Abstract
There are provided a thin film transistor liquid crystal display device in which an aluminum layer and an ITO layer can be connected with simplicity and certainty and a fabricating process therefor. A thin film transistor liquid crystal display device comprising: a pair of substrates; a liquid crystal sandwiched therebetween; an aluminum layer formed on a surface in which the liquid crystal is held, of one substrate; an insulating layer covering the aluminum layer; a contact hole formed in the insulating layer so as to reach the aluminum layer; an indium tin oxide layer formed on the insulating layer including the inner surface of the contact hole; and a silicide layer lying between the indium tin oxide layer and the aluminum layer.
