Abstract
A method of manufacturing a light-emitting element includes: forming a plurality of rod-shaped layered structures by performing steps including: forming a first conductive-type semiconductor layer on a substrate, forming, on the first conductive-type semiconductor layer, an insulating film defining a plurality of openings and a plurality of rods of a first conductive-type semiconductor, wherein each of the rods is disposed through a respective one of the plurality of openings, forming a light-emitting layer covering outer surfaces of the plurality of rods, and forming a second conductive-type semiconductor layer covering outer surfaces of the light-emitting layer; forming a photoresist pattern covering a portion of the plurality of the rod-shaped layered structures; removing a portion of the insulating film in a region that is not covered by the photoresist pattern; and removing a portion of the plurality of rod-shaped layered structures in the region that is not covered by the photoresist pattern.
