Abstract:
An organic electroluminescence device (OLED) of an embodiment includes a first electrode, a hole transport region on the first electrode, an emission layer on the hole transport region, and an electron transport region on the emission layer. The hole transport region may include an amine compound represented by Formula 1, and the OLED may thereby exhibit high luminous efficiency:
