Abstract
There is provided a semiconductor light-emitting device including a light-emitting edge, an opposite edge, and a first conductive layer that includes a current narrowing structure having a longitudinal direction along one direction from the opposite edge to the light-emitting edge. An active layer is between the first conductive layer and a second conductive layer which respectively come into contact with the first conductive layer and the second conductive layer. The current narrowing structure includes a spread area such that a width of the spread area in a direction along a surface of the first conductive layer widens from a predetermined position toward the light-emitting edge in the one direction. The first electrode layer includes an electrode area on at least the spread area such that a width thereof in the direction along the surface of the first conductive layer becomes smaller than the width of the spread area.
