An amine-based compound represented by Formula 1, in which one of R
1
to R
10
is a group represented by Formula 2, and an organic light-emitting device including the same are provided:
When the amine-based compound is included in an organic light-emitting device as a hole transport material, the device may exhibit excellent I-V-L characteristics, including a low driving voltage, improved efficiency, and improved lifespan.

The present disclosure provides a condensed-cyclic compound represented by Formula 1, in which one selected from R
1
to R
8
is a monoamine represented by Formula 2:
The condensed-cyclic compound represented by Formula 1 may act as a hole transport material having a suitable energy level and band-gap. Further, the condensed-cyclic compound represented by Formula 1 has a fused core, and accordingly may have a high glass transition temperature (Tg), high melting point, and improved resistance to high temperatures. Therefore an organic light-emitting device including the condensed-cyclic compound represented by Formula 1 may retain high durability during storing and/or driving.
