Abstract:
An organic light-emitting device includes a first electrode; a second electrode facing the first electrode; and an organic emission layer between the first electrode and the second electrode. The organic emission layer may include a compound represented by Formula 1: wherein Formula 1 contains an indenoindenyl moiety. The compound may increase hole mobility in the device when used as a hole transport and/or hole injection material, thereby improving its lifetime, current, voltage, and luminescent characteristics.
