Abstract
A back panel for a flat panel display apparatus includes: a pixel electrode disposed on a substrate; a first gate electrode layer of a thin-film transistor (TFT) disposed on the substrate; a second gate electrode layer disposed on the first gate electrode layer and including a semiconductor material; a third gate electrode layer disposed on the second gate electrode layer and including a metal material; a first insulating layer disposed on the third gate electrode layer; an active layer disposed on the first insulating layer and including a transparent conductive oxide semiconductor; a second insulating layer disposed on the active layer; source and drain electrodes disposed connected to the active layer through the second insulating layer; and a third insulating layer covering the source and drain electrodes. The first gate electrode layer and the pixel electrode include a transparent conductive oxide.
