Abstract:
1. An organic light emitting display apparatus comprising: a substrate; an active layer on the substrate; a gate electrode insulated from the active layer and composed of a first conductive layer comprising ITO, a second conductive layer on the first conductive layer, a third conductive layer on the second conductive layer and comprising ITO, and a fourth conductive layer on the third conductive layer and comprising IZO or AZO; a pixel electrode formed in the same layer level as the gate electrode and composed of a first electrode layer comprising ITO, a second electrode layer on the first electrode layer, a third electrode layer on the second electrode layer and comprising ITO, and a fourth electrode layer on the third electrode layer and comprising IZO or AZO; a source electrode and a drain electrode, the source and drain electrodes being insulated from the gate electrode and electrically coupled to the active layer; an intermediate layer on the pixel electrode and comprising an organic light emitting layer; and a counter electrode on the intermediate layer, wherein the pixel electrode is electrically coupled to the source electrode or the drain electrode.
