Abstract
A light emitting device having a plurality of light emitting cells is disclosed. The light emitting device comprises a substrate; a plurality of light emitting cells positioned on the substrate to be spaced apart from one another, each of the light emitting cells comprising a p-type lower semiconductor layer, an active layer and an n-type upper semiconductor layer; p-electrodes positioned to be spaced apart from one another between the substrate and the light emitting cells, the respective p-electrodes being electrically connected to the corresponding lower semiconductor layers, each of the p-electrodes having an extension extending toward adjacent one of the light emitting cells; n-electrodes disposed on upper surfaces of the respective light emitting cells, wherein a contact surface of each of the n-electrodes electrically contacting with each light emitting cell exists both sides of any straight line that bisects the light emitting cell across the center of the upper surface of the light emitting cell; a side insulating layer for covering sides of the light emitting cells; and wires for connecting the p-electrodes and the n-electrodes, the wires being spaced apart from the sides of the light emitting cells by the side insulating layer.
