Abstract:
A light emitting device includes: a light emitting element, a wavelength conversion member disposed on an upper face of the light emitting element and having a lower face that has a larger area than the upper face of the light emitting element, a first light guide member extending from a lateral face of the light emitting element to the lower face of the wavelength conversion member, a light transmissive member disposed on an upper face of the wavelength conversion member and having a lower face that has a smaller area than the upper face of the wavelength conversion member, and a second light guide member extending from the upper face of the wavelength conversion member to a lateral face of the light transmissive member.
