Flat panel display device with simplified efficient structure and method of manufacturing the same
First Claim
1. A flat panel display device comprising:
- a first thin-film transistor comprising a first active layer, a first insulation layer disposed on the first active layer, and a first gate electrode disposed on the first insulation layer;
a second thin-film transistor comprising a second active layer, wherein the first insulation layer is disposed on the second active layer,a second insulation layer disposed on and contacting the first insulation layer, and a second gate electrode disposed on the second insulation layer, and electrically connected to the first thin-film transistor;
a pixel electrode disposed to overlap the entire second active layer and the entire second gate electrode and contact a source region or a drain region; and
a capacitor electrically connected to the first thin-film transistor and the second thin-film transistor.

Abstract
Provided are a flat panel display device and a method of manufacturing the same. The flat panel display device includes a first thin-film transistor including a first active layer, a first insulation layer disposed on the first active layer, and a first gate electrode disposed on the first insulation layer; a second thin-film transistor including a second active layer, the first insulation layer disposed on the second active layer, a second insulation layer disposed on the first insulation layer, and a second gate electrode disposed on the second insulation layer, and electrically connected to the first thin-film transistor; and a capacitor electrically connected to the first thin-film transistor and the second thin-film transistor. In the structure as described above, since different numbers of insulation layers are interposed between active layers and gate electrode in each of the first thin-film transistor and the second thin-film transistor, threshold voltages of the first thin-film transistor and the second thin-film transistor are significantly different from each other, and thus it becomes easy to control the threshold voltages of the first thin-film transistor and the second thin-film transistor.
