Point emission type light emitting element and concentrating point emission type light emitting element |
摘要 |
To provide a point emission type light emitting element that restricts the light emitting area within a sufficiently tiny region and can be manufactured at a low cost, the point emission type light emitting element is a light emitting element that has stripe ridge comprising an n-type layer, an active layer and a p-type layer that are formed from semiconductors on a substrate, so as to emit light from one end face of the stripe ridge, wherein the stripe ridge has a protruding portion on the end face described above and the surface of the light emitting element is covered with an shading film except for the tip of the protruding portion.
