Abstract
A first semiconductor light emitting device includes: a transparent substrate; a light emitting layer; and a roughened region. The transparent substrate has a first major surface and a second major surface, and is translucent to light in a first wavelength band. The light emitting layer is selectively provided in a first portion on the first major surface of the transparent substrate and configured to emit light in the first wavelength band. The roughened region is provided in a second portion different from the first portion on the first major surface. A second semiconductor light emitting device includes: a transparent substrate; a light emitting layer; a first electrode; and at least one groove. The groove is provided on the second major surface of the transparent substrate and extends from a first side face to a second side face opposing the first side face of the transparent substrate.
