Abstract:
A light emitting element includes an n-side semiconductor layer, a p-side semiconductor layer, a plurality of holes, a first p-electrode, a second p-electrode and an n-electrode. The n-side semiconductor layer has a hexagonal shape in plan view. The p-side semiconductor layer has a hexagonal shape in plan view and provided over the n-side semiconductor layer. The holes are arranged in the p-side semiconductor layer so that the n-side semiconductor layer is exposed through the plurality of holes. The first p-electrode is in contact with the p-side semiconductor layer. The second p-electrode is arranged on the first p-electrode adjacent to a corner corresponding to one of vertices of the hexagonal shape. The second p-electrode has sides that are respectively parallel to sides defining the corner in plan view. The n-electrode is arranged over the first p-electrode and is electrically connected to the n-side semiconductor layer through the plurality of holes.
