发明名称 LIGHT EMITTING DEVICE
摘要 Provided is a light emitting device capable of further improving light extraction efficiency while reducing leakage of wavelength unconverted light or color unevenness of the light. The light emitting device includes: a base member; a light emitting element mounted on the base member; a light reflecting member disposed at a side surface side of the light emitting element; and a light-transmissive stacked layer covering at least an upper surface of the light emitting element, wherein the light-transmissive stacked layer includes a first light-transmissive layer, a first wavelength conversion layer disposed on the first light-transmissive layer, a second light-transmissive layer disposed on the first wavelength conversion layer, and a second wavelength conversion layer disposed on the second light-transmissive layer.
