Abstract: An organic light emitting display device includes a driving TFT on the substrate, a switching TFT on the substrate, and an organic light emitting diode. The driving TFT includes a first active layer formed of poly-Si, and at least a first part of an interlayer insulation layer on the first active layer. The interlayer insulation layer is formed of a first material including hydrogen. The switching TFT includes a second active layer, at least a second part of the interlayer insulation layer between the first active layer and the second active layer, and at least a part of a gate insulation layer between the second part of the interlayer insulation layer and the second active layer. The gate insulation layer is formed from a second material different from the first material and blocking diffusion of hydrogen from the interlayer insulation layer to the second active layer.
