Abstract
A TFT array having a plurality of gate lines and a plurality of drain lines formed on a transparent substrate. The gate lines intersect with the drain lines. TFT are formed at the intersections of the gate lines and the drain lines. An insulating film is formed on the drain lines and the drain electrodes of the TFTs. Pixel electrodes are formed, each overlapping the corresponding gate line and the corresponding drain line. The pixel electrode has a large area and thus, have a high opening ratio. The TFT array can, therefore, help to provide a liquid crystal display having high contrast.
