Provided is an organic light-emitting diode comprising: a positive electrode; a negative electrode provided to face the positive electrode; a light-emitting layer provided between the positive electrode and the negative electrode; a hole adjusting layer having one or more layers provided between the positive electrode and the light-emitting layer, in which one or more layers of the hole adjusting layers includes at least one compound of Formulae 1 or Formula 2, and the light-emitting layer includes a compound of Formula 3:
wherein:
G1 to G4 are each independently a substituted or unsubstituted alkyl or aryl group;
L1 to L7 are each independently a direct bond, or a substituted or unsubstituted arylene or heteroarylene group;
at least one of X1 to X3 is N, and any remaining is each CR8; and
Ar1 to Ar6 are each independently a substituted or unsubstituted aryl or heteroaryl group, or Ar2 and Ar3 together form a substituted or unsubstituted hetero ring.
The present invention relates to a novel compound and an organic light emitting device using the compound, and the compound according to the present invention may largely improve a life span, efficiency, electrochemical stability and thermal stability of the organic light emitting device.
