Abstract:
1. A method of manufacturing an organic light emitting display device, the method comprising: forming a first conductive layer and a second conductive layer on the first conductive layer, the first conductive layer being formed on a substrate; forming a patterned photoresist layer on a first area of the second conductive layer corresponding to where a gate electrode is to be formed and on a second area of the second conductive layer corresponding to where a pixel electrode is to be formed, wherein the patterned photoresist layer has a greater thickness at the first area than at the second area; patterning the first conductive layer and the second conductive layer by removing portions of the first conductive layer and the second conductive layer not covered by the patterned photoresist layer, and removing the patterned photoresist layer on the second area; and removing the second conductive layer of the second area to form the pixel electrode and removing the patterned photoresist layer remaining on the first area to form the gate electrode, wherein removing the second conductive layer of the second area to form the pixel electrode and removing the patterned photoresist layer remaining on the first area to form the gate electrode is performed using the same etching process.
