Abstract:
A method of manufacturing an organic light emitting display device can include providing a source electrode, a drain electrode and a signal pad on a substrate; providing a passivation layer on the source electrode, the drain electrode and the signal pad, providing a planarization layer on the passivation layer; providing a anode electrode connected with the source electrode or drain electrode, and providing an auxiliary electrode spaced apart from the anode electrode; providing a contact hole for exposing the signal pad by removing a predetermined portion of the passivation layer; providing a bank on one side and the other side of the anode electrode and one side and the other side of the auxiliary electrode; providing an organic emitting layer on the anode electrode; and providing a cathode electrode connected with the auxiliary electrode and provided on the organic emitting layer, in which the signal pad includes a lower signal pad, a central signal pad and an upper signal pad, and the central signal pad is surrounded by the lower signal pad, the upper signal pad and the passivation layer.
