Abstract
A TFT-driven display device includes an upper substrate and a lower substrate facing each other, multiple TFTs disposed on a side of the lower substrate facing the upper substrate, and a metal layer disposed on a side of the upper substrate facing the lower substrate. The metal layer includes multiple horizontal metal wirings extending in a direction of scanning lines and including portions overlapping with an active layer of the TFTs in the light transmission direction, the overlapping portions have a pattern width less than that of other portions that do not overlap with the active layer. A photo-leakage current caused by light reflected by the metal layer may be reduced, because no portion of the metal layer is provided in the position opposed to the active layer of the TFTs located on a TFT array substrate.
