Abstract:
An organic light emitting diode display including: a substrate; a TFT on the substrate; a planarization layer on the TFT; a pixel electrode on the planarization layer, wherein the pixel electrode includes upper and lower layers including a transparent conductive oxide and an intermediate layer including silver; an etch stop layer on the pixel electrode, wherein an upper surface of the pixel electrode is exposed by the etch stop layer; a partition on the etch stop layer, wherein the upper surface of the pixel electrode is exposed by the partition; an organic emission layer on the upper surface of the pixel electrode where the upper surface of the pixel electrode is exposed by the etch stop layer and the partition; and a common electrode on the organic emission layer and the partition, wherein the etch stop layer covers an edge and a side surface of the pixel electrode.
