| 摘要 |
An exemplary embodiment of the present invention discloses a light emitting diode including a lower contact layer having a first edge, a second edge opposite to the first edge, a third edge connecting the first edge to the second edge, and a fourth edge opposite to the third edge, a mesa structure arranged on the lower contact layer, the mesa structure including an active layer and an upper contact layer, a first electrode pad arranged on the lower contact layer, a second electrode pad arranged on the mesa structure, a first lower extension and a second lower extension extending from the first electrode pad towards the second edge, distal ends of the first lower extension and the second lower extension being farther away from each other than front ends thereof contacting the first electrode pad, and a first upper extension, a second upper extension, and a third upper extension extending from the second electrode pad. In addition, the first upper extension and the second upper extension extend from the second electrode pad to enclose the first lower extension and the second lower extension, and the third upper extension extends to a region between the first lower extension and the second lower extension.
