Organic light emitting diode display that includes layer for reducing oxidation of common electrode

摘要

An organic light emitting diode display according to an exemplary embodiment includes a substrate, a pixel electrode on the substrate, an organic emission layer on the pixel electrode, a common electrode on the organic emission layer, a cover layer on the common electrode, an oxidation reducing layer on the cover layer, and a thin film encapsulation layer covering the oxidation reducing layer, the oxidation reducing layer being configured to reduce oxidation of the common electrode, the oxidation reducing layer being separated from the common electrode. The oxidation reducing layer may include at least one of a dummy common electrode, an ultraviolet ray (UV) blocking layer, and a buffer layer.
