  • Patent number: 11923479
    Abstract: A light-emitting element and an electronic apparatus capable of reducing the element area and realizing a stable electrical connection. A light-emitting element according to the present technology includes a first semiconductor layer, a light-emitting layer, and a second semiconductor layer laminated in this order, and a light-emitting surface, a non-light-emitting surface, and a side surface connecting the light-emitting surface and the non-light-emitting surface. The side surface is inclined. A first electrode is in a concave portion in the light-emitting surface at a periphery of the first semiconductor layer. A second electrode is on a non-light-emitting surface side of the laminate. A third electrode is on the non-light-emitting surface side of the laminate and is insulated from the second electrode. The side wiring electrically connects the first electrode and the third electrode via the side surface.

  • Publication number: 20230096713
    Abstract: A light-emitting element including: a stacked body; a light-emitting surface; and a reflecting body. The stacked body includes a first semiconductor layer, a second semiconductor layer, and an active layer between the first and second semiconductor layers, and has first and second surfaces on a side opposite to the active layer, and a circumferential surface that connects the first surface and the second surface and includes an end surface of the active layer, a groove formed in the first semiconductor layer from the first surface toward the active layer, having a depth such that the groove is separated from the active layer, and extending in a direction parallel to the first surface. The light-emitting surface is positioned on the first surface on a side opposite to the active layer and emits light generated in the active layer. The reflecting body reflects light emitted from the end surface toward the groove.
