Abstract

An organic light emitting diode display includes a substrate, a semiconductor layer disposed on the substrate, a first insulating layer which covers the semiconductor layer, a first conductive layer disposed on the first insulating layer, a second insulating layer which covers the first conductive layer, a second conductive layer disposed on the second insulating layer, a third insulating layer which covers the second conductive layer, a third conductive layer disposed on the third insulating layer, a first organic layer which covers the third conductive layer, and a fourth conductive layer disposed on the first organic layer, where the fourth conductive layer includes a lower layer, a middle layer, and an upper layer, and the lower layer is disposed between the first organic layer and the middle layer, and includes a transparent conductive oxidization film.
