Abstract
A light-emitting device includes: a semiconductor stacked body comprising a first conductive semiconductor layer, an active layer, and a second conductive semiconductor layer stacked in this order; a first insulating film that covers the active layer and the second conductive semiconductor layer; a first conductive layer that continuously surrounds a lateral surface of the first conductive semiconductor layer that is exposed from the first insulating film; a second insulating film that covers the first conductive layer, the active layer, and the second conductive semiconductor layer and that has a hole disposed above the second conductive semiconductor layer; and a second conductive layer that continuously covers, via the second insulating film, an end portion of the first conductive layer located in proximity to an end portion of the second conductive semiconductor layer, wherein the second conductive layer is connected to an upper surface of the second conductive semiconductor layer through the hole.
