An organic electroluminescent device comprising:
- a first electrode;
- a hole transport region disposed on the first electrode, and the hole transport region comprises at least one of a hole injection layer or a hole transport layer
- an emission layer disposed on the hole transport region;
- an electron transport region disposed on the emission layer, and the electron transport region comprises at least one of an electron injection layer of an electron transport layer;
- and
- a second electrode disposed on the emission layer;
- and
- wherein at least one of the hole transport region or the emission layer comprises an monoamine derivative represented by the following Formula 1:
- wherein, in Formula 1,
- Ar1, Ar2 and Ar3 are independently a substituted with at least one of an alkyl group or an aryl group or unsubstituted aryl group, a substituted or unsubstituted heteroaryl group including at least one of O, P or S as a hetero atom, or a substituted or unsubstituted benzocarbazole group, at least one of Ar1, Ar2 or Ar3 being substituted with one substituted or unsubstituted silyl group,
- L is a single bond, a substituted or unsubstituted arylene group or a substituted or unsubstituted heteroarylene group, and
- at least one of Ar1, Ar2 or Ar3 is represented by the following Formula 8:
