ABSTRACT:
A flat panel display device (FPD) and fabricating method thereof are disclosed, which reduce the number of masks during fabrication and prevent electrochemical corrosion problems. In the FPD, a cell area and a pad area are defined on a substrate. A storage electrode traverses an active layer in parallel to a gate line. Source and drain regions of the active layer in the vicinity of both sides of a gate electrode are not formed below the storage electrode. An insulating interlayer over the substrate has first and second contact holes on the source and drain regions, respectively. A source electrode contacts the source region via a first contact hole and a drain electrode contacts the drain region via a second contact hole to directly contact a pixel electrode. A protective layer is disposed over the substrate including the pixel electrode.
