ABSTRACT:
An active matrix liquid crystal display comprises a first substrate, a second substrate, and liquid crystal held therebetween. The first substrate includes on one surface, a plurality of gate lines, a plurality of drain lines crossing the gate lines, and transistors each disposed in the vicinity of crossing points between the gate lines and the drain lines. Source electrodes of the transistors are each connected to pixel electrodes each disposed in the vicinity of the source electrodes. The drain electrodes of the transistors are connected to one of a plurality of the drain lines while the gate electrodes of the transistors are connected to one of a plurality of the gate lines. The second substrate is disposed in such a manner as to face to the first substrate and to have facing electrodes on the surface facing to the pixel electrodes. In such a liquid crystal display, either a plurality of the gate lines or a plurality of the drain lines are made of a Cr alloy containing at least one kind selected from a group consisting of Mo, Nb, Ta and W.
