Provided is an organic light emitting diode (OLED) including a substrate, a first electrode, a second electrode, and an organic layer disposed between the first and second electrodes. The first electrode includes an aluminum (Al)-based reflective film and a transparent conductive film that contacts the Al-based reflective film. The Al-based reflective film includes aluminum, a first element and nickel (Ni). In this structure, galvanic corrosion, which occurs due to a potential difference between electrodes, may not occur between the Al-based reflective film 5 a and the transparent conductive film 5 b . Accordingly, deterioration of the quality of OLED is prevented. |
