Abstract: A method of manufacturing a light emitting device, includes providing a light emitting element having an element upper surface, an element lower surface opposite to the element upper surface in a thickness direction of the light emitting element, and an element side surface between the element upper surface and the element lower surface. A wavelength converter having a converter lower surface is provided. The wavelength converter is joined to the light emitting element using an adhesive so 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 viewed along the thickness direction. The adhesive covers the element side surface and the exposed region.

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.

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.
