Abstract
A passivation layer formed over and under a first pixel electrode is provided to prevent corrosion of the first pixel electrode of an organic light emitting diode (OLED) display device. The OLED display device includes: a substrate, a first passivation layer disposed on the substrate, a first pixel electrode disposed over the first passivation layer, a second passivation layer disposed over the first pixel electrode, a second pixel electrode disposed over the second passivation layer, an organic layer including an emission layer disposed over the second pixel electrode, and a counter electrode disposed over the organic layer. Each of the first and second passivation layers is formed of one selected from the group consisting of NiCr, Al2O3, TiO2, ZnO and PbO2.
