Abstract:
A polycyclic compound may be represented by Formula 1 below. The polycyclic compound may improve the light emitting efficiency of a blue light emitting region, and an organic electroluminescence device including the polycyclic compound may have improved blue light emission, high external quantum efficiency, and long life. The polycyclic compound may be used as a thermally activated delayed fluorescence material, which emits blue light, to improve the blue light emitting efficiency of the organic electroluminescence device.
