Abstract
The present invention relates to a light emitting device. According to the present invention, the light emitting device comprises a substrate, a plurality of light emitting cells disposed on the substrate, a first insulation layer disposed on each light emitting cell, an electrically conductive material disposed on the first insulation layer to couple two of the light emitting cells, and a second insulation layer disposed on the electrically conductive material. Each light emitting cell comprises a first semiconductor layer, a second semiconductor layer, and an inclined surface. The second insulation layer corresponds to a contour of each light emitting cell.
