Abstract:
1. A light-emitting device, comprising: a base; a light-emitting element placed on the base; and a wavelength converting layer that is placed on the base and covers the light-emitting element, wherein the light-emitting element and the wavelength converting layer are in direct physical contact with each other, the wavelength converting layer includes a single wavelength converting portion that converts a wavelength of light from the light-emitting element, and a plurality of light guide portions made of a light-transmitting material, each of which is entirely surrounded by the single wavelength converting portion when viewed from a light-emitting direction, the plurality of light guide portions include at least one light guide portion that does not extend through two different surfaces of the wavelength converting layer, sides of each of the plurality of light guide portions are surrounded by the single wavelength converting portion, each of the light guide portions is free from a wavelength converting material, and extends to a light extraction side of the wavelength converting layer, the single wavelength converting portion is made of a light-transmitting base material and a wavelength converting material dispersed in the light-transmitting base material, and the light-transmitting material for forming the light guide portions has a refractive index higher than a refractive index of the light-transmitting base material.
