Abstract:
1. A semiconductor light emitting device comprising: a light emitting unit including a first semiconductor layer, a light-emitting layer, and a second semiconductor layer, the first semiconductor layer having a first conductivity type and having a first portion and a second portion, the light-emitting layer provided on the first portion, the second semiconductor layer having a second conductivity type and provided on the light-emitting layer; a first electrode provided on the second portion and electrically connected to the first semiconductor layer; a second electrode provided on the second semiconductor layer and electrically connected to the second semiconductor layer; a first metal pillar electrically connected to the first electrode, extending in a first direction from the first semiconductor layer to the second semiconductor layer, and having an end not parallel to the first direction; a second metal pillar electrically connected to the second electrode, extending in the first direction, and having an end not parallel to the first direction; a sealing unit for sealing the first metal pillar and the second metal pillar, the sealing unit exposing the end of the first metal pillar and the end of the second metal pillar; a rectifying element provided below the first semiconductor layer, including a rectifying unit having at least one part not overlapping with the light emitting unit when projected onto a plane intersecting with the first direction; a first interconnection for electrically connecting the first electrode to one end of the rectifying unit; a second interconnection for electrically connecting the second electrode to another end of the rectifying unit; and a wavelength conversion layer provided under the first semiconductor layer, covering the light emitting unit and the rectifying unit, absorbing at least one part of a first light emitted from the light emitting unit, and emitting a second light having a wavelength different from a wavelength of the first light.
