Abstract

A light-emitting diode (LED) device and a method of producing the same are provided. The LED device comprises a first conductive layer, a second conductive layer, an active layer sandwiched between the first conductive layer and the second conductive layer and a first electrode in electrical contact with the first conductive layer. The first conductive layer has a laminate structure comprising a first conductive sub-layer, a current blocking layer, and a second conductive sub-layer. The first electrode comprises a first extended electrode in electrical contact with the first conductive sub-layer, and a second extended electrode in electrical contact with the second conductive sub-layer. The first conductive sub-layer and the second conductive sub-layer may have different depths.
