Abstract
A system for displaying images. The system includes a thin film transistor (TFT) device including a first gate layer disposed on a first region of a substrate and covered by a first insulating layer. A first polysilicon active layer is disposed on the first insulating layer and a second polysilicon layer is disposed on a second region of the substrate. A second insulating layer covers both of the first and second polysilicon gate layers. Second and third gate layers are respectively disposed on the second insulating layer above the first and second polysilicon active layers. A method for fabricating a system for displaying images including the TFT device is also disclosed.
