Abstract:
1. A semiconductor light emitting diode having a semiconductor layer including a light emitting portion, and a pad electrode located on the semiconductor layer, comprising: between the semiconductor layer and the pad electrode, a reflective portion including a light transmitting insulating layer serving as a current blocking layer located on the semiconductor layer, and a reflective layer located on the light transmitting insulating layer; a contact portion formed from an ohmic electrode in contact with the reflective portion, located on the semiconductor layer; and a conductive hard film between the reflective layer and the pad electrode, wherein the conductive hard film has HV×t>630, where Vickers hardness is HV (Hv) and the thickness is t (μm), which the conductive hard film has a Vickers hardness HV of 1500 Hv or more, and has a thickness t of 2 μm or less.
