Abstract
A semiconductor light emitting device includes a substrate; a plurality of light emitting cells disposed on the top surface of the substrate, the light emitting cells each having an active layer; a plurality of connection parts formed on the substrate with the light emitting cells formed thereon to connect the light emitting cells in a parallel or series-parallel configuration; and an insulation layer formed on the surface of the light emitting cell to prevent an undesired connection between the connection parts and the light emitting cell. The light emitting cells comprise at least one defective light emitting cell, and at least one of the connection parts related to the defective light emitting cell is disconnected.
