A semiconductor light emitting device includes a light emitting unit, a first and second conductive pillar, a sealing unit, a translucent layer, and a wavelength conversion layer. The light emitting unit includes a first and second semiconductor layer and a light emitting layer. The first semiconductor layer has a first and second major surface. The first major surface has a first and second portion. The second major surface is opposed the first major surface and has a third and fourth portion. The light emitting layer is provided on the first portion. The second semiconductor layer is provided on the light emitting layer. The first conductive pillar is provided on the second portion. The second conductive pillar is provided on the second semiconductor layer. The translucent layer is provided on the fourth portion. The wavelength conversion layer is provided on the third portion and on the translucent layer.
