1. A light emitting device comprising:
a substrate;
a light emitting element disposed on the substrate, the light emitting element being configured to emit first light;
a first wavelength conversion member disposed on the light emitting element and having a lower surface bonded to the light emitting element, an upper surface opposite the lower surface, and a lateral surface that meets the upper surface, the first wavelength conversion member being configured to emit second light when excited by the first light;
a first light reflecting member disposed on an upper surface of the substrate and covering lateral surfaces of the light emitting element;
a second wavelength conversion member disposed on the first light reflecting member, on the upper surface of the substrate, and on the lateral surface of the first wavelength conversion member without covering the upper surface of the first wavelength conversion member, the second wavelength conversion member being configured to emit third light when excited by at least one of the first light and the second light.
