Abstract:
The light emitting device includes a light emitting element, a wavelength converter, and a light guider. 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. 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 includes first and second wavelength converter parts. The first wavelength converter part faces the element upper surface and has a first thickness. The second wavelength converter part does not face the element upper surface and has a second thickness thinner than the first thickness.
