摘要：An organic light emitting display device includes a driving thin film transistor (TFT), the driving thin film TFT includes a lower gate, a source, and a drain on a substrate and on the same layer; a first gate insulating layer covering the lower gate, the source, and the drain; an active layer on the first gate insulating layer; a conductive line contacting the source and the drain; a second gate insulating layer on the active layer; and an upper gate on the second gate insulating layer, wherein the lower gate of the driving TFT is a light shield that blocks light from being irradiated onto the active layer, and the lower gate and the source include the same metal.
