Abstract
A reflective electrode, a method of manufacturing the reflective electrode, and an organic light emitting diode display including the reflective electrode are disclosed. The reflective electrode includes a first transparent conductive layer formed of a transparent conductive material, a reflective layer disposed on the first transparent conductive layer and including a plurality of grains formed of a reflective material, and a second transparent conductive layer disposed on the reflective layer and formed of a transparent conductive material. The adjacent grains are spaced from each other.
