Abstract
The semiconductor light-emitting element includes: a substrate; a semiconductor layer that is provided over the substrate; a first electrode that is provided in contact with part of an upper surface of the semiconductor layer and includes a current supply part; a second electrode that is provided in part of a region vertically below a region where the current supply part is not provided, that is in contact with part of the semiconductor layer; and a first current blocking layer that is provided in a region including a region vertically below the current supply part and that is in contact with part of the semiconductor layer, wherein a contact resistance at an interface between the first current blocking layer and the semiconductor layer is higher than that at an interface between the second electrode and the semiconductor layer.
