    摘要： According to one embodiment, a light emitting device includes a semiconductor light emitting element, a mounting member, a first wavelength conversion layer, and a first transparent layer. The semiconductor light emitting element emits a first light. The semiconductor light emitting element is placed on the mounting member. The first wavelength conversion layer is provided between the semiconductor light emitting element and the mounting member in contact with the mounting member. The first wavelength conversion layer absorbs the first light and emits a second light having a wavelength longer than a wavelength of the first light. The first transparent layer is provided between the semiconductor light emitting element and the first wavelength conversion layer in contact with the semiconductor light emitting element and the first wavelength conversion layer. The first transparent layer is transparent to the first light and the second light.
