摘要：
A liquid crystal display device comprising a wiring line of a laminated structure over an insulating substrate. The laminated structure includes a first layer made of a first metal layer, and a second layer formed over the first layer and made of a second metal layer having the same principal component as that of the first metal layer but a different added element and/or a different composition. The first layer has a side end face of a right-tapered shape, whereas the second layer has a side end face set at a right angle or counter-tapered with respect to the substrate face.
