发明名称 LIGHT EMITTING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a light emitting device having improved uniformity.SOLUTION: According to an embodiment, a light emitting device includes a mounting region, a plurality of semiconductor light emitting elements and a wavelength conversion layer. The mounting region includes a central part and an outside part outside the central part. The plurality of semiconductor light emitting elements are provided on the mounting region. The wavelength conversion layer covers the plurality of semiconductor light emitting elements and converts wavelength of light emitted from the plurality of semiconductor light emitting elements. A first distance between a top face of the wavelength conversion layer and the mounting region in a first region between two neighboring semiconductor light emitting elements among the plurality of semiconductor light emitting elements is longer at the outside part than at the central part.
