Abstract
Disclosed is a light-emitting diode element including a first semiconductor layer of a first conductivity type, a second semiconductor layer of a second conductivity type, an active layer. A first electrode is provided on a surface of the second semiconductor layer. A second electrode is provided in a second region of the principal surface of the first semiconductor layer. A conductive layer is arranged such that the conductive layer covers a third region, a fourth region, and a fifth region in the rear surface of the first semiconductor layer. In the rear surface of the first semiconductor layer, the first semiconductor layer includes a sixth region which is not covered with the conductive layer and which overlaps another part of the first electrode. The first semiconductor layer is not provided with a through electrode.
