An organic light emitting display device including an anode having a multi-layer structure which can be manufactured using a simple process, has good hole transfer properties and high reflectivity, and prevents energy loss due to a drop in voltage. The organic light emitting display device includes a substrate, a thin film transistor formed on the substrate and including source and drain electrodes, a first anode patterned simultaneously with the source and drain electrodes of the thin film transistor, formed integrally with the source or drain electrode, and made out of a conductive material having a low resistance, a second anode formed on the first anode, and made out of a conductive material having a high work function, an organic layer formed on the second anode and a cathode formed on the organic layer.
