Abstract
A display device having a substrate; a first thin film transistor (TFT) on the substrate, the first TFT having a first active layer, a first gate insulator, and a first gate electrode; a second TFT on the substrate, the second TFT having a second active layer, a second gate insulator and a second gate electrode. The first gate insulator is disposed between the first gate electrode and the first active layer, and the first gate insulator is in contact with the first active layer. The second gate insulator is disposed between the second gate electrode and the second active layer, and the second gate insulator is in contact with the second active layer. The first active layer is a different material than the second active layer, and a hydrogen concentration of the second gate insulator is less than a hydrogen concentration of the first gate insulator.
