsubstituted naphthylene group; a substituted or unsubstituted biphenylylene group; a substituted or unsubstituted terphenylylene group; or a substituted or unsubstituted divalent phenanthrene group.
