Abstract: A light emitting device including a contact layer, a blocking layer over the contact layer, a protection layer adjacent the blocking layer, a light emitter over the blocking layer, and an electrode layer coupled to the light emitter. The electrode layer overlaps the blocking layer and protection layer, and the blocking layer has an electrical conductivity that substantially blocks flow of current from the light emitter in a direction towards the contact layer. In addition, the protection layer may be conductive to allow current to flow to the light emitter or non-conductive to block current from flowing from the light emitter towards the contact layer.
