Abstract
A light emitting diode includes a first semiconductor layer, an active layer, and a second semiconductor layer sequentially stacked on a substrate, and a first electrode connected to the first semiconductor layer. The first electrode includes an edge electrode including first and second edge portions opposite to each other, and a line electrode including first and second line portions respectively extending from the first and second edge portions. The edge electrode has a closed loop-shape. A distance between the first line portion and the second edge portion is equal to or less than a quarter of a length of the first line portion. A distance between the second line portion and the first edge portion is equal to or less than a quarter of a length of the second line portion.
