Abstract
To provide a light-emitting device which can emit bright light without increasing the projected area of a light-emitting element and be manufactured with high yield. A light-emitting device of one embodiment of the present invention includes a plurality of projections; a first electrode formed along the plurality of projections; a layer containing a light-emitting organic compound formed along the plurality of projections and over the first electrode; and a second electrode formed along the plurality of projections and over the layer containing a light-emitting organic compound. Further, the plurality of projections each have a bottom surface having a side in contact with a bottom surface of an adjacent projection; a plurality of side surfaces each having a certain angle greater than 0° and less than or equal to 80° with respect to the bottom surface; and a vertex having a first continuously curved surface.
