Abstract
A semiconductor light emitting element is disclosed. The element includes a substrate including a first surface, a second surface opposite to the first surface, and a side surface that connects the first surface and the second surface; a semiconductor layer formed on the first surface of the substrate and configured to generate light; and a light reflective layer formed on the second surface of the substrate to cover an entire region of the second surface of the substrate and configured to reflect the light generated by the semiconductor layer toward the semiconductor layer. A modified layer, which has a physical property different from that of the other portion of the substrate, is formed on the side surface of the substrate to be spaced apart from the first surface toward the second surface by altering a material forming the substrate.
