Abstract:
1. An organic light emitting display device comprising: a substrate; a thin film transistor, comprising a semiconductor layer, a gate electrode, a source electrode, and a drain electrode; and a first electrode electrically coupled with any one of the source electrode and the drain electrode on the same layer, arranged on the substrate; an organic layer arranged on the first electrode and including at least an organic emission layer; and a second electrode arranged on the organic layer, wherein the source electrode, the drain electrode and the first electrode, comprise a reflective layer formed of a silver (Ag) alloy having a composition ratio of 0.1 to 0.3 atom % of samarium (Sm), of 0.1 to 0.5 atom % of terbium (Tb), 0.1 to 0.4 atom % of gold (Au), and 0.4 to 1.0 atom % of copper (Cu), below a transparent conductive layer.
