Abstract
A method of manufacturing an organic light emitting display device, the method includes forming a thin film transistor (TFT) in an active area of a substrate and forming a signal pad and a first pad electrode, connected to the signal pad, in a pad area of the substrate, forming a passivation layer on the TFT and the first pad electrode, forming a planarization layer on the passivation layer, removing a certain region of the passivation layer to simultaneously form an area, through which the TFT is exposed to the outside, and an area through which the first pad electrode is exposed to the outside, forming a first anode electrode connected to the TFT, a first auxiliary electrode spaced apart from the first anode electrode, and a second pad electrode that is connected to the first pad electrode and covers the exposed first pad electrode; and forming a second anode electrode, covering a top and a side surface of the first anode electrode, and a second auxiliary electrode covering a top and a side surface of the first auxiliary electrode.
