Claim:
1. A method for manufacturing an organic light emitting display comprising: forming a first etching stopper film and a first buffer layer on a first substrate, and forming a transistor-organic light emitting diode array having a transistor in each of pixels defined in a matrix form and an organic light emitting diode connected to the transistor in an active region of the first buffer layer; forming a second etching stopper film and a second buffer layer on a second substrate and forming a touch electrode array in an active region of the second buffer layer; forming a touch pad portion in a part of a dead region of the second buffer layer, wherein the touch pad portion comprises a plurality of touch pads and each of the touch pads comprises a metal pad layer and a transparent electrode pad layer connected to each other via a plurality of first contact holes in a first insulating film; forming a dummy pad portion in a dead region of the first buffer layer, wherein the dummy pad portion comprises a plurality of dummy pads, each dummy pad corresponding to each touch pad; and applying a sealant including a conductive ball to the touch pad portion or the dummy pad portion, attaching an adhesive layer to the touch electrode array or the transistor-organic light emitting diode array and joining the first substrate to the second substrate.
