Abstract:
A light emitting device includes a light emitting element, a wavelength converter, a light transmissive member, a light guider, and a light transmitting layer. The light emitting element has an element upper surface, an element lower surface, and an element side surface. The wavelength converter has a converter lower surface. The wavelength is provided to be connected to the light emitting element such that the converter lower surface faces the element upper surface. The converter lower surface has an exposed region that does not face the element upper surface. The light guider guides light from the light emitting element to the wavelength converter. The light guider covers the element side surface and the exposed region. The wavelength converter has a converter upper surface. The light transmitting layer has a layer lower surface facing the converter upper surface. The converter upper surface is smaller than the layer lower surface.
