Claims15
An organic light emitting device, comprising:
- an anode;
- a cathode;
- and
- a first organic material layer and a second organic material layer provided between the anode and the cathode,
- wherein the first organic material layer includes a compound of the following Chemical Formula 1;
- and
- the second organic material layer includes a compound of the following Chemical Formula 2:
- wherein in Chemical Formula 1:
- L11 to L14 are the same as or different from each other, and each independently is a direct bond or a substituted or unsubstituted arylene group;
- Ar1 and Ar2 are the same as or different from each other, and each independently is a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group;
- R1 is hydrogen, deuterium, a halogen group, a cyano group, a substituted or unsubstituted silyl 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 aryl group, or a substituted or unsubstituted heterocyclic group;
- and
- a is an integer of 0 to 8, and when a is 2 or greater, the two or more R1s are the same as or different from each other;
- wherein in Chemical Formula 2:
- L3 and L4 are the same as or different from each other, and each independently is a direct bond or a substituted or unsubstituted arylene group;
- Ar3 is a substituted or unsubstituted heterocyclic group;
- Ar4 is a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group;
