Light-emitting diode and electronic device including the same

Abstract

The present disclosure provides a light-emitting diode, and an electronic device. Particularly, the present disclosure provides a light-emitting diode with improved color purity and current efficiency and optimized lifespan and an electronic device including thereof, by the inclusion of stack units vertically laminated to form a plurality of layers, and including a plurality of light-emission layers on each layer. One or more light-emission layers among the plurality of light-emission layers in an uppermost stack unit among the laminated stack units are thermally activated delayed fluorescence light-emission layers configured to emit thermally activated delayed fluorescence, and at least one stack unit below the uppermost stack unit includes at least one of a phosphorescence light-emission layer or a fluorescence light-emission layer.

Dependencies are inferred from the claim text.
