Semiconductor light emitting device
The present invention relates to a semiconductor light emitting device including: a substrate for element mounting; a wiring provided on the substrate; an LED element provided on the substrate and electrically connected to the wiring; an encapsulating resin layer for encapsulating the LED element; and a wavelength conversion layer which contains a phosphor material and converts a wavelength of light emitted by the LED element, in which the wavelength conversion layer is provided on an upper side of the LED element, and a diffusive reflection resin layer is provided in a state that side faces of the LED element are surrounded therewith, and an area at the LED element face side of the wavelength conversion layer is at least twice larger by area ratio than an area of light emitting area on an upper surface of the LED element.
