PROBLEM TO BE SOLVED: To improve a wiring shape and to prevent an electrical contact with an ITO while preventing the occurrence of row disconnection in wiring and the increase of the number of processes. SOLUTION: The array substrate has a transparent board 1, a plurality of scanning lines 5 formed on the board, a plurality of signal lines formed on the board so as to cross the scanning lines, thin film transistors which are provided for all crossings between the scanning lines and the signal lines and which captures signals from corresponding signal lines on the basis of the voltages of corresponding scanning lines, and pixel electrodes 10 which are provided correspondingly to each thin film transistor and which receive signals captured by the thin film transistors. The signal line is laminated wiring consisting of a first metallic layer 17 formed on an insulation layer 9 and a second metallic layer 10 formed on the first metallic layer. The first and second metallic layers have the same main components and contain at least one element among silver, gold, or copper. |
