Abstract:
1. A light-emitting diode element, comprising: a first semiconductor layer of a first conductivity type which has a principal surface and a rear surface; a second semiconductor layer of a second conductivity type which is provided in a first region of the principal surface of the first semiconductor layer; an active layer interposed between the first semiconductor layer and the second semiconductor layer; a first electrode provided on a surface of the second semiconductor layer; the first semiconductor layer is formed on the active layer; a second electrode provided in a second region of the principal surface of the first semiconductor layer; and a conductive layer that is arranged such that, in the rear surface of the first semiconductor layer, when viewed from a direction perpendicular to the rear surface, the conductive layer covers a third region lying between the first electrode and the second electrode, a fourth region which is adjacent to the third region and which overlaps at least part of the second electrode, and a fifth region which is adjacent to the third region and which overlaps part of the first electrode, wherein the conductive layer is in contact with the first semiconductor layer, the first semiconductor layer includes, in the rear surface of the first semiconductor layer, a sixth region which is not covered with the conductive layer and which overlaps another part of the first electrode when viewed from a direction perpendicular to the rear surface, and the first semiconductor layer of the first conductivity type is not provided with an electrode penetrating between the principal surface and the rear surface.
