Abstract
Provided is an organic electroluminescence device including 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 emission layer includes a polycyclic compound represented by Formula 1, and thus the organic electroluminescence device exhibits high luminous efficiency.
