Abstract: A light-emitting device includes a light-emitting element having a light-emitting surface, and a plurality of protruding portions being separated from each other and disposed on the light-emitting surface. The protruding portions are transparent. Each of the protruding portions includes a light guide portion and a light distribution control portion. The light guide portion has a columnar configuration and is provided at a light-emitting surface side of the protruding portion. The light distribution control portion is provided on the light guide portion. The light distribution control portion is asymmetric with respect to a central axis of the light guide portion and has a tilted surface that is tilted with respect to the central axis.
