An organic light-emitting device is constructed with an anode provided with a reflective metal layer, a transparent conductive layer, and a reflective metal oxide layer interposed therebetween, a cathode, and an organic functional layer interposed between the transparent conductive layer of the anode and the cathode, and provided with at least an organic emission layer. With this configuration, the reflective anode has high reflectivity, the reflectivity thereof is not substantially changed depending on wavelengths, and the reflective anode is free from defects caused by a galvanic phenomenon.
