    Abstract: A light-emitting diode includes a substrate, and a light-emitting structure disposed on the substrate. The light-emitting structure includes a first conductivity-type semiconductor layer, an active layer, and a second conductivity-type semiconductor layer. A transparent electrode layer including concave portions and convex portions is disposed on the second conductivity-type semiconductor layer. Micro-lenses are disposed on the transparent electrode layer and completely cover the concave portions, and only partially cover the convex portions that are disposed between the micro-lenses.
