A layered semiconductor light emitting device includes a plurality of semiconductor light emitting elements each of which includes a light emitting region that converts electricity into light and emits the light. The semiconductor light emitting elements are layered in a layering direction perpendicular to the light emitting regions, and are bonded to each other via a planarizing layer having electrical insulation property. The planarizing layer includes a first planarizing region disposed above or below the light emitting regions of the semiconductor light emitting elements in the layering direction and formed of a first planarizing film having higher refractive index than air, and a second planarizing region other than the first planarizing region and formed of a second planarizing film having lower refractive index than the first planarizing film. In the layering direction, the upper semiconductor light emitting element transmits light emitted by the lower semiconductor light emitting element. |
