Abstract
A semiconductor light emitting device includes a light emitting chip that includes a semiconductor layer at a first surface. A transparent film is provided on the semiconductor layer and forms an interface therewith. A phosphor resin layer, including a resin and a phosphor, is provided on the transparent film. A refractive index of the transparent film is greater than a refractive index of the semiconductor layer.
