ABSTRACT:
A TFT array has a plurality of gate lines and a plurality of drain lines formed on a transparent insulating substrate. The gate lines intersect with the drain lines. TFTs are formed at the intersections of the gate lines and the drain lines. An opaque film is formed above the gate lines, the drain lines, and the TFTs, allowing no passage of light passing through the gaps between the transparent electrode, on the one hand, and the gate and drain lines, on the other hand. Therefore, when the TFT array is incorporated into a liquid-crystal display, the display will display high-contrast images.
