Abstract
Provided are an organic light-emitting diode (OLED) and an organic light-emitting device including the same. The OLED includes a first electrode, an organic emissive layer which includes a plurality of convex curves or a plurality of concave curves in a light-emitting region and of which a slope of an inclined plane of an upper region with respect to a horizontal line dividing a height of the plurality of convex curves into halves is greater than a slope of an inclined plane of a lower region thereof, and a second electrode provided on the organic emissive layer. Accordingly, the OLED and the organic light-emitting device including the same are capable of improving current efficiency.
