1. An array substrate comprising:

  • a display area in which pixel electrodes are formed,a scanning line formed of a low resistivity metal, said scanning line being arranged between the pixel electrodes,a signal line formed of a high melting point metal selected from the group consisting of chrome, molybdenum, tantalum and alloys thereof, said signal line crossing over the scanning line interposing an insulating layer therebetween,a first terminal to which a scanning signal is applied,an extended scanning line formed from a conductive film for connecting the scanning line with the first terminal, said extended scanning line being formed only of the same conductive film as for said signal line,an auxiliary capacitance line arranged parallel to the scanning line,a collected auxiliary capacitance line arranged in parallel to the signal line and electrically connected to the auxiliary capacitance line,a second terminal to which a common signal is applied, andan extended auxiliary capacitance line for connecting the collected auxiliary capacitance line with the second terminal for the common signal, said extended auxiliary capacitance line being formed only of the same conductive film as for said signal line, wherein the auxiliary capacitance line, the collected auxiliary capacitance line and the scanning line are formed from the conductive film of the same layer.
