Abstract:
An organic electroluminescence device is provided, which may include a first electrode, a hole transport region disposed on the first electrode, an emission layer disposed on the hole transport region, an electron transport region disposed on the emission layer, and a second electrode disposed on the electron transport region. The hole transport region may include a diamine compound represented by Formula 1, thereby exhibiting high light emission efficiency.
