(57) [Problem] To provide a light-emitting element provided with a novel structure for directing lateral light generated in a light-emitting layer to the outside. SOLUTION: Irregularities 1a are processed on the surface of a first layer 1 and a second layer 2 having a refractive index different from that of the first layer is grown by embedding the concaves and convexes (or a crystal layer S as a basis for growth). The first crystal 10 is grown on the upper surface in an uneven shape, and the second crystal 20 having a different refractive index from the first crystal is grown). After forming these uneven refractive index interfaces 1a (10a), an element structure in which a semiconductor crystal layer including the light emitting layer A is laminated thereon is formed. As a result, the light in the horizontal direction generated in the light emitting layer is affected by the uneven refractive index interface and changes its direction. |
