LIGHT EMITTING ELEMENT

A light emitting element includes: a first conductivity type semiconductor rod having a plurality of side surfaces arranged to form a polygonal column shape; an active layer formed of a semiconductor and covering the side surfaces; and a second conductive type semiconductor layer covering the active layer. The active layer includes a plurality of well layers respectively disposed over at least two adjacent side surfaces among the plurality of side surfaces. Adjacent well layers among the plurality of well layers are separated from each other along a ridge line where the at least two adjacent side surfaces are in contact with each other. The active layer further includes a ridge portion formed of a semiconductor and disposed on the ridge line, the ridge portion connecting the adjacent well layers. A bandgap of the ridge portion is wider than a bandgap of each of the plurality of well layers.
