Abstract:
Disclosed is an organic light emitting display device. The organic light emitting display device includes a switching thin film transistor (TFT) that includes a lower gate, a source, and a drain formed on a substrate and on the same layer, a first gate insulating layer formed to cover the lower gate, the source, and the drain, an active layer formed on the first gate insulating layer, a conductive line formed to contact the source and the drain, a second gate insulating layer formed on the active layer, and an upper gate formed on the second gate insulating layer. The lower gate of the switching TFT is a light shield that blocks light from being irradiated onto the active layer.
