ABSTRACT:
The present invention relates to a light emitting element with arrayed cells, a method of manufacturing the same, and a light emitting device using the same. The present invention provides a light emitting element including a light emitting cell block with a plurality of light emitting cells connected in series or parallel on a single substrate, and a method of manufacturing the same, wherein each of the plurality of light emitting cells includes an N-type semiconductor layer and a P-type semiconductor layer, and the N-type semiconductor layer of one light emitting cell is electrically connected to the P-type semiconductor layer of another adjacent light emitting cell. Further, the present invention provides a light emitting device including a light emitting element with a plurality of light emitting cells connected in series. Accordingly, it is possible to simplify a manufacturing process of a light emitting device for illumination capable of being used with a household AC power source, to decrease a fraction defective occurring in manufacturing a light emitting device for illumination, and to mass-produce the light emitting device for illumination. Further, there is an advantage in that DC driving efficiency can be enhanced in an AC operation by installing a predetermined rectifying circuit outside the light emitting element.
