Abstract
According to one embodiment, a semiconductor light emitting device includes a stacked body, a first electrode, a second electrode, a reflective layer, a first metal pillar, a second metal pillar, and a sealing unit. The stacked body includes first and second semiconductor layers, and a light emitting unit. The light emitting unit is provided between the second portion and the second semiconductor layer. The first electrode is provided on the first semiconductor layer. The second electrode is provided on the second semiconductor layer. The reflective layer covers a side surface of the stacked body and insulative and reflective. The first metal pillar is electrically connected to the first electrode. The second metal pillar is electrically connected to the second electrode. The sealing unit seals the first and second metal pillars to leave end portions of the first and second metal pillars exposed.
