Abstract: A liquid crystal display unit in which at least one of a gate electrode line, a drain electrode line, and a gate electrode and a source/drain electrode of a TFT formed on a substrate is composed of a metal Nb or an alloy material of Nb. Glass is used as the substrate, and the size thereof is preferably 300 mm or longer on one side and 1 mm or less in thickness. In order to provide a low wiring resistance to produce a high resolution and large size TFT panel, the resistivity of the metal Nb or the alloy material thereof is preferably 25 .mu..OMEGA.cm or less, and the film stress of Nb or the alloy material thereof on the glass substrate is 400 MPa or less.

Abstract: A liquid crystal display device can be fabricated through simplified processes, and provide a high product yield and excellent picture displaying characteristic. The liquid crystal display device includes a first substrate having thereon a plurality of drain wirings, a plurality of gate wirings crossing the plurality of drain wirings in a matrix array, a plurality of thin film transistors disposed in the vicinity of these crossings, and a plurality of pixel electrodes connected to the thin film transistors, respectively. A second substrate is disposed in opposing relation to the first substrate, and a liquid crystal layer is sandwiched between these substrates. Each terminal portion of the plurality of drain wirings and plurality of gate wirings is constructed with a metallic film covered with a transparent conductive film.

Abstract: A matrix for magnetic separators which comprises wire or ribbon of a crystalline magnetic alloy having a fine-grained structure and a supersaturated solid solution structure.
