(57) [Problem] To simplify the patterning process of wirings and electrodes, to secure the connection stability at the terminals of wirings, and to improve the reliability of products. A gate wiring (electrode) is provided on an inner surface of an insulating substrate. 2, an active matrix substrate on which a gate insulating layer 4, a semiconductor layer 5, a contact layer 6, source and drain wirings 8, 9, a passivation layer 10, and a pixel electrode 11 are formed, and a color filter layer 1 on an inner surface of an insulating substrate 12. 4, a color filter substrate on which a smoothing layer 15, a common electrode 16, and an insulating protective layer 17 are formed, and a liquid crystal layer 18 made of a liquid crystal composition sandwiched between opposing gaps between the active matrix substrate and the color filter substrate. 3, the source and drain wirings 7, 8 are mainly composed of molybdenum, It was composed of a laminated wiring of an alloy layer 3 containing at least one or more of chromium, titanium, tantalum and niobium which dissolves molybdenum as an additive element and an aluminum alloy layer 2. |
