Claim 0:
1. A manufacturing method of an organic light emitting diode display, the method comprising:
receiving a substrate on which a planarization layer is disposed on a thin film transistor;
forming a pixel electrode material layer including an upper material layer, an intermediate material layer including silver, and a lower material layer on the planarization layer;
forming an etch stop material layer including a compound having low reactivity with a fluorine-based gas on the upper material layer;
forming an etch stop layer by first patterning the etch stop material layer;
forming a pixel electrode including an upper layer, an immediate layer, and a lower layer by patterning the pixel electrode material layer;
forming an inorganic material layer for a partition on the etch stop layer;
forming the partition to expose an upper surface of the etch stop layer by patterning the inorganic material layer for the partition;
forming the etch stop layer to expose the upper surface of the pixel electrode by second patterning the etch stop layer;
forming an organic emission layer on an exposed portion of the upper surface of the pixel electrode; and
forming a common electrode on the organic emission layer and the partition.
