Patent ID: 10333029

Abstract:
An embodiment relates to a light-emitting element capable of reducing the driving voltage and improving the optical output, comprising: a support substrate; a light-emitting structure which is arranged on the support substrate, and which comprises a first semiconductor layer, an active layer, and a second semiconductor layer; a plurality of connection grooves comprising bottom surfaces, which expose the second semiconductor layer through removal of the light-emitting structure, and side surfaces, which expose the first semiconductor layer, the active layer, and the second semiconductor layer; a first electrode arranged on the light-emitting structure so as to contact the first semiconductor layer, the first electrode comprising a first electrode pattern, which has ends extending to the peripheries of the connection grooves, and a second electrode pattern, which is arranged on the first electrode pattern; a contact electrode extending to the upper surface of the first semiconductor layer so as to surround the bottom and side surfaces of the connection grooves; a second electrode comprising a bonding electrode connected to a plurality of the contact electrodes; and an insulating pattern arranged between the first electrode and the second electrode.
